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
Merge multiple GeoJSON files into one FeatureCollection.
Cesium is a JavaScript library designed for rendering high-precision 3D globes and 2D maps within web browsers. It functions as a visualization engine that leverages hardware-accelerated graphics to display complex geographic data, terrain, and imagery. The library distinguishes itself through a modular architecture that supports the streaming of massive geographic datasets. By employing tiled data delivery and hierarchical level-of-detail optimization, it maintains performance while navigating large-scale environments. It also includes a time-dynamic state management system, which synchroniz
Add a unique id to features in a GeoJSON FeatureCollection with streaming.
de9im is a Javascript library that provides spatial predicate functions defined by the [Dimensionally Extended Nine-Intersection Model (DE-9IM)][de9im-wiki] and works with [GeoJSON][geojson-site] objects. It can test if two geometries have one of the following relationships: contains, coveredby,…
