May 30, 2018 at 11:36 comment added Roman Perkhaliuk I'm looking for some tool or algorithm that can help to make those boundaries automatically (there's a lot of similar). maybe some raster processing techniques or maybe should I dig in machine learning?
May 30, 2018 at 11:32 comment added Roman Perkhaliuk Yes, my mosaic is a single file. And I need to get boundaries of each image in the mosaic (like those, I digitized in red lines). And yes red polygons are a vector file.
May 30, 2018 at 10:36 comment added dmci can you clarify if your mosaic is a single file (e.g. GeoTiff) or Virtual Raster? Also, are the red boundaries in the second image of your question, individual polygons in a vector (shapefile) file?
May 30, 2018 at 10:35 comment added Basile I don't think it is possible if your msaic is already merged composite.
May 30, 2018 at 8:28 comment added Roman Perkhaliuk I've clarified my question. Please check it again.

May 30, 2018 at 8:11 comment added Basile Do you need a boundary for a whole raster, including "No Data" area, or just footpronts for imaged area?
May 30, 2018 at 8:06 comment added Roman Perkhaliuk No, I mean each different element in each of that three rasters
