About DEC Data

DEC collects a large amount of data while carrying out its mission of protecting human health and the environment. Monitoring, permitting, and inspection records, wildlife and habitat data, and other forms of information are entered into databases which are used by DEC employees to make better environmental decisions. Some databases contain information which changes frequently and for which timeliness is important. When possible, these will be made available online through a database search so that the public who use this information to make personal or professional decisions will have the best information available.

DECinfo Locator

DECinfo Locator is an interactive map that lets you search for a location and access many DEC documents and other public data about the environmental quality of specific sites in New York State, as well as information about sites for outdoor recreation. It contains more than 50 data layers; see our layer description web page to see what is available and how often it is updated.

Open NY Program

As part of the Open NY program, the New York State Office of Information Technology Services (OITS) created an open data website ( It contains more than 1300 NYS data resources on topics ranging from solar photovoltaic projects to locations of farmers markets. The data is standardized, machine-readable and freely available. There are more than 103 DEC datasets available on for users to analyze and use so if you do not see what you need below, please visit the statewide open data website.
