gmaps is a library that provides a wrapper for the Google Maps API, serving as a geospatial data toolkit and interactive map renderer. It simplifies the integration of interactive maps into web applications by managing the embedding of map views and the lifecycle of markers. The project distinguishes itself through a specialized set of utilities for geocoding, which converts physical addresses to geographic coordinates and vice versa. It also includes a static map generator for creating non-interactive map images for lightweight environments. The capability surface covers geographic data vis

The NASA WorldWind Javascript SDK (WebWW) includes the library and examples for creating geo-browser web applications and for embedding a 3D globe in HTML5 web pages.

Bertin.js is a JavaScript library for visualizing geospatial data and make thematic maps for the web.

This project is a GIS component library and a React wrapper for the Leaflet mapping library. It acts as a bridge between the imperative Leaflet API and the declarative state management of React, allowing for the creation of interactive geographic maps and spatial data visualizations. The library uses a component-based architecture to render maps with markers and layers. It synchronizes the React virtual DOM with the map's internal layer registry to maintain a consistent geographic state, mapping component lifecycles to the addition and removal of map layers. The tool provides capabilities fo

Add time dimension capabilities on a Leaflet map.

Pixel based heatmap with html5 canvas.

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

deck.gl is a GPU-accelerated geospatial engine and WebGL2 data visualization framework. It functions as a high-performance spatial visualizer and map overlay library designed to render large-scale spatial and temporal datasets. The system specializes in mapping data arrays into visual layers for complex geographic representations. It provides the capability to create interactive visual overlays and cartographic projections that align with various third-party map providers. The framework supports large-scale data visualization, interactive spatial analysis, and the development of custom high-

react-map-gl is a React component library for embedding and controlling Mapbox GL JS interactive maps. It serves as a high-level bridge that maps the imperative methods of the Mapbox GL JS engine to a declarative component state. The project allows for the development of custom map interfaces and geospatial data visualizations. It enables the creation of location-based web applications by providing a reusable UI element for rendering vector tiles and spatial information.
