Hi list,
I have a large point theme (representing addresses with a column for the
street, housenumber, ...), from which I would like to extract (using
v.extract) only few. Therefore, I am looking for the best way to do so. Is it
possible to select the entries step by step (something like add to current
selection) and then extract the complete selection?
I am asking this, because I find it hard to write down the whole sql-statement
in one command (and therefore a growing likelihood of making errors).
Or can I store the sql-statement somewhere and re-use it with different
commands?
I would be happy to read your suggestions!
Best regards,
Wolfgang
Hey Fellow GRASSers:
I am trying to combine vector maps (two at a time) using v.overlay, and I also
want their full attribute tables merged.
The problem is, GRASS shuts down when I run the command. The x11 command window
tells me that a Bus error closed the GIS manager.
I end up with an output map with the name of the new vector I attempted to
create, but the data are missing for the merged locales.
I am running a nearly-most-recent cvs (within 2 weeks, cannot connect my Mac to
the internet currently due to the lack of a place to do so....), and I run
GRASS fully within X11 (the display manager is afster than running on the
native mac). The vectors I am trying to combine are polygons of archaeological
sites, with attribute tables that contain the same exact field names (i.e.,
site number, affiliation, type, etc etc).
Any suggestions?
Thanks,
Brandon
