[mkgmap-dev] DEM Noddy Guide

Tue Jan 9 10:11:23 GMT 2018

Hi Nick,

no, but it logs it with a warning level.
It sometimes tries to read a hgt file that doesn't exist because it would be in the ocean, so for some maps you will find many of those messages, not meaning any error.
I am not 100% happy with this, maybe I should code a list of files which should not be searched and produce an error message for the rest?

Gerd

Hi Gerd

Oops !

sorry my mistake ; you are absolutely right.

Does the dem option provide an error msg when it can't find a hgt file?
