Thank you Dan for the quick response. Do you know if I can use that same command but instead of creating a shapefile as the result, create a polished format file? If not, it will just be an extra step in the process but that's fine too. Thanks again.

Hi All,

Thanks a lot for putting this site together!

I am attempting to build the topo map for Minnesota. I am having some trouble after downloading the DEMs with processing using dem2topo. Most of the segments are processing just fine but a few of them are too big I believe. I get an error message that says there is not enough memory while dem2topo is building the contours. I know that there is a maximum memory for dem2topo with Windows and I know I have more than enough memory to process these files. I was wondering if there is either a way to split up the TIFF files into smaller segments for processing with dem2topo or if there is another free program out there that can build contours from DEMs without a memory restriction.

Any help is greatly appreciated. Thanks.
