When you later compare the geotags of the phone with your GPS-tracks from the Garmin you will see much butter accuracy from the dedicated device, but the phone has the advantage of storing the direction (orientation) very precisely. In JOSM you can later associate the GPS-positions from the separate track to the photos and the cool thing is that the orientation data from the phone is kept in the photo together with the new position data. cheers, Martin ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] handheld gps unit
I have the VisionTac VGPS-900 (which is the same as the Columbus V900), and am very happy with it. 1) For me, the audio recording is a vital feature, especially when mapping house numbers, shops, POIs, turn restrictions etc. Having used this a lot, I can't see myself going back to a logger without audio recording! I have _not_ had any problem with the audio recording function stopping the recording of GPS points - it seems to work perfectly OK for me. 2) Accuracy is good. 3) Seems to get a fix quite quickly, even when you've moved a long way with it turned off. 4) Battery lasts ages. 5) The onboard software does quite a lot of interpolation/extrapolation, so that you can sometimes see the track overshoot when doing a sharp turn. I've seen a review online somewhere that shows this happening with all of the 'high sensitivity GPS-receivers though, so not unique to the V900. 6) As someone else mentioned, there is no USB data connection (the USB port is for charging only), so you have to take out the microSD card to transfer the data to a PC. Mine came with a USB microSD reader, so I don't see this as a problem. As far as I know, the V900 does not have any internal accelerometer, so if the V990 has one, then that's a difference. -- View this message in context: http://gis.19327.n5.nabble.com/handheld-gps-unit-tp5651586p5660208.html Sent from the General Discussion mailing list archive at Nabble.com. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

It's a combination of comma-separated AND null-padded fixed-length fields. SRSLY o It's so small and lightweight that it's easy to leave in your pocket when you do the wash, and it's not waterproof. I only washed it once, but once was enough. o It writes files into the root filesystem, and when you fill up the vfat directory space, it crashes. o Sometimes (I haven't figured out when) it crashes when I push the record button.

[OSM-talk] handheld gps unit
For what's worth: I have been using for the last couple of months a
new-series etrex (etrex 30). This is the first Garmin handheld with a chip
also for GLONASS. I have done some precision checks with the device mounted
on the bicycle handlebar. Running with GLONASS and WAAS enabled I easily
achieved precision ranges of the order of one meter under open sky and with
good weather.
The checks consisted in cycling along narrow roads and comparing outbound
and return track whith high-resolution well-aligned satellite pictures.
The precision is good, but my overall judgement of the device is not so
clear. The user interface is not very intuitive, to say the least, the
manual (as usual with Garmin) is lousy. And the new etrex is completely
different from the classical etrex (in my case Legend HCx), in particular
they left out the beautiful, but little-known capability of the old etrex
to navigate downloaded tracks with the fantastic TrackBack feature, with
the big red arrow and the acoustic signals when approaching a turn in the
track. That's all gone.
I have written up quite a lot about using both devices, but it's all in
Italian, I'm afraid.

the lack of unification on how 'romanized' language tags are used and

We strongly believe OSM should get behind and use BCP 47 as

Would be great to get the tagging guidelines accordingly.

Do you know how this compares to the newer touch screen Garmin devices
(Dakota, Oregan, Montana)? I know that upon release the GPS performance
(read Accuracy) of the touch devices was below the Vista HCx.
Wondering if they could fix that via firmware upgrades or even
improvements to the hardware.
I really liked my Vista HCx, because of the very fast time to fix, the
high accuracy and the fact that it actually had a scrollable map
(something the Geko is lacking). But then the usability with that small
joystick was just... bad when using the map.
