Cesium is a JavaScript geospatial visualization library and 3D globe engine designed to render world-scale environments and precision spatial data. It functions as a web-based mapping tool that displays hardware-accelerated 3D globes and 2D maps directly in a browser without requiring external plugins. The project operates as a 3D tiles renderer, utilizing the 3D Tiles open standard to stream and display large-scale geospatial datasets. It enables the visualization and analysis of high-accuracy spatial information across global environments. The library covers a broad range of capabilities,

Gridviz is a JavaScript library for visualizing gridded data (or any tabular dataset with x/y coordinates for that matter) in the browser using a large variety of cartographic styles and techniques. Unlike traditional raster-based web mapping tools, Gridviz renders everything client-side, on the…

The WRLD JavaScript API allows you to easily embed beautiful 3D maps into any web page for any modern, WebGL supporting browser. For an example of our 3D maps in action, see these examples.

WebGL map rendering engine for creative cartography

A library for building rich, web-based geospatial 2D & 3D data platforms.

Globe.GL

This module uses spherical GeoJSON to represent geographic features in JavaScript. D3 supports a wide variety of common and unusual map projections. And because D3 uses spherical geometry to represent data, you can apply any aspect to any projection by rotating geometry.

maptalks.js is a JavaScript map rendering library and web map interaction framework used to render interactive 2D and 3D geographic data on a web canvas. It functions as a 3D geospatial engine supporting 3DTiles and GLTF formats, a GeoJSON visualization tool, and a spatial analysis library. The project distinguishes itself through high-performance rendering and dynamic geospatial animation, including the ability to simulate traffic flow and execute smooth visual transitions for map elements. It provides comprehensive tools for interactive geometry editing, allowing users to draw and modify ve

Maplibre GL JS is a WebGL map rendering engine and vector tile map library used to create interactive web maps. It serves as a web-based GIS visualization tool and an interactive map interface framework for rendering geographic data and vector tiles on web pages. The library provides capabilities for 3D terrain rendering and the integration of custom 3D content. It supports complex geospatial data visualization through the use of heatmaps, clusters, and 3D extrusions, while allowing for custom map styling and environmental effect customization. The system covers a broad range of functional a
