NakedEarth

NakedEarth provides Digital Terrain Models (DTM) that focus on terrain retention while removing surface features. This high-quality 30-meter DTM maintains the input Digital Surface Model (DSM) seamlessly and void-free with flattened water bodies. 

NakedEarth is processed with Novlum’s proprietary DSM-to-DTM generation system. It is derived from the globally available AW3D 30 Digital Surface Model (DSM), collected by the Advanced Land Observation Satellite (ALOS, © JAXA). It is available off-the-shelf for the entire globe.

The Novlum DTM Processing System provides the following features:

  • Proprietary and fully-automated DSM-to-DTM generation software
  • Artifact removal and void fill
  • Terrain preservation (breaklines)
  • Surface features removal (buildings, vegetation)
  • Flattening of water bodies
  • Maintaining accuracy, quality, and consistency of input DSM (statistically and qualitatively)

Input Data for NakedEarth generation:

  • Digital Surface Model: AW3D30 (© JAXA)
  • Forest Map (Univ. of Maryland)
  • Settlement Map (European Commission)
  • Water Body Data (SRTM, USGS)
  • Road network (Open Street Maps)

The above-mentioned input data for the generation of NakedEarth make this service highly flexible and beneficial to customers working in agriculture, forestry, land planning, construction, and more. With instant access to any area in the world, NakedEarth is suitable for time-critical applications, e.g., natural disaster management and flood modeling, as well as cloud applications. Ideal for orthorectified imagery, mapping, 3D visualization, and modeling surface processes on a large or even global scale.
