These layers are much like their counterparts, stat_identity, geom_point, geom_path, and geom_polygon, except they have a crs argument that ensures they are projected when using coord_sf. Stats are applied to the x and y coordinates that have been transformed.

NAD83 (EPSG:4269) Jun 30, 2015 · Gotcha, yea I think that falls into Leaflet's purview and I haven't seen any issues going from 4326 to 3857 (it's getting it out of some obscure projection that causes issues). If you are going this far, something else to consider in the transformation is optional simplification (default FALSE) via gSimplify , as this can greatly reduce file size.

NAD83 (EPSG:4269) When using gdalwarp to change the projection from EPSG:4326 to EPSG:3857, tilemill will then load the full geotiff, but the geotiff has a black strip down the center.

If these circles were drawn as ol.geom.Circle with a radius of 800000 (using EPSG:3857), they would all be the same size on the map but the ones closer to the poles would represent a much smaller area of the globe.
