dem2tin failure w/o actionable error msg about tin-terrain HOT 4 CLOSED

@adrpar Thanks for the additional information -- I've increased Docker memory to 27GB and it still fails, but it is getting much further than previously. I will continue to play with Docker settings to see if I can get it to complete. (Also, I need new glasses because I thought the dataset was 5000x4000 when it is actually 100X larger than that. Now I understand why you immediately suspected memory was the problem.)

Hi @moosehill,

thank you for reaching out and trying tin-terrain. I would like to understand more about the reason for tin-terrain to be killed by the OS.

The dataset you are using, is it this one I found on this Icelandic page? https://vefthjonustur.wordpress.com/thrividd/ ?

Second, how much memory does your machine have?

I suspect that tin-terrain runs out of memory, but I want to test this first and eventually rule that possibility out, before we start digging deeper.

Thanks for providing this information.

Hi @adrpar,

Yes, that's the dataset, but I also used gdalwarp per the instructions in the README to convert to Mercator.

My system has 32GB. I watched the Activity Monitor while running tin-terrain and "memory used" never exceeded 24GB with memory pressure shown as about 30%.

Thanks for looking at this.

I was able to reproduce the issue and it is lies in how Docker runs on Mac. The VM that contains Docker (docker-machine) only has 2GB memory in its default mode. Therefore tin-terrain runs out of memory quite fast.

You can increase the memory by following these instructions here: https://docs.docker.com/docker-for-mac/#advanced

Or you try compiling tin-terrain natively on the Mac without Docker. If you need help with that, let me know.
