Hi Doug, What Emmor and Pablo are asking for is the same thing I need. Some of us would like to visualize the grid in our existing tools, which means either a KML, shapefile or a TMS end point to a transparent rendering of them we can use in our tools.
Generating one ourselves is a bit beyond many of us, well, at least myself. This same topic, OLC grid for overlaying also applies to our integration with other tools like Fieldpapers and the HOT Tasking Manager. So it would be great to figure out a good way make this possible. It is just a tiny bit beyond me. I love the examples you posted up thread, we just want the same sort of grid in our tools, kml, shapefile, geojson, TMS layers all work for us. Cheers! Blake For reference, the issues I created related to this on other projects I contribute to: https://github.com/hotosm/tasking-manager/issues/1158 https://github.com/fieldpapers/fieldpapers/issues/288 Cheers, Blake On Wednesday, March 7, 2018 at 4:32:49 AM UTC-5, Doug Rinckes wrote: > > Hi Emmor, > > You can turn on the grid display using the map at plus.codes/map/.
