only 99 waypoints from NMEA file? - snedyan - 29.09.2007

Thanks a lot for this great software and for the Linux version. Wink

I use the RouteConverterLinux.jar version.

Just two little questions:
- the first one is about a conversion of a NMEA file in .kml file for Google Earth 4.2: I have a NMEA file with 300 waypoints. RouteConverter shows only 99 waypoints. Is it due to the fact that for some intermediate waypoints the direction is the same then intermediate waypoints are not counted? (Final result on Google Earth seems good compare to the trip I have made).
- the second is about the possibility to show a map: it does not work on my system using Linux version. Could you help ? (Ubuntu 7.04).

Thanks again Wink

Hi snedyan,

the 99 waypoints problem seems odd. NMEA and Google Earth 4.2 do not have a restriction on the number of waypoints. But... RouteConverter ignores waypoints without coordinates which a lot of GPS logger produce if they cannot compute a position. Could you send me the NMEA file to check what's going on?

Regarding the map view, I depend on the JDIC project. Please download the latest (0.9.3) sources and try to compile them on your platform. If that succeeds replace the binaries in the jar

23.06.2005 09:25 455.336 libmozembed-linux-gtk2.so
23.06.2005 09:25 9.467 mozembed-linux-gtk2

with your compilation.

If you have any questions post them here. I'll try to help.

Thanks for the reply Wink

Please find attached the NMEA file.

Concerning the compilation for obtaining the map, I will try (and to be completely honnest: I will try to try Tongue

due to a little trouble to find some free time).

Thanks again,

Hi Snedyan,

I've found the missing waypoints... It's not a bug it's a feature!

Take the first 2 NMEA sentences of your example file:
$GPRMC,114911.000,A,4824.8998,N,00244.4064,E,0.0,331.0,290907,,,A*69
$GPGGA,114911.000,4824.8998,N,00244.4064,E,1,10,0.8,99.0,M,,,,*35

They contain the same position information, so RouteConverter aggregates the information to one position which contains the information from both NMEA sentences.

I implemented that to reduce the number of positions to those carrying real information.

A possible nice feature is also:
Some way to beautify the route. Means even when using something like SONY GPS CS1 there are many waypoints (every 5 secs one) and some of them are very suspect (mesurement-mistakes,...).

So maybe there is a feature where we can eliminate (via avg-functions,...) this errors?

Yes, push the button with the blue line ("Selects duplicated positions of the position list") and a dialog comes up which allows to

Select all duplicate positions within a distance of XXX meters of their predecessor
Select all position such that at least XXX meters lie inbetween the remaining positions
Select all positions but every NNN th position

After selecting the positions, you may delete (or move) them.

Is that what you where searching for?
