Open-source alternatives to Tilelive Postgis

TileStrata provider for rendering tiles with mapnik.

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

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

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.

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,…

AngularJS directive to embed an interact with maps managed by Leaflet library

Sample heat map implementation in Javascript

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

Geometric.js is a JavaScript library for working with points, lines, polygons, and angles. It uses plain JavaScript arrays for geometry primitives, includes TypeScript declarations for editor autocomplete and type checking, and works in modern browsers and Node.js.

Libraries of geodesy functions implemented in JavaScript

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

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…

Geolib is a geospatial calculation library and point analysis tool. It provides a collection of utilities for computing distances, bearings, and areas between coordinates, as well as converting geographic measurements and coordinate formats. The library features a Well-Known Text geometry parser to convert WKT strings into coordinate structures for polygon analysis. It includes specialized tools for geofencing and point containment, enabling the determination of whether a coordinate falls within a defined polygon or a specified radius. The toolset covers broad capability areas including loca

A compact binary encoding for geographic data.

geotiff.js is a small library to parse TIFF files for visualization or analysis. It is written in pure JavaScript, and is usable in both the browser and node.js applications.
