New 2008 Orthoimagery Planned for Eastern Massachusetts
|
In spring
2008, the U.S. Geological Survey, as part of its 133 Cities Urban Area
mapping program, has contracted for true-color imagery covering 3,000
square miles of Eastern Massachusetts. The project area (see map - PDF, 284 kb)
is roughly the area inside I-495, extending as far south as Route 44
and also includes parts of southern New Hampshire. The contractor will
use the imagery to produce orthoimages with a pixel size (or ground
surface distance) of 0.3 meters (~one foot). These images are expected
to be publicly available late in calendar 2008; MassGIS will display
and distribute this imagery via its web site. MassGIS is assisting with the project by coordinating staff resources in state agencies to assist with quality assurance work. Specifically, MassGIS has requested assistance from the Survey Section at MassHighway and from survey staff with the Department of Conservation and Recreation to assist in acquiring surveyed locations for photo-identifiable locations. Coordinates for these field locations will be used in the USGS’ quality assurance process. Also, as part of this project, MassGIS has been working to facilitate agreements between the USGS and 30 municipalities whereby the municipalities will be able to “buy-up” to higher resolution (0.15 meter or ~6” pixels) orthoimagery. MassGIS would like to thank staff at regional planning agencies and private consultants who helped with publicizing this opportunity for municipalities.  |
