Examples of DEMs at 5m Resolution

Geoimage is able to supply clients with a 5m DEM generated from ALOS PRISM data. The ALOS World 3D Topographic Data product, known as AW3D, is currently being produced by Japanese companies RESTEC/NTT Data and will eventually be an "off the shelf" product.

AW3D uses the extensive archive stereo coverage that was collected by ALOS PRISM during the period 2005-2011. All suitable scenes within the archive have been "stacked", to assist cloud masking, and then a DEM is generated. Depending on the client's target area, this product can either be purchased immediately, or can be included within the AW3D processing chain.
