With a project captured with PIX4Dcatch and the viDoc RTK rover, several options exist for processing a 3D model. Directly upload and process to PIX4Dcloud / PIX4Dcloud Advanced for the most immediate results, or export the project and process using PIX4Dmatic or PIX4Dmapper.
Regardless of the chosen option, the model is extracted from images that are accurately geotagged by the viDoc RTK rover.

For fast results, uploading and processing with PIX4Dcloud / PIX4Dcloud Advanced can provide quick shareable 3D reconstructions.
Upload directly from the project
Captured project ready for upload.
After capturing a project, upload directly to PIX4Dcloud / PIX4Dcloud Advanced for processing by tapping Upload 
at the top of the screen.
Upload from the Projects screen
It is also possible to upload from the Projects screen, which lists all of the projects taken on the mobile device.
1. Tap the folder icon 
to access the Projects screen.
2. Select the project and upload it.
- For iOS:
PIX4Dcatch iOS Project menu.
- Tap and hold on the desired project to access the menu.
- Tap Upload.
- For Android:
PIX4Dcatch Android project menu has two options for upload.
- Method 1:
- Tap and hold on the desired project to access the menu.
- Tap Upload .
- Method 2:
- Tap the expand icon
for the project. - Tap Upload.
Processing options
After tapping Upload the Upload project window appears providing further processing options.
Projects can be uploaded as a New Dataset, or Assign To a new or existing site in PIX4Dcloud Advanced. For more info on the site option: New site - PIX4Dcloud Advanced.
Upload Project dialog.
Measure Volumes and Elevation Profiles: Select this option to generate a DSM of the area.
2D Map: Select this option to generate an Orthomosaic.
Output coordinate system: It is possible to select the output coordinate reference system for projects captured with the viDoc RTK rover. Auto Detected selects the UTM zone corresponding to the project's location.
- Click the Output coordinate system tab to select a known coordinate reference system.
Select Output CRS dialog.
- Select the desired coordinate reference system.
Choose the horizontal coordinate reference system.
Choose the vertical coordinate reference system.
Select the geoid when available. If no geoid is available, it is possible to enter the geoid height over the ellipsoid.
- Select Done.
Note: When a local geoid is not available, it is possible to enter the geoid height over the ellipsoid to obtain geoidal heights for the project.Enter the average geoid height over the ellipsoid for the area scanned.
Once the selections are complete, tap Upload at the top of the screen to start uploading. An email is sent when all images are uploaded and processing begins. A second email is sent when processing is finished. After the processing is finished, the results can be viewed and shared on PIX4Dcloud.
Export and process locally with PIX4Dmapper or PIX4Dmatic
1. Export the project from the device to the computer. For more information: How to export PIX4Dcatch projects (iOS/Android).
2. Create a new project and start processing using PIX4Dmapper/PIX4Dmatic. For more information:
- New project in PIX4Dmapper.
- How to process PIX4Dcatch datasets in PIX4Dmatic.
- Video: Process PIX4Dcatch data with PIX4Dmatic.
3. After the processing is finished, the results are available for further analysis in PIX4Dmapper/PIX4Dmatic.
