The goal is to make converting scanned paper maps to map tiles as easy as possible.
I've done a few, but the slow part is manually entering coordinates of points. What I'd like to do is for each point on the scanned paper map, click on a satellite image (ie a Google Map) to automatically set its coordinates. I know this should be possible with QGIS and the georeferencer plugin (I'm using 1.7.2) but...
If I set QGIS to use WGS84 projection, I haven't found a way to display Google Maps in QGIS so that the georeferencer plugin tool will take coordinates from it.
If I set QGIS to use EPSG:900913, I can use the Openlayers plugin to add a Google Maps layer, and the georeferencer plugin tool happily takes coordinates from it. But gdal2tiles won't process the resulting geotiff file that georeferencer produces.
So currently I set QGIS and georeferencer to use WGS84, type in lat/lon pairs manually, and then gdal2tiles processes the resulting geotiff successfully.
Has anyone found a workflow that avoids the problems I described above?
Thanks & regards, David
