If you’ve spent any time looking at Google Earth, you’ll notice that the photography isn’t always perfect; sometimes things appear a little weird. Brooklyn-based artist Clement Valla looks for these oddities, scouring the site and viewing places from different vantage points. At certain angles, highways appear as if they’re melting, dipping into ravines and rivers. It’s trippy. He collects these images and calls them Postcards From Google Earth.
These scenes aren’t the result of glitches or of errors in the algorithm, but are the logical result of the system. Valla explains, “They are an edge condition—an anomaly within the system, a nonstandard, an outlier, even, but not an error. These jarring moments expose how Google Earth works, focusing our attention on the software.” 3D images like we see here are generated through texture mapping, where the flat satellite image of earth is applied over 3D terrain. Most of the time this is seamless, but sometimes, when the spaces are so different, things look wrong. Valla goes on to remark:
Google Earth is a database disguised as a photographic representation. These uncanny images focus our attention on that process itself, and the network of algorithms, computers, storage systems, automated cameras, maps, pilots, engineers, photographers, surveyors and map-makers that generate them.
