Map Services

Web Map Services

Map services offer access to GIS features and attributes by allowing you to view, identify, find, and query datasets within your preferred mapping application such as ArcGIS Desktop. The URL for a map service cannot be viewed in a web browser because it is a web service that broadcasts data over the internet in a format that can only be interpreted by a supporting map application. When you use NDEP's map service you are working with the most current GIS datasets available, as many bureau specific datasets are updated every day. The "eMap" Map Service contains the same datasets as the eMap online map. A high-speed internet connection is required for best performance. Please see the following instructions on how to connect to NDEP's map services using a mapping application.
