That system of vector maps is in popular use atleast since the 1970s, so when Google maps started, they could just collect existing gis (geographic information systems) maps. I wasn’t born yet, but I expect that countries/companies started digitizing their old maps in the 1970s and 1980s and that paper prints after that were based on those digital versions. And countries without good maps to start from (too large/remote/administratively weak), probably started their digital mapping projects based on aerial photos. And when Papua New Guinea finally starts with a digital mapping project, they can start straight away from satellite photos :)
Indonesia Hospital is the name and it’s named that way because it was sponsored by the Indonesian people.

Construction of the hospital began in 2011 on 16,000 square meters of land donated by the government of Gaza.[3][1] The project cost IDR 126 billion and was funded by donations from Indonesian people and organizations such as the Indonesian Red Cross Society and Muhammadiyah, collected through the Indonesian humanitarian organization Medical Emergency Rescue Committee (MER-C).[4][5] Then-Indonesian Vice-president Jusuf Kalla inaugurated the hospital on 9 January 2016.[3]
