Re: [GRASS-user] Building GRASS on Windows
I finally found some time to get back at this. I now have Grass 6.5.0 running in Windows using the process at: http://trac.osgeo.org/grass/wiki/CompileOnWindows Thanks to those who have been maintaining that information! v.net.iso now runs lightening fast (I can finish in 5 minutes what did not finish in several *days* in 6.4.0) so I will be continuing my work with that soon! Cheers, and thanks again!

[GRASS-user] Building GRASS on Windows
Hi all, I'm following along with the instructions here: http://trac.osgeo.org/grass/wiki/CompileOnWindows and am getting stuck at Step 5 under PDCurses. When running: make -f mingwin32.mak DLL=Y all The following error occurs: $ make -f mingwin32.mak DLL=Y all gcc -c -O2 -Wall -I.. -DPDC_DLL_BUILD ../pdcurses/addch.c In file included from ../curspriv.h:25, from ../pdcurses/addch.c:14: ../curses.h:50:57: stdio.h: No such file or directory In file included from ../curspriv.h:25, from ../pdcurses/addch.c:14: ../curses.h:928: error: syntax error before '*' token ../curses.h:1010: error: syntax error before "FILE" ../curses.h:1027: error: syntax error before "FILE" make: *** [addch.o] Error 1 Any thoughts? I'd really like to get a new version built so I can play with v.net.iso improvements, but am struggling!

Re: [GRASS-user] v.net.iso Performance
Hi all, Was unsuccessful in building Grass 6.5 on Windows (new at this!) and thus haven't been able to test v.net.iso. I will try again at some point on an Ubuntu machine, and report back. However, it may be a while! When will 6.5 or newer be available as a package in OSGeo4W?

[GRASS-user] v.net.iso Performance
Hi all, I'm using v.net.iso on a very large dataset (National Road Network for Ontario, Canada - 497879 lines) to determine drive-time 'rings.' I'm experiencing extremely long calculation times. Since it's a very large dataset, I'm not entirely surprised. However, my initial tests were done using GRASS 6.3.0 under QGIS 0.11.0 and I stopped the process after 5 full days of running. After these 5 days, it was still at the "Building Graph" stage. I did a search, and found a thread here: http://trac.osgeo.org/grass/ticket/224 which seemed like a good fit. Hoping that this was the solution, I downloaded GRASS 6.4.0RC3-2 via OSGeo4W, and ran the same command on the same dataset--this time it quickly proceeded to "Build Graphs" but got hung up on "Registering Arcs" where it sat for for 24 hours with no progress. Instead of waiting endlessly, I stopped the process, and am writing this in hopes of another solution. My question--is the fix outlined in the thread above implemented in GRASS 6.4.0RC3-2 via OSGeo4W? If so, how long should such a process expect to take? If not, what is the easiest way to get the code with this fix? I'm not very experienced with building from source, versioning, etc. but willing to learn if necessary.

[GRASS-user] v.net.iso usage - including speed as factor
Hi all, I'm trying to calculate drive time 'zones' using v.net.iso. I've worked through the examples using spearfish data, and seem to get suitable results using only the line 'distance' as the factor. However, I'd like to include the speed limit as another factor in the calculation, and can't seem to find any examples of how to do this. I've looked through the examples here: http://grass.itc.it/grass64/manuals/html64_user/v.net.iso.html and here: http://www.dinama.gub.uy/grass/grass57/tutorial/network.html (which mentions "This calculates the reachability map based on the vector length for 1km, 2.5km, 5km and 10km. Another option were to use vector line attributes from a DBMS table which may contain velocity, street types etc." - so it appears to be possible! Can anyone point out what I'm missing, and/or the appropriate command or switch?
