General Workflow

Work with surface modeling normally follows this process:

  1. Data import – Point clouds or existing models are imported into the project.

  2. Preparation of data – Data is reviewed, cleaned for noise, and reduced if necessary to achieve the right level of detail and a manageable data volume.

  3. Editing and delimitation – Relevant areas are extracted, unwanted points are removed, and the dataset is adapted to the intended use.

  4. Triangulation and model building – The point cloud is used directly in analyses or converted into triangle networks and terrain models.

  5. Combination and further processing – Multiple models or triangle networks can be merged and prioritized against each other.

  6. Control, analysis, and documentation – Completed models are used for difference analyses, volume and area calculations, visualization, and export.

This workflow is common when processing scanned terrain data and aligns with generally accepted practice for establishing digital surface models.
