Re: [GRASS-user] GRASS'c Python core function to use as g.mlist
Hello Ricardo
Thanks for your feedback but the problem is that mapset cannot be used as
input.
Because I got this error:
p=grass.mlist_grouped ('rast', pattern=pattern,
mapset='PERMANENT')
TypeError: mlist_grouped() got an unexpected keyword
argument 'mapset'.
If I avoid using mapset I get a dictionary variable in which, each entry is
the list of rasters for each MAPSET.
Am I doing something wrong?
Thanks

Hi Jenny
Long story short: use your command like this (note the asterisk on the
'pattern' variable):
# python code
p=grass.mlist_grouped ('rast', pattern='output*', mapset='Mapping')
I am using the Ipython shell to script grass. It has a cool feature,
that if you type the name of a function followed by two question
marks, you can see the source code of the function (as long as it is
coded in python itself).
So, in doing:
grass.mlist_grouped??
It is possible to see that the mlist_grouped function is internally
calling the 'g.mlist' command with only the 'm' flag.
Reading the documentation for the g.mlist command [1], I realize that,
without using the -r or -e flags, this command accepts wildcards[2] as
the 'pattern' string. The asterisk (*) is the wildcard character for
substituting for any zero or more characters. So, in order to get a
string that starts with 'output' and after that can have anything, you
just type 'output*'

Hi Markus Let me just say that, according to snapshots, you have done a great job for new WxGeorrect :) So, my only question now is (at least, please can anyone answer this: My active mapset shall be which one? the one where I have my reference images (already georrectified) or mapset where I have my not-georreferenced images)? The active location is the target location with a mapset with your reference images (indicated by the very first question of the georectifier where you have to specify the source and not the target location). My question was not related with Lcoation (because both maps (not-georreference and georreferenced) are in the same Location but in different mapsets In my example: Mapset:Local: not-georreference and to be georreferenced (How do you call this?) Mapset: Global: georreferenced (how do you call this?) In the first panel it's asked about Source Location and source Mapset. You mean that here I shall define where is my not-georreferenced image? In this case mapset:Local? Second panel asks for a group of images to be goerrectified. Third asks for an image to be displayed. in this case is a georreferenced or not-georreferenced image? So, in the normal Map diSplay window I will put an already georreferenced image right? in this case from Mapset Global? Thanks and sorry for such a dumb questions Jenny Source and target location can be identical.

Using gdalwarp you don't have to specify the source coordinate system, *if* the originals have the correct projection defined in their headers. For Landsat images, this is most likely the case, so you should be able to get away with just setting the -t_srs option of gdalwarp and each tile will be re-projected to the WGS84 geographic CRS.

Re: [GRASS-user] Importing Landsat images with different coordinates
Greetings Firman, but imagine that I have rasters in UTM for differente zones (e.g. huge countries like USA, etc). How can I produce an automatic importing tool that uses gdalwarp to project an image to WGS84 and import to GRASS?

[GRASS-user] GRASS Script for importing data with different source_coordinates/projection
Greetings This almost a follow-up from a previous message that I sent regarding Landsat-7 image importing. I need to develop a script to import images from multi-SOURCE_COORDINATE_SYSTEM to defined target_COORDINATE_SYSTEM (WGS84). Since my input images come from different UTM zones it won't be possible to import images using a pre-defined gdalwarp command to convert coordinate/projection systems, since source coordinates are more than one. Firman made suggestion of using a GRASS Script to read header and get coordinate system. Has anyone developed something similar to this? Thyank you Best regards, Jenny ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
Re: [GRASS-user] Importing Landsat images with different coordinates
Greetings Thanks It really worked but now I have one particualr question: I need to have an automatic proceeding but, in this case my input images are not in the same coordinate system (e.g. different UTM Zones). Can I apply this methdology without defining source_coordinate system?

Could anyone explain me (briefly ) the steps to import this images? Thanks Jenny Dear Jenny, If your images are in TIFF, you can convert the coordinate system to the one that you have, with gdalwarp. As an example, if my coordinate system is UTM Zone 48S (32748) and my data is in lat-long (4326), I will use gdalwarp command like this: gdalwarp -t_srs EPSG:32748 -s_srs EPSG:4326 source.tif target.tif Cheers, Firman Hadi Center for Remote Sensing - ITB Jl.

Re: [GRASS-user] Compare GRASS versions
Thanks Markus So the main reason for still supporting GRASS 6.4 is its stability right? For instance, do you plan to launch 6.5 as a end-product? Thanks Jenny 6.4 and 6.5 are rather close, 7 is starting to deviate. What I need to know is if there is any document that compares and assesses these 3 versions in order to characterizes each one. To my knowledge there is none. The Wiki would be the right place to start it. For instance GRASS6.5 is able to have dynamic wxpython scripts (e.g. v.krige) that is an interesting funcionality. Yes - but for stability reasons (in case you need it in production), you may consider 6.4. If functionality is missing and available in later versions, it could be discussed to backport it for 6.4.1 if not too complicated. Otherwise, take the next higher version number.

re: [GRASS-user] Gorreferencing using GRASS
Greetings This was the right email at the right time. I was just doing some georreferencing and I have one or two questions regarding Martin video (awesome, by the way): 1- Right in the beggining, you have a raster, named mrizka, displayed in Display window1. I want to know: - How did you put the grid; - What is the purpose of this image? Because it is empty... It's totally blank 2- The group you create is the group of images you want to georrectify right? 3- the last panel, before, georrectification, regards image to display for GCP creatioN. This means what? This image is the one that I want to georrectify or the one that is already rectified? Because when it's opened, it already displays a grid and points/numbers. 4- XY are coordinates from not-georreferenced images and E/N are form the Georreferenced images right? This may sound lke dumb questions but I'm not use to this proceeding Thank you for your help Jenny ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

[GRASS-user] Can't initialize wxpython GRASS6.4
Greetings I have just installed in my old laptop a Ubuntu Karmic version of GRASS (6.4). I know it's not new but I'm getting an ODD error that it's not suppose to happen. I have placed nc_spm_08 data in /home/jenny/data folder and everytime I do sudo grass64 -wxpython When it's open GRASS GIS layer Manager I get an error window stating: Unable to get current geographic extent. Force quiting wxGUI. Please run manually g.region to fix the problem. This is weird because it's suppose to work right? Any ideas?
