Hey all, So I have a strange issue that I somewhat isolated, but I don't know how to move further. I have dataset in EPSG 31468-15949
My goal is to tile it, render it with openlayers, and add a marker on the GCP location. Trouble is that the GCP location was falling a bit away from the marker image. I had a hard time investigating that, and I still do but I realized that tiling in other conditions did work perfectly. So in Production - I have a docker image which is basically osgeo/gdal:alpine-normal-3.0.2 - this means GDAL 3.0.2 - PROJ 6.2.1 If I use this docker to do the tiling, then I get the "badly aligned" tile. On my local MAC - I have gdal 3.0.1 installed from the brew repository osgeo/osgeo4mac/osgeo-gdal - I have proj 6.2.0 - I have the GDAL 3.0.1 pip package installed If I use my MAC to tile, I get the "aligned" tile And that's it, I'm stuck. I tried in a python shell to do coordinates transform of the GCP from the source WKT to EPSG 3857 and I get the same value whether in the docker or on my MAC Any idea how I can move further? I have put a zip with some data here https://prod-pix4d-public-assets.s3.amazonaws.com/issue_investigation/Investigation_tile_alignment.zip Thanks --- Gregory Bataille
