I am looking for city and neighboorhood level (and other administrative divisions) data for as many countries in SE Asia as possible. It must be free to access and use. Trusted/official data is preferred (i.e. local, municipal, national governments, universities).
Specific countries and the administrative levels include:
Cambodia: (Section (ខណ្ឌ khan), Quarter (សង្កាត់ sangkat), Commune(ឃុំ khum), Municipality (ក្រុង krong), Village (ភូមិ phum).
Indonesia: City (Kota), Distrik (district), Desa (villages, Kelurahan (urban communities), Rukun Tetangga (neighborhoods) and Rukun Warga (???).
Malaysia: District (Malay: Daerah; Jajahan in Kelantan and Bahagian in Sabah and Sarawak), Muhkim.
Taiwan: Neighborhoods within villages, towns and cities.
Vietnam: Ward, (Phường), District-level town/Town (Thị xã), Ward (Phường) Commune (Xã), Commune-level town/Township (Thị trấn)
I have grabbed what I can from Open Street Map, Geonames, and http://www.diva-gis.org/ but I'm looking for what is listed above. I have taken suggestions Stack Exchange questions (http://freegisdata.rtwilson.com/) I have also looked at https://opendatainception.io/ (awesome website, check it out).
I am looking for vector data only (polygons, points, lines). Thoughts? Ideas?
