6. Breeding Bird Atlas (2000-2005)
   Data Set Details
Depicts the distribution of breeding bird species in New York State, as recorded during the 2000-2005 Breeding Bird Atlas surveys. The Breeding Bird Atlas is a presence/absence survey. While a record of a species in a block is highly suggestive of its breeding presence there the lack of a record does not guarantee absence of the species as a breeder in the block. Atlasers were directed to work in a block until 76 species had been recorded; therefore the list of species reported breeding within a block was not intended to be comprehensive.

Matrix sites are large contiguous areas whose size and natural condition allow for the maintenance of ecological processes, viable occurrences of matrix forest communities, embedded large and small patch communities, and embedded species populations. The goal of the matrix forest selection was to identify viable examples of the dominant forest types that, if protected and allowed to regain their natural condition, would serve as critical source areas for all species requiring interior forest conditions or associated with the dominant forest types.  
28. Mined Land Permit
   Data Set Details
This data comes from the Division of Mineral Resources Mined Land Reclamation Program files and depicts point locations of most New York State Regulated mines permitted since 1975. Mines have areal extent but are represented as points, and coordinate locations are approximate. This data has not been field verified but is expected to be within 100 meters of the actual facility location. The version of the database loaded into the geographic data set has not been completely error checked. Some errors in location or attribute values may exist.The geographic data set may also contain multiple points at a single location. Mines in the database that lack coordinates or that have grossly incorrect coordinates do not appear in the geographic data set.The data should not be used for precise determination of facility buildings, property or mine entrances. DECs Division of Mineral Resources maintains a data management system on mines regulated under the Mined Land Reclamation Law (MLRL), enacted in 1975. Mines operated and closed prior to that date were not regulated or tracked by the Division. Roughly 5,400 mines are in the system, with approximately 2400 active mines and the rest reclaimed since 1975. To assist the Division in the regulation of the extractive mineral industry a database of the mines was created in the early 1980's and significantly upgraded in 2002. This is primarily a regulatory database and does not track production volumes.  
29. National Hydrography Dataset (NHD)
   Data Set Details
The National Hydrography Dataset (NHD) is a comprehensive set of digital spatial data that contains information about surface water features such as lakes, ponds, streams, rivers, springs and wells.

The data should not be used for precise determination of distances to buildings, property boundaries or other features. This is a public dataset. Wells currently afforded confidential status are plotted but confidential data is redacted. 
36. Potential Environmental Justice Areas
   Data Set Details
This is a KML/KMZ file that shows polygon locations of Potential Environmental Justice Areas. This data format can be used with a free virtual globe program, like Google Earth or ESRI's ArcGIS Explorer. Potential Environmental Justice Areas have been identified based on data from the 2000 U.S. Census. This file is derived from data originally in shapefile format. Environmental justice efforts focus on improving the environment in communities, specifically minority and low-income communities, and addressing disproportionate adverse environmental impacts that may exist in those communities. The information balloon for each census block group area displays the census block group ID, population, percent minority, percent below poverty level, county, municipality, and a link to more information on the Department of Environmental Conservation's website.

   No Login Required Data Set Details
These aquifers are those in upstate NY that consist of sand and gravel and yield large supplies of water to wells. Bedrock aquifers, although significant in some areas, are not addressed here. Source data is 1:250,000, same scale as the NYS Geological Survey surficial and bedrock geology maps on which they were based. Together these maps form a consistent set of geologic and groundwater maps for use in regional management of the groundwater resources of the State. Long Island is represented in the separate "Hydrogeologic Framework at 1:250,000 - Long Island, NY", published by USGS/NYSDEC. 
45. Upstate New York Surficial Aquifer Mapping Program (USGS)
   Data Set Details
The NYSDEC developed an implementation plan for the Brownfield and Groundwater GIS Program, and one action identified in that plan was the development of spatial datasets of the aquifer maps published by the U.S. Geological Survey Detailed Aquifer Mapping Program. The USGS has mapped over 30 sand and gravel aquifers in upstate New York at the 1:24,000-scale since the 1980's. Enhancements were made to these maps to create the digital, georeferenced map layers. The digital map layers contain original mapping units and aquifer boundaries as well as new standardized mapping units and updated aquifer boundaries. The original published aquifer maps contain additional base and geologic information not included in these map layers. See the Distribution Information section of the metadata for instructions on opening the file. 
46. US Army Corp of Engineers Historic Aerial Imagery
   Data Set Details
The New York State Department of Environmental Conservation obtained 9 inch by 9inch paper prints of panchromatic aerial photographs from the US Army Corps of Engineers for internal use and distribution to the general public. The photos cover portions of the shorelines of Lakes Erie and Ontario and the Niagara and St. Lawrence rivers. The photography was flown in 1978 and 1986 at a scale of 1:5000. DEC staff scanned the majority of the photos at 400 DPI. The remainder of the photos are planned to be scanned. The digital images were compressed to MrSID images with an average size of 5.3 MB. These images are available for download from the NYS GIS Clearinghouse ftp servers. The photos are not geo-referenced and the photo center locations are approximate. 
47. Water Inventory/Priority Waterbodies List
   No Login Required Data Set Details
Revised: November 2011
The Waterbody Inventory/Priority Waterbodies List (WI/PWL) is an inventory of the state's surface water quality. The dataset provides a summary of general water quality conditions, tracks the degree to which a water body supports its designated uses, and monitors progress toward the identification and resolution of water quality problems, pollutants, and sources. The WI/PWL reports are produced for each of the 17 major drainage basins in the state on a schedule that allows each to be updated every 5 years. The review and updating of these reports include a public participation component. The data are displayed in four themes, representing the types of water bodies included on the WI/PWL. They include Shoreline, Rivers/Streams, Lakes/Reservoirs, and Estuary.  
48. Water Quality Classifications - NYS
   No Login Required Data Set Details
Revised: November 2013
This data set provides the water quality classifications of New York State's lakes, rivers, streams and ponds, collectively referred to as water bodies. All water bodies in the state are provided a water quality classification based on existing, or expected best usage, of each water body or water body segment. Under New York State's Environmental Conservation Law (ECL), Title 5 of Article 15, certain waters of the state are protected on the basis of their classification. Streams and small water bodies located in the course of a stream that are designated as C (T) or higher (i.e., C (TS), B, or A) are collectively referred to as "protected streams."

50. Water Withdrawals - NYS
   No Login Required Data Set Details
Revised: September 2014
Data regarding water withdrawals has been collected since 1990. The reporting requirements have since been expanded. Data is currently collected in accordance with the requirements of ECL 15-1501. ECL 15-1501 requires a DEC permit and annual usage reporting for all facilities using water for any purpose and having the capacity to withdraw 100,000 gallons or more per day of surface or groundwater. These facilities may or may not be permitted with other agencies that regulate water supplies in New York State.
