Re: [GRASS-user] too many categories: buffer overflow

It looks like you've run out of integer values for the "category" primary key. Do you really want a vector polygon map with > 2 billion features?

This is a hard one to search for with GRASS GIS because the word "buffer" and "overflow" appear throughout as in r.buffer and overflowing weirs, etc. but I'm referring to the C-code error type of buffer oveflow: r.to.vect -v input=basins output=basins type=area DBMI-SQLite driver error: Error in sqlite3_step(): UNIQUE constraint failed: basins.cat ERROR: Unable to insert into table: insert into basins values ( -2137121269, '(Category -2137121269)') Does anyone have any suggestion how I can convert a raster with MANY categories to a vector?
