Maps of areas greater than 0.2 hectare (0.5 acre) dominated by invasive Phragmites australis were created for the coastal region (shoreline to 10 km inland) of the United States side the Great Lakes and connecting water ways. The maps were developed using unsupervised/supervised classification methods and ground truth data collected during 2010 and 2011 in conjunction with multi-season ALOS PALSAR imagery (for the remote sensing-based iterative classification process), as well as through the interpretation of aerial photography to reduce classification confusion. Overall classification accuracy compared to field data for mapping was approximately 86%.

From the WaterAlert about text: The U.S. Geological Survey WaterAlert service sends e-mail or text (SMS) messages when certain parameters, as measured by a USGS real-time data-collection station, exceed user-definable thresholds. The development and maintenance of the WaterAlert system is supported by the USGS and its partners, including numerous federal, state, and local agencies. Real-time data from USGS gages are transmitted via satellite or other telemetry to USGS offices at various intervals; in most cases, once every hour. Emergency transmissions, such as during floods, may be more frequent. Notifications will be based on the data received at these site-dependent intervals.

This collection (known internally to Maryland Geological Survey as Component 4) consists of 375 22-inch by 34-inch photo-mosaic index maps dating from 1936-1980. These index maps depict flight lines and frame numbers for two components of the MGS Aerial Photograph Collection: 1) Component 1: County-Based Aerial Photographs (https://www.sciencebase.gov/catalog/item/4f4e4a94e4b07f02db658dba); and 2) Component 2: MD Barrier Island Aerial Photographs (Enlargements) (https://www.sciencebase.gov/catalog/item/4f4e4aafe4b07f02db66cf18). These index maps serve as a finding aid for these two components. All of the index maps have been scanned (most to JPG, PDF, and TIF format). Digital imagery (PDF) for the majority...

This map depicts the geology of the Huachuca City 7.5' quadrangle in Cochise County, southeastern Arizona, which consists almost entirely of upper Cenozoic surficial deposits. The map area is located between Benson and Sierra Vista along the western side of the upper San Pedro River Valley. The map area covers much of the southeastern piedmont of the Mustang and Whetstone mountains, part of the valley of the Babocomari River, and part of the northern piedmont of the Huachuca Mountains. It includes the small communities of Huachuca City and Whetstone, and the northern fringe of Fort Huachuca, a U.S. Army base. The quadrangle is roughly bisected by State Route 92, a major four-lane highway connecting the Sierra Vista...

The National Biogeographic Map is a web-based application designed to bring together USGS biogeographic data and information for analysis and synthesis. Some of the software and data found in the National Biogeographic Map is considered provisional and subject to revision until it has been fully vetted through the USGS release process. They are provided here to meet the need for timely best science.
NOTE: A more current version of the Protected Areas Database of the United States (PAD-US) is available: PAD-US 2.1 https://doi.org/10.5066/P92QM3NT. The USGS Protected Areas Database of the United States (PAD-US) is the nation's inventory of protected areas, including public land and voluntarily provided private protected areas, identified as an A-16 National Geospatial Data Asset in the Cadastre Theme (https://communities.geoplatform.gov/ngda-cadastre/). The PAD-US is an ongoing project with several published versions of a spatial database including areas dedicated to the preservation of biological diversity, and other natural (including extraction), recreational, or cultural uses, managed for these purposes...
