NEXTMap One - Elevation Data (Streaming)

Provides NEXTMap One DSM and DTM at 1 meter resolution.

Analytics platform discontinued after January 31, 2024

The current analytics platform will be discontinued after January 31, 2024, and will be replaced by new advanced processing functionalities. This change will affect projects, workflows, jobs, data blocks, processing blocks, and custom blocks. For more information, see the blog post.


A data block that provides streamed high resolution elevation data acquired on a global basis. The datasets are available as a digital terrain model (DTM) and digital surface model (DSM).

Technical information


  1. The DSM is hydro-enforced and includes surface elevations from terrain, vegetation and cultural features (buildings, roads).
  2. The DTM is hydro-enforced and includes the bare earth, where surface features (buildings, vegetation etc.) have been removed.
