The raster map directory holds 2.4G of data. Trying to run nviz causes a<br>
seg fault after processing ~3%:<br>
<br>
GRASS 6.5.svn (Washington):~/grassdata > nviz elev=dem_basin<br>

Segmentation fault<br>

Anything I can do to prevent this?<br>

The nviz syntax allows us to specify multiple line/area and point maps to<br>
overlay the base elevation map. What I do not see on the manual page or in<br>
the GUI dialog box is how to specify colors, line widths, symbols, and sizes<br>
for these maps. Can this be done somehow?<br>

Hi all,<br>
<br>
Just updated to the latest svn version of grass 7. Configure went OK<br>
but I got a bunch off errors on make, the first one being in<br>
display/d.path. So I went into that directory and issued make. The<br>
output is the following:<br>

Hello Rich,<br>
with Your provided data it's not possible to tell if You can do something.<br>
Things to check:<br>
1) the size of Your computational region. On 32bit system You might<br>
hit a memory limits.<br>
2) check Your OpenGL system. Does glxinfo and glxgears work fine?<br>
3) run nviz under gdb and generate backtrace. Still You might need to<br>
recompile GRASS with --enable-debug to get also debug symbols for all<br>
GRASS parts. --enable-debug is harmless and wouldn't interfere with<br>
normal working with GRASS, it will only help to track down bugs.<br>
<br>
Here are some notes I have made for myself on running nviz under gdb<br>
and valgrind:<br>
gdb $GISBASE/etc/nviz2.2/nviz<br>
run -f "$GISBASE/etc/nviz2.2/scripts/nviz2.2_script"<br>
elevation=elevation.dem@PERMANENT<br>
<br>
valgrind $GISBASE/etc/nviz2.2/nviz -f<br>
"$GISBASE/etc/nviz2.2/scripts/nviz2.2_script"<br>
elevation=elevation.dem@PERMANENT<br>

Dear All,<br>
<br>
Doing a bit of work with tram in Vietnam using HEC-RAS and<br>
HEC-GeoRAS. It would be nice to have a GRASS interface to<br>
HEC-RAS. HEC-GeoRAS below is an interface for ArcGIS.<br>
Perhaps a project for some student or Google Summer of Code?<br>
<br>

<br>
I have also included some other modelling tools related to<br>
flood/hydrology, erosion etc. Perhaps you know most of it already.<br>
In future, it may be world considering<br>
how some of these models can be put to work together to<br>
bring out more comprehensive output of physical processes.<br>
For example there is already some work on integrating HEC-RAS with<br>
MODFLOW.<br>
