    Mapping!

    Presently I’m using aerial photography to produce a map of local cycle ways and walkways.

        Its a lot more complex than it sounds. I have a post grad in geo spatial intelligence, even though its not something I do professionally.

        These maps are stylised, meaning that the location of some things in some cases is moved slightly to improve readability. For example, I want the map to cover the entirety of my small city so the scale has to accommodate that. However, in some areas like beach fronts and tourist precincts there’s a lot of important features to include, which the scale just doesn’t really allow for. So you take some editors license to move things in a way that fits everything, but no one reading your map would think “Hey that path is supposed to be 30m to the west according to this map.”

        For this reason the whole thing is more of an exercise in graphic design than it is one of geo spatial manipulations. Im using inkscape to create the map but i have qgis open alongside for things like street names and suburb boundaries.

        The photography im using as a background on which to draw streets and paths is published by our state government. Its a tiled view of the entire state compiled from aerial surveys by plane. The resolution and quality available is truly beautiful.

        The thing about this process which is truly captivating is that despite living her for 40 years, and growing up here as a curious and nosy scallywag, I’ve discovered so many little things in my area I didnt know existed. For example, there’s a network of paths that runners use behind a lake that I always thought was just a swamp.

        There are also features I suspect may be similar to “crop lines” - vegetation growing in a different way due to man made features beneath the surface. In this case, fish traps constructed by first Australians perhaps hundreds of years ago. Or maybe its not that at all.

          That’s really cool! What a neat project!

          Certainly not to this degree at all, but I do love having a satellite or aerial view to just look around my area. I recently found there’s sprint boat races on a small man made course nearby and I’m excited to go check it out!

          Good luck on your future endeavors and I hope you find some more neat stuff :)
