Leaflet.GreatCircle

Draw accurately projected circles on Leaflet maps.

Why?

The existing L.Circle functionality draws a plain geometric circle on the map. However, due to the nature of map projections, this in not an accurate way to represent a circle on a sphere.

Our shape computes the multipolygon boundary that includes the points on a globe having a distance to "center" less than "radius".

We determine the lat/lon of each bearing around the compass at that distance using the the geodesy library by Chris Veness.

Installation

Since leaflet doesn't play well without a browser, you're likely using bower. In this case, just bower install Leaflet.GreatCircle.

We do also support node, though, so you can npm install Leaflet.GreatCircle.

Usage

L.greatCircle(centerLatLng, radiusInMeters, { fill : 'red' }).addTo(map);
