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 clie
.Net library for GeoJSON types & corresponding Json.Net (de)serializers
GraphHopper is a Java routing library and OpenStreetMap routing engine used to calculate optimal paths and driving directions. It provides a map matching engine for aligning GPS coordinate traces to road networks, a GTFS transit router for multi-modal travel, and a spatial analysis utility for isochrone generation. The project supports the creation of custom vehicle profiles and weighting logic to influence path calculations. It implements contraction hierarchies to accelerate pathfinding by reducing the search space between coordinates. The engine covers a broad range of geospatial capabili
