### Method Details

Creates planar (or Euclidean) buffer polygons at a specified distance around the input geometries.

The GeometryEngine has two methods for buffering geometries client-side: buffer and geodesicBuffer. Use caution when deciding which method to use. As a general rule, use geodesicBuffer if the input geometries have a spatial reference of either WGS84 (wkid: 4326) or Web Mercator. Only use buffer (this method) when attempting to buffer geometries with a projected coordinate system other than Web Mercator. If you need to buffer geometries with a geographic coordinate system other than WGS84 (wkid: 4326), use GeometryService.buffer().

Parameters:The buffer input geometry. The

`geometry`

and`distance`

parameters must be specified as either both arrays or both non-arrays. Never specify one as an array and the other a non-array.The specified distance(s) for buffering. The

`geometry`

and`distance`

parameters must be specified as either both arrays or both non-arrays. Never specify one as an array and the other a non-array.

When using an array of geometries as input, the length of the geometry array does not have to equal the length of the`distance`

array. For example, if you pass an array of four geometries:`[g1, g2, g3, g4]`

and an array with one distance:`[d1]`

, all four geometries will be buffered by the single distance value. If instead you use an array of three distances:`[d1, d2, d3]`

,`g1`

will be buffered by`d1`

,`g2`

by`d2`

, and`g3`

and`g4`

will both be buffered by`d3`

. The value of the geometry array will be matched one to one with those in the distance array until the final value of the distance array is reached, in which case that value will be applied to the remaining geometries.unit LinearUnits|NumberMeasurement unit of the distance(s). Defaults to the units of the input geometries. Use one of the possible values listed below or any of the numeric codes for linear units.

unionResults BooleanoptionalDefault Value: falseDetermines whether the output geometries should be unioned into a single polygon.

Returns:Type Description Polygon | Polygon[] The resulting buffer(s). The result will be an array if an array of geometries is used as input. It will be a single polygon if a single geometry is input into the function. - See also:

Example:`// Buffer point by 1000 feet var ptBuff = geometryEngine.buffer(point, 1000, "feet");`

- clip(geometry, envelope){Geometry}
Calculates the clipped geometry from a target geometry by an envelope.

Split the input Polyline or Polygon where it crosses a cutting Polyline. For Polylines, all left cuts are grouped together in the first Geometry. Right cuts and coincident cuts are grouped in the second Geometry and each undefined cut, along with any uncut parts, are output as separate Polylines. For Polygons, all left cuts are grouped in the first Polygon, all right cuts are grouped in the second Polygon, and each undefined cut, along with any left-over parts after cutting, are output as a separate Polygon. If no cuts are returned then the array will be empty. An undefined cut will only be produced if a left cut or right cut was produced and there was a part left over after cutting, or a cut is bounded to the left and right of the cutter.

or, if`distanceUnit`

Therefore, when using input geometries with a spatial reference of either WGS84 (wkid: 4326) or Web Mercator, it is best practice to calculate areas using geodesicArea(). If the input geometries have a projected coordinate system other than Web Mercator, use planarArea() instead.

Returns:Type Description Number Area of the input geometry. - See also:

Creates geodesic buffer polygons at a specified distance around the input geometries. When calculating distances, this method takes the curvature of the earth into account, which provides highly accurate results when dealing with very large geometries and/or geometries that spatially vary on a global scale where one projected coordinate system could not accurately plot coordinates and measure distances for all the geometries.

This method only works with WGS84 (wkid: 4326) and Web Mercator spatial references. In general, if your input geometries are assigned one of those two spatial references, you should always use geodesicBuffer() to obtain the most accurate results for those geometries. If needing to buffer points assigned a projected coordinate system other than Web Mercator, use buffer() instead. If the input geometries have a geographic coordinate system other than WGS84 (wkid: 4326), use GeometryService.buffer().

Parameters:The buffer input geometry. The

`geometry`

and`distance`

parameters must be specified as either both arrays or both non-arrays. Never specify one as an array and the other a non-array.The specified distance(s) for buffering. The

`geometry`

and`distance`

parameters must be specified as either both arrays or both non-arrays. Never specify one as an array and the other a non-array.

When using an array of geometries as input, the length of the geometry array does not have to equal the length of the`distance`

array. For example, if you pass an array of four geometries:`[g1, g2, g3, g4]`

and an array with one distance:`[d1]`

, all four geometries will be buffered by the single distance value. If instead you use an array of three distances:`[d1, d2, d3]`

,`g1`

will be buffered by`d1`

,`g2`

by`d2`

, and`g3`

and`g4`

will both be buffered by`d3`

. The value of the geometry array will be matched one to one with those in the distance array until the final value of the distance array is reached, in which case that value will be applied to the remaining geometries.unit LinearUnits|NumberMeasurement unit of the distance(s).

- geodesicLength(geometry, unit){Number}
Calculates the length of the input geometry. As opposed to planarLength(), geodesicLength() takes into account the curvature of the earth when performing this calculation.

The offset operation creates a geometry that is a constant planar distance from an input polyline or polygon. It is similar to buffering, but produces a one-sided result.

Parameters:The geometries to offset.

offsetDistance NumberThe planar distance to offset from the input geometry. If offsetDistance > 0, then the offset geometry is constructed to the right of the oriented input geometry, if offsetDistance = 0, then there is no change in the geometries, otherwise it is constructed to the left. For a simple polygon, the orientation of outer rings is clockwise and for inner rings it is counter clockwise. So the "right side" of a simple polygon is always its inside.

joinType StringThe join type.

relation StringThe Dimensionally Extended 9 Intersection Model (DE-9IM) matrix relation (encoded as a string) to test against the relationship of the two geometries.

Each result is one character of the string and may be represented as either a number (maximum dimension returned:

`0`

,`1`

,`2`

or`F`

), or a mask character (for ignoring results: '*').

Example: Each of the following DE-9IM string codes are valid for testing whether a polygon geometry completely contains a line geometry:`TTTFFTFFT`

(Boolean), 'T******FF*' (ignore irrelevant intersections), or '102FF*FF*' (dimension form). Each returns the same result.
