Coastal Vulnerability to Sea-Level Rise : A Preliminary Database for the U.S. Atlantic, Pacific and Gulf of Mexico Coasts The goal of this project is to quantify the relative susceptibility of the Nation's coast to sea- level rise through the use of a coastal vulnerability index (CVI). The combination of these variables (coastal geomorphology, regional coastal slope, tidal range, wave height, historical rates of relative sea-level rise and shoreline erosion and accretion rates) furnishes a broad overview of regions where physical changes are likely to occur due to sea-level rise.

SAT 10 Maine - Delorme SAT 10 is 10-meter resolution natural color satellite imagery for the entire state of Maine derived from merging SPOT 10m panchromatic and Landsat 30m multi-spectral scenes, tonal balanced and edge-matched to create a mosaic image across the state. Geo-registered using ground control points from the USGS 7.5-minute topo maps and ortho-corrected using USGS Digital Elevation Model (DEM). Most of the scenes used were taken in 2000 and 2001 with no scenes older than 1998. Use in conjunction with TOPO USA allows for split scene capability, where you can view the satellite imagery on one side and the 3-D TopoQuads data on the other. Click image for more information. |

GIS in Times of Disaster Geographic Information Systems play a very important role during three critical stages of a disaster: Emergency Preparedness; Damage Assessment; and Relief & Recovery Efforts. Agencies can combine data from many sources and present them spatially to assess the situation and coordinate efforts. Geodata.gov has a good collection of information that show how GIS helps make sense out of chaos here. Click image for more information. |

NASA's Landsat Thematic Mapper Mosaic page allows online viewing and downloading (in mrsid format) of 30 meter Landsat false color satellite images. These images cover most of the land-covered portion of the earth and are georeferenced for use in GIS. Click image for more information. |

GeoBase
is a federal, provincial and territorial
government initiative that is overseen by the Canadian
Council on Geomatics (CCOG) with generous contributions form the
GeoConnections.
This portal, from Natural Resources Canada, provides free
access to quality, up-to-date geospatial data including administrative
boundaries, digital elevation data, geographical names, Landsat-7
imagery, and the national road network for all of Canada. |

SEA-GEOFISH
The
Southeast Geographic Fishery-Independent Survey and Historical (SEA-GEOFISH)
Database is a Web-based mapping application that provides access to
more than 30 years worth of data
from a long-term fishery survey conducted by the
South Carolina Department of Natural Resources (SCDNR). The maps
include distribution
of fish species; data on abundance, biomass, diversity and spawning,
plus GIS-based statistical analysis tools. |
