Seconds to Anywhere
summary
Satellite archive reaches billion square kilometers, roughly seven times land area, with hundreds of revisit images per spot and snapshots taken about every 8 seconds in fast modes. WorldView-2 adds eight spectral bands enabling bathymetry to ~20–30 meters; raw geolocation is ~4–5 m, relative image accuracy ~0.43 m and post-processed mosaics ≈1.5 m. A half-petaflop GPU cluster (five racks) yields a 47x speedup for end-to-end processing. Haiti imagery is collected countrywide in a day, served via OGC web services and CDN within hours, reaching thousands of users.
