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

[Gerd Petermann]

Hi Steve,

r3893 creates now the same mdr17 records in gmapsupp  as MapSource when map is 
created with --x-split-name-index.
Please review my changes in the branch.

I still see one small difference in Mdr 4:
mkgmap writes this entry
0250 | 18 | 2a 00 00| Type 0x2a00.  Unknown 0x0
and MapSource doesn't.
Maybe the sub type 0 is not needed what other subtypes follow?

Gerd

That's true, it is not used and does not need to be calculated for the
desktop index.

Hi Steve,

I think that means that mdr17 should only see those mdr7 records which have 
getNameOffset()==0 ?

Oh yes you are right, from a quick look it appears that mkgmap is
ignoring the name offset when creating mdr17 so there are a lot of
extra and out of order entries.

Hi Gerd


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.


It is true that it uses the desktop index to generate the device index,
but it is still useful information because the formats are different
and so it has to calculate those, and some things have to be recalculated
anyway.

So as you noted it appears to be fixing up mdr17, and it also
fixes the repeat flags.

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.

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:

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.

Hi Steve,
same problem with r3449 and r3472.
I did a clean svn checkout for both and compiled and copied the jar into my

My options:
--max-jobs --route --bounds=bounds.zip --index --housenumbers --gmapsupp  
--x-split-name-index -c template.args
The template.args contains a few tiles in the alps. I've uploaded them to
http://files.mkgmap.org.uk/download/346/split.zip
in case you want to try on your own.

The on device version of mdr20 certainly supports this, so it should
work even if it is broken now.  We need to find out if this ever
worked properly eg in r3472 or r3449

Hi all,

not sure how this works on other devices. I have a map containing a part of the 
alps with parts of Germany, Switzerland and France.
On my Oregon 600 when I search for an address I have some dialogs
1) select a country (I select Switzerland)
2) select city or select "search all"
3) Enter Street name. I can type a few characters and press enter. The device 
presents a list of road names matching the selected characters.
4) Last is to enter the house number.  I can leave it empty to search for 
streets.

If I select a city (Feuerthalen)in step 2) everything seems to work fine. It 
lists "Obere Rheingasse" as well as "Rheingasse" when I enter "Rheinga".
If I select "search all" the results are weird. Sometimes I get "no result, 
change search parameters", sometimes results look ok.

When I change the code in mdr20 to ignore the additional entries produced with 
the "--x-split-name-index" option the problem seems to be solved,
I just don't find "Obere Rheingasse" when I search for "Rheingasse".

Does anybody see better results in this case with a map produced  with trunk?
