BC: Power up your Vote!

I gave this spiel at the Victoria GeoGeeks meet-up last week, but it’s worth giving to the world at large: if you want your vote to count in choosing your representatives, exercise it at every opportunity! For those in the USA, that means participating in primary elections, and for us in British Columbia right now that means participating in the party leadership contests.

When you participate in early elections like primaries or leadership races, your vote gets more powerful.

In the last British Columbia election (2009) 1,651,567 people voted to choose the government. But they didn’t get to choose the Premier, they just got to choose the party or local candidate. The next Premier of BC will be the leader of either the BC Liberals or the BC NDP. The combined membership of those races will probably be on the order of 60 thousand. So a vote cast in the leadership contests is about 27 times more determinative of who will be the Premier than a General Election vote.

Who wouldn’t want their vote to be 27 times more powerful?!? But here’s the rub: only party members get to vote.

For the BC Liberals, the election will occur on February 26, but the cut-off for membership is 5PM on February 4. You can sign-up online here ($10 annual membership).

For the BC New Democrats, the election will occur on April 17, but the cut-off is midnight on January 17, and you can sign-up online here ($10 minimum donation).

If you live in BC, this is your chance to have an outsized influence on who makes the decisions for our future. Get to it! I have!

We interrupt this geeky spring...

To do something completely different. British Columbia, my fair home, is in the midst of an odd period where both major parties are having leadership races. The race for my party of choice (the NDP) has just gotten started, and I believe that pitching in early for what you believe in is a way to have maximum effect. So I’m spending my spring working as much as possible for John Horgan. John’s someone who reflects my belief nobody has all the right answers, and he’s someone with the personal skills (that I envy) to both listen for the answers and bring folks together around a common direction. And he’s fun to be around, which is a nice bonus.

Unfortunately for PostGIS, time doing campaign work takes from time spent on PostGIS 2.0, so unless another PSC member has an equal and opposite infusion of time to mine, things will slow down a bit for the next couple months. I’ll still be going to the Montreal code sprint though: some things are sacrosanct.

Victoria GeoGeeks!

The Victoria geo-geeks are meeting again next week, on Thursday, January 6, at 6pm at the offices of Latitude Geographics. We’ll be hearing from four speakers, on the topics of Google Fusion Tables and Open (Geo) Data in Government.

  • Google Fusion Tables, Intro and Demo - Josh Livni, Google Outreach Engineer (30m)
  • Open (Geo) Data in BC - Herb Lainchbury and Greg Lawrence (25m)
  • Open (Geo) Data Rebuttal - Mark Sondheim (5m)

Hope to see all you Victoria geo-geeks there!

Removing Complexities

My co-worker Alyssa Wright just asked me an interesting question: Vancouver Island is a pretty crinkley island, how would we simplify it to remove the crinkley bits?

Original Island

Notice the big fjords and other fine work by Slartibartfast. ST_Simplify will not do what we need, since it removes redundant vertices within a tolerance. So the fjords will have fewer vertices, but they’ll still be there.

However, it turns out there is a solution, and I didn’t even need a long walk in the snow to figure it out. If we buffer by a large amount, then reverse the buffer by the same amount, we’ll get something that has a similar shape to the original, but without the crinkly bits.

Buffered by 4km

Buffer out, and the crinkley bits get melted away. But now the island is too big. So buffer inwards.

Negative Buffer by 4km

And now we have something we can use. We could now even run ST_Simplify on this result to drop some unneeded vertices and make it smaller yet.

Simple Island

Looking closer, you can see how we have melted away all the crinkley bits while still following the original (mostly). Note that the new shape is still a strict superset of the original.

FOI @ OpenGov BC

This is what I did last Wednesday while recovering from my Japanese jet-lag: panel wrangling at OpenGovWest BC. Probably the easiest moderating session I’ll ever get, four FOI superstars, just wind them up and let them go.
