Socioeconomic Data and Applications Center (SEDAC)

About:	NASA's Socioeconomic Data and Applications Center (SEDAC), based at CIESIN, has gridded nearly 12,000 species distribution maps which were originally in vector format (ESRI shapefile). The original data were developed by a consortium of conservation organizations including NatureServe, IUCN, Conservation International, and World Wildlife Fund-USA. To make these data more useful for modeling and for integration with socioeconomic and other data, SEDAC converted the entire collection of shapefiles to raster format. This newly released Web site provides a search facility for quickly locating and downloading 1-kilometer (30 arc-second) resolution grids of selected species maps in GeoTIFF format. Data are available for global amphibian distributions, and for birds and mammals in the Americas. The Web site provides access to individual species distribution grids, along with family grids that show the density and distribution of species within a given family.

This team, known as the Southeast Florida Coral Reef Initiative Team (SEFCRI Team), first gathered in May 2003 to develop local action strategies targeting coral reefs and associated reef resources from Miami-Dade County, through Broward, Palm Beach and Martin Counties, to improve the coordination of technical and financial support for the conservation and management of coral reefs. The Southeast Florida Coral Reef Initiative (SEFCRI) is targeting this region because the coral habitats are close to shore and co-exist with intensely urbanized areas that lack a coordinated management plan (like that of the Florida Keys National Marine Sanctuary).

About:

Temporal urban mapping develops a historical perspective of urban development by combining a variety of data sources into an integrated, multi-scale, and multi-resolution database. The database provides the baseline information to model and predict regional patterns of urbanization. Temporal urban mapping relies on modern mapping techniques, such as remote sensing and geographic information systems (GIS), to capture information from both historical and modern records.

Urban Dynamics

About:	The Urban Dynamics project analyzes land use change in urban environments in order to provide a historical perspective of land use change and an assessment of the spatial patterns, rates, correlation, trends, and impacts of that change. This project develops and refines methods for land use reconstruction, geographic analysis, modeling, prediction, monitoring, and impacts assessment.

Socioeconomic Data and Applications Center (SEDAC)

About:	NASA's Socioeconomic Data and Applications Center (SEDAC), based at CIESIN, has gridded nearly 12,000 species distribution maps which were originally in vector format (ESRI shapefile). The original data were developed by a consortium of conservation organizations including NatureServe, IUCN, Conservation International, and World Wildlife Fund-USA. To make these data more useful for modeling and for integration with socioeconomic and other data, SEDAC converted the entire collection of shapefiles to raster format. This newly released Web site provides a search facility for quickly locating and downloading 1-kilometer (30 arc-second) resolution grids of selected species maps in GeoTIFF format. Data are available for global amphibian distributions, and for birds and mammals in the Americas. The Web site provides access to individual species distribution grids, along with family grids that show the density and distribution of species within a given family.

About:	The LCMGB recorded 25 land cover types, on a 25 m grid, for all of Britain. The generalised census, as a part of the Countryside Survey 1990, complemented the sample-based detail of the field survey. The LCMGB and the field data were compared and contrasted qualitatively and quantitatively, giving correspondences which varied from 50%-90% and suggested that the map accuracy was generally 80%-85% - an exact quantification was precluded by crucial differences in the dates of survey and the choices of class definitions. The LCMGB data give complete, though generalised, national coverage and are uniquely capable of generating useful information at a field-by-field level.
