Hi, my company offers exactly this. Data collection, stitching, anonymization, and so on. I have been doing this for over 15 years. Https://www.mosaic51.com

Get in touch, let's talk.

Stay away from the home grown solutions, they are not robust, reliable, or scalable. You'll waste a ton of time and money on them with bad results.

Our systems have been used all over the world to map entire countries with no hardware failures.

Happy to talk!
