Minnesota. Department of Natural ResourcesThis 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. Metadata is also available for each of the individual acquisition phases. Northeast 2009 (30cm, 50cm) East-Central 2010 (30cm, 50cm) Southern 2011 (50cm) Northwest and Central 2013-14 (30cm, 50cm) The aerial imagery contractors for each phase included Keystone Aerial (northeast, Surdex (east-central & southern), and Quantum Spatial (northwest and central). 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. Support multi-agency efforts including wetland mapping, urban planning, forest management, soil mapping, and utility siting.Acquisition period for aerial imagery: 2009-2014Filesbase-saip-2009-2014engPublicStatewide Spring Aerial Imagery Mosaic Tile Cache (2009-2014) [Minnesota]ImageryMinnesotaMinnesota Geospatial Commons
