[mkgmap-dev] Error when not using dem-poly

Mon Jan 8 10:01:46 GMT 2018

Hi Gerd

I'm using latest r4036

I'm applying what you suggested to Minko to avoid contours been given a dem.

In my dem.args I have

dem=e:\dem\europe\
overview-dem-dist=888888 
dem-dists=3312,13248,26512,53024

and get the following error:

1) When I add dem-poly=areas.poly the error disappears.

2) I also don't get the error if I replace -c dem-args with
--dem=e:\dem\europe\ --overview-dem-dist=888888 
--dem-dists=3312,13248,26512,53024

3) This only seems to affect certain pbfs.
