Karachi is the 2nd-largest city in the world by population within city limits and the 7th largest urban agglomeration in the world. Founded in the early 19th century, it is currently the a center of banking, industry and economic activity. Aside from being home to two international seaports, it is also home to textiles, shipping, automotive, entertainment, the arts, fashion, advertising, publishing,software development and medical research industries. Architecture in the city varies from 19th century colonial architecture to 21st century skyscrapers. Geographically, Karachi is very flat and spread out. The southern part of the city is a mix between mangrove creeks and beaches. The northern part of the city is mostly built atop a once desolate desert. Aside from the mangrove creeks and small islands, Karachi has two rivers that flow through it. The Malir and Lyari rivers. I think this map could be really interesting. Relatively flat with distinct features which could be a lot of fun to play with. Below are some photographs from Karachi.
