National Transportation Atlas Database

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.

Sao Paulo's Spatial Data Infrastructure (Infraestrutura de dados espaciais de São Paulo)

Twelve state public agencies joined the Space Data Infrastructure Program for the State of São Paulo, IDE-SP, , whose main objective is to consolidate an integrated network of geospatial databases of government instances.The information is from Companhia Paulista de Planejamento Metropolitano (Emplasa), manager of IDE-SP, which expects to have a total of 30 accessions in the second half of 2018."IDE-SP has been showing its benefits, with the organization, systematization, standardization and dissemination, in a more agile and secure way, of geospatial information, as established by the National Spatial Data Infrastructure (INDE)", emphasizes the director-president of Emplasa, Luiz José Pedretti.He explains that since the establishment of Decree 61.486 / 2015, the SD-SP has centralized the access to geospatial data of the various public institutions, integrating the state collection and promoting the dissemination of this information. "According to article 6 of the Decree, the organs and entities of the public administration are responsible for the mandatory sharing of their geospatial data," he reinforces.Emplasa manages and is responsible for the implementation, coordination, administration and execution of the actions related to IDE-SP, which since 2017 is part of INDE. Last year, IDE-SP was a finalist for the Mario Covas Award, which highlighted public management projects for the benefit of citizens.With a new face, IDE-SP presents its new visual identity this month, developed from an exclusive brand. The platform has also been reconstructed visually, adding the same standard already used in other digital products of Emplasa.Already on the platform homepage, the user finds quick access to the metadata catalog. The viewer has been modernized and now has a smart menu that can be moved by the user. The navigation space of the maps has been enlarged, facilitating the visualization of the content.

The U.S. Wind Turbine Database & Viewer

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.

USGS TopoView

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.
