SRTM Shaded Relief Anaglyph of Zagros Mountains. The SRTM was flown on an 11-day mission of the Space Shuttle Endeavour in February 2000. [1] This NASA image used Landsat data to texture-map the surface created using SRTM Elevation data. The Cape Peninsula and Cape of Good Hope, South Africa, are visible in the foreground.
As of 2 April 2016, the entire catalogue of ASTER image data became publicly available online at no cost. [4] It can be downloaded with a free registered account from either NASA's Earth Data Search delivery system [5] or from the USGS Earth Explorer delivery system. [6]
Demo map showing high-resolution SWBD coastlines. The SRTM Water Body Data (SWBD) is a geographical dataset (2003) encoding high-resolution worldwide coastline outlines in a vector format, published by NASA and designed for use in geographic information systems and mapping applications.
Climate web viewer containing accessible climatic information from 1901 that can be downloaded in a variety of GIS formats. HydroSHEDS: Global hydrological data based on the SRTM elevation data. Includes river networks, watershed boundaries, drainage directions, and flow accumulations. USGS Land Cover Institute
Most of the data providers (USGS, ERSDAC, CGIAR, Spot Image) use the term DEM as a generic term for DSMs and DTMs. Some datasets such as SRTM or the ASTER GDEM are originally DSMs, although in forested areas, SRTM reaches into the tree canopy giving readings somewhere between a DSM and a DTM). DTMs are created from high resolution DSM datasets ...
The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website.
NASA Shuttle Radar Topography Mission (SRTM) Digital Elevation Model (DEM): These are bitmap files released into the public domain, compressed into zip file format, which contain the digital topographic data of a given region. The zone covered by the DEMs resulting from the SRTM runs from latitude 56° South to latitude 60° North. These files ...
STS-99 was a Space Shuttle mission using Endeavour, that launched on 11 February 2000 from Kennedy Space Center, Florida.The primary objective of the mission was the Shuttle Radar Topography Mission (SRTM) project.
