Airbus announced new pricing for all their 5-meter resolution DEM products along with new processing levels. WorldDEM Neo DSM with 5-meter resolution has a new low price, so reach out to us at sales@apollomapping.com to get your hands on our most recent digital elevation model (DEM) pricelist.
A sample of 5-meter WorldDEM Neo DSM data over Phu Hoi, Vietman.5-meter WorldDEM Neo DTM is now available as a Level 2 product with manual processing for better results. This includes the removal of surface structures from WorldDEM Neo DSM such as built-up areas and tall vegetation. It also incorporates the refinement of land cover borders before reducing the elevation to the terrain level and extending the preservation of ridge lines and canyons with the precise modelling of transport structure like bridges, motorways, embankments; and then also detailing the extents of hydrographic features like water bodies, reservoirs, and rivers, and respective alignment of water surface heights.
The Level 1 product is an automated DTM removing surface structures from WorldDEM Neo DSM for a more economical option, and when bundled with the DSM there’s considerable cost savings. Airbus tested the accuracy of WorldDEM Neo with respect to the global ICESat layer and updated the absolute vertical accuracy specification to an impressive < 1.4 m Linear Error 90% (LE90).
Finally, we have our first sample of the 5-meter DTM Level 1 product available to download for free. You can download the sample of Perry County Pennsylvania from our website, along with a 5-meter DSM of the same area. Airbus also offers a 12-meter WorldDEM product and its samples are free to download on this same page.
