Global Multi-Resolution Topography Data Portal

GMRT

Subject(s)
Content type(s)
Country
The Global Multi-Resolution Topography (GMRT) Synthesis is a dynamically maintained global multi-resolution synthesis of terrestrial and seafloor elevation data available as images & gridded data values.

TanDEM-X ISDC

Subject(s)
Content type(s)
Country
TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) is the first bistatic SAR mission in space. TanDEM-X and its twin satellite TerraSAR-X are flying in a closely controlled formation with typical distances between 250 and 500 meters. Primary mission objective is the generation of a consistent global digital elevation model with few meter level height accuracy. Beyond that, GFZ equipped TanDEM-X with a geodetic grade GPS receiver for precise baseline determination and for radio occultation measurements. TanDEM-X was launched on June 21, 2010 for a 5 year mission lifetime. The GPS radio occultation data of the German TanDEM-X satellite are analysed and globally distributed vertical atmospheric profiles (bending angles, refractivity, temperature, water vapor) are derived and provided for the international user community.

ASTER Volcano Archive

AVA

Subject(s)
Content type(s)
Country
The ASTER Volcano Archive (AVA) is the worlds largest specialty archive of volcano data. For 1,549 recently active volcanos listed by the Smithsonian Global Volcanism Program, the AVA has collected the entirety of high-resolution multispectral ASTER data and made it available to the public. Also included are digital elevation maps, NOAA ash advisories, alteration zone imagery, and thermal anomaly reports. LANDSAT7 data are also being processed.

Shuttle Radar Topography Mission

SRTM

Subject(s)
Content type(s)
Country
The Shuttle Radar Topography Mission, which flew aboard NASA's Space Shuttle Endeavour during an 11-day mission in 2000, made the first near-global topographical map of Earth, collecting data on nearly 80 percent of Earth's land surfaces. The instrument's design was essentially a modified version of the earlier Shuttle Imaging Radar instruments with a second antenna added to allow for topographic mapping using a technique similar to stereo photography.

GEON

GEONGRID

Subject(s)
Content type(s)
Country
-----<<<<< The repository is no longer available. This record is out-dated. >>>>>----- GEON is an open collaborative project that is developing cyberinfrastructure for integration of 3 and 4 dimensional earth science data. GEON will develop services for data integration and model integration, and associated model execution and visualization. Mid-Atlantic test bed will focus on tectonothermal, paleogeographic, and biotic history from the late-Proterozoicto mid-Paleozoic. Rockies test bed will focus on integration of data with dynamic models, to better understand deformation history. GEON will develop the most comprehensive regional datasets in test bed areas.

AusGeochem

Subject(s)
Content type(s)
Country
AusGeochem is an easy-to-use platform for uploading, visualising, analysing and discovering georeferenced sample information and data produced by various geoscience research institutions such as universities, geological survey agencies and museums. With respect to analytical research laboratories, AusGeochem provides a centralised repository allowing laboratories to upload, archive, disseminate and publish their datasets. The intuitive user interface (UI) allows users to access national publicly funded data quickly through the ability to view an area of interest, synthesise a variety of geochemical data in real-time, and extract the required data, gaining novel scientific insights through multi-method data collation. Lithodat Pty Ltd has integrated built-in data synthesis functions into the platform, such as cumulative age histograms, age vs elevation plots, and step-heating diagrams, allowing for rapid inter-study comparisons. Data can be extracted in multiple formats for re-use in a variety of software systems, allowing for the integration of regional datasets into machine learning and AI systems.

OpenTopography

A Portal to High-Resolution Topography Data and Tools

Subject(s)
Content type(s)
Country
OpenTopography facilitates community access to high-resolution, Earth science-oriented, topography data, and related tools and resources. The OpenTopography Facility is based at the San Diego Supercomputer Center at the University of California, San Diego and is operated in collaboration with colleagues in the School of Earth and Space Exploration at Arizona State University and Earthscope Consortium. Core operational support for OpenTopography comes from the National Science Foundation Earth Sciences.

Advanced Spaceborne Thermal Emission and Reflection Radiometer Ground Data Systems

Subject(s)
Content type(s)
Country
!!! We will terminate ASTER Products Distribution Service in March 2016 although we have been providing ASTER Products since November 20, 2000. !!! ASTER (Advanced Spaceborne Thermal Emission and Reflection radiometer) is the high efficiency optical imager which covers a wide spectral region from the visible to the thermal infra-red by 14 spectral bands. ASTER acquires data which can be used in various fields in earth science. ASTER was launched from Vandenberg Air Force Base in California, USA in 1999 aboard the Terra, which is the first satellite of the EOS Project. The purpose of ASTER project is to make contributions to extend the understanding of local and regional phenomena on the Earth surface and its atmosphere. The followings are ASTER related information, which includes ASTER instrument, ASTER Ground Data System, ASTER Science Activities, ASTER Data Distribution and so on. ASTER Search provides services to search and order ASTER data products on the website.

ICGEM

International Centre for Global Earth Models

Subject(s)
Content type(s)
Country
The International Center for Global Earth Models collects and distributes historical and actual global gravity field models of the Earth and offers calculation service for derived quantities. In particular the tasks include: collecting and archiving of all existing global gravity field models, web interface for getting access to global gravity field models, web based visualization of the gravity field models their differences and their time variation, web based service for calculating different functionals of the gravity field models, web site for tutorials on spherical harmonics and the theory of the calculation service. As new service since 2016, ICGEM is providing a Digital Object Identifier (DOI) for the data set of the model (the coefficients).
