This project is a comprehensive geographic location dataset and reference library providing standardized data for countries, states, and cities. It serves as a source of truth for regional hierarchies, ISO codes, coordinates, and timezone information, available as both a relational SQL database and a document-based JSON library. The project includes a custom dataset export tool that functions as a filtering engine. This allows for the generation of tailored geographic files in JSON, CSV, and GeoJSON formats by selecting only the specific regions or fields required. The dataset covers global

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

Flutter Deer is a Flutter practice project that demonstrates realistic application patterns across Android and iOS. It showcases how to structure a Flutter app with modular routing, reactive state management using Provider, and a centralized network layer built with Dio for structured API calls and error handling. The project also includes integration and accessibility testing that simulates real user interactions to verify UI behavior and screen-reader compatibility. The project differentiates itself by providing a comprehensive showcase of custom UI components and interactions, including ca

This repository provides a curated collection of weekly datasets designed for data visualization practice, data science education, and statistical analysis. It serves as a central source for cleaned and structured real-world data, allowing practitioners to focus on analysis and visualization without the need to scrape or clean raw files. The project facilitates a community learning workflow where users can explore a wide variety of topics, ranging from global health spending and energy datasets to maritime logs and baby name popularity. Participants are encouraged to share their resulting vis

A/B Street is an open-source traffic simulation and urban planning tool that models how cars, bikes, and pedestrians move through real-world street networks. It imports data from OpenStreetMap to build detailed, lane-level road models, then runs discrete-event simulations to analyze travel times, delays, and congestion patterns across different infrastructure scenarios. The project provides an interactive map editor for modifying road geometry, lane configurations, traffic signals, and access restrictions, with full undo/redo support. Users can design low-traffic neighborhoods by placing moda

This project is an administrative GIS toolset that provides a comprehensive dataset of China's administrative divisions, including provinces, cities, districts, and townships. It functions as a coordinate system transformer and a boundary converter for transforming geographic data into standard formats. The toolset distinguishes itself through the ability to convert administrative boundary data between CSV, GeoJSON, Shapefiles, and SQL. It includes specialized utilities for coordinate system transformation between GCJ-02, BD-09, WGS-84, and CGCS2000 standards to ensure accuracy across differe

OpenSC2K هو محرك بناء مدن JavaScript مفتوح المصدر مصمم كإعادة إنشاء لـ SimCity 2000. يعمل كمحاكاة تعتمد على الويب تستخدم إطار عمل Phaser 3 لتنفيذ حلقات اللعبة وإدارة الكيانات. يستخدم المشروع عرض WebGL و Canvas لتصور البيئات الحضرية واسعة النطاق. يتضمن نظام كاميرا يعتمد على الإحداثيات يتيح التحريك والتكبير عبر عالم اللعبة المعاد بناؤه. يدمج المحرك خط أنابيب بيانات لتحليل ملفات المدن القديمة وأصول الرسومات، مما يسمح له بإعادة بناء وعرض التخطيطات الحضرية داخل متصفح ويب حديث.

SUMO is a microscopic traffic simulator and road network generator designed to model the detailed movement of individual vehicles, pedestrians, and public transport. It serves as a multimodal transport simulator and an autonomous vehicle simulator, enabling the analysis of interactions between different transport modes and the testing of automated driving behaviors. The project distinguishes itself through its ability to couple simulations with external controllers and network simulators to model vehicle communication and autonomous control transitions. It supports the creation of simulation-

SUMO is a microscopic traffic simulation suite designed to model the movement of individual vehicles and pedestrians across large-scale urban road networks. It functions as a multimodal transport simulator that integrates cars, pedestrians, bicycles, railways, and waterways within a single environment, supported by tools for road network generation and traffic demand modeling. The project distinguishes itself through specialized toolsets for environmental impact analysis, which calculate vehicle emissions and energy consumption for electric and hybrid fleets. It provides comprehensive capabil
