This dataset contains aerial images and digital surface models of 19 out of 20 hydrological subcatchments analysed in the project "Shortcut". The subcatchments mostly lie in rural areas of the Swiss midlands and the datasets were obtained by flights with an eBee drone (SenseFly) between October 2017 and August 2018. The resolutions of the aerial images and the digital surface models lie between 2cm/pixel and 5cm/pixel, depending on the catchment. The aerial images in this dataset were used for the publication "Hydraulic Shortcuts Increase the Connectivity of Arable Land Areas to Surface Waters" (Schönenberger, U. & Stamm C, 2021)". The publication, supporting information, datasets, and codes can be found on the Eawag Research Data Institutional Repository (DOI: 10.25678/0003J3).

UPDATE: Data no longer available from this page. All non-working links have been removed (19/7/21) Users must follow instructions below from NASA to access data: SRTM data are also available globally at 1 arc second resolution (SRTMGL1.003) through the Data Pool (https://e4ftl01.cr.usgs.gov/MEASURES/SRTMGL1.003/) or from EarthExplorer where it is listed as NASA SRTM3 SRTMGL1. Please sign in with NASA Earthdata Login Credentials to download data from the NASA LP DAAC Collections. These datasets require login on both NASA Earthdata and USGS EarthExplorer systems to access data. After you create your account, you will also need to “authorize” the LP DAAC Data Pool application. On the Profile page in your Earthdata account you will need to select My Applications. On that page make sure the LP DAAC Data Pool is listed. If it isn't then select Authorize More Applications. In the dialog box type in LP DAAC Data Pool and click Search For Applications. Select Approve when presented with the lpdaac_datapool. Keep everything checked but you can uncheck the Yes, I would like to be notified box. Select Authorize and the LP DAAC Data Pool should be added to your Approved Applications.

A collection of commonly used GIS datasets for Tennessee; collections include data for Tennessee wetlands, geology, censuses, soils, digital raster graphics, and digital elevation maps. The site is currently undergoing renovations - more data will eventually become available.

From the site: "Digital elevation model (DEM) data are arrays of regularly spaced elevation values referenced horizontally either to a Universal Transverse Mercator (UTM) projection or to a geographic coordinate system. The grid cells are spaced at regular intervals along south to north profiles that are ordered from west to east. The U.S. Geological Survey (USGS) produces five primary types of elevation data: 7.5-minute DEM, 30-minute DEM, 1-degree DEM, 7.5-minute Alaska DEM, and 15-minute Alaska DEM."

The U.S. Geological Survey (USGS) National Geospatial Program is developing the 3D Elevation Program (3DEP) to respond to growing needs for high-quality topographic data and for a wide range of other three-dimensional (3D) representations of the Nation's natural and constructed features. The primary goal of 3DEP is to systematically collect 3D elevation data in the form of light detection and ranging (lidar) data over the conterminous United States, Hawaii, and the U.S. territories, with data acquired over an 8-year period. Interferometric synthetic aperture radar (ifsar) data will be acquired for Alaska, where cloud cover and remote locations preclude the use of lidar in much of the State. The 3DEP initiative is based on the results of the National Enhanced Elevation Assessment that documented more than 600 business uses across 34 Federal agencies, all 50 States, selected local government and Tribal offices, and private and nonprofit organizations. A fully funded and implemented 3DEP would provide more than $690 million annually in new benefits to government entities, the private sector, and citizens.
