Subject: d.rast core dumps. problems with rectified grids?
Platform: Linux/Intel
linux cpu: AMD (K6, ...)
Xwindows version: Xfree 3.3.6
Xwindows manager: KDE 2.x
TclTk version: tcl/tk 8.0
grass downloaded at: Hannover site
grass binary for platform: I compiled the sources myself
grass sources source: no, I got a source code package from the server, pre-2
c compiler name: gcc
I am working on aerial photos and want to compare photos from two different years.
I have imported the scanned images into two different XY-locations and have i.pointed
and i.rectified them to a common gauss-krueger location. A problem is that I
do not (presently) have a DTM for the area, but as my area of interest is relatively
flat, I have tried to manage without. The rectification goes OK, but one of the
images causes a core-dump when I try to display it, although it looks fine..
I have digitized covers for the interpretation of the images in the XY-locations,
all the covers have been rectified (seemingly) just fine, but some of them get
messed up and causes a core dump during d.rast. For the covers, I have tried
to "cut them" into smaller pieces, but to no help.
If somebody wants to, I can send them the offending covers (or maybe the entire
locations) |

Hi,
I had a similar problem recently when rectifying SAR data (500MB).
95% of the map were ok, then d.rast crashed.
The reason was simple: the tmp space in the LOCATION was full,
so i.rectify did not fully finish. The problem is that i.rectify
doesn't send a warning about this.
Proposed solution:
- The G_put_row() function in i.rectify will have a negative exit
status in case of file-system-full. Put this error (and all others)
into the mail which is sent to the user after finishing i.rectify.
Up to now the module silently dies.
Should not be too difficult, but I don't have time to fix, sorry.
Best regards
Markus Neteler

Thanks! I'll try rectifying again, watching the disk space.

Hi,
the problem has been fixed by Eric - it was a bug in i.rectify (writing the
wrong format header).
The latest i.rectify in CVS should be functional.
Cheers
Markus
