06:29:25 arkygeek: hello folks :- )
06:29:39 arkygeek: I have a csv file froma total station that I would like to bring into grass.
06:29:53 arkygeek: anybody here done this before?
06:45:55 : <_wolf_> sorry I haven't
06:46:02 : <_wolf_> is this a vector file?
06:46:05 arkygeek: yes
06:46:10 arkygeek: points only x,y,z
06:46:16 : <_wolf_> v.in.ascii is your friend
06:46:23 arkygeek: i just can't make grass realize there is geometry there :s
06:46:26 : <_wolf_> is it points data?
06:46:30 arkygeek: hrmmm
06:46:45 arkygeek: yes
06:47:00 : <_wolf_> is it delimited with ,?
06:47:07 arkygeek: yes
06:47:37 : <_wolf_> hang on
06:48:03 : <_wolf_> is it 2d or 3d data?
06:48:10 : <_wolf_> any additionale data?
06:48:39 arkygeek: 3d
06:48:42 arkygeek: yes, some
06:48:51 arkygeek: 713,1057.726,1189.542,1010.977,210,,Draw 2002_019 Pt. 1
06:48:55 arkygeek: ^ for example
06:49:25 arkygeek: ID, x, y, z, feature, note, name
06:51:51 : <_wolf_> Try this:
06:51:52 : <_wolf_> v.in.ascii input=yourfile output=yourvectormap fs=, columns="cat int,x double, y double, z double, feature int, note varchar( 200 ), name varchar( 200 )" cat=1 x=2 y=3 z=4
06:52:21 arkygeek: trying
06:52:22 : <_wolf_> add skip=1 if you want to skip header lines
06:52:38 : <_wolf_> see http://grass.osgeo.org/grass64/manuals/html64_user/v.in.ascii.html for more detailed info
06:52:39 sigq: Title: GRASS GIS manual: v.in.ascii ( at grass.osgeo.org )
06:53:28 arkygeek: ERROR: Unparsable latitude value in column <2>: 1189.542
06:53:58 arkygeek: same I was getting before
06:54:28 : <_wolf_> so your location is is lat-long
06:54:57 : <_wolf_> what projection is that csv file for?
06:55:06 arkygeek: it is, but i don't know what the csv projection is
06:55:12 arkygeek: drat
06:55:36 : <_wolf_> it looks like projected coordinates
06:56:02 arkygeek: adnan says it is turkey's national grid system
06:56:05 : <_wolf_> you can create a new xy location an import it there, if it will help you to determine the projection info
06:56:10 : <_wolf_> ok
06:56:20 : <_wolf_> then you need to create a location for that
06:56:27 arkygeek: ok.....
06:56:41 arkygeek: heh .... need to think how to do that now :-P
06:57:12 : <_wolf_> do you know the info? or like an EPSG code for it?
06:57:24 arkygeek: looking
06:57:29 : <_wolf_> what version of GRASS are you using?
06:57:50 : <_wolf_> if 6.3 or newer the gui is your friend
06:58:04 : <_wolf_> you can create a new location based on an epsg code from that
06:58:40 arkygeek: 6.4 in osx
06:58:48 arkygeek: looking in qgis.... THAT is easy heh
07:01:18 : <_wolf_> no I meant the GRASS GUI
07:01:43 : <_wolf_> there is a location wizard which comes up when you launch grass as GRASS64 -gui
07:01:57 arkygeek: ok I will look at that
07:02:55 : <_wolf_> it will ask you for a name for the location and the EPSG code, should be visible in the gui that pops up. Sorry I cant be more specific, but I've jusr reinstalled my computer and I haven't set up GRASS yet.. :S
07:03:00 arkygeek: how do io start that wizard from the cli
07:03:10 arkygeek: it is starting in text mode
07:03:24 arkygeek: ahhh
07:03:25 arkygeek: np
07:03:40 : <_wolf_> try -gui or -wxgui flag when you start GRASS
07:05:43 arkygeek: doesnt seem to make a difference ... ????
07:09:03 arkygeek: got it
07:12:05 arkygeek: _wolf_: http://spatialnews.geocomm.com/community/lists/viewmessage.phtml?id=8806
07:12:06 sigq: Title: Spatial News Re: GISList: Turkish coordinate system to geographic ( long/lat ) coordinates - cross posted Archives \n'+ ' ( at spatialnews.geocomm.com )
07:14:38 arkygeek: i have no idea how to do that
07:21:31 sneezewort: What do I need to do on a debian system to be able to import grass in python?
07:21:46 : <_wolf_> arkygeek: hang on
07:23:48 : <_wolf_> akygeek see here for the EPSG code to use: http://www.epsg-registry.org/
07:23:49 sigq: Title: EPSG Geodetic Parameter Registry ( at www.epsg-registry.org )
07:24:05 : <_wolf_> type Turkey in area and you'll get a list
07:24:32 arkygeek: _wolf_: got it
07:24:40 arkygeek: ok, but i need hlp i think lol
07:24:48 arkygeek: they are nominal coordinates
07:25:13 arkygeek: 0,0,0 is at 1020.3 asl
07:25:38 : <_wolf_> yeah tose coords don't look like Transverse merc ( which basically what they use )
07:25:40 arkygeek: utm zone 36N 484844E 4168967N
07:25:53 : <_wolf_> try an XY location
07:26:03 arkygeek: oh, that was assigned 1000,1000 I guess
07:26:03 : <_wolf_> what do you need to do with those points?
07:26:33 arkygeek: plot them in 3d, do cluster analysis
07:26:49 arkygeek: examine cluster in z-ranges
07:27:15 : <_wolf_> the problem with xy is that it might be inaccurate, but in your case maybe that is all you can do
07:27:45 : <_wolf_> try it out and if the results look very odd send email to the grass-users list
07:28:16 arkygeek: "Being one of the the more elevated features in the Konya polain, the larger east mound has a triangulation point on its summit, the height of which is marked on the 1:25000 map as 1020.3 m asl some 16 m above the plain.
07:28:50 arkygeek: the utm zone 36n coordinates for this datum were 484844e 4168967n
07:29:47 arkygeek: the datum point from which the survey originated was assigned the nominal coordinates os 1000mE 1000m N in the site grid which was intended to encompass tboth the east and west mounds.
07:30:32 : <_wolf_> I'd use XY since it is not a very large area
07:31:31 : <_wolf_> you can then maybe use v.transform to transform them into a UTM location
07:31:34 : <_wolf_> http://grass.osgeo.org/grass64/manuals/html64_user/v.transform.html
07:31:35 sigq: Title: GRASS GIS manual: v.transform ( at grass.osgeo.org )
07:31:56 : <_wolf_> but I've got to go for now
07:32:28 : <_wolf_> check back with me later and let me know how it goes. I've never used v.transform so I don't really have any experience...
07:33:05 cgs_bob: arkygeek: btw, as another way to get your csv data into a gis format, you might also like to try this: http://www.gdal.org/ogr/drv_csv.html
07:33:06 sigq: Title: Comma Separated Value ( .csv ) ( at www.gdal.org )
07:34:20 sneezewort: Is it possible to use grass as a python module?
07:34:51 sneezewort: Is there a grass python module?
07:38:15 cgs_bob: sneezewort: yup...you can find it in grass 6.5s etc/python directory. and if you are working with grass 7.0, many of the grass commands are written in python.
07:39:40 sneezewort: Thanks cgs_bob
07:41:03 cgs_bob: sneezewort: you're welcome
08:05:39 simgislab: hi all, can someone check if r.digit is present in 6.4? Can't find it ( installed with osgeo4w ).

18:53:36 jpablo: Hi there... How can I start the GUI of grass?... I tried with grass -gui, but always is command line way
18:59:19 cgs_bob_: hi jpablo. what OS are you using?
18:59:29 jpablo: cgs_bob_, Debian GNU/Linux
19:02:02 cgs_bob_: so when you start grass by typing grass, you do not see the startup screen? have you also tried grass65 or grass70 ?
19:03:54 jpablo: the monday I was working with grass 6.2.3, but I update the program at 6.3... and after I cant see the gui again
19:05:21 jpablo: cgs_bob_, are you using a OS Linux too?
19:05:30 cgs_bob_: I see. so you just get the curses interface. what happens when you use gis.m?
19:06:06 cgs_bob_: yes...I'm on Ubuntu which is a Debian derivative
19:07:27 jpablo: cgs_bob_, http://paste.debian.net/36684/
19:07:28 sigq: Title: #debian.de Pastezone ( at paste.debian.net )
19:07:39 cgs_bob_: btw, you might like to upgrade to grass 6.4...many commands have a big performance boost
19:08:59 jpablo: cgs_bob_, I tried delete grass for reinstall, but grass has routes yet
19:09:27 cgs_bob_: interesting...see what happens when you do this: export DISPLAY=:0.0
19:09:34 cgs_bob_: and then restart grass
19:12:05 jpablo: export DISPLAY=:0.0 dont said any err..
19:12:19 jpablo: and grass is only command line yet
19:12:30 jpablo: ( excuseme my bad english ) cgs_bob_
19:13:14 cgs_bob_: when you start grass do you get a message like this: http://paste.debian.net/36685/
19:13:16 sigq: Title: #debian.de Pastezone ( at paste.debian.net )
19:14:39 jpablo: yes cgs_bob_
19:14:42 jpablo: but....
19:14:57 jpablo: only when I tried start like root
19:16:29 cgs_bob_: so I guess DISPLAY is not set when you start grass under root.
19:17:26 cgs_bob_: just curious...what is your native language?
19:19:14 jpablo: Spanish
19:19:38 jpablo: cgs_bob_, look please
19:19:41 jpablo: http://img156.imageshack.us/img156/7374/pantallazoquf.png
19:20:03 jpablo: http://img35.imageshack.us/img35/6651/pantallazo1p.png
19:20:39 jpablo: cgs_bob_, The first image is like root user and the second like user without privileges
19:23:06 cgs_bob_: I do know that there are a lot of Spanish speakers on the grass user mail list. you might like to join. info at http://grass.osgeo.org/community/support.php
19:23:08 sigq: Title: GRASS GIS: Support and Mailing Lists ( at grass.osgeo.org )
19:24:03 jpablo: :(
19:24:18 cgs_bob_: I'd like to help you more, but my 3year old girl needs my attention
19:24:29 jpablo: the last question please
19:24:34 cgs_bob_: ok
19:25:04 jpablo: what I should make when the system showme http://paste.debian.net/36685/
19:25:06 sigq: Title: #debian.de Pastezone ( at paste.debian.net )
19:26:30 cgs_bob_: that happens when the DISPLAY environment is not set. btw, I would not recommend running X as root
19:27:50 jpablo: Ok... Can I meet you tomorrow?
19:28:07 jpablo: ( excuseme for my terrible english ) : )
19:28:10 cgs_bob_: you might want to search the grass user mail list for a similar problem. take a look at this: http://www.mail-archive.com/grass-user@lists.osgeo.org/
19:28:11 sigq: Title: grass-user ( at www.mail-archive.com )
19:28:36 jpablo: ok thanks for all cgs_bob_ .: )
19:29:24 cgs_bob_: you're welcome. and if you do join the mail list you will get a whole lot of help from the grass community
19:30:06 jpablo: ok... I will tell you ... what is my luck with this problem
19:31:14 cgs_bob_: I think it is easily solved. and if you upgrade to the current version of grass you might not have any problems : )
19:31:45 jpablo: what version?
19:31:58 cgs_bob_: grass 6.4
19:32:19 jpablo: Ok thanks again
19:32:59 cgs_bob_: take a look at http://grass.osgeo.org/download/index.php
19:33:00 sigq: Title: GRASS GIS: Download ( at grass.osgeo.org )
19:33:34 cgs_bob_: glad to help. good luck solving your problem
19:33:57 jpablo: Grass Rulz!!
19:34:35 cgs_bob_: yes it does...see ya later!
