satellite data

Planet Labs, Matt's former company and a very cool project that I'm surprised to find I haven't blogged about explicitly previously, has a fun blog with company news and demonstrating cool uses of and findings from their high-frequency land imagery data from their flock of small satellites. They recently featured an awesome use of satellite data to measure trade between China and North Korea via counting containers at border crossings in photos from this year and last. Economists out there involved in the harrowing task of accurately measuring trade and related quantities may want to consider this source of data!

The funniest thing about the post, though, is that apparently the Washington Post thought comparing photos from a Saturday and Sunday at the end of the lunar new year holiday week to photos from a more normal time the year before was a reasonable way to measure the time trend in trade levels... *Sigh*
