Service Description: Medium resolution true color ortho images for the Commonwealth of Massachusetts, distributed by MassGIS. The photography for the entire commonwealth was captured in April 2005 when deciduous trees were mostly bare and the ground was generally free of snow. Original imagery pixel resolution is 1/2-meter.

Original image type is 4-band (RGBN) natural color (Red, Green, Blue) and Near infrared in 8 bits (values ranging 0-255) per band format. This map service contains only the RGB bands and uses the "contrast stretched" JPEG 2000 versions MassGIS Produced from the original GeoTiff files. Image horizontal accuracy is +/-3 meters at the 95% confidence level at the nominal scale of 1:5,000. This digital orthoimagery can serve a variety of purposes, from general planning, to field reference for spatial analysis, to a tool for development and revision of vector maps. It can also serve as a reference layer or basemap for myriad applications inside geographic information system (GIS) software. The project was funded by the Executive Office of Environmental Affairs, the Department of Environmental Protection, the Massachusetts Highway Department, and the Department of Public Health.

This imagery is served as a tiled cached map service from MassGIS' ArcGIS Online account for fast display.
