[GRASS-user] Using GRASS 6 without starting it (Python)

GRASS GRASS user
,

Hi,

I have been trying to use GRASS without opening it explicitly following the instructions from here: http://grasswiki.osgeo.org/wiki/Working_with_GRASS_without_starting_it_explicitly#Python:_GRASS_GIS_6

Since I am on Windows, I had to adapt it a bit (and I tried many, many variations). The most likely

import os
import sys
location = “AZ”
mapset = “AZMAP”
gisbase = os.environ[‘GISBASE’] = “C:/Program Files/QGIS Valmiera/apps/grass/grass-6.4.3”
sys.path.append(os.path.join(os.environ[‘GISBASE’], “etc”, “python”))
gisdbase = os.path.join(os.getenv(‘APPDATA’, ‘GRASS6/grassrc6’))
import grass.script as grass
import grass.script.setup as gsetup
gsetup.init(gisbase, gisdbase, location, mapset)

What I get when I run these lines is the line below:

‘c:\users\pcamargo\appdata\local\temp\tmp7wvogg’

The content of this file is

GISDBASE: C:/Users/pcamargo/AppData/Roaming/GRASS6/grassrc6
LOCATION_NAME: AZ
MAPSET: AZMAP

While it should be getting the contents from the file at C:\Users\pcamargo\AppData\Roaming\GRASS6\grassrc6

What am I doing wrong?

Thanks,

Pedro

He Pedro

Please try to specific your GISDBASE location as the code showing below;

import os
import sys

gisbase = os.environ[‘GISBASE’] = “C:/Program Files/QGIS Valmiera/apps/grass/grass-6.4.3”
sys.path.append(os.path.join(os.environ[‘GISBASE’], “etc”, “python”))
gisdbase = os.path.join(os.getenv(‘APPDATA’, ‘GRASS6/grassrc6’))

location = “AZ”
gisdbase = “C:/Users/pcamargo/AppData/Roaming/GRASS6/grassrc6”
mapset = “AZMAP”

import grass.script as grass
import grass.script.setup as gsetup
gsetup.init(gisbase, gisdbase, location, mapset)

Best,

Sittichai

Hi Sittichai,

The location of the database is J:\MY_PROJECT\GRASS

Is that what you wanted to know?

Thanks,

Pedro

So you need to set the GISDBASE variable to the above. NOT as you set in your first mail:

Hi Sittichai and Micha,

I just came back from a conference, thus back to this issue.

I tried many configurations for the code, including the following

gisdbase = os.path.join(os.getenv(‘APPDATA’, ‘grassdata’))

and

gisdbase = os.path.join(‘J:/MY_PROJECT/GRASS/’)

and

gisdbase=‘J:\MY_PROJECT\GRASS’

and

gisdbase = os.path.join(os.getenv(‘APPDATA’)+ “/GRASS6/grassrc6”)

For all these, the output was the same, and created a file in the temp folder as below.

c:\users\pedro\appdata\local\temp\tmprdjnow
-1073741515

Any other suggestions?

Thanks a lot,

Pedro

I’m not an expert in python, but I think you need something like: gisdbase = os.path.join(“J:/”,“MY_PROJECT”,“GRASS”) Then, of course, run the grass.init function
