Hi,
I tried to build DEM file using GlobalMapper with SRTM layers available in the net.
LK8000 always crashes once I set new DEM file. (Memory could not be "Read")
At the same time DEM files from LK8000 download page could not be opened by GlobalMapper. |

No, my DEM files are less than 5mb.
I can see one big difference. LK DEM files are binary files.
But files from GlobalMapper are text files.

That could make sence why both programs don't understand each other files. |

| I have been trying to create my own DEM file as well but without success. Information on the file format seems to be non-existent and there appears to be some reluctance to share it - not sure why that would be. |

Good reason!
For my part, I am not looking for detailed step-by-step instructions. Just point me in the right direction, although I realize this may not be possible if, for instance, the file is compressed using a customized algorithm or something similar.
At any rate, if I was to be successful I would be happy to take the time to write up instructions if that was something that would be desirable.

I cannot dedicate time to support map creation right now, but I can provide you with the SRTM tools I have been using.
They are in perl and C language, so you need the C compiler at least.
I spent a lot of time in 2009-2010 , and I am sorry my memory is like a swiss cheese since some time.
Please contact me via email and we can arrange a skype voice meeting, so I try my best to let you understand (AND WRITE DOWN DOCS!).
