2. Two communities in Quito were compared both started in 1980, in the same section of Quito: Lucha de los Pobres: originally an informal squatter settlement, Solanda: a formal government/international development agency project. scale 1:--- 0 15 30 50 200 m 100 N Solanda Lucha de los Pobres Main Street

(Battery life is critical because of short effective flight times)
