MassGIS has many map layers (roads, wetlands, aerial photos, property parcels, etc) that can be combined to make a map for any area in the state using the Oliver interactive mapping tool. Other interactive, pre-made maps focus on a common theme such as Legislative Districts, Shoreline Change, Dams and many more topics. We also offer a host of ready-made maps and web services at ArcGIS Online. Also check out the additional resources section for maps from other state agencies.
