[GRASS-user] wxPython in 6.3.0RC4?
Hi list, I've just installed the RC4 version, but wxgrass is not installed. I was wondering why then the release news mentions that "Additionally, this release debuts a new graphical GIS manager and menu system, while an improved version of the old GUI display manager has been retained for legacy support." Is the SVN version the one that has wxgrass in it? Was some kind of flag missing when I compiled grass? Best, Jaime - ¡Capacidad ilimitada de almacenamiento en tu correo!

Error #4 (NVIZ) is a consequence of this; OGSF fails to build due to FFMPEG issues, and NVIZ fails because OGSF is missing. As Michael points out, (2) and (3) are because you need to use --with-python (which requires SWIG) to build the wxPython digitising module. -- Glynn Clements <[EMAIL PROTECTED]> ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
Re: [GRASS-user] How to list all unique pixel values (of a raster) covered by polygons (areas) for each polygon separately(?)
Giovanni, thank you for your proposal. The link to the FAQ (the one that Jose provided) looks like a solution. But your idea is clever as well and I had a similar way in my mind. If I got it correct you suggest: 1. VectorTargetAreas ~~~v.to.rast (based on unique attribute like cat or FID~~~> RasterTargetAreas (all pixels of a "TargetArea" have now the same value 2.MASK out everything besides the "TargetAreas" ---looping to create as many MASKS as the the number of the "TargetAreas" 3. For each MASK run r.stats 4 (I would also like to have) add the output list(s) as a new table (column pixval) into the initial VectorTargetAreas (with db.connect, db.addcol, etc). Let's say for a polygons which covers 20 pixels it would be like: FID - cat - pixval 1- 1 -200 2- 1 -198 3- 1 -234 ..- .. - . 20 - 1 -765 Is it possible to put all this together? r.stats and output into a new column (pixval) On Thu, 2008-01-17 at 18:25 +0100, G.

Thanks! this is probably not much help, but a uniform distribution of input points is the best solution. it doesn't deal well with a high density of points right next to a low density area. for your current data try increasing npmin, segmax. r.surf.nnbathy from the wiki addons page is another option.

Re: [GRASS-user] problems starting wxPython gui using wingrass
If the digitizing module needs SWIG to compile, I suggest that the developers of the digitizing module do the SWIG processing and have those preprocessed files in the source, so that endusers compiling GRASS don't have to worry about yet another developer-only extra. I don't know how common or "standard" SWIG is on other systems, but it's not part of the older OSX developer tools (Xcode 2) still in wide use, though it was added to the Leopard developer tools (Xcode 3). GDAL and MapServer do this. Qgis does this at least for the release source. On Jan 17, 2008, at 11:55 AM, Michael Barton wrote: I have no idea about the others.

Re: [GRASS-user] How to list all unique pixel values (of a raster) covered by polygons (areas) for each polygon separately(?)
Just a rapid idea. You could make just one rasterized map of your polygons and then insert in a loop this, giving each pixel a unique category value: r.mapcalc "MASK = if(raster=$i,1,null())" with $1 the cat value (deriving from you original polygon) and then run r.stats, which will work only for the un-masked pixels. I don't have time to try this method, hope it helps.

Salut Jose! This is what I am doing... and I only have 7 polygons - so it is ok. But if I have 50 polygons... I am not so sure how to script it to get (finally) a table with all pixels for each unique polygon for 2 different images of the same location (for raster MODIS year 2006 and then another of the same area MODIS 2007!). I want to run a regression with the pixel values... (pairs of 2006 and 2007 values). Thank you, Nikos.

[GRASS-user] How to list all unique pixel values (of a raster) covered by polygons (areas) for each polygon separately(?)
I tried to make it clear in the title... but I am not sure that it's easy to understand. Using v.rast.stats I get uni-variate statistics from a raster (in my case a MODIS image with 250m pixel size) based on polygons I digitised manually (areas). How can I get listed all unique pixel values enclosed in each of the polygons I digitised (and for which the univ. stats are calculated)? Need them for further statistical analysis... There must be a way to do this instead of creating unique raster(s) for each polygon and using r.stats... ! ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

[GRASS-user] Problem with r.out.ascii
Hi list Im trying to use the r.out.ascii command but it fails Got an existing mapset, with some elevation rasters in it (.tiff converted in grass raster) I'd like to extract the xyz values of a DEM to txt file I use this syntax in the grass shell: [code] r.out.ascii input=mnt output=testmnt.txt [/code] testmnt.txt is created and the header is written,but the x,y,z values are missing, only stars appear in it, like this: [code] north: 2787570 south: 1546950 east: 1284500 west: -47544.1 rows: 931 cols: 999 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * [/code] Is anybody understands what happens?

Within Illustrator maybe you can build a script that adds intermediate points to curves (don't really remember, but it sounds like 'densify paths', or 'add anchor points'), attended that vertices will be recognized when imported Vincent Le jeudi 17 janvier 2008 à 09:03 +0100, Andreas Neumann a écrit : > ok, the problems are with the curves. > > The ogr2ogr tool has a converter from Interlis to other ogrformats. > Interlis supports arcs (defined by three points).

[GRASS-user] error in gis.m georectify tool
Hi Markus,
I'm trying to use the new georectify tool in GRASS 6.3 but I have a
little problem.
I create my imagery group (new) with the four satellite images of
imagery60 dataset (spot.comp, spot.ms1, spot.ms.2 and spot.ms.3).
Then I open a mapset in spearfish60 and I set my region on "roads"
vector extension.
Then I Select /*Georectify*/ from the /*File*/ menu and I select the
location/mapset (imagery60/PERMANENT) of the map to georectify
(spot.comp), the /image group/ (new) of the map to georectify, and a map
to use for marking GCPs (roads).
When I click on "Start georectifying" this does'nt open the special map
display and I have this error message:
missing "
missing "
while compiling
"Gm::errmsg $error ["Error setting region]
"
("if" then script line 2)
while compiling
"if {[catch {close $input} error]} {
Gm::errmsg $error ["Error setting region]
}"
("if" then script line 10)
while compiling
"if {![catch {open [concat "|g.region" "-up" $args "2> $devnull"] r}
input]} {
while {[gets $input line] >= 0} {
set key [string trim [linde..."
(compiling body of proc "GRMap::zoom_gregion", line 11)
invoked from within
"GRMap::zoom_gregion"

invoked from within
"uplevel \#0 $cmd"

Any idea about this?
Thank you

Re: [GRASS-user] Vector drawings in PDF -> converting them
ok, the problems are with the curves. The ogr2ogr tool has a converter from Interlis to other ogrformats. Interlis supports arcs (defined by three points). They also calculate new vertices along the arcs to be compatible to other formats that don't support curves. One can define how many Every SVG viewer has code on how to display curves (arcs, quadratic and cubic spline curves). But I don't know if you can dig up and work with that code directly. Many of them probably forward their drawing commands to underlying graphics libraries like Cairo, AGG, OpenVG, Java2D, etc. As you said, you might also want to ask the Batik developers on the Batik list.
