The blog that wants to go obsolete
Last time, one of the questions was, which digital elevation model (or DEM) should I use. Initially I worked with the relatively low-resolution DEM derived from the 20m contour lines.
Of course, Auckland Council has had a 1m DEM derived from lidar data for a while. There’s also a digital surface model, which doesn’t follow the ground level, but which models the ‘surface’ visible from above. You’ll see the buildings and tree tops on that one.
And now, back to that other interest of me: maps.
One of my favourites is maps showing the relief in the landscape. There’s the relief shading in Google’s terrain maps, or the height contour lines on topographic maps. But I find both hard to interpret. While both are good at showing the local relief, it’s difficult to make out the bigger picture. What I wanted was a map which uses a simple color map to represent elevation.
Let’s make one.
Auckland transport is doing another small consultation, this time to figure out how buses coming from New North Road (the successors of the current 221, 223 and others) will return to the west.
The 3 options for the return route are shown in dashed lines. The orange lines show a new proposed route for NEX buses.
One of the classic dilemmas in city planning:
Well, I’ve left the building. I’m now living in the ’burbs. Like normal people.
And now for some good news: the NZTA is investigating road user rules for people walking and cycling. In other words, this Unique Piece of Kiwiana Heritage is going obsolete.
So I submitted on this proposal for whatever they’re building on Queen Street in Northcote Point. Basically my previous post, but a more polite version. So a few weeks ago I got the feedback report in my inbox. And a distinct sense of déja vu.
So the option with the double lane speed bump it is. Actually, nobody really wanted any of the 3 options, but as a politician would say, we have to do something.
