GPS help

Getting closer...
gpsbabel -i kml -f filename.kml -x transform,rte=trk,del -x position,distance=100m -o gpx -F filename.gpx

huh - you mkaing tracks now? You know that GPSbabel has a GUI so you don't have to use the code (unless you are doing the right click to modify and upload thing).

My experimenting shows that any one route can only have 250 points (with the Legend HCx) else it gets truncated by the GPS. These are rtept's not way points. Also any one file contain more than one route and they can all be loaded as separate routes onto a GPS.

Plan is to have 5 250 point routes in one gpx file for the DB1k and a second file that contains somewhere around 10 50 point routes with logical end points so changing from one route to another is not an issue (unless the GPS does it automatically - test this on Sat night).

rte=trk makes any trkpts into rtepts - still looks weird though - was wondering why trk=rte didn't change anything.

gpsbabel may have a gui on windows...

As long as the routes are uploaded via MapSource I can get several 256 point routes on with no waypoints generated.
If I use gpsbabel to send them I get waypoints generated for each rtept.

Right...
gpsbabel -i kml -f filename.kml -x transform,rte=trk,del -x simplify,crosstrack,error=0.02k -x simplify,count=250 -o gpx -F filename.gpx

Will change a kml track file (works with multiple tracks in file) into a selection of trimmed 250 point max routes with a crosstrack error of 20m (remove redundant points - works quite well).

Load this gpx into MapSource, rename the routes and it works well for uploading into the GPS.

Addendumdum...
Using only the crosstrack error filter at 20m reduces the 3981 point track from the French Pass (8 hour) ride down to about 250 points without specifying the count=250 option as well.
Got to be good for you.

I could do with some advice as well, I have a Garmin 276c. What should I load onto the gps as my base maps?

Not sure that I have down loaded correctly, there is no detail on the map, is it something you can talk me through on the forum or am I better to talk to you by phone?

Do you have mapsource installed on your PC? If so down load the free open source maps from this link (Nordie gave you a link to the associated forum). The map set is available from my link clicking on the "installer: 25637 kB" and saving it to your PC. Once you have save the file to your machine double click it and it will open and "installer" - click next, yes as appropriate.

Once this is complete open map source and along the top tool bar next to the print icon use the drop down menu to select "Free Open GPS NZ Autorouting". Make a route now and it will automatically autoroute along the available roads. If you want to upload the maps to your GPS use the "map tool" (icon that is a 5 sided "square" with yellow and black lines - next to the zoom icon). Click and drag to select all of NZ (zoom out enough first), then use the send to Device (under the transfer menu or the icon immediately right of the "map tool"). They rest should be reasonably straight forward. One more thing you may have to select the maps under the map tab first before using send to device (cant remember).

This was typed in a hurry so if you need any more help PM me (out riding tonight though).
