In 2014, the White House, Government of the United States, announced the release of the Shuttle Radar Topography Mission 30 meter resolution global dataset, also known as SRTM-2. This is the highest quality digital elevation model (DEM) now publicly available. Among its many uses, the higher resolution data enables more accurate modeling of floods, coastal storm surges, mudslides, and volcanic lahar flows.

Following the announcement, the WGCapD set out to make 30m SRTM-2 data available to countries that need it through regionally focused workshops, hosted by respected institutions with expertise in DEMs. The workshops are being organized to help practitioners incorporate SRTM-2 data into their existing processes and projects, teaching them how to actively use 30m DEMs.

The first WGCapD-organized SRTM-2 workshop of 2015 was hosted in March 2015 by the South African National Space Agency (SANSA). The workshop targeted disaster management practitioners in the southern Africa region, with a particular emphasis on the TerraHidro and CREST flood models.

This workshop is being organized for practitioners in countries in the Latin America and Caribbean region (LAC) and will be particularly useful for those that are developing disaster early warning and emergency response systems. The range of common disasters to be addressed by these systems includes flooding events, which have a large impact on their economic and social development, and other disasters such as landslides.


The workshop is being organized by the Working Group on Capacity Building and Data Democracy (WGCapD) of the Committee on Earth Observation Satellites (CEOS), hosted by the Regional Centre for Space Science Education for Latin America and the Caribbean (CRECTEALC), and further supported by the Secure World Foundation (SWF), INAOE, BUAP, the Mesoamerican Centre for Theoretical Physics (MCTP), and the UN Office for Outer Space Affairs.


The objective of this workshop will be to build capacity in understanding and using 30m DEMs derived from SRTM-2 data in flood modeling and, time permitting, other applications.


The Topics for the workshop will include:

  • Overview of the SRTM-2 mission and data
  • Overview of hydrological models
  • Theory and hands-on exercises on using DEMs in a specific flood model (to be announced)
  • Case studies from the LAC region
  • Presentations on CEOS, GEO, GEOSS
  • Capacity-building resources made available by the supporting organizations
