How to integrate Lat/Lon bands into re-projection

OTB Usage
1

Hi,
I’m trying to produce a geo-referenced TIF file based on the following inputs:

  1. raster with image data
  2. raster with longitude data (for each pixel in the raster, the value associated is the longitude)
  3. raster with latitude data (same structure as 2 above).

So the question is how can I take advantage of this information to re-project into a map projection (from geographic)? I was hoping to use the orthorectification module but I’m not sure how to prepare the location information so that it is taken into account during the ortho process.

Is there a simple method that I’m missing? Or do I need to produce an output raster in the wanted map projection and associate each pixel/line to the lat/lon raster using the appropriate transform?

Thanks in advance for your help,
Conrad

Hi @riscognition_user

I don’t really understand your use case, your raster image is in SENSOR geometry and you want it projected on a map ? Then you should use OrthoRectification. There are parameters that you can use in orthorectification to specify the projection with the “-map” parameter. The documentation is here

If you want to reproject an image using the geometry from another image, then you can use SuperImpose
