New 2010 Imagery Available
By Nancy Rader, MnGeo
Two new resources have been added to Minnesota’s growing catalog of orthoimagery. Summer imagery from the Farm Service Agency covers the entire state, and spring imagery covers 11 counties in the Twin Cities metro area.
2010 FSA Orthophotos
This summer leaf-on imagery, collected by FSA as part of its National Agriculture Imagery Program, is provided at 1-meter resolution. Four bands were collected; currently, only the natural color (3-band) imagery is available. Users can view the images via MnGeo’s WMS service or MnGeo’s NorthStar Mapper application, or download them as compressed county files in MrSID format. A seamline shapefile identifies the actual area of each photo used in the orthoimagery and documents the date the photo was flown.
For more information and viewing/download options, see the NAIP10 webpage.
2010 Metro Imagery
A multi-year project to collect high-resolution, leaf-off, 4-band imagery for the whole state is currently in progress. During the spring of 2009, orthoimagery was collected for the Arrowhead and this spring the Twin Cities Metro was flown. The imagery is being obtained to support the Minnesota Department of Natural Resources’ phased update of the National Wetland Inventory.
Eleven counties were flown this year: Anoka, Carver, Chisago, Dakota, Hennepin, Isanti, Ramsey, Scott, Sherburne, Washington and Wright. Resolution varies between 12-inches and 20-inches depending on the county. The imagery can be viewed via MnGeo’s WMS service. For more information, see the East-Central Minnesota webpage.
Next year’s phase includes 36 southern counties. Major funding for the project is provided through the Environmental and Natural Resources Trust Fund. Additional partners are helping to fund specific areas of the state. For more details, see the project webpage.
