[GRASS-user] Landsat SLC-Off gap filling
Hi - Is there anyone out there who has worked on an algorithm to fill gaps in Landsat ETM+ SLC-Off data? Now that the Landsat 7 archive is freely available I am looking for an open source approach to fill the gaps in the SLC-Off data and GRASS seems like a good option. I'm most interested in multi-date approaches but at this stage I'm looking at single-date approaches as well. Any ideas?

+1 I had just downloaded new Landsat 7 SLC-Off data. It still useable for land use change analysis. A grass tool would be very helpful. cheers, maning On 10/20/08, Ned Horning [EMAIL PROTECTED] wrote: Hi - Is there anyone out there who has worked on an algorithm to fill gaps in Landsat ETM+ SLC-Off data?

Re: [GRASS-user] How to install Grass into Ubuntu
Hi Matt, it depeds who are these users. If you run grass as you, you can manage mapsets in your home folders without having to run it with sudo... If you want to work on others' homes you need the sudo permissions, as any other operation. 2008/10/20 Matt B [EMAIL PROTECTED]: Hello list, I'm using Grass on ubuntu 8.04. Weird thing is that unless I run it sudo grass I get a bunch of errors (and it's unusable) related to grass not having the correct permissions to write to where I keep the data (ie the users home directory). It's not a show stoppper at the moment and only slightly annoying. I'm not sure why this is but I have some ideas to hunt down when I get time.

[GRASS-user] Correcting Junctions
Dear all: I have two vector maps, one with road segments, and one with junction points. But I know the Junctions aren't 100% correct. Sometimes there are intersecting road segments. I want to find out which nodes in the junctions map are unnecessary (if any), and which are missing. How can I accomplish that? Any help appreciated. My approaches so far were to use v.net (nodes) on the road segments to create correct segments and nodes in a new layer. My understanding is that the new layer now contains correct nodes and line segments. Then I tried to use v.overlay to find nodes in my nodes map that overlap nodes in the newly created map. But the result was empty. I also tried to use a SQL Query on the new map to select all cat that aren't in the junction map, but that didn't work either. I'm quite new to grass, and unfortunately I'm stuck now. Could you please give some advice?

Note that GRASS won't let you select a mapset as the current mapset (where new files are stored) unless you own it. Write permission isn't sufficient. If you are creating a location which is to be shared by multiple users, you either need to create a mapset directory for each user, owned by the user, or grant all such users write permission on the location directory so that they can create their own mapset directory (which they will own). -- Glynn Clements [EMAIL PROTECTED] ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

The file is opened with open() followed by fdopen(). The fdopen() has the b modifier, but I don't know if that works for fdopen() (the MSDN documentation implies that it should, but that may just be because the fopen() documentation was copied verbatim).
