1000' Contours
The Alaska Department of Natural Resources (ADNR) has combined hypsography for several Digital Chart of the World (DCW) tiles into one coverage.  Some edits to the data were made, which allowed ADNR to label high elevation points and mountain tops from the DCW data.  The coverage contains elevation contours at every 1,000 feet. The hypsography used for statewide map products is often depicted as a contour line at every 3,000 feet, which offers visualization of vertical control as it relates to the other map features.

The hypsography data were combined from the HYPOINT and HYNET coverages comprising the following 5 degree by 5 degree tiles for Alaska: AK 12,22,23,32,33; AL 21,31,32; BK 12,13,22,23,33; BL 11,12,13,21,22,23,31,32,33; CK 12,23,33; CL 11,12,13,21,22,23,31; DK 12,13,22,23; and ZK 22,32.
