OSGeo BC Meet-Up July 27 (during GeoWeb)

Martin recently announced that we will be holding an OSGeo British Columbia meet-up in Vancouver on July 27. We have timed this to coincide with GeoWeb; it falls on the Tuesday evening after the workshops are over and before the conference sessions start.

This session is open to all, so if you’re going to be at GeoWeb, or are in the area and want to hang out and eat pizza with some Cool GeoGeeks (oxymoron?) RSVP on the wiki!

We’re also looking for some presentation ideas; if you’ve got a burning desire, then please propose a topic on the wiki.

Kusam Klimb + GPS Watch + Google Earth = Kool

Please understand that an insane mountain challenge like the Kusam Klimb is about as far away from how I’d choose to spend my weekends as…. well… anything. Fortunately one of my co-workers, Ross Collicutt, is both a sports nut and a tech geek.

Ross

This past week was an interesting bit of synchronicity. First, Ross took advantage of a Costco sale on the Garmin Forerunner 405, a really interesting bit of sports gadgetry that gives you real time location and performance information including heart rate.

Second, Google released Google Earth 5.2 with considerable enhancements including elevation profiles and the inclusion of additional data (such as heart rate) in its GPS import function.

And third, this weekend Ross took part in the Kusam Klimb, a gnarly 23 km long trek over Mount H”Kusam near Sayward BC, featuring rugged conditions and a 1.5 km change in elevation. Make sure you check out this year’s conditions

After completing the event, Ross somehow managed to summon up the energy to post a link to his data upload on Facebook. I have to say, Garmin’s web-based visualizer is very nice! it combines a graph, a map, and gauges in a very clear and easy to use format.

If you visit the activity page, you will notice that below the map you can export as TCX, GPX, and KML files. Garmin’s KML file is actually a very nice time-enabled presentation, but it doesn’t include the heart rate or speed data. For this, you need to download the GPX file. The easiest way to open it in Google Earth is to drag it into the globe window. This pops up a dialogue asking what features you want in the generated KML, and then creates a new file in your Temporary Places.

Now the fun begins. Of course, the obvious first step is to click on the Play button in the time menu to watch Ross run the trail…

But that capability has been there for a while. What I find really interesting is the extra data that the GPX file brought along for the ride: heart rate, elevation, and speed. You can see the heart rate and speed (I think it may pull elevation from the terrain) by right-clicking anywhere on the track and choosing Show Elevation Profile. This gives you a cool interactive screen where you can display up to two variables, position your mouse anywhere along the graph, and see the information on the globe.

I have to admit that I have some reservations about this. The profile was very usable, but the design didn’t really fit with the rest of the Google Earth interface, and I would have liked to see all three data points (elevation, speed, and heart rate) at once. Fortunately, Google is well known for its incremental improvements, and I’m sure that it will get better over time.

Something else you can do with GPX data is create a Tour of your run and follow along with dizzying swoops and dips :) To do this, import the GPX as a linestring instead of a track, then expand the legend until you get to the Path and click on the “Play” button, and finally save the path tour.

You may need to play around with the Tour Settings in the Google Earth options a bit to get the correct zoom and speed, but eventually you’ll end up with something like the link below. Download the file, expand it in the Google Earth menu, and double-click on the Tour for some dorm-room-Quake queasiness:

Run Ross Run!

Whew. Time for some hard-earned relaxation! ;)

GeoWeb 2010 – Want worm? Act fast!

GeoWeb is one of the best generalist geospatial conferences I have been to. There is as much value in the calibre of attendees as in the quality of the technical sessions.

The last day for early bird registration for GeoWeb 2010 at reduced rates is June 20, so get cracking!

Snark: Perhaps the conference should have been entitled “The Importance of Metadata”? ;)

StackOverflow For Geo!

If you’re not familiar with StackOverflow, it’s a collaboratively edited questions and answers site for developers. With its wiki-like editing and community voting and reputation system, answers at StackOverflow (and its sister sites like ServerFault) are more complete, accurate, and accessible than any other technical resources.

With this understanding, I was excited to see that George Silva was involved in StackExchange’s incubator, and had put together a proposal for a StackOverflow for Geographic Information Systems.

GIS has long been more of a diaspora than an online community, with information stored across dozens of mailing lists, forums, blogs and other locations. Each open source project and proprietary application has its own set of resources, as do academic communities. Answers have been hard to find, and expert participation in these communities can quickly lead to burn-out. I believe that having a StackOverflow for GIS will help to solve these problems, and increase our individual efficiency working with GIS.

If you agree, please take the time to sign up for George’s proposal, and commit to being involved in StackOverflow for GIS!
