How to Download Surveillance in Bengaluru Data
Even though I have blogged about it in the original post about this, I keep getting asked this question, hence a dedicated blog post.
Everything we map goes directly to OpenStreetMap. The data on OpenStreetMap is available for free under ODBL. The easiest way to download Surveillance in Bengaluru data is from Overpass Turbo. I have written some queries below that you can use on Overpass Turbo to get the data. I also have a demo video for you.
What I consider Bengaluru for this project

For any area

If you have built something using this data or planning to, let me know. I am curious.
