AW3D Standard

AW3D Standard digital elevation model (DEM) data is the result of a joint venture between NTT Data, Remote Sensing Technology Center of Japan (RESTEC) and the Japan Aerospace Exploration Agency (JAXA). NTT Data and RESTEC utilize JAXA’s 2.5-meter (m) panchromatic ALOS satellite imagery taken from 2006 to 2011 to create 2.5-meter and 5-meter resolution digital surface models (DSMs) and digital terrain models (DTMs). The DEMs are derived from 3 million tri-stereo images, then corrected for gaps and anomalies, before they go through quality assurance tests.

AW3D Standard has off-the-shelf coverage for more than 80% of the Earth’s landmass, making it the highest resolution DEM with such comprehensive coverage. Its horizontal and vertical accuracy specification is 7-m LC90/LE90, which is based on analysis of the 5-m resolution product. For the 2.5-m resolution DEMs we can expect even better accuracy figures, though they are not yet published.

  • DEM Post Spacing (i.e. Resolution): 2.5 m (5 m also available)
  • Absolute Vertical Accuracy: 5 m RMSE / 7 m Linear Error 90% (LE90), dependent on slope of terrain
  • Absolute Horizontal Accuracy: 5 m RMSE / 7 m Circular Error 90% (CE90), dependent on slope of terrain
  • Data Source: ALOS tri-stereo panchromatic imagery
  • Available Formats: DSM and DTM

In a Hurry?

AW3D Standard DEMs are delivered quickly, especially the Level 1 DSM which often takes just a week to get the data in your hands.

Great Coverage + Ideal Resolution

More than 80% of the Earth’s surface is available as a DSM or DTM that can be purchased in 2.5-m or 5-m resolution.

No GCPs Needed

Straight out of the box, AW3D Standard has impressive accuracy specifications without demanding ground control points as the horizontal and vertical accuracy is 5-m RMSE or 7-m LC90/LE90.
