Model Reprocessing & Editing Geo-Referencing Method

Model Reprocessing & Editing Geo-Referencing Method


DatuBIM users can reprocess drone imagery and data to improve model accuracy by adding ground control points (GCPs) or simply changing the geo-referencing method. Reprocessing a model can be done without the need to open a new site and re-upload images. Here are some basic rules:

Basic Rules

  1. When you want to edit the geo-referencing method, DatuBIM will automatically show you only the available options that you can change them to.
  2. If the current geo-referencing method is one of the available options, it will automatically be selected, and the "Reprocess model" button becomes clickable. This workflow allows you to reprocess the model without making any changes or, in the case you are using GCPs, to add GCPs or correct the existing GCPs to improve accuracy.
  3. Reprocessing a model uses up credits of your image allowance, which is defined in your DatuBIM service package. 

Editing a Flight's Geo-referencing Method

To edit the geo-referencing method of a flight that was already processed, hover your mouse over the desired flight in the top flight timeline. The flight information will appear with a pencil icon in the top right corner, as shown in the figure below.  Click the pencil to edit the flight.

This opens the Edit Flight Data dialog, which shows you the available geo-referencing options. You may keep the currently selected one or change it. Then press the "Reprocess model" to move to the next step.



Besides changing to the different geo-referencing method, you can use Model Reprocessing to:
  1. Introduce a new, more accurate set of GCPs.
  2. Fix the coordinates of existing GCPs.
  3. Change additional processing parameters, such as Switch RTK on/off, Switch Rolling Shutter compensation on/off.

Reprocessing the Model

Depending on the selected geo-referencing method, pressing the "Reprocess model" button will be lead to different scenarios
  1. If the geo-referencing selection does not need any intervention from the user, the process simply completes all the way to the end.
  2. If the geo-referencing selection requires working on GCP's, the system puts the model in "Pending GCP Marking" status and waits for the user to take action.
 When reprocessing older models, you can take advantage of the full power and recent improvements of DatuBIM, such as:
  1. Enhanced pre-processing methods
  2. Quality checks of imagery
  3. Use of checkpoints
  4. Accuracy reports
  5. Upgrades to our photogrammetry engine
