Method Summary

Modifier and Type	Method and Description
static ai.nextbillion.kits.geojson.Polygon	circle(ai.nextbillion.kits.geojson.Point center, double radius) Takes a Point and calculates the circle polygon given a radius in degrees, radians, miles, or kilometers; and steps for precision.
static ai.nextbillion.kits.geojson.Polygon	circle(ai.nextbillion.kits.geojson.Point center, double radius, int steps, java.lang.String units) Takes a Point and calculates the circle polygon given a radius in the provided TurfConstants.TurfUnitCriteria; and steps for precision.

circle

public static ai.nextbillion.kits.geojson.Polygon circle(@NonNull
                                                         ai.nextbillion.kits.geojson.Point center,
                                                         double radius)

Takes a Point and calculates the circle polygon given a radius in degrees, radians, miles, or kilometers; and steps for precision. This uses the DEFAULT_STEPS and TurfConstants.UNIT_DEFAULT values.

Parameters:

center - a Point which the circle will center around

radius - the radius of the circle

Returns:

a Polygon which represents the newly created circle

                                                         java.lang.String units)

Takes a Point and calculates the circle polygon given a radius in the provided TurfConstants.TurfUnitCriteria; and steps for precision. This method uses the DEFAULT_STEPS.

Parameters:

center - a Point which the circle will center around

radius - the radius of the circle

units - one of the units found inside TurfConstants.TurfUnitCriteria

Returns:

a Polygon which represents the newly created circle

Takes a Point and calculates the circle polygon given a radius in the provided TurfConstants.TurfUnitCriteria; and steps for precision.

Parameters:

center - a Point which the circle will center around

radius - the radius of the circle

steps - number of steps which make up the circle parameter

units - one of the units found inside TurfConstants.TurfUnitCriteria

Returns:

a Polygon which represents the newly created circle
