[mkgmap-dev] gmapsupp + index and Berlin/Friedrichstr.

From Martin mkgmap at snailrun.de on Mon Jan 9 11:19:41 GMT 2012


I done some tests. You can find the results here:

First I downloaded a tile which contain only the Friedrichstraße in Berlin:
Then I build mkgmap from trunk and build a map using the 
--gmapsupp-option (only_fs.zip). When I search for the Friedrichstraße, 
I didn't fine any Friedrichstraße.
So I added a further street (Rheinhardtstraße) to the osm-file. And now 
I can find every Friedrichstraße on the tile (with_other_only_fs.zip).
So I downloaded a further tile:
When I now build the map with the first tile (w/o Reinhardtstraße) I 
also couldn't find the Friedrichstraße, but the other Friedrichstraße in 
the other cities. (two_only_fs.zip)
If I use the tile with Rheinhardtstraße I can find the Friedrichstraße 
also in Berlin. (with_other_with_other.zip)

For all tests I used my Oregon, I don't have Mapsource or Basecamp here 
(I'm using Ubuntu).
For the streetsearch I entered the City. If I leave it out, I can find 
the Friedrichstraße every time in Berlin.
Also if I find the Friedrichstraße now, if I build more tiles it's not 
possible to find the Friedrichstraße (I forgot to mention that the 
Friedrichstraße is just an example, there are more streets, which 
couldn't be found).
