"Topology is written for native format while pseudo-topology is written for OGR sources, SHAPE-link." Please, forgive me, but I would like to clarify some points more. 1 - v.external links to data without topology buing built. At the moment it's only useful for visualizing (but could it be used for SF algorithms?) 2 - OGR data sources use "pseudo-topology". Does this refer to the read/write directly accessed sources? Or is it general? What is the main difference between pseudo- and real- topology? thanks again, giovanni 2010/4/6 Martin Landa <[email protected]>: > [back to ML] > > Hi, > > 2010/4/6 G.
