I struggled today with the DEM/hgt files in a zip. After downloading some extra and checking/rezipping finally my maps did not work anymore.

I do not have the exact error anymore but it was clear: DEM HGT files not found

Now it looks like if the ZIP does not have a folder but only the HGT files on the root of the zip then mkgmap does not recognize them

If I rezip everything again and put the files within a subfolder first, it is oke.

For me its fine, I solved ‘my’ issue, but if this is true it could better be in the manual or solved in code.

Looks like this does not work:

world-hgt.zip\N00E006.hgt

world-hgt.zip\N00E007.hgt

world-hgt.zip\N00E008.hgt

And if I do it like this its oke

world-hgt.zip\world-hgt\N00E006.hgt

world-hgt.zip\world-hgt\N00E007.hgt

world-hgt.zip\world-hgt\N00E008.hgt

Kind regards,
