          Forest Inventory for the State of Maryland                                                       Final Report









            Background



                   Salisbury State University's Image Processing & Remote Sensing Center was contracted in

            1992 by the Maryland Department of Natural Resources' Forest Service to perform a complete

            forest inventory of the State as part of, and in compliance with, the Forest Conservation Act of

            1991. Funding for the inventory came from a number of sources, including the State's 1992 309

            CZM Grant. The first year's effort is designed to provided to both the State and various jurisdic-

            tions (especially Counties) a series of maps and aggregate statistics on the type and distribution of

            forest cover throughout the State. The inventory is based on the derivation of forest signatures

            through computerized means from digital Landsat satellite data through the use of image process-

            ing, remote sensing and statistical techniques suitable for inclusion in a standard Geographic

            Information System (GIS). The data derived are being managed so that in a second year's effort

            they can be further analyzed for tracking purposes and to provide more detailed information on

            prioritized afforestation/reforestation sites and characteristics of the buffer areas adjacent to

            streams. This information will also be useful in the State's efforts to meet its nutrient reduction

            commitment under the 1987 Chesapeake Bay Agreement.

           Overview & Summaa of Tasks



                  1.     Acquire recent passes (leaf on and leaf off) TM to cover the entire state.

                  2.     Delineate forested areas with a minimum mapping unit of one acre for non-stream

                         associated areas and 100 feet for linear areas associated with streams and forest


                         corridors.

          Forest Inventory.for the State of Maryland                                                     Final Report


            Objectives and Methods:



                   The inventory produced at Salisbury State University's Image Processing & Remote Sensing

            Center used MIPS and ARC/INFO software to create maps and statistical summaries and their

            associated digital data. Statistical summaries were generated by county, watershed and subwater-

            shed so that specific information could be obtained for forest types within subwatershed compo-

            nents within individual counties. The data could also be aggregated to larger geographic and

            political units. Examples of the statistical tables for the Patuxent River Watershed can be found in

            the appendices.



            The minimum mapping unit is one acre for non-stream associated areas and one hundred feet for

            linear features associated with streams and forest corridors. Forest typing was done by using leaf

            on state-wide coverage from three full Landsat Thematic Mapper scenes and two map sheets

            acquired in Fall 1991. A second complete leaf-off data set was acquired for Spring 1992 to allow

            for future refinement of the forest cover in order to generate maximum cover type differentiation.

            Adjustments to the delineation and typing to permit mapping at a scale of 1:24000 were made by

            overlaying the analytically derived forest clusters from the Landsat data set over SPOT 10 meter

            panchromatic base maps.

           Sequential Procedure for Preparation of Digital Files;

           The process by which the final digital files representing polygonal forest data were created was as

           follows:

                         1.     Acquisition of digital Landsat Thematic Mapper data from EOSAT Corp. to
                                include full State of Maryland Coverage. Appendix I shows the scene selec-
                                tion process.


                         2.     Transfer of the digital data from open reel tape to disk. This was done on the

                                SSU Academic Vax.



                         3.     Rotation to true north and algorithmic correction for scene spectral variation,
                                as well as edge enhancement and contrast stretching. These routines were
                                done on the VAX minicomputer using ASTEPsoftware.


                         4.     Signature extraction through unsupervised clustering techniques. The Vax was
                                used to derive signatures by developing covariance matrixes of spectrally
                                significant classes of landcover. The resulting classes were mapped and those
                                corresponding to vegetative groups were analyzed and compared to sites for
                                which there existed detailed knowledge from field visits.


                         5.     Signature grouping and reextraction based on ground-truthing of test sites.
                                Two test sites (quads) for each county were initially selected and field data
                                from these sites was compared to the data generated by cluster analysis from
                                the Landsat scenes. Scene-tolerant signatures corresponding to Anderson
                                categories 41: Deciduous forest, 42: Coniferous forest, 43: Mixed Forest, and
                                44: Shrub/Scrub & Regenerating forest were computed and the scenes repro-
                                cessed to derive pixel-specific classification "maps".

          Forest Inventory for the State of Matyland                                                    Final Report


                          6.    Overlay of Watershed, Subwatershed and County bounda     ry files. The rasteriz-
                                ed data was combined with polygons representing the State's watersheds,
                                subwatersheds, and counties. Pixel counts were then made of classified pixels
                                that corresponded to the forest type and assigned membership according to
                                their inclusion in one or more of the overlay files.


                          7.    Polygon generation of forest types. A raster-to-vector conversion process was
                                developed on the VAX that created 'Polygons for each cluster of three or more
                                pixels that had been identified as belonging to one of the four forest type
                                categories. Islands of less than three pixels were filled and reclassified with
                                the adjoining classification except when adjacent to streams. In those instanc-
                                es where pixels of three or less grouping were adjacent to streams they were
                                allowed to form string polygons.


                          8.    Classification of polygons according to forest type. A set of decision rules was
                                employed to allow the forest class polygons to be classified according to their
                                prevailing forest type. Generally, the computer was instructed to examine
                                each polygon and evaluate the percentages and distributions of each of the
                                forest types within that polygon. If one type predominated, the polygon was
                                labeled by that type. If one type was most characteristic of the area, a
                                comparison table was examined in an attempt to achieve a minimum 40%
                                representation by the classification type. Cases of high density inclusion of
                                specific types and cases of large inclusion of non-forest islands were handled
                                separately by tagging for manual inspection and determination. Polygons were
                                classified as mixed forest type when no clear predominance of a type could be
                                established.
                          9.    Export of polygons and polygon attributes. Forest polygons derived in the
                                previous steps were exported in ASCII format by coordinate pair representa-
                                tion to PC-DOS compatible format using network interchange protocols.

         Forest Inventory for the State of Maryland                                                   Final Report


                         10.    Import of Vax-generated polygons into PC-ArcInfo. The polygon files devel-
                                oped above were brought into a coverage format file using Arclnfo's Import
                                algorithm. The data was cleaned and new polygons built.


                         11.    Joining and edge-matching of forest polygons. ArcInfo, was used to assemble
                                the polygon data from the three Undsat scenes and two Landsat. map sheets
                                into 18 files that were adjusted to cover the map extents of the 18 watersheds
                                of the State. The files covered geographically rectangular areas and thus over-
                                lapped to some extent.


                         12.    Intersection of County and Subwatershed Boundaries. Each watershed was
                                intersected with the subwatershed and county boundary files to allow categori-
                                zation of polygons into subwatershed and county units (multiple attribute
                                assignment). Polygons were rebuilt where they were intersected using ArcInfo.


                         13.    Conversion of ArcInfo Generate polygon files to MIPS rvf files. The polygon
                                files developed in step #12 were imported into MIPS rvf format and convert-
                                ed to be compatible with the projection and unit of measure inherent in the
                                .rvf SPOT satellite raster files (i.e. NAD 1927 State Plane and linear meters).
                                Reregistration was undertaken to match the two data sets. In most cases the
                                registration adjustments were minor since both data sets had been projected
                                onto a Space Oblique Mercator sphere.

         Forest haventoryfior the State of Mdqland                                                   Final Report


                         14.    Visual inspection of forest polygons with manual adjustment of boundaries.
                                The forest polygons originating from classified TM data were overlain onto the
                                SPOT panchromatic base and then adjusted where boundary mismatches
                                occurred. The adjustments followed general photogrammetric interpretive
                                principles.


                         15.    After adjustment the files were converted back to Arclnfo coverage format
                                and a final statistical series was produced. Appendix 11 summarizes the
                                acreage statistics for forest type grouped by County, Watershed, and Subwater-
                                shed. Appendix III contains a more detailed statistical breakdown for the
                                Patuxent River Watershed. Similar statistical breakdowns are available for the
                                other major watersheds of the State. Appendix III also contains a map
                                showing the geographic location of the Patuxent River watershed along with
                                maps showing the distribution of subwatersheds in the counties in which the
                                Patuxent River watershed is located. Similar maps are available for all,the
                                counties in Maryland.



           Forest Buffer Characterization:

                  A second undertaking involved the computation of forest buffers and the typing of streams

           according to their forested buffers. The procedure followed was:



                         1.     Computation of 100 and 300 foot stream buffers. ArcInfo was used to gener-
                                ate two files for each watershed containing the polygon data representing the
                                100 and 300 foot stream buffers. The source data was the stream file currently
                                used within the State and developed through the efforts of the Maryland
                                Office of Planning.


                         2.     Export of the buffer files and transfer of classified raster image files from the
                                minicomputer to the PC. The Arclnfo buffer files were exported to a MIPS

                               files previously resident on the VAX. The resulting files were visually inter-

                               distribution of streams and subwatersheds in the Watershed. Stream reaches
                               were classified as to whether they had forest buffers on one or both sides and
                               with widths of at least 100 or 300 feet.



           Hardgopy Map Generation:

                  The final process in generating the data onto a map base was done in two steps.

                         1.    A procedure was developed to generate mylar plots using ArcInfo by subwat-
                               ershed of the streams, 300 foot buffers, forest polygons by forest type and
                               subwatershed boundaries at a scale of 1:62500. The mylar may be placed over
                               the appropriate County topographic map.


                         2.    A second procedure was developed to overlay the forest data, subwatershed
                               and watershed boundaries, streams, and 300 foot stream buffer on 7.5 minute
                               quad SPOT base imagery using MIPS software. Appropriate cultural (e.g.
                               transportation) and geographic (e.g. streams) are included. An example of a
                               forest inventory 7.5 minute quadmap is also included in Appendix V.


           Digital Layers:

                  The data plotted and printed in the previous steps is also available as digital layered

           information for analysis and display using a GIS. Enhancement of the data through common

           registration will allow comparison with the 100 year flood plain and critical area boundaries as well

           Likewise, comparison to the Maryland Office of Planning data sets is also possible, and, may be

           especially useful in reference to MOP's Land Use/Land Cover data



           Utilization of Forest Inventm- in Associated Study of Forest Interior Dwelling Bird

           Habitat:


                  In an associated study, Salisbury State University's Image Processing Center has agreed to

           map Forest Interior Dwelling Bird habitat by the following process:



                  1.     Using photo interpretation and ground truthing, develop techniques for delineating
                         size classes. These size classes are expected to be at least su fficient to identify less
                         than pole, pole, and greater than pole sizes of forest stands.


                  2.     Combine forest size class data and cover type data with acreage guidelines provided
                         by the Nongame & Urban Wildlife Program to delineate Forest Interior Dwelling
                         Bird habitat.



                  3.     Produce digital files at a minimum scale of 1:24000, 7.5 minute quad based, of Forest
                         Interior Dwelling Bird Habitat.


                  4.     Produce hard-copy maps delineating Forest Interior Dwelling Bird habitat by county
                         at a scale of 1:62500 (1:63360).


                  5.     Provide summary statistics for Forest Interior Dwelling Bird habitat statewide and by
                         county, physiographic region, and Critical Area.

           PROJECT SCOPE - 1993 CONTINUATION EFFORT:






           BackgLound



                 In addition to performing a complete forest inventory of the state as detailed above, the

           Forest Conservation Act of 1991 requires the Department of Natural Resources to develop

           procedures to review State sponsored development plans and associated forest stand delineations

           and forest conservation plans, and to review local forest conservation programs and assess their

           effectiveness in promoting the conservation of forests as required by the Act. The following

           objectives and tasks were developed by the DNR Forest Service and:Salisbury State University's

           Image Processing & Remote Sensing Center AND 1993 CZM Section 309 grant funding requested

           in order to address these requirements.





           Ob -jectives

                 To facilitate the use of the forest inventory by the Forest Service and counties in tracking

           development activities, and in prioritizing sites for and monitoring the integrity of retained and

           planted forests.

          Forest Inventory for the State of Maryland                                                     Final Report


            Tasks




                   1.     Modify the existing forest resource inventory database to include refinements of the
                          delineation based on a comparison of two dates of Thematic Mapper information
                          (one leaf on, one leaf off). Relevant ancillary information will be included as
                          appropriate.


                   2.     Develop methodologies for using the forest inventory in  conjunction with other data
                          bases to prioritize the areas best suited for forest retention, and for reforestation and
                          afforestation activities.



                   3.     Develop project tracking systems for the State and local jurisdictions to ensure
                          compliance with the provisions of the Forest Conservation Act and the long-term
                          protection of designated retention, reforestation and afforest ation areas, as well as
                          areas protected and exempted under declarations of intent.


                   4.     Develop a computerized data base on land use, land ownership and other features
                          pertinent to conservation of, forest cover, linked to the forest inventory geographic
                          data base, for those counties within the State for which the Service has direct
                          responsibility.


                   5.     Demonstrate the content and utility of the forest resource inventory to personnel of
                          the Forest Service and local jurisdictions, and solicit suggestions on what additional
                          information and capabilities are needed to ensure effective tracking of development
                          projects and associated forested areas in order to meet the requirements of the State
                          Forest Conservation Act..


                   6.     Incorporate changes suggested by users of the inventory and develop ancillary data
                          layers and methodologies to increase the utility of the inventory and improve
                          effectiveness of the tracking systems.
