Turf
Turf is a JavaScript and TypeScript geospatial analysis library and toolkit used for performing spatial analysis and geometric operations on GeoJSON data. It functions as a modular spatial engine that allows for the generation, manipulation, and classification of geographic datasets within web and node environments.
The library provides a set of utility functions to programmatically create structured points, lines, and polygons. It enables the calculation of distances, areas, and geometric relationships between geographic coordinates, supporting both browser-based geospatial analysis and client-side spatial statistics.
Its capability surface covers GeoJSON data processing, geospatial analysis, and the calculation of spatial statistics to identify patterns and distributions across geographic areas. It also provides the derived coordinates and shapes required for interactive map visualization.
