If you're into #OSINT or #geolocation, something new is coming... I've long predicted the convergence of data science and OSINT. While I couldn't have seen the emergence of generative AI, I knew that audio analysis at scale was happening; I knew that video analysis at scale was coming. I wish I'd seen how this would impact geolocation. What I didn't see then I see now. And I've been working with GOΠZO to expand GVision into a full geolocation suite and while we have a long way to go, we've made substantial progress. Coming soon to a web browser near you, Geolocate.
