Hi Nick, I cannot reproduce a problem with those files. I've extracted your files and tried this with r4136: java -jar d:\mkgmap\dist\mkgmap.jar --dem=faroes --overview-dem-dist=88888 --dem-poly=args\areas.poly --dem-dists=3312,9942,16560 args\73902528.o5m Maybe you are not using the latest version of mkgmap? Older versions before r4089 did not know which files should exist: http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4089 Gerd ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> im Auftrag von osm@pinns <osm@pinns.co.uk> Gesendet: Sonntag, 18.

It only seems to happen with these hgt files, but they seem to have file sizes common to 3'' hgt files. Perhaps it has something to do with islands? For some reason it's looking for non existent hgt.zip files ... Have uploaded hgt files etc at http://files.mkgmap.org.uk/download/424/Faroe.zip Nick On 17/03/2018 10:45, Gerd Petermann wrote: Hi Nick, yes, but with a comma as separator: --dem=path[,path...] The option expects a comma separated list of paths to directories or zip files containing *.hgt files. Directories are searched for *.hgt files and also for *.hgt.zip and *.zip files. The list is searched in the given order, so if you want to use 1'' files make sure that they are found first. There are different sources for *.hgt files, some have so called voids which are areas without data. Those should be avoided.

I think the problem might be my end as I can't located the zip file on my drive. Will make some further enquiries.

Please post a link for further analyses.
