Two years ago, I took a picture of the boardwalk in Kokanee Creek Provincial Park. This path links the creek with the the spawning channel and the Nature Centre. I noted then that plans were underfoot to replace the boardwalk with something offering greater accessibility. The earlier picture I took is shown first. The new boardwalk opened today and a similar view of it appears below.
This is the boardwalk as it was. At the top is a bridge over the spawning channel which also leads to the Nature Centre. At the lower left the boardwalk winds around to the bridge over Kokanee Creek itself. At the lower right is passage along the spawning channel. This is all now replaced.
The new boardwalk is similarly arranged. At the top is a bridge over the spawning channel which also leads to the Nature Centre. At the lower left the boardwalk winds around to the bridge over Kokanee Creek itself. At the lower right is passage along the spawning channel. However, the boardwalk is much broader and more gently sloped. It is fine craftsmanship which allows easier and safer passage, along with potentially better views of the spawning kokanee.
The Park has done a fine job of offering both access and passage.
Do not walk on the boardwalk when wet with crocs on!!!
Mary, I rather suspect that advice is only applicable for latitudes at least 20° south of here.
Hi Alistair:
Could you explain how your got these shots? From an airplane? or some fancy technological tool?
Thank you
Jean
Jean, each above image is a polar (zenithal) stereographic projection of image data collected by a full-sphere camera held about three metres above the intersection of the three paths.
Here are two other projections from the same camera data. First, an equirectangular projection, where the zenith is spread across the top, the nadir along the bottom, and one side wraps to meet the other. This image shows everything that is possible to see in any direction from the camera position.
Then another polar stereographic one, but projected from the nadir.
However, does this represent a fancy technological tool? Well, all photography involves some type of projection. Most often what cameras use is the rectilinear projection. Yet, all of these mappings have been known and used for centuries in the cartographic community. What has changed is that now computers allow amateurs to easily use the techniques.
Alternatively, you can assume that it is all magic following Arthur C. Clark’s third law that “Any sufficiently advanced technology is indistinguishable from magic.”
As always, beautifully done Alistair.
