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.

Scroll down the list of aerial imagery and elevation.

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.

      This is a Connecticut town layer with an attribute for area and percent of each land cover class including change. The layers in the service (Forest, Forest Change, Ag. Field, Ag. Field Change, Developed, Developed Change, Turf and Grass, Turf and Grass Change) have been symboloized using the appropriate attribute. The Town Stats layer is an outline and includes all attributes. In the attributes, "a" stands for "acres," "p" stands for percent, the year is either 1985, 2015, or 1985-2015 change "8515." Class numbers are listed on the classes page. For example, the attribute a1985_1 is acres in 1985 of class 1, developed.
