[GRASS-user] readVECT6 in R under GRASS

[GRASS-user] Re: readVECT6 in R under GRASS
You need to provide a lot more information, including the messages displayed when spgrass6 (and possibly rdgal) are loaded, and the output of sessionInfo(). These will tell us which versions you are using. Then also run: execGRASS(g.list, parameters=list(type=vect)) to check that the vector object you think that you have is actually visible. It may be in a mapset that is not on your search path. Roger Salvatore Mellino wrote: Hi, I'm trying to open a vector file (points) in GRASS with R.

[GRASS-user] ASTER GDEM Version 2 --- filtering and smoothing
Hello, dear GRASS users. A few words about new ASTER GDEM version 2https://lpdaac.usgs.gov/about/news_archive/monday_october_17_2011 . As was explored, this DEM could be also rather well filtered and smoothed with the Sun's denoising algorithmhttp://personalpages.manchester.ac.uk/staff/neil.mitchell/mdenoise/(using GDAL and free / open source program mdenoise). Also there is GRASS add-on r.denoise http://grass.osgeo.org/wiki/GRASS_AddOns#r.denoise. Experiments showed that the best smoothing of ASTER GDEM 2 is reached with such parameters of mdenoise: threshold = 0.8 iterations = 10-20 Also filtering with r.neighbors by average method and window size =5 is quite usefull to remove some noise from DEM. --- With the best regards from Russia, Alexander Muriy. ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Although the name doesn't matter. If the user wants to add extra executable directories, they can modify PATH directly. [moving this thread over to the dev list] as per earlier email in this thread, from my POV option #2 is the preferred solution. Definitely change the name away from PATH for usage which isn't $PATH anymore. if it doesn't harm to automatically prepend the $PATH, then why not make that easy for those who want to use it? Because it's one more unnecessary environment variable. Some systems have a limit (4k is common) on the combined memory used by the environment and the command line, so enlarging the environment reduces the maximum length of a command. A single environment variable is sufficient to find all components of an add-on. The original idea seems to have been based upon the assumption that an add-on would consist of a single script, with no additional files. That assumption should be false for anything from the add-ons repository (there should at least be a manual page). -- Glynn Clements gl...@gclements.plus.com ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Re: [GRASS-user] lion osx
Not anything specific. The Snow Leopard package should work fine, mostly. The main difference and problem is Python and the wxPython GUI. The Snow package uses Python 2.6 and a Carbon-based wxPython. While it seems to work on Lion, it's possible there are hidden problems due to Carbon supposedly being stripped out of Lion (I could be wrong on that). Lion needs a Cocoa-based wxPython, but the GUI doesn't run at all yet. So it's a work in progress.
