Can Maps JavaScript API perform spatial calculations (like distance, area, or point-in-polygon)?

The Geometry Library in Maps JavaScript API will do basic spatial calculations, including:

• Area
• Distance
• Heading
• Length
• Point-on-Edge
• Point-in-Polygon

Geometry Library is not enabled by default, it is an optional supplemental library. To include Geometry Library, add &libraries=geometry to the bootstrap URL when you load Maps JavaScript API.

Need more functions than Geometry Library provides? Check out Turf. Turf is an open-source JavaScript library for performing spatial analysis. It'll work client-side in the browser or server-side in Node.js. Turf operates on GeoJSON data, making it a perfect complement to Data Layer.
