[GRASS-user] Remote Sessions with NX (NoMachine)???

GRASS Users: While running Sessions Remotely using NX (www.NoMachine.com) I can have problems using GRASS's XDRIVER: With NX 2.1 the XDRIVER successfully displays Raster Images, although with NX 3.X the XDRIVER Window remains "Blank" without the Raster Image being "Visible"!!! Would prefer to

[GRASS-user] Re: How To use a raster MASK correctly?

Figured it out. Used the following r.mapcalc expression: r.mapcalc "new_hillshade=if(europe_dem < 100, 180, europe_hillshade)" I think I might be in love! -- On Sat, Oct 17, 2009 at 10:27 AM, Roger André wrote: > Hi All, > > I would like to use an elevation mask to reclass certain areas in a >

[GRASS-user] How To use a raster MASK correctly?

Hi All, I would like to use an elevation mask to reclass certain areas in a raster, while leaving the values outside the mask alone. Below are my attempts so far. Unfortunately, when I export output raster, the reclass appears to have been applied to entire raster. Is there a way to do this usi

lol Awesome! Can you imagine ESRI creating a utility this way? Thanks for doing this. Roger -- On Fri, Oct 16, 2009 at 8:36 PM, Hamish wrote: > Andrew wrote: >> > I would like to export raster files to a Google Earth >> > image (kmz or kml). >> >  Does anyone know how this is done?  I found a

Re: [GRASS-user] HowTo fix country border topology problem?

Hi Martin, Thanks, that is a exactly the problem. Your page is perfect for showing the cause and solution. One question though, since the solution relies on removing polygons whose areas are less than a minimum threshold, how can we do this accurately with a global data set? I suppose I could e

Re: [GRASS-user] can't ingest an E00 file using r.in.gdal, or anything else?

Hey Jeff, This is a valid file, though not well supported by software other than ESRI. E00 files most commonly hold vector formats, but can be used to contain raster data also. AFAIK, there is no way to import these directly into GRASS, it only supports the vector version with v.in.e00 For this

[GRASS-user] can't ingest an E00 file using r.in.gdal, or anything else?

I'm not sure why this is not working, and I'm having a little trouble getting a satisfactory answer on the web. I'm trying to import an e00 file (arc/info grid) using r.in.gdal. For example, GRASS 6.4.0svn (himom):~/Documents/rufus/incoming/wadnr > r.in.gdal input=lewis_dem30.e00 output=l

Re: [GRASS-user] v.to.rast with empty vector-file

Thanks for response, Markus! I just did that a minute ago. But I found out that I don't have to handle that exception in my case: I do a r.patch further on, which works even if one raster-file is missing. So there is no need of an null-map anymore. Thanks again, Achim Markus Metz schrieb: > >
