GeoTIFFs are a high-quality raster storage format that require large amounts of disk space. JPEG2000s provide the same high-quality raster appearance, but require significantly less disk space. This second in the series details how to create seamless basemaps from USGS Topographic GeoPDF's using this more efficient file storage format.
Advancing Geospatial Solutions for Environmental Challenges
The Environmental Data Center is the center of technical expertise in GIS for the state of Rhode Island. The (EDC) is a Geographic Information System (GIS) and spatial data analysis laboratory in the University of Rhode Island's Department of Natural Resources Science, College of the Environment and Life Science. Major areas of research at the EDC are spatial data modeling, ecological mapping, and data integration for environmental applications.
The mission of the EDC is to support the use of contemporary tools of spatial data processing and electronic dissemination in the analysis and distribution of environmental data. This is achieved through collaborative research with faculty in the Department of Natural Resources Science and projects with agencies external to URI.
