Just saw today that one can now buy the garmin 24K maps on a DVD and the DVD contains more states than the SD card that they were selling. He he, seems like the work on this website has got Garmin running around...

I started thinking that since cGPSMapper charges your first born child for the routing version, could we not write a MP to img converter ourselves. I started looking here and there and found a few resources. This page http://wiki.openstreetmap.org/index.php/OSM_Map_On_Garmin/Format lists them all.

I looked yesterday at the MP file format. It is basically a text file with pretty simple format. Sitting for a few hours, I was able to code up something that could load up the MP format files in memory. Now comes the difficult part. The Garmin IMG format is somewhat a mystery and in spite of some people having dug through it, the autorouting/searching part of it seems like a mystery still. Anyone else have any experience in this?

The tutorial explains how to work with the GNIS data using the GPSFileDepot program. However, after I processed it using that tool, I ended up with very few points. Today I manually downloaded the GNIS data for the state of Washington and holy macaroli, it shows a whole lotta more points in GM. So, I take it that the processing cut out some points. I was wondering what is the manual process of conversion for the GNIS points, so I can recreate the WA map with the proper GNIS points?

Hello, I am a newbie. I downloaded the DEM data for the entire state of washington and have finally after a lot of work generated 40ft contours of the whole state in the Global Mapper gmp format. Since GlobalMapper would cop out when I would give it the whole state at once, I did it chunk by chunk. Today I selected all Washington state subbasins and provided the email address to download the files in the morning but have not received anything so far. Any ideas how long it usually takes?

Thanks
