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 ...

In order to allow for a comparison across years we visually digitized landcover of Poplar Island from a single image per year at a 1:1000 spatial extent with a minimum mapping unit of 300 square meters (no minimum dimensions aside from area). Images used to assign landcover were provided by the U.S. Army Corps of Engineers and were captured between July and October of their respective years. All images were 1 foot resolution.

This map shows conservation element summaries within areas of potential near-term and long-term energy development. These summaries help highlight areas of potential conflict between conservation elements and energy development.
This map shows potential areas with high terrestrial biodiversity from TNC Ecoregional Portfolio Core dataset.

This map shows the current distribution of major invasive vegetation species (primarily cheatgrass and tamarisk), and predicted near-term future distribution of these species. Current distribution was derived from LANDFIRE EVT v1.1, NatureServe National Landcover v2.7, Early Season Invasives (USGS), Predicted Tamarisk Probability (USGS), and mapped areas of tamarisk. Predicted future distribution included these areas in addition to the invasive vegetation class from the LANDFIRE Succession Class v1.0 dataset.

This map shows the potential current distribution of white-tailed prairie dog, in the context of current and near-term terrestrial intactness and long-term potential for climate change and energy development.

This map shows areas of high current, near-term, and long-term potential landscape development, based on factors such as urban areas, agriculture, roads, and energy development.

This map shows the major terrestrial ecosystems from LANDFIRE EVT (v1.1) and NatureServe National Landcover (v2.7).

PAD-US: America's Inventory of Protected Areas and Parks​ The Protected Areas Database of the United States (PAD-US) assembles known protected areas that prioritize biodiversity conservation, and also assembles lands and waters that provide public access to nature. PAD-US is a single, regularly updated geospatial database that allows users to find exact boundaries and essential attribute information for protected areas in the United States. The PAD-US is an authoritative data aggregation, with source data provided by the Data Stewards network that includes public lands managed by agencies, preserves owned by nonprofits, and private lands protected via conservation easement in the United States. It serves many types...

This raster depicts the percentage of lithological the hydraulic conductivity (in micrometers per second) of surface or near surface geology. We derived these rasters by calculating the average conductivity for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272), which depict surficial geology instead of bedrock when the surficial layers are sufficiently deep. For the state maps that do not incorporate surficial geology (i.e., midwestern states), we overlaid surficial geologic map units with thicknesses greater...
