MassGIS Oliver

Oliver was launched in 2004 and was revamped once in 2010. MassMapper replaces Oliver with a more streamlined, user-friendly interface with speedier rendering of the interactive map.

Added new features in MassMapper include: printing directly to a PDF, and tools to draw lines and text on the map.

MassGIS Base Map

The map was designed by MassGIS staff in ESRI’s ArcMap 10.x software and was cached into tile layers for the Web using ArcGIS Server.

In MassMapper, the full base map actually is constructed with 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“.
