These files contain scans of Topographic Reconnaissance maps of Antarctica. The source maps were published at 1:250,000-scale by the U.S. Geological Survey in cooperation with the National Science Foundation. The extent of their coverage can be seen in the “Topographic Reconnaissance Index - 250k” layer of the Atlas of Antarctic Research viewer. Use the “VIEW” link below to look at a low resolution version of the map. Then download the selected map at full resolution by clicking the download link. The metadata for each of the maps is contained in the “Full Map”download file. The maps were scanned at a ground resolution of 25.4 meters and range from 10 to 30 megabytes.They are provided in two formats: Full Map ...

The Protected Areas Database of the United States (PAD-US) is a geodatabase that illustrates and describes public land ownership, management and conservation lands nationally, including voluntarily provided privately protected areas. The lands included in PAD-US are assigned conservation measures that qualify their intent to manage lands for the preservation of biological diversity and to other natural, recreational and cultural uses; managed for these purposes through legal or other effective means. The geodatabase includes: 1) Geographic boundaries of public land ownership and voluntarily provided private conservation lands (e.g., Nature Conservancy Preserves); 2) The combination land owner, land manager, management...

Information from the USGS Flood Inundation Mapping Program: Floods are the leading cause of natural-disaster losses in the United States. More than 75 percent of declared Federal disasters are related to floods, and annual flood losses average almost $8 billion with over 90 fatalities per year. Although the amount of fatalities has declined due to improved early warning systems, economic losses have continued to rise with increased urbanization in flood-hazard areas. The USGS Flood Inundation Mapping (FIM) Program helps communities protect lives and property by providing tools and information to help them understand their local flood risks and make cost-effective mitigation decisions.
