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.

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.

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...

NOTE: A newer online map viewer for the Protected Areas Database of the United States (PAD-US) is available: https://maps.usgs.gov/padusdataexplorer 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...

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.
