Computer software that allows geospatially referenced data to be linked to geographic features. Use this term only for information that is about GIS and not for the use of GIS in applications and projects.
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.
Methods to depict the connectedness of rock units across fault and fracture zones, allowing us to determine the distribution of geologic units, structural features, and other controlling factors, such as porosity and permeability.
Website with links to USGS hydrologic, geohydrologic, soil, and geologic projects in Missouri using geographic information systems (GIS) technology with digital datasets of images, models, and maps produced by the projects to view.
Access to downloadable GIS databases including the Global Digital Elevation Model (DEM), remotely sensed products, data on world energy and mineral deposits, biodiversity, and geologic hazards for use with ArcView or free software.
A single, consolidated point-of-entry and distribution system for USGS-hosted remotely sensed imagery and other geospatial datasets related to an event response, available through a map-based interface.
