The regional perspective view is enhanced further by digitally mosaicking different images collected by the same satellite to cover an even larger regional area. Another advantage is the multitemporal aspect of satellite images, which can be used to monitor changes on the Earth's surface or update an existing data set. In this particular case an existing digital AVHRR satellite image mosaic was updated with newer and better images to replace cloud covered areas, and digital image processing techniques were used to improve the presentation of the data. The United States Geological Survey's (USGS) Mini Image Processing System (MIPS) was used to apply the geometric, radiometric, and spatial filtering required to update and improve the existing digital mosaic, as well as the merging of AVHRR and topographic images. The digital image map results were published in hardcopy format as USGS Miscellaneous Investigation Series Map I-2560. The hardcopy image map scale is 1:5,000,000 with selected geographic names and contours printed on the image base. The image map was prepared by the USGS with joint support from the National Science Foundation Interagency Agreement OPP-9114787. Purpose: to create and print a continental image map of Antarctica and create an image product useful for a variety of Antarctic research areas Supplemental_Information: This data set contains 3 images: 1 rasterized DEM, and 2 bands AVHRR mosaics.

The DEM data, like the AVHRR mosaic, are in a polar stereographic projection with 1 km resolution and only simple scaling and translation were used to geometrically register the two images. The documentation supplied with the DEMs state that they were generated from contour and coastline data made available by the Antarctic Digital Database (ADD), which was produced under the guidance of the Scientific Committee on Antarctic Research (SCAR). These data were then used as input to the Australian National University Digital Elevation Model (ANUDEM) computer program developed by Michael Hutchinson. The digital image mosaic used as input was previously mosaicked, controlled, and geometrically corrected into a Polar Stereographic projection by the National Remote Sensing Center, United Kingdom. The image map was prepared by the USGS with joint support from the National Science Foundation Interagency Agreement OPP-9114787.

Details of the processing they used to generate the original mosaic can be found in the International Journal of Remote Sensing (1989, v. 10, nos. 4 and 5, p. 669-674). The USGS evaluated the geometric accuracy of the mosaic and estimated a root-mean-square error of 2.5 km. The digital image processing that created this modified image base was done at the USGS Flagstaff Field Center, Flagstaff, Arizona. Replacement images were geometrically corrected to the first image base, digitally inserted into the mosaic, and radiometrically/tone matched to blend with the surrounding images.
