It’s 5 in the morning,and I haven’t sleep yet … I mess a lot with Riau administrative boundary … it’s huge nodes after all … more than 10k nodes …

My big plan is – err was – to jump into admin_level 5 directly and add all 12 regencies/cities within Riau province [admin_level 4].

but … it’s not simple as my initial taught, whilst the boundary of riau and neighboring province is created from 3 sources and they all m:

• NE (Natural Earth) 10m –> this is so low res –> some how remind me with ESRI admin00 shp
• Bakosurtanal file (I think), from INIGIS website ( I got files like these prior 2014)
• new, revised 2014 boundaries [known as BPS 2010, because they embed BPS 2010 reference numbering scheme] , taken from PEMILU API, this is so far the newer one and the “most official” one …. aren’t them? lol

And … I’m too afraid messing around with previously old - sacred - relation / boundary created by OSM guru here … :lol:

I know I’m messing around here, and if you mad, you’ll find me in my campus, reviewing my student internship, gosh, there are 15 of them this 8’am, presenting…

[out:xml][timeout:25][bbox:{{bbox}}]; ( node["boundary"="administrative"]; way["boundary"="administrative"]; relation["boundary"="administrative"]; ); (._;>;); out meta;

^ my cheat sheet
