Improving the quality of mass produced maps Improving the quality of mass produced maps

Quality is critical in cartography because key decisions are often made based on the information the map communicates. The mass production of digital cartographic information to support geographic information science has now added a new dimension to the problem of cartographic quality, as problems once limited to small volumes can now proliferate in mass production programs. These...

All equal-area map projections are created equal, but some are more equal than others All equal-area map projections are created equal, but some are more equal than others

High-resolution regional and global raster databases are currently being generated for a variety of environmental and scientific modeling applications. The projection of these data from geographic coordinates to a plane coordinate system is subject to significant areal error. Sources of error include users selecting an inappropriate projection or incorrect parameters for a given...

Cartography at the U.S. Geological Survey: the National Mapping Division's cartographic programs, products, design, and technology Cartography at the U.S. Geological Survey: the National Mapping Division's cartographic programs, products, design, and technology

The U.S. Geological Survey (USGS) is the prime source of many kinds of topographic and special-purpose maps of the United States and its outlying areas. It is also a prime source of digital map data. One main goal of the USGS is to provide large-scale topographic map coverage of the entire United States. Most of the Nation is already covered. We expect that initial coverage will be...
