Massachusetts Orthoimagery Consortium (MassOrtho) 2015

This site contains the materials and tracks the progress of the Massachusetts Orthoimagery Consortium (MassOrtho).  The following is a list of our goals:
  • To lower the cost of orthoimagery acquisition for participating communities
  • To provide a single procurement process and project management expertise at the regional level
  • To provide a basemap of regional orthoimagery that is accessible to various local, state, regional, and federal agencies 
  • To provide a predictable and sustainable model for recurring imagery procurement

  • Fact Sheet: contains cost estimatetimeline, and imagery specs.
    • Imagery spec summary
      • 7.5 cm (nominally 3 inch) resolution: which will allow for mapping of hydrants, manholes, and single trees
      • 1 foot horizontal accuracy: which will allow for the development of 2ft contours and 40-50 scale mapping
      • Leaf off imagery flown in spring 2014
      • Full color and infrared imagery
      • All the raw data / stereoimagery that will allow each participant to then contract to have planemetric data developed from it.
  • Frequently Asked Questions: many answers to common questions
  • MassOrtho is working with USGS's GPSC procurement service on process and procedures.
