park has been reworked as closed area; watch this area of water to be sure it renders on top of park properly - it may be advantageous to "cut it off" of river

Calgary open data Land Use Poly, if taken as highly accurate (and there is good reason to believe it is) suggests that the features around here, as they appear on 2017-11-22, are quite accurately positioned & the Bing image from early 2017-11 has poorer accuracy than previous Bing image
