Aerial Detection Survey: Quad Maps
Aerial survey missions in Region 2 are flown each year from roughly the Fourth of July through Labor Day. Quad maps are produced to provide land and resource managers with a rough idea of current insect and disease activity.
The GIS files for the season's aerial survey, which takes a bit more processing, usually become available for download in the winter.
