Re: [mkgmap-dev] Address index for multi-country map

2013-11-11 Thread Bernhard Hiller
Thanks for your hints. With the precompiled boundaries, the map of the 
European countries receives a functional address index. When creating a 
map of South-East Asia (Thailand, Malysia, Singapore, Cambodia, Vietnam, 
Indonesia, Laos), the address index does not work: no roads are found in 
Bangkok or Kuala Lumpur!


Beyond the fact of the defectiveness with South East Asia, that 
procedure does not feel correct at all: it means that I have to get the 
same (?) data from two different locations in two different formats. Or 
even three, when using the --precompiled-sea option (which I never got 
working with South East Asia).
All those files have different update schedules which means 
inconsistencies. With central Europe, those inconsistencies are not very 
likely, since borders and coast lines are available with high quality. 
That does not apply to South East Asia. Last week I updated some 
sections of the Thai-Malaysian border, and today of the South-Thai coast.


I know that sometimes a correct solution may be very difficult, and wtf, 
let's take a shortcut with a pragmatic solution. How complicated is a 
correct solution here?

you can search the archives to find out why these solutions are preferred.
The main reason besides performance is that a part of the world doesn't
contain complete sea and probably also not complete boundaries.

If you like, you can compile your own boundaries data:
