Denali image map

The Denali National Park and Preserve 1:250,000-scale image map has been prepared and published as part of the US Geological Survey's (USGS) continuing research to improve image mapping techniques. Nine multispectral scanner (MSS) images were geometrically corrected, digitally mosaicked, and enhanced at the National Mapping Division's (NMD) EROS Data Center (EDC). This process involves ground control and digital resampling to the Universal Tranverse Mercator (UTM) projection. This paper specifically discusses the preparation of the digital mosaic and the production peculiarities associated with the Denali National Park and Preserve image map.
