Re: [GRASS-user] passing output from GRASS to R.
Thanks for both, Markus and Roger Bivand. Cheers milton 2009/5/5 Roger Bivand roger.biv...@nhh.no From spgrass6 0.6-*, and after installing the R XML package (off CRAN but installs automatically from Prof. Ripley's extra Windows repository if you are on Windows), you can use: rasterfiles - execGRASS(g.mlist, parameters=list(type=rast, pattern=*ele*), intern=TRUE) (here from spearfish, which has *ele* rasters in PERMANENT). Do: parseGRASS(g.mlist) to see the flags and parameters. As Markus pointed out, intern=TRUE is the key argument, to get the output of the GRASS command back into the R workspace. There are issues with regard to quoting between platforms for a few GRASS commands, but most things now work. I tried this on MSYS Windows native 6.4.0 RC4.

Re: [GRASS-user] Creating LiDAR first pulse vector map
Jack, usually lidar data I have seen so far, have also information on pulse other then X Y Z Intensity Maybe you could check if you have couples of points with really close coordinates and different Z. If it is, I guess your file is listing one point for each returned pulse... and in this case you should make some scripting to extract the first and last pulse... Maxi Jack Lonsdale wrote: I am still fighting with the LiDAR tools, but I feel like I am close... I thought I had sorted the v.lidar.growing problem as it appears to run when using sqlite backend. But the resulting output was only a small portion of the output? For v.lidar.growing, is there any special way to create the first pulse vector map? I feel this may be where my problem comes from. (Currently I was just using the raw data from the lidar text file which includes X Y Z and intensity readings for all points.) Thanks -- Dr. Eng.

Re: [GRASS-user] python commands on grass.
Hi,
2009/5/5 Milton Cezar Ribeiro miltinho.astrona...@gmail.com:
is there a way of I know the commands available on python grass library?
grass.py is located in
lib/python
e.g.
https://svn.osgeo.org/grass/grass/trunk/lib/python/
It's best documentation :-)
Meanwhile, I can run g.list with the command bellow, but I can't
deal with the name of each of my raster map. In fact I receive the
same output as in gis.m console, but I would like only receive a list of
maps as output.
rasterfiles = grass.read_command('g.list',type='rast')
use
grass.mlist_grouped(type = 'rast')

Checking the codes available at
https://svn.osgeo.org/grass/grass/trunk/script
(thanks Martin) I saw the following commands:
grass.read_command
grass.parse_key_val
grass.run_command
grass.message
grass.fatal
By the way, how can I know the methods / parameters for each command?

[GRASS-user] Re: [GRASS-dev] Seeking old version
Markus, for what its worth, I have a CDROM snapshot (?) dating from 1998, featuring: --- So, what is new in GRASS 4.2.1 (22. September 1998) and what is the difference to BAYLOR´s version? The major point is a lot of bugfixing. There is still no floating point in raster files, but we all hope for GRASS 5.0 in summer 1998. The difference between my package and the original Baylors GRASS 4.2 are - elimination of errors in several modules (read history file) - changed r.le 2.1 to version 2.2 - cleaning the package structure - addition of lots of modules (see below in src.alpha). - tcltkgrass - the new graphical user interface is added -- Does this help ?
