D3 POI

[jellied]

Getting to grips with the new favourites importer.

Just discovered the file format requires the FULL address - street, postcode etc - long/latitude are OPTIONAL, and in fact not even used according to the manual.

So all the TomTom daa is next to useless given how few contain anything but co-ordinates.

Fortunately that is not true. Contrary to what the manual says you only need four fields

- Name
- Comment
- Latitude
- Longitude

You can use commas for the rest, for example

"IAH Airport","Terminal A",-95.35058,29.98686,,,,

or you can simply omit the commas

"IAH Airport","Terminal A",-95.35058,29.98686

The only real difference to the OV2 format is the order of the columns.

I have also decoded the structure of the DAT files, so we can now craft our own converter directly into DAT (without the need for the Favourites converter)

brilliant - i tried crafting some dummy .csv files, but all reported "no data", or "corrupt record" till I added extra info.

I must admit I was very suspect that long/lat was not used as postcodes are not that precise for such items as speed cameras and items on motorways.

The decoder to .csv will be handy to edit a copy on a desktop and to keep a master copy.

ok, for the record here is the format (All values except where explicitly stated are Zero terminated Unicode strings)

- Originator (For example "Destinator 3 Favorites Importer" or "Dynamic POI" - when entered manually in the Pocket PC) - this field is not used
- Name
- Comment
- House Number
- Street
- City
- State
- Country
- 8 bytes of gibberish, starting with 01h - the rest can be filled with 00h
- Latitude (64 bit float)
- Longitude (64 bit float)
- Latitude (64 bit float)
- Longitude (64 bit float) -no idea why this is repeated)
- 16 bytes of gibberish, can be filled with 00h, except for byte 5 (02h) and 9 (32h)

and then starting over for the next POI. Looks like the file name defines the POI category. What we want to target is "Auto Alert 1.dat" and "Auto Alert 2.dat" - those are the only ones triggering the proximity alert.

Thanks for that - no idea how you managed to decode them - there again my back ground is Unix not Windows.

You are quite correct about the file format - no idea what I was doing wrong. Managed to download and convert a couple of useful ones last night and they all worked fine, though some what limited given you can't say "Show me the nearest Tesco" or sort/search the list either.

Also the icon displayed on the map are not shown once you zoom out to far, so it's quite hard to find them manually.
