PDF A New Method for Mapping Population Distribution [More info]
With the addition of elevation and land use and land cover data, we can show population density on a map much more effectively than if we simply color census areas. The resulting maps should allow better planning, especially in highly developed areas.
A program for the conversion of The National Map data from proprietary format to resource description framework (RDF) [More info]
To expand data functionality and capabilities for users of The National Map of the U.S. Geological Survey, data sets for six watersheds and three urban areas were converted from the Best Practices vector data model formats to Semantic Web data formats.
