coordinate transformation

Post by anastasijaarsova »

Hey guys
i have the following problem
i have point cloud where the station point coordinates are switched(X is written instead of Y and Y instead of X north). So the point cloud is misplaced. Is there any way to transform the coordinates?

If it's an ASCII point cloud, then it's very simple to swap the column roles at loading time so as to change that.

Otherwise, you'll have to use the 'Edit > Apply transformation' matrix and provide a matrix that swaps the dimensions.

For your example (swapping X and Y), it will look like this:
0 1 0 0 0
1 0 0 0 0
0 0 1 0 0
0 0 0 0 1
