Map and Image Services

Map and Image Services are a means of dynamically accessing GIS data over the Internet. This is an advanced section of the CT ECO website meant for GIS software users interested in using services from CT ECO with their own GIS software and geographic data.

Notice that most Map Services contain multiple layers. After adding the map service to your GIS, expand the group and turn on (check) the data layers.
