Statewide Spring Aerial Imagery Mosaic Tile Cache (2009-2014)

This tile cache web service represents a mosaic dataset that combined spring imagery conducted between 2009 and 2014 under the National Wetland Inventory (NWI) update project. All source imagery were acquired during spring, leaf-off conditions at either 1-ft or half-meter spatial resoltuion. The source imagery were also all acquired with four spectral bands (red, green, blue, or infrared). Tile cache services were created for both the true color (red-green-blue) and color-infrared (infrared-red-green) representations. The spatial extent is statewide. <br/><br/>Metadata is also available for each of the individual acquisition phases. <br/>Northeast 2009 (30cm, 50cm)<br/>East-Central 2010 (30cm, 50cm)<br/>Southern 2011 (50cm)<br/>Northwest and Central 2013-14 (30cm, 50cm)<br/><br/>The aerial imagery contractors for each phase included Keystone Aerial (northeast, Surdex (east-central & southern), and Quantum Spatial (northwest and central).<br/><br/>Funding for this data was provided by the Minnesota Natural Heritage Fund, the Minnesota Clean Water Legacy Act, and The Environmental and Natural Resources Trust Fund.<br/>
