<br><font size=2 face="sans-serif">Hi Folks,</font>
<br><font size=3>I have an fcell grid of elevations for the state of North
Carolina (51000 rows 133000 columns 6783000000 cells) . I tried to
run r.terraflow in GRASS7 ( 8/8/2011 svn snapshot) and ran into the dimension
limits. So I patched them according to Glynn's email , </font><a href="http://www.osgeo.org/pipermail/grass-user/2004-February/024722.html"><font size=3 color=blue><u>http://www.osgeo.org/pipermail/grass-user/2004-February/024722.html</u></font></a><font size=2 face="sans-serif">
and tried again ( Would it be better to change the dimension
variable to int instead of short int?) .</font>
<br>
<br><font size=2 face="sans-serif">This time my Streams file builds to
about 26 GB and then r.terraflow bombs with :</font>
<br>
<br><font size=3>MFD flow direction<br>
D8CUT=999999986991104.000000<br>
Memory size: 808.00M (847249408) bytes<br>
Memory manager registering memory in MM_IGNORE_MEMORY_EXCEEDED mode.<br>
r.terraflow: grass2str.h:145: AMI_STREAM<T>*<br>
cell2stream(char*, elevation_type, long int*) [with T =<br>
float, elevation_type = float]: Assertion `nrows * ncols ==<br>
str->stream_len()' failed.</font>
<br>
<br><font size=2 face="sans-serif">The memory size is interesting, because
I'm giving it 8GB of RAM out of 16 GB in the command. The temp directory
has about 900GB of space, so it has plenty of room .</font>

I get home tonight.</font>
