[GRASS-user] html page for an addon script
Dear Grass users, my problem is concerning the html page which we can create with scripts. I created a shell script (called m.dispolyg) and his html page for helping user (m.dispolyg.html). I put my shell script and the html file in the following directory: usr/lib/grass/addons and in my /$HOME/$USER/.bashrc I put these two lines: GRASS_ADDON_PATH=/usr/lib/grass/addons export GRASS_ADDON_PATH With this I can launch my script in grass but when I write g.manual m.dispolyg I've got the following error: ERROR: No HTML manual page entry for m.dispolyg. Should I put the m.dispolyg.html file in this directory or in another directory like usr/share/doc/grass-doc/html ? I run grass 6.3. on ubuntu 8.10, grass is in the following directory: /usr/lib/grass Thanks for any help Michael Rabotin -- * Michaël Rabotin Ingénieur d'étude en géomatique Laboratoire d'étude des Interactions entre Sol, Agrosystème et Hydrosystème UMR LISAH SupAgro-INRA-IRD Bat. 24 2 place Viala 34060 Montpellier cedex 1 FRANCE Téléphone : 33 (0)4 99 61 23 85 Secrétariat : 33 (0)4 99 61 22 61 Fax : 33 (0)4 67 63 26 14 E-mail : rabo...@supagro.inra.fr * ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
[GRASS-user] [GRASSLIST:1217] m.cogo in -r mode
Good morning from Toulouse, I have to make some calculations by bearing sector and my idea is to use m.cogo. I have vector points and I wanted to use m.cogo with -r option to come back to bearing/distance and then make some averages on the bearing. However, it seems that I'm not using it correctly since it is not producing the expected result for a test case : for example in an x,y coordinate system, when I run echo 'N 00:00:00 W 10' | m.cogo it returns 0.00 10.00 this is OK However echo '10 0' | m.cogo -r returns N 90:0:0.000 E 3.162278 while I would have expected the distance to be 10 Can someone help me to see my mistake ? best regards, Grégoire begin:vcard fn;quoted-printable:Gr=C3=A9goire Pigeon n;quoted-printable:Pigeon;Gr=C3=A9goire org;quoted-printable:METEO FRANCE;Centre National de Recherches M=C3=A9t=C3=A9orologiques adr:;;42, av.

[GRASS-user] Calculating eigen values and % variance explained after PCA analysis
Dear Colleagues, I have run a PCA on a five band data set consisting of three optical bands, a canopy height model and lidar intensity measures. Output from the i.pca module only provides the eigen vectors. I would like to calculate the eigen values and % variance explained by each component in my PCA analysis. Is it possible to calculate the eigen values and % variance explained using GRASS or should I use something like R? I am using version 6.3 on ubuntu hardy heron. Many thanks for your help.

I've notice that i.group window has been changed: shouldn't “Name of imagery sub-group” and “Name of the raster map(s) to include in group” be under the Required tab rather than Optional? 'group=name' is the only required option. you can list maps in the group without adding any, so the subgroup and input raster maps are not needed sometimes. also subgroup really is optional. btw (for better or worse) those required/optional groupings happen automatically based on module requirements. I'm not really a fan of that but others think it's a useful feature. shrug I see what you're saying (don't get me wrong, I don't want to criticize in a “bad” way, it's because maybe you receive a lot of feedbacks about other parts and this module is not so usedI haven't seen so many Remote Sensing questions lately...that's why). polite and researched feedback is always welcome! once you are comfortable that an issue is really a bug, please file a ticket, one for each issue. if just left in the mailing list it'll more easily be forgotten in the noise. -Supervised- I couldn't figure out how to make it work. ...but nothing more than that. Shouldn't I be prompted to a display where I can draw my region of interest? (I don't know, maybe I'm expecting something that it's not supposed to be). for sure old xmon based interactive monitors are gone for wxPy on Windows. not sure about what to expect from these modules, but supervised says to me some sort of map interaction is required... GUI: Imagery → Classify image → Interactive input for supervised classification (requires Xterm) it doesn't just need an terminal window for the text based menu data entry, in needs an Xmonitor as well, which is unavailable in the native MS Windows build. a blank Monitor display and a new shell appear and nothing else. we need a better sorry, won't work on MS Windows (so far) error message there. Is the wxPyhton GUI supposed to be run only on Windows? I guess not..right? http://svn.osgeo.org/grass/grass/trunk/gui/wxpython/README because I'm runnig this magic on Lenny ;-) (I actually got the 6.4 version from Sid repository). Are all of the GUI issues due to this http://grass.osgeo.org/wiki/WxPython-based_GUI_for_GRASS#Imagery_tools (Status: development not started yet) perhaps better stated as redevelopment not started in earnest yet, Some behind-the-scenes code has been prepared, but not much. Volunteers welcome! I would if I could but I don't have the required knowledge (I planned to learn a bit of Pyhton though, so maybe one of these days). Hamish Since I'm here I'll use the same post to ask you another thing: is there any way in GRASS to link different map displays and have a brushing (update while dragging) or even a static d.what.rast?
