The manly map: the English construction of gender in early modern cartography The manly map: the English construction of gender in early modern cartography
Questions of gender in cartography most often focus on the sex of people involved in the cartographic process. These areas of research include the history of women cartographers (Tyner 1997: 46; Ritzlin 1989: 5; Hudson 1989: 29), the cartography of issues centered on women (Seager and Olson 1986; Seager et al. 1997; Rocheleau et al. 1995: 62), and women in the cartographic labor force...

Emergency assessment of potential debris-flow peak discharges, Coal Seam fire, Colorado Emergency assessment of potential debris-flow peak discharges, Coal Seam fire, Colorado
These maps present the results of assessments of peak discharges that can potentially be generated by debris flows issuing from the basins burned by the Coal Seam fire of June and July 2002, near Glenwood Springs, Colorado. The maps are based on a regression model for debris-flow peak discharge normalized by average storm intensity as a function of basin gradient and burned extent, and...

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...
