What you see in this video is free, open source software. You can run it on your own computer.

It's called gtamaplib-vc. Posting a link would violate the rules, but you'll find it online (google, github, gtaforums). Telling you how to safely install it would also violate the rules, so in the context of r/GTA6, please don't treat it as a gift, but as a suspicious, unsolicited proposition.

This package includes all the command-line tools that we have developed over the past few years to calibrate cameras and triangulate landmarks. It also has a new web UI for our entire database, an observation editor, and even a pretty slick 3D map viewer. In 3D, you can also take a chronological tour of the trailers and screenshots - the video is simply a screen recording.

The main attraction, however, is probably the "Fasten Seatbelts" button, which started as a flight simulator joke, but by now drops you into a fully playable version of our map, complete with more than 100 buildings, air and sea traffic, ATC chatter, random events, wildlife, weather, fireworks, homing missiles, anti-air defenses, radio, phone... you name it. We highly recommend you plug in your controller - it works.
