====== Prepare UAS Data using Pix4D ======

After processing your UAS project using Pix4D software, you have created the following datasets:
  * a Dense Point Cloud (las)
  * an Orthomosaic (tif)

====  Dense Point Cloud ====

Because the import procedure for Pix4D processed data into 'Orbit UAS Mapping' already takes care of the conversion of a las file into an opc file, no further preparatory action is needed.

====  Convert Orthomosaic ====

Although the use of the ortho is not necessary to create an Orbit Run, you find here a short description.

Convert the Orthomosaic tif file into omi format to make it easiliy available in 'Orbit US Mapping' taking multiresolution and image compression into account, creating a fast view access.

This is done using functionality in the 'Orbit UAS Mapping' software.
\\ See further detailed information on how to convert in [[https://orbitgt.com/kb/170/desktop/tools/convert_data|https://orbitgt.com/kb/170/desktop/tools/convert_data]]


====  Export the undistorted images ====

The only function you still have to perform in the Pix4D software is saving the undistorted images.

Process > Save Undistorted Images 

  - Select 'Process' in the main menu of Pix4D, and select the method 'Save Undistorted Images'. 

Pix4D will start immediatly saving the undistorted images under the projects folder > 1_initial > images > undistorted_images

====  Cameras ====

All information about cameras is already saved by Pix4D under the projects folder > 1_initial > params.

==== Generate Report ====

A pdf-report is automatically saved under the projects folder > 1_initial > report.

==== Import the Project ====

Now you are ready to import the project into 'Orbit UAS Mapping'.
