I have georeferenced plenty of images which I would like to automatically rectify via a Python script. However, I face some troubles in applying a fixed pixel size to all of them.

What we did so far:

1) Setting the Links and exporting them to txt file

2) Update Georeference

3) Update Spatial Reference

4) set arcpy.env.cellSize to 0.000001 ( the data UAV imagery an in EPSG 4326)

4)apply  arcpy.Warp_management(tif_path, source_pnt, target_pnt, out_raster_path, transformation_type, resampling_type) OR arcpy.WarpFromFile_management(tif_path, out_raster_path,Link_txt_file, "POLYORDER2", "BILINEAR")

The warping itself works just fine, but the defined cellSize is not implemented. Are there any hints on what I'm doing wrong or missing out?

Manually rectifying the same image and defining the pixel size works, by the way.However, this is just very unhandy when targeting several hundreds of images...

Thanks!
