Georeferencing GPS coordinates - coordinates too big.

Post by arjun »

Hi,

I've got OS coordinates down a mine and would like to georeference my clouds using spheres we have picked up.

I've used the align tool to do this, but it says the coordinates are "too big". I've reduced down the coordinates to something cloudcompare will handle, but as I now need to digitise the cloud in a survey package, I need to shift it to its correct position, so in essence add 78.268m Easting, 77.542m Northing back on so the mine will be in the correct position.

How do I do this?

Thanks

Hi,

First, when CC complains that coordinates are too big, you should always have the option to let CC 'shift' them automatically (in which case it will handle the shifting in the other way at export time).

But you can also do it by hand indeed, by setting yourself the 'Global shift' associated to the cloud:
- select the cloud
- go to "Edit > Edit global shift & scale"
- change the shift values with the negative shift values (-78.268m Easting and -77.542m Northing). Check the left panel to confirm tihis

With this information, CC will apply the (inverse) shift at export time.
