# Colombo: Skylines by Nimesha Periyapperuma and Yudhanjaya Wijeratne This repository contains Team Watchdog's simulation of the city of Colombo. This is an accurate topographical representation of Colombo, built with detailed land use and zoning based on official city development plans and data centered around 2020; over a million virtual citizens, simulating population dynamics that reflect large-scale, real-world demographics and human movement; public transport based on actual route data; and curated visual assets to better match Colombo's unique architectural style.  We've also set up a [wiki to explain how we did it and how you can get this running on your own machine](https://github.com/team-watchdog/colombo-skylines/wiki). > [!NOTE] > Tested on Windows 11 and Pop OS 22.04 LTS. To make it easier to install, we've uploaded the full folder structure, including mod configs. This project is built with the use of publicly available data from - Colombo Municipal Council - Sri Lanka Road Development Authority - Sri Lanka Urban Development Authority - Sri Lanka Department of Census and Statistics - University of Moratuwa's Department of Transport and Policy Planning - META's Data for Good projects, especially their population mapping work with the Center for International Earth Science Information Network (CIESIN) at the Columbia Climate School - UN-Habitat - The ComTRANS reports and its associated studies and surveys - OpenStreetMap - ESA's Sentinel-2 program, from which we've gotten a lot of satellite imagery: see [https://github.com/team-watchdog/satellite2024](https://github.com/team-watchdog/satellite2024) - Google Maps and Routemaster.lk for bus and train routes ## Table of Contents 1.

[Contact](#contact) ## Introduction In early 2024, we started working on something to help the general public better understand the city of Colombo and the impacts of various urban design interventions. Our goal was to create a more accessible and visual tool for citizens to comprehend urban problems and judge the impact of different decisions. This project was inspired by our previous work at Watchdog, where we spend months of research and ultimately [wrote a monumental 13,000+ word collection on explaining Sri Lankan transport](https://watchdog.team/article/too-slow-too-furious). Ultimately, what we realized was that there had to be some visual way to bridge the gap between professional expertise (often confined to academic papers and reports) and public understanding. Our virtual city of Colombo serves as a crude "Digital Twin," offering a platform to: 1. Visualize and understand current urban design issues 2. Test and communicate potential infrastructure changes 3. Explore the impact of policy decisions on traffic and population distribution 4. Educate students and the public about urban planning concepts Potential applications include: 1. Simulating changes in roads, transport routes 2. Exploring effects of changes in private transport policies 3. Visualizing impact of new infrastructure like monorails or wider pavements 4. Assessing effects of introducing more green spaces or parking areas  While not a completely accurate simulation, this "toy universe model" provides a useful tool for visualizing and communicating urban development
