#GETTING A PERFECT CENTER POINT MEASURE FULL#

This is a geodesic measurement, which calculates distances on an ellipsoid. Returns the geodetic buffer at a specified distance around the input geometry. Returns a polygon representing a 1/2-mile buffer around the input geometryīufferGeodetic BufferGeodetic(inputGeometry, distance, unit?) -> Polygon Possible values: feet | kilometers | miles | nautical-miles | meters | yards In other profiles, like field calculation, the default is based on the spatial reference of the data. For the visualization, labeling, and popup profiles, the default unit is the map's spatial reference.

unit ( Optional): Text | Number - Measurement unit of the buffer distance.

distance: Number - The distance to buffer from the geometry.

inputGeometry: Geometry | Feature - The geometry to buffer.

This is a planar measurement using Cartesian mathematics.

unit ( Optional): Text | Number - Measurement unit of the return value.

polygon: Polygon | Feature | Array - The Polygon or Feature for which to calculate the geodetic area.

Other profiles, such as popup, provide the full resolution geometry. $feature) as input to any geometry function in these contexts will return different results at each scale level. Therefore, using a feature's geometry (i.e. Support is limited to geometries with a Web Mercator (wkid 3857) or a WGS 84 (wkid 4326) spatial reference.įeature geometries in the visualization and labeling profiles are generalized according to the view's scale resolution to improve drawing performance. This is more reliable measurement of area than Area() because it takes into account the Earth's curvature. Returns the geodetic area of the input geometry or Feature in the given units. Returns the angle from a Point to a Feature, in degreesĪreaGeodetic AreaGeodetic(polygon, unit?) -> Number pointB: Point | Feature - The second Point or Feature used to calculate the angle.pointA: Point | Feature - The first Point or Feature used to calculate the angle.If the points are identical, then an angle of 0 degrees is returned. Point features can be used instead of any or both Point geometries. Only the x-y plane is considered for the measurement. For example, an angle of 90 degrees points due north. The angle is measured in a counter-clockwise direction relative to east.

Returns the arithmetic angle of a line between two points in degrees (0 - 360). Angle(pointA, pointB, pointC) -> Number.Please note that if your input has more than one geometry, they must have the same spatial reference. The following functions allow you to create and evaluate geometry objects.
