                1. STATEMENT OF PROJECT PURPOSE

                This grant employs James City County as a pilot project.                      Several
                methods of data entry have been tested to determine the optimum
                technique or. approach for database entry for similar Department of
                Conservation and Recreation (DCR) natural resource information.                    For
                each approach applied, the data has been compiled, and exhibited using
                Arc/Info. A comparison of these methods including data accuracy, data
                output, and the time required for each method.                 The following data
                elements for James City County/City. of Williamsburg are included in
                this pilot project:    existing beaches, state parks, a summary of Natural
                Heritage areas data, cultural resources within one-half mile of tidal
                water bodies, public access sites and private access sites.

                11. METHOD A


                Overview of Tasks Required for Method A

                This method uses the James City County/City of Williamsburg map and
                matrix from the Chesapeake Bay Area Public Access Plan. Each of the
                points and polygons associated with the data shown on this map has
                been digitized three times to establish the error due to data accuracy.
                The data accuracy, process, and time required to complete this method
                have been documented.            The steps outlined in the Scope of Work
                (Appendix A) are described below.

                Ste12 1 *   The Council on the Environment VA Ecomaps produced and
                original base map at 1:100,000 scale of the James City County/City of
                Williamsburg. This base map was reproduced to provide a base with the
                appropriate      longitudinal      and    latitudinal    reference      points      for
                digitization    This base map was reproduced on the large plotter to be
                identical to the one used for the Chekapeake BaY Area Public Acces
                Plan.


                SteI2, 2. A mylar was made of this base map at 80% of the original. This
                step was necessary to obtain a base which contained the longitudinal
                and  latitudinal reference points at the same size as the camera-ready
                copy for the Chesageake Bay Area Public Access Plan.

                Step  3, The camera-ready overlays were then re-registered to the new
                base  containing the reference points.








             Stel2 4.  Using Arc/info the geogra  phic information from the camera-
             ready mylar, several coverages were created and digitized.          These
             coverages include:
                   EROSION
                      This coverage includes all shoreline erosions and was digitized
             as polygons.

                   HERPOLY
                   This coverage includes all the Natural Heritage areas identified in
             the Plan. These areas was digitized as polygons.

                   CULTURAL
                   This coverage includes label   points which indicated the location
             of the sized-points with a symbol.

                   BEACH
                   This coverage includes beaches and was   digitized as a line.

                   ACCESS
                   This coverage includes all the public and private access points.
             Each access site is identified with a #-symbol attached to the point
             location at the time of digitization

                   LINE
                   This coverage includes all the lines which are used as leader
             lines and connectors for labeling symbols on the various coverages.

             Step  5. The Procedure Used for Digitizing Includes the Following Steps
                   A.  The first coverage was created and the four reference points
             were  digitized. The Root Mean Square (RMS) Error reading was .002.

                   B. Using the TIC and BND files from the first coverage that was
             digitized, all other coverages were digitized and saved.

                   C. To avoid having to CLEAN the coverages, the INTERSECTARC and
             ARCSNAP environment were used during the digitizing sessions. The
             coverages were then edited. Dangle nodes were deleted, arcs modified,
             and label points were checked for uniqueness.      Coverages which had
             errors were modified and changes were saved.

                   D.  Each coverage was then BUILD using the appropriate option.
             Topology was constructed by BUILD identifying arcs that made up each
             polygon, and associating a label point with each polygon.

                   E. Since the original base was in UTM meters, the coordinates of
             the coverages that were digitized had to be transformed from the
             digitizer's inches to UTM meters prior to a determination for the level
             of accuracy.    A PROJECTION was executed to ensure there was a
             relationship between locations on the coverage and their true location.
             The PROJECT command calculates the UTM coordinates for each of the
             digitized tics. After the PROJECTION, the ARC CREATE command was
             used to create an empty coverage with the UTM coordinates as its tics.
             INFO was initiated to update the empty coverage.         The tic file was
             selected and the UTM values were entered for the four reference tics
             obtained.from the output of th PROJECT command. INFO was then exited
             after the completion of the ADD command. New coverages with UTIVI
             tics were then created from each digitized coverage.            Finally, a
             transformation was performed to calculate and display the Root Mean
             Square (RMS) Error.      The RMS error were -calculated at 0.10 inches
             (input) and 30.848 UTM meters (output).      The nationally accepted eror
             for a 1:100,000 scale map is 50 meters.

                   F. The text and pointers were added to the coverages to indicate
             the type of point locations.     A separate coverage was created and
             named POINTLAB. This coverage contains label points which correspond
             to lines (arcs) in the POINTERS>UTM18 coverage. These points were
             used to indicate the location of the text. The FORM command was used
             to input the label attributes at the different locations.   The coverage
             was saved. POINTLAB was then BUILD in ARC with the POINT option.

             Step 6.     The attributes were entered for the public, private and
             potential access sites as shown on the James City County/City of
             Williamsburg matrix found in the Chesageake Bay Area Public Access
             Plan . The following, procedure was followed for this step:
                   1. Initiate INFO.

                   2. A database was created (SITE.DESCR)

                   3. The items to be included in the database were named and
             described.   Characteristics included in the description are item width,
             output width and item type.

                   4. Records were then added to the database using ADD command.
             Once the records were added, INFO was exited.

                   5.   Key values    1, 2, or 3 representing PUBLIC, PRIVATE or
             POTENTIAL respectively were assigned to the access related items in
             the database.   ARC was inititated for the assignment of these values.
             The ADDITEM command was then used with the appropriate options in
             assigning key values to the access sites.

                   Below is a list of items in the database, and the Key Value for
             each.

              Accuracy

              The most important aspect of map accuracy relates to the original data.
              The original base map was plotted at 1:100,000 and was reduced to by
              80% of the original for the Cheso-eake BaV Area Public-- Access Plan
              The original overlays were created to fit the reduced version of the
              map. This obviously resulted in some distortion and inaccuracy in the
              development of information at this scale. In calculating the RMS ERROR
              for a map at a scale of 1:100,000, the results should be 50 meters in
              UTM meters.


              The coverages for Method A were digitized three times. Four tics were
              entered the first time the data was digitized.    Five tics were used -for
              digitization of the coverages the second and third time.      Listed below
              are the results of these digitizing sessions:
                          RMS ERROR (input)             RMS ERROR (output)

              3rd Time,          0.008                  25.920



              Time Requirements
              The time period was      documented for the steps taken to complete
              Method A may vary with relation to the amount of data present in other
              counties.


              Prior to digitizing the coverages, the following decisions were made:
                    1) Naming the coverages
                          2)  Deciding what will be digitized in each coverage
                          3)  Assigning lDs to items in each coverage
                          4) Deciding how each coverage will be digitized and build
              as (arcs, label, line, etc.)

             transformation.
             TIME: 2 Hours

             To create an additional coverage, the text location was specified, the
             coverage built, and the form command used to input the label
             attributes.

             Evaluation of Method A
             Method A is an example of the direct application of using a work
             product which was originally produced in a manual format and entering
             this data into a geographic information system.           The problems
             encountered with this technique relate to the base maps which were
             trimmed to fit on a standard 17" x 22" sheet size. This process caused
             some of the tic IlDs to be eliminated from the original base map. When
             the original tic IlDs are not located on the base map a process to


                                                6









             relocate these IDs must be followed as in the case of James City
             County.   A second problem occurred in relocating the tic IDs on the
             original base map if the map was reduced to fit the standard 17" x 22"
             sheet.    There is a degree of error inherent in the process of
             transferring the tic IDs and working with a reduced base map.



             Ill. METHOD B



             Method B was eliminated from the work plan as the level of efficiency
             is much greater with the use of a digitizer.

             IV. METHOD Q


             Overview of Tasks for Method C


             Method C involves the use of the original sources of data as the source
             for digitizing and assigning attributes to the geographic information
             presented in the Chesapeake Bay Area Public Access Plan.

             Step 1: Digitize the geographic points from the original data sources.
                   a)  Natural Heritage Areas - Natural Heritage Area data was not
             available on 7.5 minute USGS quad sheets, The compilation of data for
             the Chesapeake Bay Area Public Access Plan was determined to be the
             most appropriate and the original' data source for this information.    The
             original sheets are on 1:100,000 USGS photocopied maps prepared for
             the Chesapeake Bay Area Public Acces@ Plan and permanently retained
             in the Department of Conservation and Recreation, Division of Natural
             Heritage.

                   b)   Cultural Resources - The cultural resources national register
             properties located within one-half mile of a water body were
             transferred from the Department of Historic Resources 7.5 minute
             OSGS quad sheets to each of the county maps for use in the Chesageake
             Bay Area Public Access Plan. For the purposes of this method, the
             information located on the original Department of Historic Resources
             7.5 minute quad sheets were transferred to photocopies of 7.5 minute
             quad sheets covering James City County and the City of Williamsburg.
             In addition to the National Register sites, state register and National
             Historic Landmarks were included in the inventory.         A total of 22
             historic sites which are on the register were identified.    Eighteen (18)

             of these sites are within one-half mile of a water body.      These sites
             were transferred to a mylar prior to digitizing.

             The following are the transformation results after digitizing this data:

             c) Existing Beaches
             The beach locations were marked    on photocopies of the 1:100,000 scale
             USGS quad sheets by the Shoreline Programs Bureau of the Department
             of Conservation and Recreation.     Longitudinal and latitudinal data also
             obtained from the Shorelines Programs Bureau for these beaches were
             entered during this step to test the accuracy of this data versus the
             information marked on the photocopied USGS maps. It was determined
             that the photocopied data was superior to the point locations available
             in logitude and latitude.

             d) Shoreline Erosion
             The Tidewater Inventory document published by the Virginia Institute
             of Marine Science (VIMS) was transferred to photocopies of the
             1:100,000 scale USGS maps.          This data was used to digitize the
             shoreline information.    The rating used for shoreline erosion was
             classified in this method as follows:
                         Slight or none - less than 1 foot. per year
                         Moderate - 1 to 3 feet per year
                         Severe - greater than 3 feet per year
             Moderate and severe slopes were digitized.

             e) State Parks
             The Land Classification Maps developed by DCR for the location of York
             River State Park were evaluated for use in entering the park
             boundaries.    Since these maps did not contain geographic reference
             points, the USGS 7.5 minute quad sheet boundary was used.

             f) Public Access Sites
             The 1:100,000 scale USGS maps were used as the original source to
             record the sites found in the Chesapeake Ba)@ Area Public Access Plan.
             The site locations were transferred to 7.5 minute USGS quad sheets for
             digitizing.  Individuals within DCR who had field checked these public
             acess sites for the inventory verified their location.

             g) Private Access Sites
             The location of the sites were taken from the county maps found in the
             Chesapeake Bay Area Public Access Plaa. The location of the private
             access sites were verified using aerial photography and transferred to
             7.5 minute USGS quad sheets.

             h)   Potential Access Sites
             The location of the sites were taken from the county maps found in the
             Chesageake Ba    -y Area Public Access Plan. The location of the potential
             access sites was verified by individuals familiar with the location via


                                                   9









             a site visit. The locations were then transferred to 7.5 minute USGS
             quad sheets.

             The steps for digitizing the  categories or coverages listed above were
             are outlined below.


                         DIGITIZING:
                         Using the USGS quad sheets , a naming convention was
             established and several coverages were created and digitized.         It is
             recommended that the naming convention for USGS quad sheets which
             is consistent with that used by the Council on the Environment be
             followed.


                         1. For each coverage, eight (8) tics were digitized.

                         2.   SNAP ENVI RONM ENTS were established for polygon
             coverages to avoid having to CLEAN.

                         3. POINT and POLYGON coverages were digitized for USGS
             quad sheets which contained information.

                         TRANSFORMATION:
                         The coordinates of the coverages when digitized were
             transformed from UTM meters to the digitizer's inches using the
             TRANSFORMATION comand. The level of accuracy was determined by
             transforming the data back to UTM meters.

                         1. A file was created using the EDITOR, and the longitude
             and latitude of the digitized tics entered into the file.




                                                10








                         2.  A projection was performed for latitude and longitude to
             UTM, to ensure that there is a known relationship between locations on
             the coverage and their actual location

                        .3.    An empty coverage was created with the UTM
             coordinates as its tics.


                         4.   INFO was initiated and the tic values in the empty
             coverage were replaced by the UTM values using the UPDATE command.

                         5.   New coverages were then created from each dititized
             coverage using UTM tics.

                         6.   TRANSFORMATION was performed to calculate and
             display the Root Mean Square (RMS) Error. The calculation was achieved
             by the tic locations in the old coverage (digitizer's file) being compared
             to the input tics in the new coverage.

                         7.   Polygon coverages were appended, edited and cleaned
             using the appropriate commands.         Point coverages were built and
             appended.

             STEP 2:
             The attributes for the public private and potential access sites as
             shown on the James City County/City of Williamsburg matrix.
             Additional attributes were added for the Cultural Resources and
             Existing Beaches in this method.      An input form which serves as a
             screen entry form was also created for use in updating records.

             PROCEDURE
             1. INFO was initiated.


             2.    Separate datafiles were created for access sites, cultural
             resources, existing beaches and shoreline erosion.

             3.     Items in the different datafiles were named and their
             characteristics were described.

             4. After creating the datafile, the INPUT FORMS were created by using
             the SELECT command to select the DATAFILE.

             5. After selecting the datafile, the INPUT FORM com-mand was used
             with the name of the datafile to create the INPUT FORM.









             6. 'Responses were made to the LINE<COLUMN<CONTENT> prompt to
             indicate the location of the line on the sceen, the content of the line,
             and the restrictions regarding what values can or must be added.

             Accuracy

             The original sources for, the information varies, consequently, the
             accuracy level of the data varies with each original source. The intent
             of this method. was to use the original sources which were primarily
             7.5 minute USGS quad sheets or 1:100,000 USGS quad sheets for direct
             entry of digitized data.

             The coverages for Method C were digitized three times. Tic lDs were
             entered for each USGS quad sheet used in digitizing the information.

             Time Requirements

             The time required for the entry of data for Method C is documented
             below. The time required for completion of this method will vary with
             regard to the availability of the original base data sources for each
             county and the amount of data present in other counties.

             Evaluation of Method C
             Method C involves the digital entry of geographic information from the
             original source.  The original source in this case usually relates to the
             information or maps used for the transfer of information to the county
             maps found in the Chesapeake BaZ Area Public Access Plan. The
             problem with this method and the data,used relates to the accuracy of
             the original data.    Although much of the original data was field-
             checked, some data such as private access sites were not verified.
             Other data was transferred or interpretted from other maps, historical
             site records, or written materials for the purpose of completing the
             Chesal2eake BaZ Area Public Access Plan. Significant time was also
             spent to retrace the availability of original source material and in
             some cases to transfer this original base material to a USGS 7.5 minute
             quad sheet. This time was not reported in the above Time Requirements
             section.


             V. COMPARISON OF METHODS AND RECOMMENDATIONS


             The time requirements for Method C almost double those required for
             Method A. In theory, Method C should be more accurate than Method A;
             however, in the case of this James City County/City of Williamsburg
             pilot project, the inaccuracies shown in the comparison of methods are
             predominantly due to human error in locating sites or transferring
             sites to the map used in the Chespeake BaZ Area Public Access Plan.
             The level of accuracy found on the Chesapeake BaZ Area Public Access
             Plan maps and on the digitized information from these maps is
             adequate for regional planning applications.

             Because of the difference in time required for the two methods and the
             probable use of the digitized geographic information for large scale,
             regional planning, an overall application of Method A is recommended,
             However, prior to digitizing the information contained on the
             Chesapeake Bay Area Public Access Plan maps, the information should
             be field checked and/or verified using aerial photography.           This'
             verification step should eliminate most of the error and inaccuracies
             shown for Method A during the comparison of Methods A and B.

             Work Plan for scope of work entitled: GEOGRAPHICALLY REFERENCE
             CHESAPEAKE BAY PUBLIC ACCESS DATA, EXISTING BEACHES, STATE PARKS,
             AND A SUMMARY OF NATURAL HERITAGE AREAS DATA FOR ECOMAPS USING
             JAMES CITY COUNTY AS A PILOT AREA.

                                       August 9, 1990

                 The scope of work for this grant outlines five elements. A
             detailed description and work plan with projected target
             completion dates for each of these elements follows.

             1. PURPOSE
                 Using James City County as a pilot project, several methods
             of data entry will be tested to determine the optimum (most
             desirable) technique or approach to database entry for similar
             Department of Conservation and Recreation (DCR) natural resource
             information. For each approach applied the data will be compiled
             and exhibited using Arc/Info. Comparisons will be mad between
             the various methods or approaches used. These comparisons will
             determine the accuracy of the product or data-output in relation
             to the time expended for data entry. The following data elements
             for James City County/City of Williamsburg will be included for
             each method used in this pilot project: existing beaches state
             parks, a summary of Natural Heritage areas data, cultural
             resources within one-half mile of tidal water bodies, public
             access sites, and private access sites. Attributes for the
             public and private access sites should be recorded from the James
             City County/City of Williamsburg matrix which corresponds to the
             map.

                 Target Dates for this portion of the scope of work follow:
                 Method A - October 31
                 Method B - December 31
                 Method C - February 28

             A description and step-by-step   process for each method to be used
             in this pilot project are outlined below.

                 METHOD A: OVERVIEW
                 -Using the James City County/City of Williamsburg map which
                 has been completed for the Chesapeake Bay Area Access Plan,
                 digitize the geographic data points. 'Digitize each of these
                 points three times to establish the error due to data
                 accuracy.

                 STEP 1 Have the Council on the Environment, Virginia ECOMAPS
                 make a base map at 1:100,000 scale of James City County/City
                 of Williamsburg.    Do not rim this base map and be certain
                 this map has at least four longitudinal and latitudinal
                 reference points.

                 STEP 2 Make a mylar of the untrimmed base at 80% of the
                 original.

                 STEP 3 Transfer the registration ticks from the original
                 mylar base which will be used as the camera-ready copy for
                 the Chesapeake Bay Area Access Plan to the new base which has
                 at least four longitudinal and latitudinal reference points.

                                               1                        J01524/PRR









                STEP 4 Register the camera-ready mylar overlays showing
                cultural resources, Natural Heritage areas, state parks,
                public access sites, and,potential access sites to the new
                base.

                STEP 5 Using Arc/Info digitize the geographic information
                from the camera-ready mylar overlays which have been prepared
                for the Chesapeake Bay Area Access Plan.

                STEP 6 Enter the attributes for the public, private and
                potential access sites as shown on the James City County/City
                of Williamsburg matrix.

                STEP 7 Document the process, time, and ease of completion
                using this method.


                METHOD B: OVERVIEW
                Translate the Chesapeake Bay Access Plan data shown on the
                James City County/City of Williamsburg to an original
                mylar(s) made from the 1:100,000 scale USGS maps. Use the
                longitudinal and latitudinal location points taken from the
                1:100,000 scale USGS maps to record the geographic data into
                Arc/Info.

                STEP 1 Order from USGS or have A & E supply reproduce an
                original mylar(s) of the 1:100,000 scale USGS maps which show
                James City County/City of Williamsburg.

                STEP 2 Translate the information mapped for the       Chesapeake
                Bay Access Plan on to the 1:100,000 scale mylar(s).

                STEP 3 Determine the latitudinal and longitudinal locations
                for each of the geographic points recorded on the maps.

                STEP 4 Enter the latitudinal and longitudinal locations for
                the mapped points into Arc/Info.

                STE P 5 Enter the attributes for the public, private, and
                potential access sites as shown on the James City County/City
                of Williamsburg matrix.

                STEP 6 Document the process, time, and ease of completion
                using this method.


                METHOD C: OVERVIEW
                Use the original sources of data to digitize the geographic
                points shown on the Chesapeake Bay Area Access Plan map.

                STEP 1    Digitize the geographic points shown on the
                Chesapeake Bay Area Access Plan map using the original data
                sources as follows:
                a)   Natural Heritage Areas - 7 1/2 minute USGS quad sheets
                     located in the Division of Natural Heritage in DCR.






                                             2                       J01524/PR.R









                 b)   Cultural Resource Areas - 7 1/2 minute USGS quad sheets
                      for standing and archeological sites which are on the
                      National Register of Historic Places and are within 1/2
                      mile of a water body. These maps are located in the
                      Department of Historic Resources.

                 C)   Existing Beaches       1:100,000 scale quad maps which
                      indicate beaches according to the Shoreline Programs
                      Bureau of DCR.

                 d)   Shoreline Erosion - Use the Tidewater Inventory document
                      published by the Virginia Institute of Marine Science
                      (VIMS) or obtain longitudinal and latitudinal location
                      points for shoreline erosion which exceeds 2 feet per
                      year from the VIMS.

                 e)   State Parks - Use   the Land Classification maps being
                      developed by DCR to digitize the location of the York
                      River State Park.

                 f)   Public Access Sites    1:100,000 scale USGS maps which
                      were used to record the sites recommended and the sites
                      not recommended for inclusion in the Chesapeake Bay and
                      Susquehanna River Public Access Guide.

                 g)   Private Access Sites - Verify the locations of these
                      access points as shown on the Chesapeake Bay Area Access
                      Plan map of James City County/City of Williamsburg using
                      aerial photography.    Digitize the private access data
                      from the Chesapeake Bay Area Access Plan map once the
                      site locations have been verified using aerial
                      photography.

                 h)   Potential Access Sites - Digitize the potential access
                      site data from the Chesapeake Bay Area Access Plan map
                      of James City County/City of Williamsburg.

                 STEP 2 Enter the attributes for the public, private          and
                 potential access sites as shown on the James City County/City
