# Name: gdalcopyproj.py
|
|
# Project: GDAL Python Interface
|
|
# Purpose: Duplicate the geotransform and projection metadata from
|
|
# one raster dataset to another, which can be useful after
|
|
# performing image manipulations with other software that
|
|
# ignores or discards georeferencing metadata.
