MassGIS Base Map

The MassGIS Base Map, available in MassMapper and many of our ArcGIS Online applications, is a general-reference map that contains a variety of features, all from the MassGIS database.

The map was designed by MassGIS staff in ESRI's ArcMap 10.x software and was cached (pre-rendered) into tile layers for the Web using ArcGIS Server 10.x. The caching process greatly speeds the display of all basemap features. A single basemap cache combines a topographic base, detailed features and 2D building structures. Each is stored in MassGIS' ArcGIS Online organizational account and is described below. Developers may refer to the REST endpoint.

In MassMapper, the full base map map actually is "constructed" with base features (terrain, natural features) that may be added from the Basemaps menu in the upper right corner of the MassMapper interface, and overlaid with three cached "tiled layers". Features and their data sources include:

The three other cached map layers, available from the "Tiled Layers" menu in MassMapper are as follows:

See the individual data layer pages (links above) for dates of each dataset.
