[mkgmap-dev] FW: Lines distorted

Sun Feb 1 06:04:45 GMT 2015

I'm still reading this thread but haven't tried the new mkgmap.jar yet. I
was hoping for a way to smooth polygons and Gerd's reply to Enrico
indicates that the patch and new binary only help smoothing lines, so I
stopped paying attention. But I'm interested in learning more about mkgmap
and the map making process in general.

I saw another post a while back where Gerd says something along the lines
of "people still don't know how to use a patch".

The documentation for mkgmap itself is pretty thin. There's the style
manual, and the little blurb about TYP files but nothing to tie it all
together. And I've not found anything about how to use mkgmap other then
the options text file. The explanatory statements in there are helpful but
leave a lot unsaid. A careful reading of the "Optimization Options", for
example, left me with more questions than answers.

You are the developers of the program, so many of these things must seem
glaringly obvious. But they are not. How is one supposed to know how to
utilize a patch? Is there a users manual somewhere?

Thanks,

Dave
