Open-source alternatives to Ui Leaflet

Add time dimension capabilities on a Leaflet map.

Blazing Fast JavaScript Raster Processing Engine

Draw tools for mapbox-gl-js

This project contains the TypeScript definitions for the Bing Maps V8 Web Control.

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

Pixel based heatmap with html5 canvas.

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.

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.

This is a collection of over two hundred code samples an growing for the Bing Maps V8 web control.

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

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

Data-driven web maps based on D3 🗺️

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 GeoJSONgeojson-site objects. It can test if two geometries have one of the following relationships: contains, coveredby,…

gcoord is a coordinate conversion library that transforms geographic coordinates between China's three major map coordinate systems: WGS-84, GCJ-02, and BD-09. It handles the offset corrections required by national encryption policies, converting GPS or API-derived coordinates to align with the projections used by Chinese map providers like Baidu, Gaode, and Google China. The library provides direct conversions between all three systems, including WGS-84 to GCJ-02, WGS-84 to BD-09, GCJ-02 to BD-09, and their reverse transformations. It processes individual coordinate pairs, batches of coordin

gdal3.js is a port of Gdal applications (gdaltranslate, ogr2ogr, gdalrasterize, gdalwarp, gdaltransform) to Webassembly. It allows you to convert raster and vector geospatial data to various formats and coordinate systems.

This is the leaflet plugin for GeoServer. Using this plugin user can have access to wms and wfs request easily.

A real-time vehicle fleet simulator that runs vehicles on actual road networks with A\* pathfinding, realistic motion physics, BPR traffic congestion, time-of-day patterns, geofencing, incident-based rerouting, session recording, and a custom browser-side map rendering engine — no map tile…

Openstreetmap static maps is a nodejs lib, CLI and server open source inspired on google static map service

SpatiaLite 5.1.1-rc0 and friends - sqlite 3.51.1, geos 3.14.1, proj 9.7.1, rttopo 1.1.0 - for node (sync API) and browser (async API).

Transform, query, and download geospatial data on the web.

This project is a geospatial data rendering engine and OpenStreetMap road network visualizer. It functions as a vector map visualization tool that imports geocoded area data and converts road layouts into visual layers for digital or physical output. The system enables the creation of generative map art and stylized images intended for physical production via pen-plotters or laser cutters. It allows for the manipulation of line widths and colors of city streets to produce custom visual representations of urban environments. The engine provides capabilities for urban road visualization, geogr
