Why this document
Since years, a lot of people wanted to add their own POI to those already included in the navigation CD for RT3. Most of people wanted to add radar or velocity camera, but some others wanted also to add various customized POI (friends, …) Starting with version 5.5/6.6, the RT3 software lets the user select radar as a kind of POI. But it is a useless option because there is no radar in the cartography itself. The main goal of this document is to describe the data structure of the cartography to be able to write a software which can customize POI known by they latitude/longitude and generate a new version of the cartography Another goal (perhaps more complex) would be to merge two (or more) CD for people (like me) living near a border. In a day to day usage, it’s a pity the Major Road of Europe cartography is totally blank after I cross the German border using a brand new bridge followed by a small road. And a lot of other usage may be found in the future…
1.3.
CD version(s) described
This document is based on a CD Navteq for RT3 France 2005/2006 2nde edition (TR3002900). These information don’t apply to “old” CD structure (2004 and before, 2005 for certain countries) without compressed files (if there is a LABEL.TXT file in the root or directories with name containing letters like C_00 or L_00, this is an “old” one).
Filenames used in CD for other countries may change (see 4.1 Files naming rules). Structures should be the same for newer versions as well as for other countries version. File size, number of record, exact content (see 4.4.1 File size (TD3002900)) depends of course of the cartography version and country.
2. Main contributors Phil95 : Many thanks to phil95 for all his work. complete description of localization by zones, the way to deflate compressed files, graphical representation of POI and maps… I’ve just renamed GC, MC, PC into LS, MS et SS to ease the english translation of this document. dkomputer : Thanks. Without you, I still find a regular pattern into FRANCXXX.DSC instead dividing it by 17. Janfi67 : I’m trying to collect all the available information and to summarize it in this document. Sorry for my poor English.
3. General information 3.1.
Localization by zones
Places, POIs, cartography elements are often localized in this way The European map is divided in a first level of 12 (horizontally) by 18 (vertically) large squares of 256Km by 256 Km called LS. Then each LS is divided into 256 medium squares (16 horizontally by 16 vertically) of 16Km by 16 Km called MS. Finally, each MS is divided into 256 small squares (16 horizontally by 16 vertically) of 1Km by 1Km called SS. Zones are numbered from 0x00 to 0xFF from West to East, then from South to North.

South Inside a Small Square, a POI is fully localized by two coordinates, X and Y between 0 and 999. POI coordinates are LS, MS, SS, X and Y. Another way to express them using a common geodesic language is : Formulas to translate LS, MS, SS, X, Y into E, N: E = 256000 * LS mod 12 + 16000 * MS mod 16 + 1000 * SS mod 16 + X N = 256000 * LS div 12 + 16000 * MS div 16 + 1000 * SS div 16 + Y
Formulas to translate E, N into LS, MS, SS, X, Y: LS MS SS X Y
= = = = =
(E div 256000) mod 12 + 12 * (N div 256000) (E mod 256000) div 16000 + 16 * ((N mod 256000) div 16000) (E mod 16000) div 1000 + 16 * ((N mod 16000) div 1000) N mod 1000 E mod 1000
Formulas to translate LS, MS, into column and line: column = 16 * (LS mod 16) + MS mod 16 line = 16 * (LS div 16) + MS div 16
Where mod is modulo, div is the integer division. Due to the projection used for creating the planed map MS are not north – south oriented Column 0-120 Column 121 (10°2’) Column 122 – 191
: decreasing positive rotation : minimum rotation (origin in this column) : increasing negative rotation
This seems to indicate a kind of cylindrical projection with a center longitude of 10°2’ E (false East) and N (false North) should be in meters with the given definition. Sometimes coordinates are LS, MS, X, Y with X and Y from 0 to 15999
Metropolitan France plus Corse is divided in 18 zones from west to east then south to north: 0x2b : Corse sud 0x33 : Hendaye – Cambo les bains 0x34 : BAGNÈRES-DE-LUCHON – LAVAUR
0x35 : Cerberes – L’isle sur la sorgues 0x36 : SIX FOURS LES PLAGES - CASTELLANE 0x37 : Corse nord 0x3f : Bidard – MESSANGES 0x40 : AUCH - BEAUNE-LES-MINES 0x41 : GRAULHET – CHÉNAS 0x42 : PERNES-LES-FONTAINES - VILLE LA GRAND 0x4b 0x4c 0x4e 0x57 0x58 0x59 0x5a 0x65 : ÉQUIHEN-PLAGE – LEFFRINCKOUCKE
3.2.
POI localization by country, region, department city and district.
This is another way to localize POI and places : It is used on some of the files and directories of the navigation.
\P_RR\CAT\ P : country 1 : Italie 2 : France 3 : Allemagne 4 : Belgique … RR : Région (area? Something else?) in the country … 10 : Alsace … DEP : Départment in the area 001 : Bas-Rhin 002 : Haut-Rhin For example, the \P_RR\CAT\DEPDCP.CAT file describes cities of the department, identifying them by a number (after the name) and sometimes with one or more district number (after the city number, 0xFFFF if there is no district)
4. File structure The structure should be relevant for all versions with compression (to be verified)
4.1.
Files naming rules
The tree structure and the file names under the root don’t depend on the country. Of course, directory names depend on the country (see 3.2 POI localization by country, region, department city and district.) but because of the presence of Major Roads of Europe on all CD, the structure is still present on all CD. The only difference between CD is the content of the files (more details for the CD country) Some file names at the root level are always the same (they don’t depend on country): • • • • • • • •
CONFIG.LOG DB_DWNL.OUT DCN.DAT GRUPPO2.DAT GUIDA_CHAMPERARD.POI (not present on all CD) SCITTANAME.DAT SIF.VER SW_VER.DAT
Of course, the content is not the same. All the other file names start by the country name encoded in 5 characters: • • • • • • • •
BENEL for Benelux (to be confirmed) CEUR1 for MittelEuropa Süd (Switzerland, north of Italy) CEUR2 for MittelEuropa nord (Austria, south Germany EST_E for East Europe FRANC for France GERM for Germany ITALY for Italy SPAGN for Spain/Portugal
In the document, all file names are related to France but you can easily translate them for your own CD.
4.2.
Files in the tree structure under the root 4.2.1. P_RR\CAT\ZZZDCP.CAT
List of cities ands districts of the department. As many files as departments in the Area (RR) of country P

Position 0 – 45 46-47 48-49
Content City name City number District number in the city (0xFFFF if not significant)
4.2.2. P_RR\IND\ZZZCOM.IND Points to the first POI (by category in the FRANCXXX.DSC files) related to city/district 52 bytes records (as many as entries in ZZDCP.CAT file, then 1 record per city or district)
Position 0-1 2-3 4-7 8 - 11 12 - 15 16 - 19 20 - 23 24 - 27 28 - 31 32 - 35 36 - 39 40 - 43 44 - 47 48 - 51

(0xFFFFFFFF if not significant) Index (from 1) of the first record in ZZZTOP.LET related to the city/district. (0xFFFFFFFF if not significant) Index (from 1) of the first record in FRANCSEM.DSC related to the city/district. 0xFFFF if there is no POI of the type in the city/district. Index (from 1) of the first record in FRANCSAF.DSC related to the city/district. 0xFFFF if there is no POI of the type in the city/district. Index (from 1) of the first record in FRANCSHR.DSC related to the city/district. 0xFFFF if there is no POI of the type in the city/district. Index (from 1) of the first record in FRANCSTU.DSC related to the city/district. 0xFFFF if there is no POI of the type in the city/district. Index (from 1) of the first record in FRANCSSH.DSC related to the city/district. 0xFFFF if there is no POI of the type in the city/district. Index (from 1) of the first record in FRANCSSP.DSC related to the city/district. 0xFFFF if there is no POI of the type in the city/district. Index (from 1) of the first record in FRANCSTR.DSC related to the city/district. 0xFFFF if there is no POI of the type in the city/district. Index (from 1) of the first record in FRANCSAU.DSC related to the city/district. 0xFFFF if there is no POI of the type in the city/district. Index (from 1) of the first record in FRANCSCC.DSC related to the city/district. 0xFFFF if there is no POI of the type in the city/district. Index (from 1) of the first record in FRANCMIC.DSC related to the city/district. 0xFFFF if there is no POI of the type in the city/district. (to be verified)
Open Point : Ceci est valide en France; il semble que pour certaines catégories (SEM par exemple), il y ait des POIs en Italie (Pays 1) et que la numérotation recommence a 0 pou la France (point a vérifier). Pour d'autres catégories (SHR) la numérotation ne recommence pas a 0 pour la France. Ceci a pour conséquence que deux fichiers IND peuvent pointer a tort sur les mêmes POIs (a vérifier)

For each POI contains information used by the display process (coordinates in a MS, pointer in FRANCPOI.DAT, scale…) 12 bytes records sorted by increasing LS, MS ands SS. FRANCDSP.POI contains: All records of FRANCPOI.DAT Records with type 0x115C (NAMED PLACE / CENTRE VILLE) contrary to FRANCPOI.DAT which doesn’t contain such record. Records of this type point to random records of FRANCPOI.DAT
Remark : This file is used for display but doesn’t contain full coordinates of POI. Pointers to this file exist in FRANCDPA.LZW (thanks again phil95). Data pointed in FRANCPOI.DAT are not all used during display. For example, the city name is not used even if you are looking for information for this place.
Position 0–1
Content 12 LSB bits : POI type (ex 0x11E4 for public sport airport, 23A1 pour city hall, 0x16A8 for a restaurant) 4 MSB bits : 0x04 if this POI has an entry in the « guide Champérard » (a restaurant in the guide has 0x56A8 for value) 0x08 if ??? (seems to be used with 0x1F04 sports complex, 0x1F3C amusement park) POI X-coordinate in its MS (0 to 15999) POI Y-coordinate in its MS (0 to 15999) Pointer (to obtain the real address in the file, decrease the value by 1) to the POI record in FRANCPOI.DAT. not significant for type = 0x115C Display flags? Max scale to display the POI?

4.3.21.
FRANCPOI.DAT
Contains address, type phone number and localization of all POI. 293780 variable length records: a variable length string (at least 0x00) followed by 27 bytes. No obvious sort. Records seem to be grouped by set of SS, MS et LS, but some are at other place in the file and the same LS, MS et SS can be found elsewhere in the file.
Position 0–n n+1 n+2 n+3 n+4 – n+5

FRANCXXX.DSC
8 files, XXX = SAF, SAU, SEM, SHR, SSH, SSP, STR, STU There is one file per category, except for MIC « restaurant: Michelin » (POI number = 0) and SCC (NAMED PLACE/centre ville).

Pointer (to obtain the real address in the file, decrease the value by 1) to the
POI record in FRANCPOI.DAT. If the same pointer appears several times (synonyms), all the other values in the records are the same except of course for the next field Index (starting from 1) of the POI name in FRANC_NOMSERV.DAT. There is one record for each name, not only for the canonical name. For each synonym, the other fields of the record are the same. Sometimes, 2 canonical names have identical records (except this field). It can be : The same POI with 2 canonical names (ex : complexe sportif de l’ill, centre sportif d’ill) Different POI with the same “generic”name (ex 13846 CLUB MUNICIPAL DE TENNIS). There are some exceptions : In FRANCSSP.DSC, there is one record with this field set to 0 (index start at 1). Does it mean no name? 10B in FRANCSSP.DSC (which doesn’t seem to be a canonical name)

5. Comment ajouter un POI Si vous avez bien tout lu et tout compris, ce paragraphe est inutile… Mais ça fait toujours du bien de récapituler. 1. Calculate POI coordinates: LS, SS, MS, X et Y (both versions, with short and long X, ). How to do that? I don’t know… yet 2. I suppose the POI is already in a SS which has an entry in FRANCDPA.LZW. Otherwise it’s more complex. 3. Create a new entry in FRANCDSP.POI with the type, long X and Y, a pointer (already existing if you don’t need to shearch for this POI) to FRANCPOI.DAT, a scale and associated flags. Where to create this entry? I don’t know 4. in FRANCDPA.LZW a. increase by 1 the POI number located in LS, MS, SS. b. increase by 1 all the index to FRANCDSP.POI following the modified entry.
5. Pour permettre la recherche, il y a des étapes supplémentaires, insertion d’une entrée dans FRANCPOI.DAT, FRANCXXX.DST, FRANCXXX.DSC, FRANC_NOMSERV.DAT, SCITTANAME.DAT, ZZZCOM.IND … mais c’est une autre histoire. Et puis, si vous ajoutez les radars, je doute que vous soyez saisis du besoin irrépressible de vous diriger vers le plus proche ;-) Attention, ce document n’est qu’un draft, je ne garantis ni la méthode ni le résultat…
