8. Recent Developments FSA will allow early flights over six northeastern counties – Cook, Lake, St. Louis, Carlton, Koochiching and Itasca – in hopes of collecting leaf-off imagery. Weather conditions will largely dictate how successful this effort will be. In addition to providing leaf-off orthoimagery for the Arrowhead, SURDEX is considering flying the region at a lower elevation to produce two-foot resolution orthoimagery, in addition to the federally-contracted one-meter product. Incremental cost of providing the higher resolution product is about $15.00 per square mile. If you think your county or municipality might be interested in partnering in this higher resolution buy-up, or if you have questions about the project, please contact Minnesotas NAIP state liaison, Chris Cialek, as soon as possible.
