1.2 Description
1.2.1 Abstract: A 7.5' USGS quadrangle-based coverage developed on PC
ARC/INFO 3.4D and 3.4D+ at the State University of New York at Plattsburgh,
Remote Sensing Lab (SUNY-Plattsburgh). Wetlands were delineated on 1:58000
color infrared NHAP imagery, transferred to orthophoto overlays using a B&L
Stereo Zoom Transfer Scope, and either hand digitized or scanned into PC
ARC/INFO format. The outer boundary of the study area is defined by a digital
file extracted from the watershed data layer. This wetlands database consists of
both polygon and linear features labeled by National Wetlands Inventory
conventions. Extensive quality control and quality assurance measures were taken
(see section: DATA QUALITY INFORMATION). The 48 individual quadrangle
files were exported to ARC/INFO 7.0 New York State, Executive Department,
Adirondack Park Agency (NYS APA) and were added as a layer to the O/B
ARC/INFO Library.
1.2.2 Purpose: The wetlands database is part of a larger database designed to help
evaluate watershed/wetland relationships. The project was funded by a grant from
the U.S. Environmental Protection Agency to NYS Adirondack Park Agency who
subsequently subcontracted the development of the wetlands data to
SUNY-Plattsburgh.
1.2.3 Supplemental Information: Nineteen quadrangle-based wetland coverages
(Beaver River, Big Moose, Bisby Lake, Black Creek, Copper Lake, Eagle Bay,
Fine, Five Ponds, Limekiln, Nehasane Lake, Old Forge, Oswegatchie SE,
Oswegatchie SW, Otter Lake, Soft Maple Reservoir, Stillwater, Stillwater
Mountain, Thendara, and Woodgate) were scanned by Computer Sciences
Corporation, Rockville, Maryland. The remaining 29 quadrangles were manually
digitized from orthophoto wetland boundary overlays into individual quadrangle
files consisting of the quadrangle boundaries and four bounding tics using PC
ARC/INFO (see 1.13 Native Data Set Environment). 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 coverage (arcs, dangle
nodes, label points) were carefully checked against the orthophoto wetland
overlay for digitizing accuracy by two individuals.
Wetland labels were added as label components using a digitizer menu
customized for this project. The orthophoto label overlay was placed over a hard
copy of the wetland coverage (labels and arcs) and labels 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 orthophoto label overlay.
Edits of arcs, label points, and wetland labels were made using either the digitizer
or screen, as appropriate.

Agency; Office of Wetlands Protection; State Wetlands Protection Program; Grant No.
X-002777-01-0 to the Adirondack Park Agency in cooperation with the New York State
Adirondack Lakes Survey Corporation and the State University of New York at
Plattsburgh. For this data layer, significant assistance was given by the Adirondack Lakes
Survey Corporation (ALSC), Ray Brook, New York. ALSC contributed most of the
scanning, which saved considerable digitizing and editing time. Also, ALSC staff
conducted the difficult task of checking wetland labels across coverage boundaries.
