1.2 Description
1.2.1 Abstract: A set of 53 USGS 7.5'
quadrangle‑based wetland coverages was prepared
for the St. Lawrence River watershed, primarily within the New York State
Adirondack Park (Table 1) using PC Arc/Info 3.4D+ at the Remote Sensing
Laboratory, Plattsburgh State University (RSL).
Wetlands were delineated on 1:40000 color infrared NAPP transparencies,
transferred to orthophoto overlays using an Image Interpretations Systems
Stereo Zoom Transfer Scope, and either hand digitized or scanned into PC
Arc/Info format. A digital file extracted from the watershed data layer defined
the outer boundary of the mapped area. This wetlands database consists of both
polygon and linear features labeled using National Wetlands Inventory
conventions. The 53 individual quadrangle files were exported to the
1.2.2 Purpose: The wetlands database is part of a larger database designed to help evaluate watershed/wetland relationships and provide data for cumulative impact assessments. In addition, the St. Lawrence River Watershed projects (Parts I and II) seek to analyze several large wetland complexes. These projects also endeavor to assist large landowners identify management concerns. The outreach efforts to share the Agency’s natural resource database will encourage resource appreciation and wise use, particularly in a regional context.
1.2.3 Supplemental Information: Line
drawings for 53 quadrangle‑based wetland coverages
were scanned using an ANAtech Evolution scanner
housed at the Adirondack Park Agency. Digital files were vectorized,
transformed into the UTM coordinate system, edited, and attributed by the
Remote Sensing Laboratory,
Digital
files were georeferenced into a digital quadrangle file containing four
bounding tics using PC Arc/Info 3.4D+. Maximum allowable RMS was 0.003, snapdistance 20.0 meters, snaptype
closest, weed tolerance 3.0 meters, and a fuzzy tolerance of 1.219 meters. Hard
copies of the digital coverage showing arcs, dangle
nodes, and label points were carefully checked against the line overlay for
digitizing or scanning accuracy. Wetland
labels were added as label components using a digitizer menu customized for
this project. A label overlay was placed
over the line drawing, and arc and wetland labels were assigned on the
digitizer. Wetland label columns were
concatenated into a unified wetland label using dBase IV. A hard copy of the wetland coverage was made
showing NWI wetland labels and each label was checked against the label
overlay. Wetland labels follow the
conventions established by Cowardin, L.M., V. Carter,
F.C. Golet, and E.T. LaRoe.

2 Data Quality Information
2.1 Attribute Accuracy
2.1.1 Attribute Accuracy Report:
Attributes assigned to polygon features consist of unique User‑Ids, quadrangle identification codes, and wetland labels. Linear attributes include a User‑ID (to distinguish between quadrangle borders, the study area boundary, and wetland arcs), ARCVALUE to uniquely identify the quadrangle borders throughout the study area, and wetland labels. Polygon and linear wetland labels were derived from photointerpretation techniques. Wetland labels were entered by superimposing the orrthophoto label overlay upon a hard copy of the wetland coverage arcs and labels on a digitizing table. To minimize typographical errors, both polygon and linear wetland labels were entered utilizing a digitizer menu consisting of columns representing wetland label components. Label columns were concatenated in dBase IV to create a unified wetland cover type label. Hard copies of wetland coverages were printed and labels were individually checked against the orthophoto overlays. Arc User‑IDs and ARCVALUE were visually checked on the computer screen for integrity and labeling accuracy.
2.1.2 Quantitative Attribute Accuracy Assessment
2.1.2.1 Attribute Accuracy Value: unknown
2.1.2.2 Attribute Accuracy Explanation:
Polygon and linear wetland cover type labels were derived from photointerpretation techniques. All photo overlays were checked by an independent interpreter for missing wetlands, uplands delineated as wetland, incorrectly delineated polygons, missing wetland labels, and incorrect wetland labels. Photo overlays were directly compared to orthophoto overlays utilizing a Kail Reflecting Reducer/Enlarger. This process helped to verify the transfer 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. A hard copy was made of each coverage and both arc and wetland labels were compared to the orthophoto overlays. Linear wetlands were color‑coded to facilitate proofing. Finally, all wetland labels were printed in tabular form and proof‑read to ensure both complete labeling of the coverage and logical label content.
2.2 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. All wetlands were digitized (or for scanned files, transformed) into a blank quadrangle file containing quadrangle boundaries and tics.
Arcs: Only linear wetlands arcs received a wetland label. Printouts were made color‑coding 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.
General: PC Arc/Info's DISSOLVE program was used to identify adjacent polygons inappropriately possessing the same wetland label, and to identify arcs that should have received a wetland label but did not.
Inter‑coverage consistency: PC Arc/Info's EDGEMATCH routine was utilized to match arcs between coverages. Wetland labels along adjacent coverage edges were proofread using ArcView 3.1 and corrected in PC Arc/Info ArcEdit.
2.3 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.
2.4 Positional Accuracy
2.4.1 Horizontal Positional Accuracy
2.4.1.1 Horizontal Positional Accuracy Report:
The outer arc of all individual quadrangle‑based wetland files correspond to USGS 7.5' quadrangle boundaries. Wetlands were digitized or transformed (scanned files) into the quadrangle template with a UTM Zone 18 projection and metric coordinates. Horizontal positional accuracy has error potential from several different steps: photointerpretation, transfer to orthophotos, and digitizing techniques. Maximum allowable RMS error was 0.003 for each digitizing session. While great care was taken at every step, no formal quantitative accuracy assessment was conducted. An attempt was made in all mapping operations (delineation, transfer, digitizing) to have horizontal accuracy correct to plus or minus one pencil width (about 12 meters at 1:24000).
2.4.2.1 Vertical Positional Accuracy Report:
No vertical coordinates are associated with this data set. Topographic displacements of air photo delineations were corrected to match USGS orthophoto quadrangles using an IIS Stereo Zoom Scope.

3 Spatial Data Organization Information
3.1 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 quadrangle borders and therefore do not represent true feature boundaries. All non‑wetland polygons possess either a U SYSTEM and NWILABEL or have blank wetland cover types (outside the study area). All non‑wetland arcs possess a blank cover type label.
