Getting started

New dataset > Processing options > Output coordinate system - PIX4Dcloud

Create a new dataset to start processing imagery and create maps and digital twins of the reality or upload outputs to PIX4Dcloud.

Access: To select the output coordinate system and the project template, navigate to step 3 of the project wizard.

Output coordinate system

For all processing templates defined in PIX4cloud, it is possible to define the horizontal coordinate system for the project outputs. Note that in the case of the 3D maps template, it is also possible to define the vertical coordinate reference system depending on the type of processing pipeline selected.

Horizontal output coordinate system

Select the horizontal coordinate system for the project outputs:

  • Drag and drop a PRJ file defining the coordinate system.
  • Search for the name of the coordinate system based on: EPSG code (use numbers only).
Information: By default, the output coordinate system is:
  • WGS84 / UTM Zone XX if the images are in WGS84. The UTM zone is computed based on the image EXIF information.
  • Arbitrary if the images are not geolocated.

Vertical coordinate system

At the moment, only in the case of the 3D map template with the new pipeline, is it possible to select the vertical coordinate system, the geoid model, and the geoid height.

Geoid model: Several geoid models are available in the PIX4Dcloud.Note that this same list of geoids are the same ones available from PIX4Dcatch. The full list is available in the following link, Which geoids are compatible with PIX4Dcatch and the viDoc RTK rover?.

Geoid height: When the geoid corresponding to the selected vertical reference frame is not available, it is possible to specify the Geoid height value, which represents the height between the base ellipsoid of the horizontal coordinate reference system and the desired geoid.

To select the vertical coordinate system:

  1. In the Vertical coordinate reference system dialog, search or copy-paste:
    • The name or,
    • The EPSG code of the coordinate system.
  2. According to the case, select also:
    • Ellipsoidal height as vertical above the geoid, or
    • Geoid model, or
    • Geoid height.
  3. Click Next.
