Method Details

buffer(geometry, distance, unit, unionResults){Polygon|Polygon[]}

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:
geometry Geometry | Geometry[]

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.

distance Number | Number[]

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 String | Number

Measurement 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.

Possible Values: meters | feet | kilometers | miles | nautical-miles | yards

unionResults Boolean
optional

Determines whether the output geometries should be unioned into a single polygon.

Default Value: false

Returns:
TypeDescription
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.

convexHull(geometry, merge){Geometry|Geometry[]}

Calculates the convex hull of the input geometry. A convex hull is the smallest convex polygon that encloses a group of Objects, such as points. The input geometry can be a point, multipoint, polyline or polygon. The hull is typically a polygon but can also be a polyline or point in degenerate cases.

BooleanReturns true if geometry1 crosses geometry2.
See also:

cut(geometry, cutter){Geometry[]}

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.

Parameters:
geometry Geometry

The geometry to be cut.

See also:

geodesicArea(geometry, unit){Number}

Calculates the area of the input geometry. As opposed to planarArea(), geodesicArea takes into account the curvature of the earth when performing this calculation. 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.

This method only works with WGS84 (wkid: 4326) and Web Mercator spatial references.

Parameters:
geometry Polygon

The input polygon.

See also:

geodesicBuffer(geometry, distance, unit, unionResults){Polygon|Polygon[]}

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:
geometry Geometry | Geometry[]

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.

distance Number | Number[]

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 String | Number

Measurement 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.

Possible Values: meters | feet | kilometers | miles | nautical-miles | yards

unionResults Boolean
optional

Determines whether the output geometries should be unioned into a single polygon.

Default Value: false

Returns:
TypeDescription
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.

maxSegmentLengthUnit String | Number

Returns:
TypeDescription
GeometryReturns the densified geometry.

Example:
// lineGeom is a line geometry
var densifiedGeom = geometryEngine.geodesicDensify(lineGeom, 10000);

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

Parameters:
geometry Geometry | Geometry[]

The offset distance for the Geometries. 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.

relation String

The Dimensionally Extended 9 Intersection Model (DE-9IM) matrix relation (encoded as a string) to test against the relationship of the two geometries. This string contains the test result of each intersection represented in the DE-9IM matrix. Each result is one character of the string and may be represented as either a number (maximum dimension returned: 0,1,2), a Boolean value (T 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.

See this article and this ArcGIS help page for more information about the DE-9IM model and how string codes are constructed.
