📍Думали ли Вы о Римской империи сегодня?
Империя охватывала большую территорию, но в те времена дорога занимала много времени. Например:
• Путь из Рима в Александрию зимой занимал в 4 раза больше времени
• Доставка вина из Помпей (250 км) в Рим составляла 55% его стоимости
• Решение о войне с Парфией зависело не от расстояния, а от цены провизии
🎓Стэнфордский университета запустил проект ORBIS — цифровую модель, которая показывает дороги и позволяет строить маршруты в Римской Империи с учетом времени (сезонов, погодных условий, расстояния), стоимости (налоги, фрахт кораблей, корм для животных), риски (пираты, штормы, горные перевалы).
Проект: https://orbis.stanford.edu/
В летнее время самый быстрый маршрут из Рима в Лондиниум пешком (30 км в день) занимал почти 27 дней, учитывая морские перемещения из Рима на юг современной Франции и дальше через Бискайский залив. Зимой 42 дня.
В некоторых случаях самым дешевым способом передвижения были ослы, особенно по горным тропам

🌍 The point where 60° north latitude meets 60° east longitude is in a remote forest of Russia—this rare intersection is called the "triple 60s" and has no nearby settlements or roads. ✨

🌍 The intersection of four whole-degree geographic coordinates (latitude and longitude) on land is extremely rare. One of the only land spots where this happens is near Lake Chad in central Africa. ✨

city-roads
city-roads is a browser-based mapping tool that draws every road in a selected city as a single, clean line map. After a user enters a city name, it retrieves the city’s road geometry from OpenStreetMap and renders the full street network in the browser, making it useful for exploring urban layouts, comparing city structures, and creating visually striking map graphics.

🌍 The intersection of 0° latitude and 0° longitude is called "Null Island." It's marked on maps but sits in the Gulf of Guinea, with only a weather buoy at this exact ocean spot. ✨
