Uploading from the GPS

Lindsay (eldest son) and I went Orienteering at Oakview, which is a property about 20km west of Armidale on the Bundarra road. We did a 3.5km “Short Red” course.

The GPS was carried to track our path. I think this is becoming a common enough sight at Orienteering events these days that people no long immediately assume you’re cheating.

Back at home the GPS is plugged into the (Ubuntu) PC via its own serial cable and a USB-RS/232 converter. To upload the track data:

gpsbabel -t -i garmin -f /dev/ttyUSB0 -o kml -F FILE.kml

There are usually some breaks in the path due to the device losing contact with the satellites. Currently a text editor is used to rudimentarily merge them into a single path. The resulting file can be imported into Google Earth to (re)view the path.

It can also be uploaded to Google Maps to make a sharable map.

In addition, there are sites like gpsvisualizer which allow you to upload the file and have it converted to various formats – including an elevation profile:

Note that our 3.5km course (measured by straight lines between the controls) ended up being about 4.5km.

Stitching Videos

Heavy overnight rain swelled the creek on our property and we went for a walk with the digital camera to take photos. Three videos of the flow were also taken.

Son #1 seemed a bit bored so he was set the task of finding a program (for Ubuntu) to stitch the three videos together into one – along with some static text between each one. He found Kdenlive and it, and he, did a brilliant job:

In case the embedding doesn’t work, here’s a link to YouTube: Toms Gully Creek near Boorolong Road – 31 July 2010.

The creek has a mostly perennial flow, but will stop flowing during extended dry periods – such as one that only finished a few weeks prior. It was certainly a stark contrast.

Toms Gully Creek is a tributary of the Gwydir River including the Copeton Dam which is at 6% capacity. Hopefully this will knock that up a bit.

INX Reaches 1.0

In my (copious – I wish) spare time I contribute in minor and probably annoying ways to a project called INX which stands for “Is Not X” (and is pronounced ‘inks’). It’s a Linux distribution designed to teach the command-line and some of its tools in an easy and fun way.

Today it reached its version 1.0 release (click on this text to learn more).

Congratulations Peter!
