[mkgmap-dev] Address search on device with --x-split-name-index option

Tue Apr 11 08:06:20 BST 2017

Hi Steve,

I just noticed that the gmapsupp produced by MapSource changes a lot when I enable/disable option --x-split-name-index, so it probably calculates the gmapsupp index
based on the index calculated by mkgmap, not from scratch. If that is true it is probably not a good idea to use that as a reference.

Hi Steve,

sorry, maybe I made a mistake while testing.
The search for "Rheing" in Feuerthalen shows a list with "Rheingasse" and "Rheingutstrasse", when I select "Rheingasse" and leave the house number field empty it lists
"Rheingasse 10", "Obere Rheingasse" , "Untere Rheingasse" and "Rheingasse".

The search for "Rheing" in Switzerland (no City) also lists "Rheingasse" and "Rheingutstrasse" , when I select "Rheingasse" and leave house number empty it shows a map with Rheingasse 2 in Basel.
I expected to see a list with all roads named "Rheingasse" (or maybe all roads containing "Rheingasse") in Switzerland, but the device only shows the one in Basel. I am sitting near Bremen, distance to Basel is 598km , distance to Feuerthalen is 580km, so maybe it just selects the first match.

One point that might be interesting: I compare the listing produced by MdrDisplay for the gmapsupp produced by r3449 and the one from MapSource.
I see a much longer list in Mdr17 for r3449.

Gerd

Hi Steve,

good question.
The street search works but searching for "Rheing" in Switzerland doesn't list "Obere Rheingasse".
The city search is similar, I also don't see "Obere Rheingasse" when I search for  "Rheing" in Feuerthalen.

I do find "Rue de la Concorde" when I search for "Conc" in France and also when I search it in City Huningue in France.

Unfortunately MdrDisplay fails to print the mdr 22 index for the gmapsupp produced by MapSource. It writes a few lines and then an error:
--------- MDR 22 (streets by country) ------------------------------------------

Similar problem with the gmapsupp produed by r3449:

Hi Gerd,

> same problem with r3449 and r3472.

Oh that is a shame.  Does it work if mapsource creates the gmapsupp?

The mdr20 looks similar in either case, although the repeat flags are
incorrect in the mkgmap generated one.
