ESRI and the National Geographic Society have announced the immediate availability of National Geographic’s award-winning TOPO! Software, which combines seamless map coverage of most U.S. states with easy-to-use mapping tools. Also available through ESRI is National Geographic’s TOPO! Extension for ArcGIS, which allows users of ESRI’s flagship ArcGIS product line to use data contained in the TOPO! products for geographic information system (GIS) applications.
TOPO! products cover an entire state or group of states. Each product includes statewide coverage from scanned United States Geological Survey (USGS) 1:24,000- and 1:100,000-scale topographic maps and is global positioning system (GPS)-ready. TOPO! products can be used to create routes and upload waypoints to a GPS. In addition, three-dimensional digital shaded relief can be toggled on/off.
TOPO! products are currently available for Arizona, Arkansas, California, Colorado, Florida, Georgia, Idaho, Illinois, Indiana, Michigan, the mid-Atlantic states (Delaware, Maryland, Virginia, and West Virginia as well as the District of Columbia), Minnesota, Missouri, Montana, Nebraska, Nevada, New Mexico, North Carolina, the northeastern states (Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Vermont), Ohio, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Washington, Wisconsin, and Wyoming. Other states will be available soon. TOPO! products are priced at $99.95 each.
National Geographic’s TOPO! extension for ArcGIS lets users import TOPO! state series
basemap data directly into their ArcGIS project. The extension compiles the scanned map data and quickly imports a seamless map into ArcGIS that exactly matches the project coverage area. During this process, the basemap is copied to a hard drive and conveniently stored as a single layer or theme. The extension supports a broad range of projections and is compatible with ArcGIS 8.1 and ArcView 3.x.
You can purchase National Geographic TOPO! data sets and the TOPO! extension for ArcGIS from ESRI’s online GIS store
