Elevation from Lidar (2013 to 2021) (Image Service)

Digital Elevation Model from Lidar (2013-2021), with values in meters and feet. Image service published by MassGIS from ArcGIS Server. The DEM was created from Light Detection and Ranging (Lidar) terrain and elevation data that cover the entirety of Massachusetts. This DEM is based on the best available lidar data, as described at the Lidar Terrain Data page. The DEM is a 16-bit signed integer raster dataset and has a 0.5 meter pixel resolution. This image service is the source for the values appearing in the popup in the Massachusetts Elevation Finder application.
