Tomtom Western Europe Navteq+Teleatlas POIs Merged
Requirements: Windows Mobile PocketPc with Tomtom Navigator 5 or 6 installed.
Overview: POIs file combined from both map sources (Navteq & Teleatlas).

This merged POI.DAT file contains the superset of the two map sources, with duplicates removed, to create a file which should have the data of both TeleAtlas and NavTeq. Note 1223 and 1219 POI.dat are the same (Teleatlas)

Items have been considered duplicates within a given category if they fall within 150 feet of another item. For categories where you would expect 'close proximity' - e.g. shops, restaurants, the distance is 50 feet.

Note that there will be the odd duplicate when NavTeq and TeleAtlas wildly disagree on the location of a POI.... I haven't manually checked all 1.7 million POIs

Download Instructions: HERE_(Rapidshare) or HERE_(Sharebigfile)

To Install: Un-rar and copy over existing POI.DAT file in the map directory (take a backup first)

How to merge the POIs:

For the folks wanting to know how to merge, my post on PPC Warez (great forum) explains:

(You don't need this bit if you just want to get the POI.DAT from above.

Extracted/re-compiled using script (see http://www.licour.com/), merged using GPSBabel (http://www.gpsbabel.org). Also need to install ActivePerl to run extraction scripts.
- make navteq, teleatlas and merged directories
- copy both poi.dat files to poi_from_navteq.dat and poi_from_teleatlas.dat
- extract as two sets of .asc files:
perl extract_ttpoi.pl -f poi_from_navteq.dat -w navteq -a
perl extract_ttpoi.pl -f poi_from_teleatlas.dat -w teleatlas -a
- merge using gpsbabel. An example batch file that assumes the separate asc files are under navteq and teleatlas directories to combine into merged directory.

- Recreate poi.dat in 'merged' directory. Place poi.lst in merged directory

http://rapidshare.com/files/8918831/poi.lst.html

..and then:

perl create_ttpoi.pl -i poi.lst -o poi.dat -v


C'est tout

/s


(The GPSBabel bit takes many hours)

REPOST after PPCWAREZ DB crash

Merci car cela évite de refaire à chaque fois de fastidieuses manipulations
Par contre j'ai essayé de traduire en français tes explications avec Babel Fish, mais c'est incompréhensible.
Bienheureux anglais !!

Thanks

Thank you because that avoids remaking each time of tiresome handling

On the other hand I tried to translate into French your explanations with Babel Fish, but it is incomprehensible.
Happy English!!

Nice release, and thank you a lot for tihs "repost". 15 WRZ$ reward for this useful post (even if this is not an official release).

This topic will be cetegorized in GPS subforum.

Thanks for your work and for the How2, mainly.

I have a question, as I found many POIs in my town like 2 (or 3 !!!) copies of the same object
(I guess farer than 150/50 ft, though):

TeleAtlas 1223 and 1219 versions have the same POI.DAT:
37.182.659 bytes / 07ba07d5b05602688376a13e7267e56a MD5 hash

Navteq 1256 have this POI.DAT:
19.068.565 bytes / 501a20d348d01eaa7c5bf285e4515761 MD5 hash

How the merged file could be
68.723.651 bytes / 829e7670d8aed1ccceec96d2fd4c2b0e MD5 hash

(greater than the sum, with many - I guess - dupes removed) ???


Thank you for any further info about the process

I think the repacking process is less efficient than the tomtom's own.

Number of POIs (merged)= 1739758
Number of POIs (Teleatlas)= 1273684
Number of POIs (navteq)= 668232

Teleatlas+Navteq= 1941916

Number of duplicates removed= 202158

I think it is a fair bet Navteq and Teleatlas disagree on where things are!

Anyway, I erred on the side of caution rather than removing adjacent different POIs.

Many thanks for these details. I'm trying to go deeper this matther, and would solve this stupid arithmetic problem, first.



Thnx

Nice release

it seems to me though that all "special" characters (eg. french accents) are replaced by dollar sign. How come

/fxpal

[Seraph]

Looks like a babel problem - I'll investigate

/s

Is correct poi.dat at the moment? tnx.

[Seraph]

With the exception of some of the names being a bit messed up (accented characters replaced with '$' sign), this is the most 'complete' poi database.

/s

ok can someone make a final merged copy and upload it ?

can somebody upload teledat und navteq poi.dat separately.because of the mess with $ ?

[timothy]

Great release. Very nice for the maps.

can somebody upload teledat und navteq poi.dat separately.because of the mess with $ ?
mfg

But those come with the Western_Europe_660.1256 and Western_Europe_660.1219 maps. Do you not have the original poi.dats?

[Seraph]

When I have finished painting the spare room, I hope to fix this!
