Thinking Machines, a Philippine data science services company, did an
analysis of where in the Philippines buildings are still missing by
comparing OSM data with the Facebook's population dataset:


The provinces that are very complete are due to mapping in the wake of
disasters (like Typhoon Haiyan in 2013 and Typhoon Mangkhut in 2018) like

of NOAH, a government disaster analysis institution, like Cavite, Batangas,
