[mkgmap-dev] sea hgt files

Thu Jan 4 14:31:59 GMT 2018

Hi Gerd

I think there is still an issue when --x-dem searches for sea hgt files
which by design don't exist . After splitting the UK with maxnodes at 160000
and selecting the far south west (Cornwall) tile I get an error - see below.

Its looking for  N49W008.hgt which is just sea.
Would it be possible to ignore a .hgt if it doesn't exist or use Frank's
dummyvalues idea?
