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.
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.

Fact sheet describing the value of The National Map designed as a network of digital databases that will provide a consistent national geographic data framework in responding to natural hazards and human-induced disasters.
Complex geographic information can be analyzed with mathematical models to show us the spatial patterns of human building, vegetation growth, and other landscape characteristics that may result from environmental changes we may expect in the future.
Quantifies the landscape changes and consequences of natural gas extraction by digitizing indications of disturbance on NAIP aerial photographs and using these with the NLCD to show land use-land cover change.
