11 Data Sets
  Data Set Name Description
1. Digital Line Graph (DLGs)
   Data Set Details
Digital Line Graphs (DLGs) are digital vector representations of cartographic information derived from USGS maps and related sources. Depending on the scale, the following layers may be available: Public Land Survey System, Boundaries, Transportation, Hydrography, Hypsography, Non-vegetative features, Survey control and markers, Manmade features, and Vegetative surface cover. 
2. Geographic Names Information System (GNIS)
   Data Set Details
The Geographic Names Information System (GNIS), contains information for almost 2 million physical and cultural geographic features in the United States and its territories. The Federally recognized name of each feature described in the data base is identified, and references are made to a feature's location by State, county, and geographic coordinates. The GNIS is our Nation's official repository of domestic geographic names information.  
3. Geologic Map
   Data Set Details
An important resource for maps and related data concerning geology, hazards, earth resources, geophysics, geochemistry, geochronology, paleontology, and marine geology. Maps included in the Image Library are selected as a subset of the National Geologic Map Database (NGMDB). They are maps of any scale classified in the NGMDB Map Catalog as “bedrock, surficial, or general geology”. 
4. Historic National Water Conditions
   Data Set Details
The National Water Conditions are generally depicted on a streamflow map that shows generalized contour patterns of streamflow conditions for any given month on the basis of provisional data from 287 index streamflow-gaging stations. 
5. Hydrologic Units
   Data Set Details
The United States is divided and sub-divided into successively smaller hydrologic units which are classified into four levels: regions, sub-regions, accounting units, and cataloging units. The hydrologic units are arranged within each other, from the smallest (cataloging units) to the largest (regions).  
6. Long Island Hydrologic Framework
   Data Set Details
Since the 1980s, the USGS has mapped sand and gravel aquifers and confining units for Long Island, New York at the 1:250,000 scale. To maximize the usefulness of the aquifer maps, consistent mapping units were developed and delineated in relation to aquifer framework and hydrology. 
7. Mean annual runoff, precipitation, and evapotranspiration in the glaciated northeastern United States, 1951-80
   Data Set Details
The three datasets compiled at 1;1,000,000-scale, depict mean annual runoff, precipitation, and evapotranspiration in the part of the United States east of Cleveland, Ohio and north of the southern limit of glaciation. The datasets are mutually consistent in that runoff equals precipitation minus evapotranspiration everywhere. 
8. National Water Inventory System (NWIS)
   Data Set Details
The United States Geological Survey (USGS) has collected water-resources data at approximately 1.5 million sites across the United States, Puerto Rico, and Guam. The types of data collected are varied, but generally fit into the broad categories of surface water and ground water. 
9. NY StreamStats
   Data Set Details
StreamStats is a Web-based Geographic Information Systems (GIS) application that provides users with access to an assortment of analytical tools that are useful for a variety of water-resources planning and management purposes, and for engineering and design purposes. StreamStats users can select USGS data-collection station locations shown on a map and obtain previously published information for the stations. Users also can select any location along a stream and obtain the drainage-basin boundary, basin characteristics, and estimates of streamflow statistics for the location. Estimates obtained for ungaged sites assume natural flow conditions at the site. 
10. Upstate New York Surficial Aquifer Mapping Program
   Data Set Details
The USGS has mapped over 30 sand and gravel aquifers in upstate New York at the 1:24,000-scale since the 1980's. Georeferenced map layers were created for these aquifers and associated surficial geologic units.  
11. USGS Streamgages linked to the Medium Resolution NHD
   Data Set Details
The locations of approximately 23,000 current and historical U.S. Geological Survey (USGS) streamgages in the United States and Puerto Rico (with the exception of Alaska) have been snapped to the medium resolution National Hydrography Dataset (NHD). The NHD contains geospatial information about mapped surface-water features, such as streams, lakes, and reservoirs, etc., creating a hydrologic network that can be used to determine what is upstream or downstream from a point of interest on the NHD network.
