[GRASS-dev] GRASS 7 vector topology format changed

[Markus Metz]

Hi all,

the GRASS 7 vector topology format changed a bit. I have removed
redundant information (bounding boxes) from vector topology and
updated all affected components. The changes are numerous and require

make distclean
configure
make

This change also means that whenever you switch between GRASS 6.x and
GRASS 7, topology needs to be rebuilt, easiest done by using

v.build.all

The GRASS 7 format always consumes much less memory and is most of the
times, but not always, faster than the GRASS 6 format.

The network analysis modules should be a bit more robust now and can
easier detect errors in the networks.

The new format offers new possibilities for the v.surf.* modules
because it is now possible to build (parts of the) topology even for
massive point clouds which in turn makes it possible to quickly
perform spatial queries with very low memory consumption (a very few
MB).

Please test!
