Abstract:
All or part of 22 USGS 7.5' quadrangle-based wetland coverages were prepared for the Lake Champlain/Lake George watersheds within the New York State Adirondack Park using ArcGIS 9.3.1 at the Remote Sensing/GIS Laboratory, State University of NY (SUNY) Plattsburgh. Wetland delineations on 1:40000 color infrared NAPP air photo transparencies were scanned and geocorrected. Wetlands were digitized as line shapefiles in ArcGIS from the geocorrected scanned imagery using ArcGIS ERDAS Stereo Analyst extension. Individual quadrangrangle line shapefiles were merged into a single polygon and arc coverage, which was edited and attributed in ArcInfo. This wetlands database consists of both polygon and linear features labeled using National Wetlands Inventory (NWI) conventions as modified for use by the NYS Adirondack Park Agency. The wetland coverage was exported as an Arc Interchange File to the New York State, Executive Department, Adirondack Park Agency (NYS APA) running ArcInfo version 9.x.
Purpose:
The wetlands database is part of a larger database designed to help evaluate watershed/wetland relationships and provide data for cumulative impact assessments. The outreach efforts to share the Agency natural resource database will encourage resource appreciation and wise use, particularly in a regional context.
Supplemental_Information:
Color infrared transparencies with wetlands delineated on acetate overlays were scanned at 2000 dpi into tif files using an Epson Expressions XL 10000 scanner at the SUNY Plattsburgh Remote Sensing/GIS Laboratory. Air photos and their stereo pairs were geocorrected using the ArcGIS ERDAS Image Analysis extension, orthothoimagery from the NYS GIS Clearinghouse, USGS DEM files from CUGIR, and USGS camera calibration files. Transfer from acetate overlays to digital wetland arc shapefiles was done using the ArcGIS ERDAS Stereo Analyst extension, Sterographics CrystalEyes3 glasses and E-2 emitter. All digital files used the UTM Zone 18N NAD83 coordinate system.
Line shapefiles were appended into a single arc and polygon coverage with the outer boundary of the study area and the 7.5' USGS quadrangle boundaries. Digital wetland boundaries were edited in coverage format with a snapdistance 20.0 meters, snaptype closest, weed tolerance 3.0 meters, and a fuzzy tolerance of 1.219 meters. Wetland labels were added during heads-up editing with a customized on-screen menu using the georeferenced air photo acetate wetland overlays as a backdrop. Wetland label columns were concatenated into a unified wetland label using ArcInfo. Wetland labels follow the conventions established by Cowardin, L.M., V. Carter, F.C. Golet, and E.T. LaRoe. 1979. Classification of Wetlands and Deepwater Habitats of the United States. FWS/OBS-79/31. Office of Biological Services, U.S. Fish and Wildlife Service. U.S. Department of the Interior, Washington, D.C. 103 pp. Some modifications to the conventions were made to accommodate this project and are noted in the NWI label tables accompnaying this metadata. Files were transported to the NYS APA as ArcInfo export files (no compression) .

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attributes assigned to polygon features consist of unique User-Ids and wetland labels. Arc attributes include a unique User-ID, ARCVALUE to identify quadrangle and watershed boundaries, and wetland labels for linear wetlands. Quadrangle boundaries were temporary for the purposes of editing and attribution and were removed prior to creating the final coverage. Polygon and linear wetland labels were derived from photointerpretation techniques. Wetland labels were entered by georeferencing the scanned air photo acetate overlay of wetland delineations to the digital wetland coverage. To minimize typographical errors, both polygon and linear wetland labels were entered utilizing an on-screen menu consisting of columns representing wetland label components. Label columns were concatenated in ArcInfo to create a unified wetland cover type label. The NWILABEL item was visually checked on the computer screen for integrity and labeling accuracy. Polygon and linear wetland labels were summarized in ArcMap to identify nonsensical or illogical NWI labels, which were corrected in ArcInfo ArcEdit.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Value: Unknown
Attribute_Accuracy_Explanation:
Polygon and linear wetland cover type labels were derived from photointerpretation techniques. All photo overlays were checked by two independent interpreters for missing wetlands, uplands delineated as wetland, incorrectly delineated polygons, missing wetland labels, and incorrect wetland labels by two people in a prior project. Photo overlays were directly compared to the digital wetland files utilizing scanned copies of the photo overlays corrected to the wetland delineations. This process facilitated the entry of wetland cover type labels and to discover missing arcs. Digitized and scanned coverage hard copies were directly compared to orthophoto overlays to check for missing arcs. The process of digitally labeling the wetland coverages also helped to resolve some missing, incomplete, and nonsensical labels. Finally, all wetland labels were printed in tabular form and proof-read to ensure both complete labeling of the coverage and logical label content. No quantitative accuracy assessment was performed.
Logical_Consistency_Report:
Polygons: All polygons were required to possess either a wetland or upland cover type (i.e., a SYSTEM entry and therefore a final NWILABEL entry were mandatory). During the labeling process, digital polygons were checked for the presence of a label point and incomplete polygons were repaired.
Arcs: Only linear wetlands arcs received a wetland label. ArcMap was used to color-code linear wetlands to help discover those linear wetlands missing a label or those that were labeled improperly. Only linear wetlands were allowed to exhibit dangle nodes.
Inter-coverage consistency: Wetland labels and arcs along adjacent quadrangle edges were proofread using ArcMap and corrected in ArcInfo ArcEdit.
Completeness_Report:
Extensive quality assurance/quality control measures were taken for all steps of database creation. All wetland labels were reviewed for conformance to National Wetlands Inventory standards. It is expected that because the derivation of data from photointerpretation techniques, uncorrectable errors and mistakes may be present. Identifiable mistakes will be corrected as needed. These wetland maps contain only those wetlands that were identifiable from aerial photographs.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Horizontal positional accuracy has error potential from several different steps: photointerpretation, air photo rectification, and digitizing techniques.While great care was taken at every step, no formal quantitative accuracy assessment was conducted.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
No vertical coordinates are associated with this data set. Scanned air photo transparencies were geocorrected to orthhoimagery created from the same imagery. Topographic displacements in the NAPP imagery and derived wetland files were corrected using USGS DEM files.

Spatial_Data_Organization_Information:
Indirect_Spatial_Reference:
Wetlands are defined as polygons identified by a software-placed label point or as an arc labeled with a wetland cover type. Some arcs and polygons represent boundaries imposed by the study area boundary and therefore do not represent true feature boundaries. All non-wetland polygons possess a U SYSTEM and NWILABEL. All non-wetland arcs possess a blank cover type label.
