MassGIS Base Map

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:

• 
  "Topographic Features for Basemap"  Terrain and natural features including Shaded Relief (MassGIS); States outside Massachusetts (MassGIS, USGS); Water bodies and rivers, Wetlands, Cranberry Bogs, Tidal Flats (large- and medium-scales - MassDEP and MassGIS, small-scales - USGS); Elevation Contours (large-scale - MassGIS, small-scale - USGS); Protected Open Space (Executive Office of Energy and Environmental Affairs, MassGIS)

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

• 
  "Detailed Features"
  • Political Boundaries: Massachusetts cities and towns, counties and state border (Municipalities, MassGIS)
  • Transportation: Massachusetts Department of Transportation (MassDOT) Roads (MassDOT, MassGIS); MBTA subway and Commuter Rail lines and stations (Central Transportation Planning Staff, MassGIS); Airports, Ferry Routes and Seaports (MassDOT); Airport Runways and Airfields (Massachusetts Emergency Management Agency (MEMA))
  • Infrastructure and Facilities: Lighthouses and Lights (Massachusetts Coastal Zone Management); Schools (Pre-K - High School) (Massachusetts Department of Education, MassGIS); Colleges and Universities (MassGIS); Acute Care Hospitals (Massachusetts Department of Public Health Office of Emergency Medical Services); Police Stations, Fire Stations, Town Halls (MEMA)
