@turf/ellipse

ellipse

Takes a Point and calculates the ellipse polygon given two semi-axes expressed in variable units and steps for precision.

Parameters

• center Coord center point
• xSemiAxis number semi (major) axis of the ellipse along the x-axis
• ySemiAxis number semi (minor) axis of the ellipse along the y-axis

• options Object Optional parameters (optional, default {})

  • options.angle number angle of rotation in decimal degrees, positive clockwise (optional, default 0)
  • options.pivot Coord point around which any rotation will be performed (optional, default center)
  • options.steps number number of steps (optional, default 64)
  • options.units string unit of measurement for axes (optional, default 'kilometers')
  • options.properties Object properties (optional, default {})

Examples

var center = [-75, 40];
var xSemiAxis = 5;
var ySemiAxis = 2;
var ellipse = turf.ellipse(center, xSemiAxis, ySemiAxis);

//addToMap
var addToMap = [turf.point(center), ellipse]

Returns Feature<Polygon> ellipse polygon
