A while back I noted that if patching very large numbers of files, GRASS 6.3 generates frequent topo errors:
ERROR: BUG (Vect_build_sidx_from_topo): area does not exist This can be reproduced in Spearfish: 1) Create individual points for i in `echo "select cat from bugsites" | db.select`; do v.extract input=$i output="bugsites_""$i" where=cat=$i; done 2) Buffer individual points for i in `g.mlist vect pattern="bugsites_*"`; do v.buffer input=$i output="buffer_""$i" buffer=500; done 3) Add tables to buffers for i in `g.mlist vect pattern="buffer_*"`; do v.db.addtable map=$i; done 4) Overlay buffers with areas for i in `g.mlist vect pattern="buffer_*"; do v.overlay ainput=$i binput=trn_sites output="overlay_""$i" operator=and; done 5) Create target patch map for i in `g.mlist vect pattern="overlay_*"`; do v.patch -a -e input=$i output=patch --overwrite; done Can anyone suggest solutions? It would be nice to avoid having to patch a bunch of maps by hand to avoid the error!
