Hi folks,
I have a set of PNGs that I would like to add geo-referencing to.
Frankly, I'm not sure what projection they are in, but I do know the
bounding box in lat-long, and I think they are simple geo-coordinates.
I tried adding a *.pgw "world file", that looks like this:
0.04430379
0.0
0.0
-0.03201024
-85.0
45.0
That seems to get the basics: QGIS puts it in the right place on the
map, and gdal_translate seems to be able to make a geotiff out of it.
However, I'd like to be able to put a bit more information in, like that
it's wgs84, and geo-coordinates. How can I do that? It seems an
*.aux.xml file should be able to do what I want. but I don't what to put
in that.
Has anyone got a sample that I could follow?
Or is there another way?
-Chris
