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.
I would convert them to geotiffs with -a_srs option for telling it is in wgs84.
gdal_translate -of GTiff -a_srs epsg:4326 image.png image.tif
thanks -- by adding the world file, then using that to convert to
geotiff, I do get what I want. I can now use gdal_translate to convert
back to png, and I get a .aux.xml file that is what I want.
Thanks,
