How well are we protecting common plants and animals? Gap Analysis is the science of answering this question. Developing the data and tools to support that science is the mission of the USGS Gap Analysis Program (GAP). GAP works to ensure that common species – those that are not officially endangered – remain common by identifying those species and plant communities that are not adequately represented in existing conservation lands. Learn more about Gap Analysis >>They work with a wide range of government, academic, non-profit and private partners, providing them with essential data and analyses that they can use to protect the habitats on which the survival of common species depends.
The National Transportation Atlas Database (NTAD), published by BTS, is a set of nationwide geographic databases of transportation facilities, transportation networks, and associated infrastructure. These datasets include spatial information for transportation modal networks and intermodal terminals, as well as the related attribute information for these features. There are approximately three dozen point, line and polygon “data themes,” comprising of about 60 total datasets that make up the NTAD. Metadata documentation, as prescribed by the Federal Geographic Data Committee (FGDC), is also provided for each database. These data support research, analysis, and decision-making across all modes of transportation. They are most useful at the national level, but have major applications at regional, state, and local scales throughout the transportation community. The current NTAD databases are designed for use within a geographic information system (GIS); however, the attribute data for each dataset can be accessed in any database, spreadsheet, or other software package. In 2016, NTAD switched from an annual update to updates on a continuous basis. The BTS is interested in providing different distribution approaches and developing additional datasets.
Data themes are available in three levels of detail. For each scale, themes are listed on Cultural, Physical, and Raster category pages.

Open Data Inception - 2600+ Open Data Portals Around the WorldFrom their website:When building the best Open Data portals, the same question always comes up:Where can I find clean and usable data?Our answer is usually: “Did you search on existing Open Data portals?”But the truth is, some Open Data portals can be hard to come by.We decided to put together a resource that would be truly useful for all the data geeks out there (and we know we are plenty ). We called this project: Open Data Inception.We rolled up our sleeves and started aggregating all of the Open Data portals we could get our hands on. We are thrilled to present you the first version of our comprehensive list of 2600+ Open Data portals around the world.To facilitate your search, we decided to geotag intergovernmental organization portals on their parent organization headquarters.The table of contents will give you a summary of all countries represented on this list. Simply click on a country’s name and the page will bring you to the correct section.If you are curious about how we created this list, we wrote an article about it.We hope that you will find solace in your data quest with this list. Don’t hesitate to send us feedback through the form at the bottom of the page or at @opendatasoft.

Imagery and elevation data are the most important and frequently used Framework data, however, they also require expansive amounts of disk storage space. The Oregon Imagery Explorer enables users to view, compare, stream, and download National Agriculture Imagery Program (NAIP) Orthoimagery from multiple epochs since 1995. In addition to the Imagery Explorer Application, the same imagery can be accessed through web services in your web or desktop client of choice, allowing you to access the data without having to download and store it. For more information on the imagery web services, click here. The Imagery Framework is helping realize the vision of navigatOR with state-of-the-art accessibility to common data themes that geographic data users need.You might also be interested in https://www.oregon.gov/geo/Pages/imagery.aspx.

The United States Wind Turbine Database (USWTDB) provides the locations of land-based and offshore wind turbines in the United States, corresponding wind project information, and turbine technical specifications. The creation of this database was jointly funded by the U.S. Department of Energy (DOE) Wind Energy Technologies Office (WETO) via the Lawrence Berkeley National Laboratory (LBNL) Electricity Markets and Policy Group, the U.S. Geological Survey (USGS) Energy Resources Program , and the American Wind Energy Association (AWEA). The database is being continuously updated through collaboration among LBNL, USGS, and AWEA. Wind turbine records are collected and compiled from various public and private sources, digitized or position-verified from aerial imagery, and quality checked. Technical specifications for turbines are obtained directly from project developers and turbine manufacturers, or they are based on data obtained from public sources.

TopoView highlights one of the USGS's most important and useful products, the topographic map. In 1879, the USGS began to map the Nation's topography. This mapping was done at different levels of detail, in order to support various land use and other purposes. As the years passed, the USGS produced new map versions of each area. The most current maps are available from The National Map. TopoView shows the many and varied older maps of each area, and so is useful for historical purposes—for example, the names of some natural and cultural features have changed over time, and the 'old' names can be found on these historical topographic maps.This interface was created by the National Geologic Map Database project (NGMDB), in support of topographic mapping program managed by the National Geospatial Program (NGP). Geologic mapping and topographic mapping at the USGS have a long tradition together (see 1888 report). The NGMDB project is proud to assist the NGP in bringing these maps to the Web.
