[OSM-talk] Graphical generation of Garmin maps from OSM data

[Nick Whitelegg]

Been thinking about building further on the osmgarminmap XSLT 
transformations and using them to develop some sort of GUI tool for 
generating .img files from OSM data. Such a GUI tool would aim to have a 
WYSIWYG interface where you can preview what the map would look like on 
the GPS before actually uploading it.

I can see two ways of doing this:

1. A standalone tool which downloads data from OSM, allows the user to 
configure the look and feel of the map, then upload the map to the GPS.
Advantages: could all be done in one step; Windows users would not even 
need cgpsmapper and sendmap as these are available as a DLL which could 
just be linked in.

Disadvantages: there is the need to download a standalone tool.


2. A web based approach; user views an area on OSM then selects "prepare 
Garmin map". Some sort of AJAX interface could then be used to configure 
the map visually before uploading to the Garmin.

Pros: mostly done through the web. My Freemap server already has the 
cgpsmapper binary installed allowing generation of .img files (I asked the 
cgpsmapper guy about whether that was ok and he said it was fine for non 
commercial use); Freemap could act as a proxy, grabbing OSM data under my 
login name.

Cons: user would still need to download sendmap to actually send the .img 
to the device.

Any thoughts on these options?

Thanks,
Nick
