If anyone who want to edit Indonesian maps, I recommend using BHUMI ATR/BPN aerial imagery data as source. You may see the links from my last 2 months of renewed editing career of OpenStreetMap.

The primary reason I use BHUMI is their data quality is crisper and detail than Bing/Esri data (but as crisp as OpenAerialMap data), more extensive (OAM has limited coverage; in Indonesian context, their coverage is tinier than a grain of rice) and as a work of Ministry of Agrarian and Spatial Planning (Kementerian Agraria & Tata Ruang/Badan Pertanahan Negara), based from open data and their BHUMI website does not mention the copyright, it is in public domain (art. 43 point B of 2014 Copyright law/UU No. 28 Tahun 2024).

(You may object the last one, as I judge it solely on their website’s statement and my limited understanding to Copyright Law. In their website, the term of use is only limited to general responsibility using BHUMI ATR/BPN data. If you consider their data as copyrighted, that means 2 months’ worth of cleanup. Not an easy task, I hope don’t let it happen!)

However, some of their data might be not up to date or broken, so please cross-check with less than detail Bing/Esri data and zooming in and out, because you could get detail out of it.

I have big wish about this: ATR/BPN keep making high-quality imagery, and Indonesian OAM contributors to do the same, not just waking up when they do a mapathon!
