NEW Vermont Orthos Available for Rutland & Windsor Counties!

Leslie Pelch, VCGI

The first installment of the THIRD vintage of digital orthophotos of Vermont is available for free download!

Covering roughly Rutland and Windsor counties, the new imagery has the following characteristics:

  •  .5 meter pixels (same as Orthophotography collected by VT Mapping Program until 2009)
  • A set of color images with near infra-red included (CLRIR) and a set of black and white images ( PAN) will be available (previously only black and white was available)
  • Accuracy is expressed as follows: The horizontal accuracy of the orthorectified imagery shall meet or exceed a verified ASPRS Class I horizontal accuracy of +/- 1 meter RMSE (for both X and Y) for 50cm ground sample distance imagery and 2.44 meters at 95% confidence level according to the NSSDA standard methodology.

The VT Imagery Program “News” page has links to an FAQ about the imagery as well as where to download:
