[GRASS-dev] Google Summer Of Code Project

[Helena Mitasova]

We will try to get out a new, more modern data set that is planned as  
a replacement for spearfish,
it has been already tested with almost every raster module and most  
vector modules,
we just need to cleanup the names and add metadata. The data set has  
at least building footprints
so you can generate simple buildings using v.extrude, but I am  
working on getting
some real buildings data too. Let me discuss with Markus the best way  
to provide
the data set for early testers/developers.
