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

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

Mapbox GL JS هو محرك عرض خرائط WebGL وإطار عمل خرائط ويب تفاعلي يُستخدم لعرض البلاطات المتجهة (vector tiles)، والصور النقطية، والتضاريس ثلاثية الأبعاد في المتصفح. يعمل كمكتبة خرائط للبلاطات المتجهة وأداة لتصور البيانات الجغرافية المكانية، ويستخدم تظليلات (shaders) مسرعة بواسطة GPU لتحويل البيانات الجغرافية المكانية إلى خرائط تفاعلية. يتميز المشروع من خلال دمج طبقات WebGL مخصصة مباشرة في خط أنابيب العرض واستخدام تعبيرات تعتمد على البيانات لربط خصائص المعالم بالسمات المرئية. وهو يدعم تحميل البيانات المتخصصة عبر PMTiles ويوفر إدارة خرائط دون اتصال بالإنترنت من خلال الحزم وقواعد البيانات المحلية. يغطي المحرك مجموعة واسعة من الإمكانيات، بما في ذلك عرض التضاريس والمباني ثلاثية الأبعاد مع الإضاءة والظلال، وتتبع موقع المستخدم في الوقت الفعلي، ورسوم متحركة برمجية للكاميرا. كما يوفر استعلاماً مكانياً لاسترجاع المعالم، والتصفية الديناميكية، ونظام واجهة مستخدم لعلامات HTML والنوافذ المنبثقة للمعلومات. تتضمن المكتبة تكوينات بناء لإنشاء حزم تلبي قيود سياسة أمان المحتوى (Content Security Policy) لعمال الويب (web workers).

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

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

Omim is a suite of compilers and orchestrators designed to transform raw geographic and transit data into renderable offline map binaries. It provides a map generator for converting OpenStreetMap data into optimized binary files, a styling compiler for visual feature representation, and a rendering engine for visualizing geographic data from local storage without an internet connection. The project includes a map tile build orchestrator that sequences generation and optimizes resource utilization based on historical statistics. It also features a dedicated transit data processor that transfor

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
