Bit old these days, although maybe that makes it cheaper, but I love my Garmin 
Geko 201.  Waterproof, takes two AAA cells.  Reasonably accurate.  Robust.  
Well-implemented features.

I'd like to know what's current, but I am always extremely happy when I use my 
Geko.

Best wishes,

Andrew

I am also very happy with my Garmin eTrex Vista HCx, allthough it
doesn't feature a recent GPS chipset.

On the german list there is a discussion at the moment about current
GPS-loggers (+ Bluetooth-connection to use them as GPS dongle for other
devices) and their chipsets.
Very interesting (and new) devices that have been mentioned there:

http://www.kowoma.de/gps/geraetetests/wintec_wbt202/wbt202_p1.html
(using u-blox 5)
http://www.kowoma.de/gps/geraetetests/iblue%20747A+/iblue747A+.html
(MTKII-chipset)

The pages are in german but you can find other reviews of these devices
via Google.

Depends on what exactly you are looking for. A device with a "big"
screen for map display and navigation or just a GPS-logger with
pushbutton to create waypoints ...

Best regards,
Jannis

I still enjoy my Columbus/Visiontac V-900. It's a GPS data logger
which records georeferenced audio notes. It's quite compact, and the
battery lasts from morning to night (rechargable).

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.

The Columbus V-900 is $89. Charges via USB, records on a micro-USB,
has a button to take a waypoint, or another button to press to record
a georeferenced audio note. Gets a fix within two seconds if the
previous fix was less than two hours ago. It's only 1cm thick, so it
slips nicely into a pocket.

I've been eying the Columbuses. Do you know what the difference is between
the V900 and the (newer) V990?
One feature that I particularly like about the 990 is the ability to switch
to passive mode (GPS off) when the internal accelerometer doesn't detect
movement or the device loses its fix for more than a few minutes. That
would mean you could just forget about switching the logger off and on.
Does that really work? Also the built-in voice tagging seems nice, anyone
tried that for mapping?

What about a camera with built-in GPS?  That way you can make photo
documentation of the progress at each site with a timestamp and
geostamp[1].  Many cameras also record audio, so you could have
timestamped, geostamped audio too although I'm not sure how
independent/integrated the GPS in such a camera is.  Remember, when taking
a picture *of* the site to adjust for the offset *to* the site, or just
take a picture straight down or something.

A random 30 second search brought up the Casio Exilim EX H20G for $199 at
Amazon.

Another option is a smartphone with a built-in GPS, but maybe they are
expensive.

Best wishes,

Andrew

[1] I'm not sure if anyone uses the expression "geostamp" although
Wikipedia assures me it exists.

as far as I know, the accuracy of camera and cellphone GPS units are not
enough - we are talking of toilets in row houses in villages, a few
meters apart. (I may be wrong here).

I used to map with the V-900 until the plastic case broke on the edge with the
LED. I know of two disadvantages.

1. You always needed a charged battery as acurrency droped a lot if there was
not much power left.
2. It is only possible to log either audio or gps-position at once. E.g. you
can only log audio while stopping, otherwise you will miss parts of the track.

Maybe that changed as I used version 1.

The Canon Powershot SX230 is a good option since you can put open source
firmware on it. The problem is the accuracy of camera GPS units is pretty
bad, and battery life can be an issue. You're better off with a separate
unit and then syncing them up.

+1, I guess it is similar as with smartphones (AFAIK the main problem
is the antenna): I am often taking fotos with an iPhone and record the
track in parallel with a Garmin. 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.

Martin

Re: [OSM-talk] handheld gps unit

2012-04-23 Thread Spod
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.

It sleeps until you start moving again.

Looking at the specs, the V990 doesn't have bluetooth, has a
longer-life battery, and a more sensitive GPS receiver that gets a fix
faster. It also doesn't come with a micro-SD card, nor a wall
charger. Otherwise it looks identical but $30 cheaper.

 > Also the built-in voice tagging seems nice, anyone tried that for mapping?

It's supafine! It's my favorite method of mapping. When you use my
columbus-to-gpx.py converter, it produces a GPX file with voice file
links that show up as audio bubbles in JOSM. Click on the bubble and
it plays your note.

It has some flaws, but the audio mapping is SO much fun that I ignore
them:
  o The plastic surrounding the corner LED tends to crack.
  o There's a slight delay after you press the button before it starts
recording.
  o It chops off the end of your audio note, so you have to release
the button a few milliseconds after you stop talking.
  o It stops recording the track while it's recording your voice.
  o You have to pull the micro-SD to get the data off of it.
  o It has a bizarre log file format. 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. Then it goes deaf, lights up the corner light white
and then turns off. If I turn it back on, it quickly gets a fix
and starts recording again. Takes about fifteen seconds total.

Like I say: flaws and all, I'll buy another one when this one dies.

There exists an extra JOSM-plugin for the Columbus which works nice

I have only mentioned the cons., so far and did not talk about the pros:

I liked it. Audio mapping is the best. It is much cleaner than talking photos
and way faster than typing comments.

The device is small, light and its battery lasts very long.

Overall I, even knowing the flaws, I would still recommend it.
