GIS Data Dictionary

We are in the process of creating an all new Cambridge GIS Data Dictionary. These pages are about a year old, but do not include data from our new April 14, 2010 flyover. Please keep checking back for updates.

The GIS Database Dictionary is an online guide for our GIS user community. Each page has detailed information on the individual GIS data layers that are stored on the City of Cambridge GIS system.

The dictionary contains information on how and why a GIS layer was created, coding of attributes, our procedure for maintaining each layer, departments which contribute to the development of each layer, history, and the intended use of the data.
