Coordinate system handling in PIX4Dsurvey


Project coordinate system

The coordinate reference system of the project is automatically defined based on the coordinate system of:

  • PIX4Dmapper or PIX4Dmatic project file.
  • Coordinate system written in the metadata of the imported point cloud.

Transformation of import files

Imported files can be transformed when importing them into PIX4Dsurvey to ensure that they overlay correctly with other data. The following file formats can be transformed:

  • Point cloud in .las and .laz file formats.
  • .dxf files with 2D and 3D objects.
Example: When using:
  • A point cloud in geographic coordinate system WGS84 - EPSG:4326.
  • Project in projected coordinate system WGS 84 / UTM zone 32N - EPSG:32632.
The point cloud can be transformed into WGS 84 / UTM zone 32N - EPSG:32632 to align with the rest of data.
Tip: Since PIX4Dmapper does not directly support all vertical coordinate reference systems many project are defined as arbitrary. In those cases, the import dialog in PIX4Dsurvey can add the correct vertical reference system and make sure that the imported files correctly align with other data.
