Photoshop question

Post by Bullit » 20 Nov 2017, 00:08

I have an map that i want to preserve it's distance between cities etc. , in short maintain its projection.
I have another map that is shows other kind information of the same zone - sea depth etc - but has another projection and want to wrap it in a way that respects first map projection. What is the best way to do this?

Can be old Photoshop version or Krita/Gimp.

Affinity Photo has something like this, you can set some points and later move them around and the picture along with them. Maybe you can use a trial.

I think I've seen in somewhere else but I don't remember where.

Thanks rray. My preliminary search didn't came up with anything except the usual wrap techniques.

Krita's got a warp too that seems alright you could put points on the cities and drag them to the positions on the other map. Rest should follow, more or less.

For perfect results you probably need some GIS Software like GlobalMapper.

Yes I would put the map in a layer with 50 % transparency so you can see the other map through it.

Then transform tool (ctrl+t), then in its tool options use "warp" (middle icon). Choose "draw" to add points, then lock the points.

After that you can move the points and try some options for anchor strength
