Spring Aerial Imagery of Northeast Minnesota:  May 2009

High-resolution orthophotography was collected for the Arrowhead Region of Minnesota in Spring 2009. Imagery details:

  • Leaf-off; four bands (red, green, blue, and near-infrared)
  • The base resolution is one-half meter (50-centimeters). With partner contributions for enhanced resolution, however, about 40% of the 15,000 square-mile project area was collected at 1-foot resolution (30 centimeters).
  • Available only via WMS (web mapping service) not download, due to large file size
