[GRASS-user] v.univar column type in SQLite
Dear List I am working in DEBIAN lenny with a backported grass64 and i am experiencing problems with varios vector modules which make use of v.univar (or v.db.univar or v.univar.sh) in connection with SQLite databases. The question is: which column type v.univar supports, as a table created with CREATE TABLE master (id INTEGER, value NUMERIC); or CREATE TABLE master (id INTEGER, value DOUBLE PRECISION); or CREATE TABLE master (id INTEGER, value INTEGER); fails after a command like this: $ v.db.connect map=test data=/path/test.db driver=sqlite lay=1 table=master cat=id $ v.univar map=test column=value WARNING: Incompatible vector type(s) specified, only number of features, minimum, maximum and range can be calculated ERROR: Column type not supported I have searched into .h files but it seems that INTEGER, NUMERIC and DOUBLE PRECISION are indeed supported (there is no problem if the vector is reconnected with a DBF table). am i doing something wrong?

This layer keeps the values of the field "cat" of the attribute table. However I need this layer to be based on the second field of the attribute table and not on the "cat" field. Is this possible?

Re: [GRASS-user] convert to utm projection
Hi Rashad, You will have to create a new location for the same extent as your data in lat/long but this time specify the projection for the location as UTM. Then make this new location and mapset your working grass space. Now use v.proj OR r.proj to pull in the file from the lat/long location and mapset to the new location you just created. This should change the projection from lat/long to UTM.
