The Data Shark app is a proving ground for viewing real-time, near real-time, or static Big Ocean database sets in Augmented Reality AR. We can turn any dataset that includes latitude and longitude points into an Augmented Reality (AR) experience. This represents incredibly interactive opportunities for previously flat and non-interactive Big Ocean data. We can turn almost any data set that includes location info. (latitude/longitude) into an Augmented Reality interaction. Future possibilities include: - Ocean acidification - Jellyfish blooms - Shark tracking - General Fish movement patterns - Tide/Wave patterns THE FUTURE OF OCEAN DATA We strongly believe that Augmented Reality views represent the next evolution of viewing and interacting with ocean data in real time. Right in front of you. Right on your device's screen. The possibilities are truly incredible! We hope you enjoy our app!
