Description:
Abstract: Spatial data containing the 1916 Fire Protection Areas of the Adirondack Park, New York State.

Purpose: The spatial data layer was created for the Adirondack Park Agency (APA) as an historical reference. This resource may be used to determine the recent history of land use in the Adirondack Park and major disturbances to the landscape. Such known and documented disturbances include a series of major forest fires that occurred at the turn of the 19th Century.

Supplemental Information: The hardcopy color map from which this digital data set was created is printed on paper adhered to a cloth/linen backing and attached on the top and bottom to long wooden sticks. The different land codes are color-coded and described in the legend. Supplemental Information: Digital data was developed by for the area defined by the Oswegatchie/Black River watershed in by SUNY Plattsburg in conduction with the APA.

Process Description: Applied GIS, Inc. processing steps: The source map has latitude longitude lines printed over the protection zones. Intersections of these lines were used to generate a tic file of UTM coordinates representing the corners of 15-minute quadrangle map sections. A total of seventy tic marks were included in the file. This file was used to register the hardcopy map. Due to the large size of the original 1916 Fire Protection map (approximately 66 x 56 inches), the arcs were digitized in Arc/Info into twelve individual coverages. The projection of the coverages were defined using the PROJECTDEFINE procedure. The boundary of the Adirondack Park was copied into each coverage and arcs were digitized up to this boundary in each coverage. Digitizing was completed on a Calcomp 9500 digitizing tablet. The RMS error for the twelve map sections ranged from 0.001 to 0.023. The higher registration error for several map sections was due to some sections of the hardcopy map being too warped and fragile to flatten sufficiently. The twelve coverages were edge-matched then appended together. Common boundaries between polygons split between map sections were removed. Lists of intersections and dangling nodes were produced and used to rectify topology errors. The composite coverage was then built with the POLY option. Label points were created in the coverage and a new attribute field, "Value", was added. "Valid" codes for this field ranged from 1 to 7. The polygons of the coverage were coded for "Value" in ArcView. A look-up table called Firecodes.lut was created to cross-reference to the coverage. The list below indicates the description associated with each code. The final data set was converted into an Arc/Info interchange filed named fire.e00 for easy data transfer.

VALUEDESCRIPTION
1 GREEN TIMBER - virgin and second growth - no slash
2 LOGGED FOR SOFTWOOD ONLY - considerable slash
3 LOGGED FOR BOTH SOFTWOOD AND HARDWOOD - much slash
4 BURNED OVER AREA - much inflammable material left
5 WASTE AND DENUDED LANDS - very little inflammable material
6 OPEN LAND - farmland and grazing
7 WATER BODIES

Applied GIS, Inc. QA/QC analysis: Quality Assurance/Quality Control was determined by a series of tests. The final coverage was visually inspected interactively through comparison to the source material (the hardcopy map). The data set was thematically mapped by "Value" codes and printed in sections at the same scale as the source material. The printed check plots were positioned next to the source material for cross-examination. The operator checked for consistency between the source material and the final coverage in terms of coding and position of graphic objects and attributes (fields and content). The geographic extent was confirmed in two ways. First, the final coverage was zoomed to the full extent to identify potential outliers located beyond the 10-mile Adirondack Park buffer. Second, the boundary coordinates of the coverage were compared to the 10-mile Adirondack Park boundary coverage extent. Objects with extreme area size (small or large) were identified in ArcView by sorting the attribute table by area. Small slivers and unusually large polygons were examined and rectified as needed. The accuracy of the type of attribute fields was verified by examining the Arc/Info Items listing for the coverage. Creating a summary table in ArcView confirmed valid attribute values. Inconsistencies (e.g., missing values) were identified and rectified. The coordinate system of the final data set was verified by examining the coverage description in Arc/Info, as well as overlaying the data over a coverage known to be in the desired projection. Consistency between the known coverage and the final fire protection data layer was evaluated.
