Open-source alternatives to Geoblaze

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

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.

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.

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

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.

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,

Euclid.ts is a Typescript library for 2D geometry. It contains classes for elements like points, lines, circles, and polygons, intersection detection, as well as SVG and Canvas drawing tools. It was developed for Mathigon.org, an award-winning mathematics education project.
