Raster image of scanned USGS topological maps at 1:25,000 scale. DRG's retain most of the geometric and visual qualities of the source maps. The DRGs have been clipped by NPS to remove all text and annotations contained on the topographic sheets that are outside the map quadrangle boundary. NPS has also projected these products to Alaska Albers.The moasic was created using LizardTech MrSid software at a 20:1 compression ratio.
