Latent Land

Tide is a unique temporal environmental phenomenon, caused by combined effects of gravitational forces exerted by the Moon and the Sun, and the rotation of the Earth. Its change varies on time scales. In River Thames, the time range of tidal changes is around 4h 17mins at the time, which is less than the minimum time scale that Google Earth can accurately describe its ebb and flow and the shifting bank line.

To refine extra dimensional digital representation geographically. I used a photogrammetry technology as my measuring device to orbit and to observe the overtime changes. Since the optical scanning performance of the measuring tool was disturbed by the flux reflection of the flowing river surface, this investigation had unexpectedly revealed an emerging land that thus auto-generated from the machine’s failure/mind.

Our landscape is being morphologically transformed by the entanglement of both environmental and technological factors in the era when technology is increasingly becoming our priority sense.
