Yes, I already noticed that. But a run with thousand gcp's is still quite fast. I am looking for a smart way to segment these large maps. You cannot rubbersheet them in many  parts, because then the borders won't fit any more. The only thing I can come up with at the moment is creating common p

Hi all, I'm converting large historical vector maps with ogr2ogr, using -gcp and -tps to rubbersheet the polygons with control points. Works fine up to about a thousand control points, each in the form of "-gcp fromx fromy tox toy". After that, the converted map becomes erratic. Is this a bug?
