Chicago #50

Open MDKaiser opened 2 years ago

MDKaiser commented 2 years ago

Most places work, but Chicago produces this error: ERROR:shapely.geos:TopologyException: depth mismatch at at 448510 4637400

Using a slightly modified version of the circular example with a radius of 2500

This seems to be the same as #27 where the issue was in Seattle (47.606292888654316, -122.33203340169379), radius = 5000.

In that case the issue seems to be to do with a footpath around 47.649699, -122.306248 (which was at the edge of the map) but if centered on the footpath it doesn't have an error? So maybe it's to do with only getting part of the geometry?

@MDKaiser 448510 4637400 are the UTM coordinates using this site you can see that the coordinates are 41.886853, -87.620628. Is this near the edge of your map as well?

It is.

I've come across a few more of these instances by now. They're rare, but not unique.

I had a similar issue with Milan, Italy, wrote a workaround to skip it in https://github.com/marceloprates/prettymaps/issues/27
