Hidden Island





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 in timescales. In River Thames, the time range of tidal changes was approximately 4h 17mins during my observation, which is less than the minimum time scale that orbiting satellites can accurately describe its ebb and flow and the shifting bank line.






To refine a digital representation geographically. I used a photogrammetry technology as my measuring device to orbit and to observe the tidal changes over time. Since the optical scanning performance of the measuring tool was disturbed by the flux state of reflection from the flowing river surfaces, this investigation had unexpectedly revealed an hidden island that is thus generated or  recognised
by the machine’s failure / blind spot / mind to the shifting boundary between water and land.


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