Problem - Since the 1980s, the U.S. Geological Survey (USGS) has mapped over 30 sand and gravel aquifers in upstate New York at the 1:24,000-scale. These mapped aquifers include both the primary and many of the principal aquifers as designated by the New York State Department of Environmental Conservation. Although the 1:24,000-scale maps are valuable in their present form, their usefulness is limited because the important features on the maps, namely aquifer boundaries and the surficial geology, are not available as digital geographic information system (GIS) datasets.
Objectives - To maximize the usefulness of the aquifer maps, GIS datasets of the 1:24,000-scale aquifer maps will be developed. To further increase applicability of the maps, consistent mapping units will be delineated and presented in relation to aquifer framework and hydrology. Aquifer information for Long Island is available from the publication HA-709, "Hydrologic framework of Long Island, New York," at 1:250,000 scale. The GIS datasets that were created for this report will be documented, reviewed and made available for release to the public. The objective is to develop consistent GIS datasets of surficial geology and aquifer boundaries from maps of selected unconsolidated aquifers in New York at the 1:24,000 scale for upstate New York and at the 1:250,000 scale for Long Island.
