The United States Geological Survey (USGS), a civilian Federal agency, produces several national series of topographic maps which vary in scale and extent, with some wide gaps in coverage, notably the complete absence of 1:50,000 scale topographic maps or their equivalent. The largest (both in terms of scale and quantity) and best-known topographic series is the 7.5-minute or 1:24,000 quadrangle. This scale is virtually unique to the United States and offers a convenient relation to customary units of measure where 1 map inch equals 2,000 actual feet. USGS also publishes 1:25,000 maps for metric uses, 1:100,000 maps covering 30 minutes latitude by one degree longitude, 1:250,000 covering one by two degrees, and state maps at 1:500,000 with California, Michigan and Montana needing two sheets while Texas has four. Alaska is mapped on a single sheet, at scales ranging from 1:1,584,000 to 1:12,000,000.
The Centre for Topographic Information produces topographic maps of Canada at scales of 1:50,000 and 1:250,000. They are known as the National Topographic System (NTS). A government proposal to discontinue publishing of all hardcopy or paper topographic maps in favor of digital-only mapping data was shelved in 2006 after intense public opposition.
We welcome all to our booth number 211 near AutoDesk and ESRi at this years SIGGRAPH 2015 trade show in Los Angeles. We will be demonstrating our WavGen Pro software on 4xHDPS PODs and will be streaming many of our television and large format feature film productions. We will also be demonstrating and licensing our large selection of geospatial data of the earth on planetary systems.
The SIGGRAPH conference and exhibition is a five-day interdisciplinary educational experience including a three-day commercial exhibition that attracts hundreds of exhibitors from around the world. SIGGRA..
