SRTM Mission

Shuttle Radar Topography Mission (SRTM)

Space Shuttle Endeavour during the 11-day STS-99 mission in February 2000 Used a technique known as Interferometric Synthetic Aperture Radar to generate a DEM at a near global extent of 56° S to 60° N

Global Multi-resolution Terrain Elevation Data 2010

Primary Goal

Developed a global medium scale elevation model to replace GTOPO30. Generated seven products at three separate resolutions (horizontal post spacings)

  • f 30 arc-seconds (1 km), 15 arc-seconds (500 m),

and 7.5 arc-seconds (250 m) from the best available higher resolution data sources.

Objectives

  • Enhance South America’s (SA) regional

Spatial Data Infrastructures (SDI).

  • Provide open access to the Shuttle Radar

Topography Mission (SRTM) 1 arc-second (~30 meter) Digital Elevation Model (DEM) derivative products*.

  • Develop a data distribution service that can

efficiently adapt to the needs of its users.

* Only derivative product approved by U.S. National Geospatial-Intelligence Agency (NGA).

Approach / Rationale

Approach

  • Provide a dynamic service that can efficiently adapt to

the user community's requirements.

Rationale

  • Developing services that generate products

dynamically rather than prepossessed giving the user an opportunity to define the requirements of a product.

  • The Web service approach provides an efficient

environment to create new products that meet the ever changing needs of the GeoSUR user community.

Result

Topographic Processing Service (TPS)

  • The TPS provides a geo-processing Web service

accessible through GeoSUR’s Regional Map Service (RMS), ESRI’s ArcGIS desktop software, Python scripting environment, and has a JavaScript API for custom Web development.

  • The service allows users to request 6 SRTM 30-m

derivative products: slope, slope classification, aspect, shaded relief, classified elevation and an elevation profile report.
