Annotations that can be created and exported from Pix4D Cloud are distances, areas (including their perimeters), and markers. Measurements rely on geolocation. The measurement unit, imperial or metric, is the one selected in the account settings. For more information: 215858503. Annotations created in the Map view do not affect the 3D Model view and vice versa. It means annotations are not automatically transferred from one view to the other.
Measurements and markers have the following characteristics depending on the output coordinate system, known or arbitrary, and whether the images are processed on the cloud servers or not.
- Horizontal: Latitude and longitude in WGS84 (decimal degrees).
- Vertical: Default vertical datum (meters or feet according to the account preferences).
- Images uploaded via Pix4D Cloud web platform: Same as the images, which also applies to all resulting outputs.
- Project uploaded from Pix4D Desktop: Same as the outputs according to the selected options. For more information: 202560029.
|Cases||Map view||3D Model view|
Project is processed AND output coordinate system is known
Default horizontal coordinates.
Default horizontal and vertical coordinates.
Only results are uploaded
Output coordinate system is arbitrary
1. The .tif file contains geolocation data (GeoTIFF format): Default horizontal coordinates apply.
2. The .tif is not georeferenced: Coordinates are computed with respect to an arbitrary project origin (0, 0).
1. Point cloud (.las) is available: Coordinates are extracted from the uploaded .las file directly so the X, Y, Z values are in the output coordinate system.
2. Only mesh (.obj) is available: Coordinates are computed with respect to an arbitrary project origin (0, 0, 0).
There are three possible formats:
- GeoJSON (georeferenced annotations): Available in both the 2D Map and 3D Model views.
- Shapefile (georeferenced annotations): Available in the 2D Map view.
- CSV (properties of the annotations only): Available in both the 2D Map and 3D Model views.
Annotations cannot be exported individually, they are all exported at once:
1. Ensure each annotation has the desired name and optionally, a description.
2. On the left sidebar, click Annotations. This highlights all annotations in the current view.
3. On the right sidebar, select the export format. Clicking automatically starts the download.
