I'm out on holiday soon to Arizona, so we've been looking for ways to geocode
the photos we'll be taking and get a record of our route. I use a Mio A701
phone which has built-in GPS, and this time we'll be using Tom Tom in the USA
rather than Mapopolis. The problem with Tom Tom Navigator is that it doesn't
keep a track log, and there doesn't seem to be any plugins to allow it to do so.
So here is the solution I've been experimenting with over the weekend.
On the
PocketPC:
- Make sure the GPS Intermediate Driver is enabled, on the MIO there
is a built-in "GPS Settings" utility where I have it set to COM4 and "Manage
GPS automatically"
- Use the GPS2Blue
utility. Make sure it's set to GPS on COM4, 4800 baud, with logging
only of GGA/GLL/RMC/VTG NMEA, and select 'Log processed raw data...'. You don't
need to enable the "2blue" bit, we're just using it to write the tracklog.
- Make sure your camera has a date and time that is close to the one being shown
by GPS2Blue from the satellites
- Start TomTom. Make sure it's also set to COM4, 4800 baud. This
will work because the GPS Intermediate Driver is opened by GPS2Blue. You
can't start TomTom first, but you can exit GPS2Blue and leave TomTom
running.
- After finishing you end up with a NMEA track log with an hour of logging
taking up about 1.6Mb. Transfer it to your Fedora machine.
On my Fedora machine:
- Use gpsbabel to convert the NMEA
track log and clean it up a bit. I used:
gpsbabel -i nmea -f GPS_2008-03-03_122630.log -x discard,hdop=10,sat=5 -o gpx -F out.gpx
- Use gps2photo.pl to
add the geocoding to your images. This script looks at the time and date the
photo was taken and tries to match it up to an entry in the tracklog, so you
may need to play with the timeoffset to
deal with timezone differences. Although we have snow, being in the UK in the Winter has
it's advantages as we're UTC+0, so I just used:
gpsPhoto.pl --geoinfo=osm --dir ./ --gpsfile out.gpx --timeoffset 0 \
--city=auto --sublocation=auto --state auto --country auto --kml out.kml
The exif metadata inside each jpeg now contains the approximate co-ordinates
of where you were when you took the photo along with a guess of the location
(city, country, etc). You can load out.kml into GoogleEarth to see the
tracklog and photos on a map. If you've allowed Flickr to read the location data
from exif then uploading a geotagged photo will automatically place it on a
map. (Make sure you consider the consequences before enabling that option or
you may end up unintentionally leaking information like the location of your
friends houses or parties you've been to). Here's a quick pic taken in the snow today to test it out:
Nalin gave a great presentation in the last summit slot about single sign on. One of his slides read simply "Passwords Suck. More Passwords Suck More". I think this is a useful phrase that I am going to now subvert for a short rant:
American Airlines Experiences Suck
More American Airlines Experiences Suck More
First was the debacle which was a 7 hour delay getting to Nashville after a flight was cancelled. Now, at 9pm the day before my 6am flight from Nashville to London tommorrow they cancel my flight and are unable to get me to London in time for my Monday meeting. So I miss my meeting and total for the week I'll have had 18 hours of delays. Although perhaps I shouldn't blog this until I'm home as I'm still in Nashville and, nice that it is, don't want to spend another year here. So thats four out of my last six AA trips that have gone significantly wrong, and I only used AA this time because I wanted to upgrade and had miles left.
However, rant aside, this trip was all about the Red Hat Summit. I was pleasantly suprised by how smoothly it ran and how useful it was to have face-to-face meetings with some of the people I interact with daily by computer. There's a few cool things that the trip acted as a catalyst for, but you'll need to wait to find out ;) I tried to speak to many different attendees over breaks in the days, and consensus was positive with all the first-timers wishing to attend again in the future.
a few of my photos from the summit
After a busy day yesterday at the Summit we partied over at the Wildhorse Saloon. Popped out for an hour with a couple of colleagues to grab a few local geocaches, and saw some sights in Nashville we'd otherwise have missed.
After completing all my presentations yesterday I was able to relax at the conference party. Perhaps we relaxed a little too much.
Just back from my two presentations and I've uploaded the final versions (which replace the ones distributed on the conference CD).
I did eventually make it to Nashville, although with a 7 hour delay in Chicago. Yesterday was mostly catching up and a little local geocaching.
Earlier today we made public a new service from the security team: OVAL patch definitions for Red Hat Enterprise Linux 3 and 4. Some summary information is available at our OVAL FAQ, or if you are at the Summit pop along to my talk starting in about 45 minutes.
Previous flights to the US have all ended in disaster so I've been avoiding travelling for some time. However this morning I set off from Glasgow to Nashville for the Red Hat Summit. I'm giving a couple of security presentations on Wednesday. Except that's Glasgow to Chicago and Chicago to Nashville. And the Chicago to Nashville flight got cancelled due to Air Traffic Restrictions (whatever that means it means AA didn't want to take responsibility). Then the bad weather hit and, well, I'm still here 5 hours later, with no sign of the last flight of the day being actually able to leave. Fortunately I flew out a day earlier as I kind of predicted the risk that this sort of thing would happen.
Hot isn't enough of a descriptive word for Karslruhe this week; 34C with no aircon on the show floor or hotel. I'd planned on taking a few hours out to go geocaching but so far don't fancy waking the mile round trip. Instead I managed a couple of webcam caches yesterday and I'm waiting for the weather to break. Did a couple of talks today (for partners) but the big FudCon talk is tommorrow morning, which should be more fun. Got to play with a Nokia 770 (shame it doesn't have a nice desktop stand charger), and find out some more about Xen. Time to go find some more nice Eis.
Off to Germany tommorrow for LinuxTag, FudCON2 and a few presentations. Unfortunately I get the first talk on Friday morning, just after the social event on Thursday night. Or it could be fortunately - this means that I could possibly get away with lower quality slides if the event goes well and everyone drinks lots. As some light relief today I found some gummi worms to photograph for my "Linux Worms" slide and some cute playmobil penguins. I'm looking forward to some real Haribo made in Germany, rather than the inferior "made in UK" versions I bought in Macro. I'm also looking forward to visiting Deutsche Bundesbank to exchange all my DM cash into Euros!
Out in the USA for a week and I'm making myself at home. I'm watching "America's Funniest Home Videos" (which kind of makes me wonder how you could possibly find less funny videos). I'm drinking $1.25 bottled tap water. Really, this stuff actually says on it that it's taken from the public water supply. But I went and bought loads of Haloween Candy from Target, and the hotel has free wireless internet access, so it's not all that bad ;)
