Introduction to geometry analysis

What is geometry analysis?

Geometry analysis is the process of using a client-side API to perform one or more operations on a point, polyline, or polygon to solve a geometric problem. You can use geometry operations to determine the spatial relationship between geometries, perform calculations such as creating a buffer, measure distance and area, and project geometries. The operation you use depends on the type of problem you are trying to solve.

Types of geometry operations

Geometry operations are grouped based on the type of calculation they perform and value returned.

Category	Description	Operations	Result	Example
Spatial relationship	Determine the relationship between geometries.	contains, disjoint, intersects, overlaps, touches, within	boolean	Determine the intersection of two geometries with intersects.
Geometric calculation	Calculate and create new geometries from an existing geometries.	boundary, buffer, clip, convexHull, cut, densify, difference, extent, generalize, intersect, nearestCoordinate, nearestVertex, offset, relate, reshape, simplify, trim, union	geometry	Buffer a line at 10 meters with buffer.
Length and area	Measure length, area, or distance.	area, distance, length	number	Calculate the geodesic length of a line with length.
Projection	Project to a new spatial reference.	project	geometry	Project a geometry to a new spatial reference with project.
