MassGIS provides geographic data and web mapping services to public and private sector users in Massachusetts using open standards. They operate a GeoServer to provide OGC Web Map Service (WMS) and Web Feature Service (WFS) endpoints. A variety of desktop and web-based clients can access and display MassGIS data through WMS/WFS requests sent to the GeoServer. MassGIS aims to improve access to their data and services over time through upgrades and performance optimizations.
