Leaflet-Semicircle.

Allows drawing semicircles on leaflet maps.

It's an extension of Leaflet's L.Circle, and behaves like L.Circle if the a semicircle of almost 360 degrees is displayed.

Updated for use with leaflet 1.1.0.

Usage:

The plugin provides two ways to only display a part of the circle:

1. Use the options map and set startAngle and stopAngle.
2. Use setDirection(direction, size) to display a semicircle of size degrees at direction.

Example:

Live demo

Using options.startAngle and options.stopAngle:

L.semiCircle([51.5, -0.09], {
    radius: 500,
	startAngle: 45,
	stopAngle: 135
}).addTo(map);

Draw the same semicircle using setDirection(direction, size):

L.semiCircle([51.5, -0.09], {radius: 500})
	.setDirection(90, 90)
	.addTo(map);
