Description: Spring 2021 aerial imagery for Massachusetts. The imagery is 15 cm resolution, 8-bit, 4-band (RGB-IR) data, in JPEG 2000 format. The horizontal projection/datum is NAD 1983 (2011) UTM Zones19N (meters). MassGIS converted the original GeoTiff imagery to JP2 files.Funding for this imagery was provided by MassDOT, the State 911 Department, and the Executive Office of Technology Services and Security (EOTSS).This digital orthoimagery was created to provide easily accessible geospatial data which are readily available to enhance the capability of federal, state, and local emergency responders, as well as to plan for homeland security efforts. These data also support The National Map.These images can serve a variety of purposes, from general planning to field reference for spatial analysis, to a tool for data development and revision of vector maps. The imagery can also serve as a reference layer or basemap for myriad applications inside geographic information system (GIS) software and web-based maps.
