Hi all, For anyone that would like to visualize that the Open Location Code grid looks like, I took some screen shots of it overlayed with some imagery.
The smallest squares in the examples each have a 10 character OLC number/letter code. You will notice like every grid, the real world is not on a grid and many structures are in more than one grid. (Every grid system has this problem). The next up larger size of square is the square for an 8 character OLC number/letter code. It obviously groups a lot more buildings together, almost the small village scale, but again, they will usually be part in two, just like a structure. Anyway, thought folks who like to see things visualized in some way to help understand them might benefit from looking at what exactly we are talking about. I would like to see a way to have a better, more informative grid in all our tools, so like a TMS layer or support in OpenLayers or leaflet or something. The grid is based on WGS84 degrees already so anything that helps draw a graticule can just be adapted to have different major lines and list the shortened OLC instead of the degrees. https://twitter.com/BlakeGirardot/status/1028689726088388609 Cheers blake Cheers blake On Sat, Aug 11, 2018 at 2:55 PM, john whelan <[email protected]> wrote: > Open Location Code or Plus code is just a method of representing latitude > and longitude in a more human friendly way. > > It was originally created by Google but has been released under an open > licence. > > It is possible to set osmand to show coordinates as OLC.
