Re: [GRASS-user] How to obtain list of all raster maps
Dear Mr. Neteler & Mr. Silver,
Thank you both for your responses. Yes both of the methods seems to be
working.
Also, while going through some other documentation i discovered another
metho. We can output the entire data into a text file by including an
output argument in the command. (*g.list type='raster' mapset='.'
output='rasterNames.txt' )*
Problem solved... Thanks
Regards,
Bharath

[GRASS-user] How to obtain list of all raster maps
Hello, I have a list of raster files inside a mapset that I need to interpolate to a different size. I am aware of the command *g.list type='raster' mapset='.'* and its equivalent python version. But the command prints the filenames out on screen instead of returning it as a list (I am talking wrt python API). Am I missing something or is there any workaround for this? Thank you.

Re: [GRASS-user] How to obtain list of all raster maps
You can use the grass.script module 'read_command' to save the output of
commands. i.e.
In [1]: import grass.script as gscript
In [2]: rast_list = gscript.read_command('g.list', type='rast',
mapset="shkharia").strip().split('\n')
In [3]: type(rast_list)
Out[4]: list
In [5]: rast_list
Out[6]: ['aspect_4m', 'dtm_08_4m', 'dtm_4m', 'geomorph', 'shade_4m',
'slope_4m']
Typically the output will be a string (or dict), but calling split('\n')
breaks it into a list.
