<br> Hi,<br><br>1)Thinking about exchanging Grass vector data between users, I was wondering wich is the the best format to export GRASS vectors, so that they keep GRASS vectors characteristics like two areas sharing the same boundary, the use of centroids, multilayers and database. Any clue?<br><br>2)Here in Brazil, ESRI shapefile is the "industry standard" for gis data exchange, is there any "Open Source standard"?<br><br><br>Thanks!<br><br>Pablo Torres Carreira
