Service Description:

ORTHO_2F was collected at a 2 foot ground sample distance (GSD) , high resolution digital orthophotographs produced from aerial photos collected over southwestern, central and northeastern Maine in the Spring of 2003, 2004 and 2005. Each pixel represents a planimetric square 2 feet on a side on the ground. Aerial photography for ORTHO_2F was flown at 12,000 feet above mean ground level. Source elevation data were 10 meter Digital Elevation Models produced for this project by USGS from 1:24,000 scale elevation and hydrography data supplied by MEGIS. The digital orthorectified images (image chips) are referenced to North American Datum 1983, UTM Zone 19, expressed in units of meters. Cartographic Services for orthorectification and the creation of digital elevation models were provided by USGS Mid-Continent Mapping Center (USGSMCMC). ORTHO_2F provides a digital photographic map suitable for applications requiring a 1:4800 map scale, a National Map Accuracy Standard (NMAS) of +/- 13.33 feet. The multi-agreement program was developed and funded in coordination with the Maine GeoLibrary Board. The U.S. Department of Agriculture, Natural Resource Conservation Service (NRCS) contributed toward this project via a separate funding agreement with USGS. The completed orthorectified GeoTIFF files represent quarter-quadrangle (QQ) sized tiles with a 300m over-edge. All overedges for ORTHO_2f overlap adjacent ORTHO_1F orthophotography by this distance. ORTHO_2F tiles provide complete coverage of the TIER B boundaries as defined by the project. Tiles split by tier and project boundaries were completed to their full tile extent. Towns designated TIER B will have complete coverage by 2 foot GSD imagery.
