[mkgmap-dev] mkgmap r4022 ready

Thu Dec 28 10:01:30 GMT 2017

Hi all,

see the log message http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4022 
for details about the changes.

I've also experimented with code to read a *.poly file and use that to define an area for which mkgmap should 
not calculate DEM data but was not happy with the results so far. Maybe I'll try again.

Henning has pointed me to an error:
It seems that mkgmap (and probably also BuildDEMFile) somtimes create invalid DEM data 
for areas where the hgt files contain large holes, esp. when resolution is low (high dem-dist value).
See e.g. http://files.mkgmap.org.uk/download/377/holes.jpg
I try to find out more now.
