I have a point cloud and would like to move this to the local coordinate system for example from Revit facing toward the first quadrant. We have a file with 3 ground reference points and on-site marked with blocks. So it is possible for us to get the coordinates from the point cloud so, we have:

  • 3 ground reference points in RDNew
  • 3 reference points in the point cloud from the 3 blocks
  • an Origin point for the absolute 0,0,0 coordinates

We want to move the point cloud to the local coordinate system and rotate towards the first quadrant.

How can I perform this transformation with for example a proj4 string?

  • Welcome to GIS SE! We're a little different from other sites. We're a Q&A site, not a discussion forum. For questions that involve code we ask that you show us where you are stuck with your own code by including a code snippet in your question. There is an edit button beneath your question which will enable you to do that and a {} button that enables you to format any highlighted code nicely. Please check out our short tour for more about how the site works. Thanks. – PolyGeo May 28 '19 at 8:43

    Your title says WGS84 (latitude,longitude) but the body of the question implies that the point cloud coordinates are in a local xyz system. Which one is correct? – mkennedy May 28 '19 at 17:50
