Hi,
I am working here in Chile and we have a lot of earthquakes here, the last
big one like a year ago. So the problem is that I have a lot of
georeferenced images, but georeferenced before the earthquake. We thought
the best way would be to calculate a shift grid and apply it with gdalwarp
to
Frederick,
I'm a geophysicist but never thought that an earthquake could have that
side effect of image referencing.
Anyway the horizontal deformation caused by a big earthquake is of the
order of meter scale. One idea I had is that you can use the shift grid
to to relocate previous GCPs and
