hi GRASS community! I'm amazed how well this software handles vector operations - especially the overlay operation seems unparalleled in open source software. Thank you very much to everyone who has been involved in the development process!
I would like to script a workflow where I apply the same set of operations on a few hundred sets of shapefiles, consisting of v.in.ogr, several sets of v.overlay, some database operations and v.out.ogr. The shapefiles are 20-30MB apiece, containing many polygons, each with many vertices. Is there a difference in speed or processor efficiency between the different scripting approaches? By which I mean python vs bash shell, and within the GRASS environment vs calling the functions from outside the environment (like via python grass.script). Thank you for any opinions or advice! -Wiley
