[GRASS-user] gpsbabel and garmin_txt, v.in.garmin, v.in.gpsbabel - with garmin etrex

[Philipp Steigenberger]

Hello,
anyone has expierences with gpsbabel?

I try to import data from a garmin etrex gps

I use this command:

gpsbabel -t D9 -i garmin -f /dev/ttyUSB0 -o garmin_txt,grid=ddd,prec=6 
-F trackpoints.dat

cause I read in 
http://www.gpsbabel.org/htmldoc-development/fmt_garmin_txt.html
that one can specify a grid-parameter:

#########################################################################
grid option

Write position using this grid..

This value specifies the grid to be used on write.

Table 3.1. Grid values for garmin_txt
# idx	short	file-header	sample
0	ddd	Lat/Lon hddd.ddddd	S26.25333 E27.92333
1	dmm	Lat/Lon hddd°mm.mm	N33 56.539 W118 24.471
########################################################################


unfortunately it doesnt work.


the gpsbabel --help tells me
########################################################################
	garmin_txt            Garmin MapSource - txt (tab delimited)
           date                  Read/Write date format (i.e. yyyy/mm/dd)
           datum                 GPS datum (def. WGS 84)
           dist                  Distance unit [m=metric, s=statute]
           prec                  Precision of coordinates
           temp                  Temperature unit [c=Celsius,
########################################################################
NO GRID-PARAMETER!!!   :o(

so whatever grid-parameter I set i get a file-header like

Grid    Lat/Lon hddd mm.mmm'
Datum   WGS 84




I need the grid #idx=1 (ddd) to sort and filter the points before I 
import them to GRASS. I tried different settings but I got everytime the 
dmm-format.



Finally I want to project the data in Gauss-Krueger-Projection 
(Transversal-Mercator).

I know that GRASS contains v.in.gpsbabel and v.in.garmin. Its very nice 
that I get the data immediatley in Gauss-Krueger-coordinates. But using 
this tools it doesn't work to import altitude-data and other 
informations as well.

Is there a posibility to get Gauss-Krueger-Data just by using gpsbabel?





Between the ++++ I pasted the outputs of different attempts of 
v.in.garmin and v.in.gpsbael.  Jump to the END if you want to save 
time!!! ;)

Does not do anything...

END






The solution I get for me is to connect the output of v.out.ascii and 
also the output of gpsbabel (both have 6792 points) paste them together, 
use awk and so on and import it enentually with v.in.ascii -z

But this cannot be the final solution... can it????


Cheers

Philipp
