# GeoCircle

GeoCircle[loc,r]
is a two-dimensional GeoGraphics primitive that represents a circle of radius r centered at the location loc on the surface of the Earth.

GeoCircle[loc,r,{α1,α2}]
represents a sector of a circle from bearing to bearing .

## DetailsDetails

• A geo circle with center loc and radius r is defined as the endpoints of all geodesics of length r starting from loc. Specifying bearings and restricts the set of geodesics.
• The location loc can be specified either as latitude and longitude coordinates in degrees, GeoPosition[], or as a named geographical Entity[].
• The radius r can be given as a Quantity length or as a number in meters.
• Bearings and are measured clockwise from true north and can be given as Quantity angles, as numbers in degrees, as DMS strings, or as named compass points like or .
• GeoCircle[loc] represents a geo circle centered at loc, with an automatic choice of radius.
• is equivalent to .
