I am trying to convert a small DEM (1 megabyte) into contours. When I go to - Extraction - Contour- and run it I get the following message:
"ERROR 1: CPLRealloc(): Out of memory allocating 416 bytes." It doesn't seem to matter what the contour interval is, although I will get a slightly different error message (for example 40 bytes). And, I have successfully converted a much larger DEM in the past. Now I get the same error message when I attempt to convert that one to contours as well.
Computer doesn't have the most power, but it worked in the past. Windows 7 Professional, 2 gigabytes of RAM, I have tried different contour intervals, checked the projection, made sure no other applications were running, and can't think of what else might be going wrong.
