Introduction

For more information, please read the block description.

Block type: DATA

WorldDEM™ Streaming Service is a Digital Surface Model (DSM) with unprecedented quality, accuracy and coverage. The dataset models the surface of the Earth including buildings, infrastructure and vegetation at a spatial resolution of 12m and it is delivered in GeoTIFF format.

The WorldDEM™ products are based on the radar satellite data acquired during the TanDEM-X Mission, a joint partnership between the German Aerospace Centre (DLR) and Airbus Defence and Space. The primary goal of the mission was the generation of a worldwide, consistent, and high precision Digital Surface Model (DSM) based on SAR interferometry.

The satellites TerraSAR-X and TanDEM-X operated as a single-pass SAR interferometer (InSAR), using the bi-static InSAR StripMap mode. At least 2 complete data coverages of the Earth’s surface were acquired to generate this product. The data acquisition started in January 2011 and was completed by mid-2015.

For more details, please refer to WorldDEM Product Specification.

Supported parameters

For more information, please read the section Data source query filters.

  • bbox: The bounding box to use as an AOI. Will return all data points within this box. Use only bbox or intersects.

  • intersects: A GeoJSON geometry to use as an AOI. Will return all data points that are within this geometry. Use only bbox or intersects.

The AOI size must be larger than 0.1 square kilometers.
