Orthoimagery

Modis

Orthoimagery is an aerial image geometrically corrected so that the scale is uniform, giving the image the same lack of distortion as a map.

GINA has a large archive of Orthoimagery from a wide variety of sources. Users can view and download scenes from the archive through the Statewide Digital Mapping Initiative’s (SDMI) Browse Site or by using the SwathViewer .

GINA’s Best Data Layer is a collection of Aerial and Satellite based orthoimagery provided as a Web Mapping Service for desktop GIS clients like ESRI’s ArcMap or Quantum GIS . Details on how to use the BDL WMS can be found here.

The Best Data Layer is also available as a tile service for use in various web mapping frameworks. Information on how to use the tile services can be found in the support document website.
