Geo-referencing and Checkpoints

Geo-referencing and Checkpoints

The correct use of geo-referencing and checkpoints is crucial for the accuracy of your site models. In this video, we walk you through:

  1. Importing GCP's (ground control points) to the wizard
  2. Selecting the relevant coordinate system
  3. Marking the GCP's (at least three)
  4. Checking accuracy calculations
  5. Marking additional of the GCP's using hints
  6. Revalidating the accuracy
  7. Setting checkpoints (at least one)
  8. Generating the models
