资源简介：
This Northeast Alaska Hydrography data set includes digital data stream
networks digitized from U.S. Geological Survey quadrangle maps. The maps
are digitized on a Talos table with resolutions of .001'. Files are then
edited visually on a Tectronics terminal. The data is organized by 7 1/2 '
or 15 ' quads. Data are used for geographic information systems processing.
