Free Lidar Terrain Data

MassGIS has lidar terrain and elevation data for the entire state of Massachusetts. The data can be used for for emergency response, drainage studies and hydrologic / floodplain modeling, development suitability analysis and infrastructure planning, identification of structures and other man-made features, habitat classification, vegetation mapping, and many other purposes. It was collected from 2010 to 2015.

Point and raster data derived from the original LiDAR acquisition are available for each project area:

•Point data are in ASCII text files storing XYZ coordinates, binary LAS files (zipped as LAZ), or used to create bare-earth TINs.

•Raster DEMs (digital elevation models) are GeoTiffs or Erdas IMGs.
