    The NEXTMap Elevation Data Suite from Intermap Technologies is now offered on the UP42 developer platform for Earth observation data and analytics. UP42 gives users direct access to extensive Earth observation datasets and advanced processing algorithms, and Intermap Technologies, based in Englewood, Colorado, is a provider of geospatial datasets, solutions and software.

    The NEXTMap 3D elevation products are available as digital surface models and digital terrain models at one-, five- and 10-meter resolution. According to Intermap, NEXTMap One offers 1-meter spatial resolution, 1-meter vertical and 3.5-meter horizontal accuracy; NEXTMap 5 offers 5-meter resolution, 1.6-meter vertical and 3.5-meter horizontal accuracy; and NEXTMap 10 offers 10-meter resolution, 8.4-meter vertical and 17.5-meter horizontal accuracy.

    “We are excited to add NEXTMap elevation models to the UP42 platform. Our customers need this data for a range of use cases, including monitoring of vital infrastructure projects such as pipelines, powerlines and railway corridors,” said Sean Wiid, CEO of UP42. “High-quality 3D data is critical in every phase of infrastructure management from construction planning to ongoing monitoring of vegetation encroachment.”

    The addition of NEXTMap datasets to the UP42 marketplace enables users to build even more powerful geospatial solutions in the areas of infrastructure management, construction planning, geologic mapping, land cover classification, forestry, resource conservation and contour generation, UP42 said.

    “Our goal at UP42 is to create a single platform where our users have access to all the geospatial data, analytics and processing infrastructure they need to build solutions that solve critical real world problems,” said Wiid. “Intermap’s NEXTMap elevation models dramatically expand our core data offering and, as a result, expand the range of use cases we can help our customers address.”

    The NEXTMap datasets join a variety of Earth observation information already on the UP42 marketplace, including Pleiades 1A/B, SPOT 6/7, Landsat-8, TerraSar-X, Sentinel-2 and MODIS satellite imagery, Getmapping U.K. aerial data, exactEarth AIS data, and Meteomatics weather and ocean data.

  • Airbus Launches WorldDEM Digital Terrain Model

    Airbus Defence and Space has launched its WorldDEM Digital Terrain Model (DTM), a highly accurate standardized representation of bare Earth elevation that can be made available for any point on the globe. This addition completes the WorldDEM portfolio, enabling Airbus Defence and Space to provide both surface and terrain elevation information in support of global customer projects.

    WorldDEM DTM can be delivered for more than 90 Million km² of the Earth’s landmass.

    The WorldDEM DTM is derived from the WorldDEM product (Digital Surface Model) by removing all man-made features and vegetation. The quality of the original WorldDEM product combined with a sophisticated editing process guarantees highly precise and consistent terrain information, Airbus said. While surface features (such as built-up areas and vegetation) are reliably removed, characteristic terrain features such as ridge lines or mountain crests are preserved.

    The WorldDEM DTM provides an excellent foundation layer for a wide range of applications such as civil engineering (road design, earthwork calculation), the management of natural resources (such as flood modeling), mapping (such as derivation of contour lines) as well as military mission planning (vehicle trafficability analysis, 3D terrain visualization).

     WorldDEM is based on data acquired by the high-resolution radar satellites TerraSAR-X and TanDEM-X, which started synchronous data acquisition in December 2010 and completed coverage of the Earth’s entire landmass twice over in mid-2013. The satellites covered more complex terrain areas with a third and fourth acquisition campaign to ensure consistent high quality and accuracy of the final product. WorldDEM provides the first global, single-source, high-precision Digital Surface Model and has established a new standard of global elevation models.
