Turf.js

Turf.js is a JavaScript library for performing geospatial operations. It provides a variety of functions for analyzing and manipulating geographic data, including functions for finding the distance between two points, generating a random point within a polygon, and creating a buffer around a feature.

Turf.js is designed to be used in the browser or on the server with Node.js. It can be used in a variety of applications, including web mapping applications, geographic information systems (GIS), and geospatial analysis tools.

Some examples of the types of operations that Turf.js can perform include:

• Measuring the distance between two points
• Calculating the area of a polygon
• Determining the intersection of two polygons
• Generating a random point within a polygon
• Creating a buffer around a point, line, or polygon
• Performing spatial joins (e.g., finding all points within a polygon)

Turf.js is built on top of the popular open-source library, JSTS (JavaScript Topology Suite), and uses the GeoJSON data format for representing geographic features. It is easy to use and can be easily integrated into web applications using a simple API.
