BYO map display

[mhillman]

Does anybody know if there is a TomTom application that allows you to load your own .jpg map file, and provide a moving map display (a la OziExplorer) for off road use ?

You can try using off-raod but the map files need to be .bmp - http://www.webazar.org/tomtom/offroad.php?lang=uk

Thanks for that reply, but I see no mention of support for map files in any of the documentation. Can someone advise how to get started writing an app for TomTom? I've seen mention of an SDK, but that seems to be only for Win CE versions. How do you do it for a ONE XL ?

Isn't this what you are looking for?

How can you add maps to Offroad ?

* The maps must be in BMP format and have a size equal to 480*272 pixels for GOx10 or 320*240 pixels for other Tomtom. If the size is not exactly one of the specified sizes, the width and height must be a multiple of 8.
* Maps are not moving maps, they are presented always with North towards the upper part of the screen.
* You may have as many maps as you want, they only need to be present in the /offroad/maps directory
* The maps may cover different areas, Offroad will adapt itself to show the current point and the next waypoint, in the right map.
* Offroad will change itself the map, when the current point goes outside of the area covered by the current map. If no map fits the new position, Offroad reverts back to the default screen and doesn't show anymore the current point and the next waypoint.
* Maps are chosen in the order of the description file. As soon as a map fits the current point, it is selected. So, if you want to have a more accurate map for a specific area, also covered by a less accurate map, you should put the more accurate map before the other one in the description file.
* Maps and their coordinates are described in the file /offroad/maps/config.map which contains as many lines as maps number.
* Its lines have the following syntax :

<upper left corner longitude> <upper left corner latitude> <lower right corner longitude> <lower right corner latitude> <file name>
* avec :

<upper left corner longitude> : longitude in decimal degrees (with a "." before decimals) of the upper left corner of the map

<upper left corner latitude> : latitude in decimal degrees (with a "." before decimals) of the upper left corner of the map

<lower right corner longitude> : longitude in decimal degrees (with a "." before decimals) of the lower right corner of the map

<lower right corner latitude> : latitude in decimal degrees (with a "." before decimals) of the lower right corner of the map

<file name > : file name of the BMP file containing the map with the complete path /mnt/sdcard/offroad/maps/
