PIX4Dcloud and PIX4Dcloud Advanced allow processing projects uploaded from PIX4Dcatch with a custom coordinate system defined by the user. This article explains the visualization of a Site Localization project on PIX4Dcloud.

Once the project has been processed, it is possible to view it in PIX4Dcloud. There are some differences in the user interface with respect to a standard project:

• Site Localization tag [1]: The tag added on the 2D/3D view indicates that the project is processed with a site localization file defining the custom coordinate system.
• Localization Points layer [2]: It contains all the points that were used to compute the Site Localization. 
• Download WTK string file [3]: Allows to download a file that defines the custom coordinate system. The file can also be imported into PIX4Dmatic for processing projects. 
• Site localization point: By clicking on each point, the following information is displayed: 
  • Local coordinates [4]: Refers to point measure in the custom coordinate system defined by the user.
  • Global coordinate [5]: Coordinates of the point of the selected global coordinate system in PIX4Dcatch + viDoc. 
  • Residuals [6]: Residuals of the transformation from a global to a custom coordinate system at that point.
• Coordinate system switcher [7]: It shows the name of the custom coordinate system given on PIX4Dcatch + viDoc.
