Offline Turn-By-Turn Navigation Tools

OsmAnd is a mobile navigation application and vector map viewer that uses OpenStreetMap data to provide offline map access, turn-by-turn routing, and geospatial tools. It functions as a mobile routing engine and a GPX track recorder, allowing users to navigate and record movement without an active internet connection. The project integrates a mobile interface for contributing to the OpenStreetMap project, enabling users to report map errors and add new points of interest directly from their devices. It also includes a system for visualizing satellite imagery and custom tile overlays on top of

Organic Maps is a mobile application designed for offline mapping, navigation, and outdoor activity planning. It functions as a privacy-focused client for OpenStreetMap data, enabling users to explore locations, search for points of interest, and receive turn-by-turn directions entirely without an internet connection. The project distinguishes itself through a strict zero-telemetry privacy model that excludes trackers, data collection, and mandatory account requirements. By utilizing a native core engine and local-first data storage, it ensures that all user activity, location history, and pe

A copylefted libre software car-navigation system with its own routing engine.

X-Track is a firmware project for an embedded bicycle computer that combines GPS-based speed and ride metrics with offline map navigation. It functions as a GPS bicycle speedometer, displaying speed, distance, altitude, and other ride data on a handlebar-mounted screen, while also serving as an offline map viewer that renders locally stored map tiles without an internet connection. The project distinguishes itself by including a firmware emulator that runs the embedded code on a PC, enabling development and testing without physical hardware. It also provides GPS-based clock calibration to aut

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

GraphHopper is a Java routing library and OpenStreetMap routing engine used to calculate optimal paths and driving directions. It provides a map matching engine for aligning GPS coordinate traces to road networks, a GTFS transit router for multi-modal travel, and a spatial analysis utility for isochrone generation. The project supports the creation of custom vehicle profiles and weighting logic to influence path calculations. It implements contraction hierarchies to accelerate pathfinding by reducing the search space between coordinates. The engine covers a broad range of geospatial capabili

osrm-backend is a high-performance routing engine and backend service designed to calculate shortest paths and travel distances using OpenStreetMap data. It functions as a graph-based pathfinding server and map data processing tool that converts raw map data into specialized formats optimized for high-speed routing calculations. The system provides specialized route calculation for different transport modes, allowing for the definition of custom routing profiles with specific speed limits and travel constraints. It enables high-performance route planning and travel time estimation across larg

This is a Ruby toolkit for converting addresses to geographic coordinates and performing reverse geocoding via multiple external API providers. It provides a library for integrating location services into Ruby applications, including an IP geolocation tool to translate IP addresses into coordinates, city names, and country data. The project includes a command line interface for bulk geocoding of database records with integrated rate limiting and a geospatial query engine for calculating distances and performing radius or bounding box searches. It also features a mocking framework that provide

Project Nomad is a self-hosted survival suite and containerized offline operating environment. It provides a collection of essential tools, including a local retrieval-augmented generation system, an offline mapping server, and a local knowledge base for large language models, all designed to operate on air-gapped hardware. The system prioritizes total offline isolation to ensure telemetry-free operation. It enables private data analysis and semantic document querying through local-first vector storage and offline model execution, keeping all data on internal hardware without requiring intern

This project is a Python client library for interacting with Google Maps web services to retrieve geospatial, routing, and place data. It provides a programmatic interface for developers to access geocoding, elevation, time zone, and point-of-interest services. The library implements automatic exponential backoff and request retries to handle intermittent server errors and rate limit exceedances. It manages communication through credential-based authentication and session-based connection pooling to reduce latency across repeated API calls. The capability surface covers bidirectional geocodi

PMTiles is a cloud-native geospatial data format and a set of tools for creating cloud-optimized map tile archives. It organizes map tile pyramids into a single-file archive, allowing map data to be stored and retrieved from remote buckets without a dedicated backend database. The project provides a map tile format converter to transform various data sources into this unified archive and a map tile server proxy that serves these archives to display systems using standard protocols. It enables the use of HTTP byte-range requests and metadata-driven indexing to retrieve specific tiles without d

Mapscii is a terminal-based geographic interface and vector map renderer. It allows users to view and explore geographic map data and points of interest directly within an xterm-compatible console using ASCII and Braille characters. The project functions as a vector tile map client capable of fetching and styling geographic layers from public or private sources. It also serves as an MBTiles map viewer, enabling the exploration of geographic data stored in local files for offline use. The tool provides keyboard-driven navigation for zooming and panning across coordinates, along with the abili
