Hi,
I am a new grass user and I would like to know if it is possible to use grass
to deal with geological data, i.e. plane orientations, lineations...
Has someone already done that kind of things and would be ready to share his
experience?
By the way I am having some troubles while importing shapfiles with v.in.ogr,
when I run the command:
v.in.ogr dsn=/home/vincent/Longmen_Shan-data/Geologie/geologic_age.shp
output=geologie layer=geologic_age min_area=0.0001 snap=0.001 -o
I am getting the following error message:
DBMI-DBF driver error:
Column 'GLG' already exists (duplicate name)
Cannot create table.
Error in db_execute_immediate()
ERROR: Cannot create table: create table geologie (cat integer, AREA double
precision, GLG varchar ( 5 ), GLG varchar ( 5 ), DESCRIPTIO varchar
( 32 ))
It seems that there is a problem with my .dbf file but I don't know what.
Thanks in advance,
Vincent.

Hi!
I just had a similar problem related to DBF file contents. I found that open
office can open the DBF, edit it, and save it again.
Not ideal, but it would be rather simple to remove a field.
Cheers!

If you have access to ArcGIS then try opening the file there
and renaming the second GLG column to something different
(i.e. GLG2).
If you don't then maybe it is possible to somehow use ogrtools
to change the column name, but I'm not really familiar enough with it.
At the least you can go:
> ogrinfo -al -summary
and this should allow you to confirm the problem is two attributes
of the same name.
Hope this of some help,
Joel

You can also use OpenOffice for this:
View -> Data
* Sources -> select your data source (probably "Data source 1")
* Tables
* your table 'whatever_name'
* click right mouse button on table
-> Edit table
-> modify column(s)
-> Save the table.
* 'Exit' from OpenOffice.
Or you can probably also use db.execute, add a new column,
copy over the values from the other column, then remove this column (untested).
