<span style='overflow: auto;'><span>In
 spring 2008, the U.S. Geological Survey, as part of its Boston 133 
Cities Urban Area mapping program, contracted for true-color imagery 
covering the metropolitan Boston area and beyond. Image type for the 
entire region (more than 1.7 million acres) is 24-bit, 3-band (red, 
green, blue) natural color. Each band has pixel values ranging 0-255. 
Pixel resolution is 30 cm., or approximately one foot. In spring 2009, 
USGS continued the project and 4-band 30cm imagery was obtained for the 
remainder of the state.<br /><br />This digital orthoimagery 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. It can also serve as a reference layer or basemap for myriad 
applications inside geographic information system (GIS) software.<br /><br /></span></span><span style='overflow: auto;'><span><span style='overflow: auto;'><span>The data are served from MassGIS' ArcGIS Online account as a tiled cached map service for fast display.</span></span><br /><br />For full metadata and links to download the imagery visit <a href='http://www.mass.gov/itd/colororthos2008' target='_blank'>http://www.mass.gov/itd/colororthos2008</a>.</span></span>
