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

Philipp_Steigenberg1 · February 21, 2008, 4:06pm

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!!!

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???

The gpsbabelproblem is solved. I attach the correspondence. Neverthelesss I still hope for answers of the GRASS-related questions.

Grid was added after 1.3.2.

    Do I have to install something else?

The binary distribution is for Fedora. Users of Suse or Debian-based distributions like Ubuntu would be best served by |rpmbuild --rebuild whatever.rpm' | on the source rpm.

Or forgo the rpm completely and build from source.

see the v.in.garmin help page about running 'gpstrans -s' first to set
output as DDD.

I have found that gpstrans can sometimes be buggy (tracks offset by 1
relative to timestamp), so you may prefer another solution if you need
exact timestamps.

The last attribute is not being split into two columns for some reason.
What model Garmin and what version of gardump do you use?
can you send a few line sample of the result of running gardump from
the command line to the list as an attachment?
do you have an idea what the #id= means?

I am rather too busy right now to spend much time on this, or even to
monitor the mailing list closely, but I hope someone else might be able
to have a look and see the problem. If not, please file a bug report
with as much information and sample data as you can and I'll eventually
get to it. Or jump into the shell script yourself- it's a pile of sed
and awk processing.

Hamish,
thanks for helping!

Im very sorry that I confused you.
The #ID 25 is just a comment to tell you that the third column contains the ID.

I tried a little more to get my data from GPS. No that I installed the newest version of gpsbabel it also works that I get the aptitude-values using v.in.gps.babel. My goal is to generate a DTM from this data, so I'm happy now. - And - as you - I am also to busy to spend more time on this.

sincerly
Philipp

note GPS positions will be about an order of magnitude less accurate in
the vertical than in the horizontal, don't be surprised if a standard
handheld GPS differs in the vertical by +-20m. also note that the
elevation given is height above the WGS84 geoid, not above sea level.
