looks that with the spread of processing methods and technology,
we can make things that were available only to national security agencies, once upon a time.
Take a look at the maps of the flight made May 18th:
one day to fly, one day to upload, one day for processing, (one day for grill party), one day to download.
Few of you might remember the 3km long flight with EasyStar (a single line), stitched with Microsoft ICE.
The map above is 2.2x2.2km. It took 746 photos to make this map.
Funny fact: if the aircraft would fly straight, the surface covered would be >16km2 instead of just 4.5km2 (null side overlap).
The overlap used was 70% side, 80% along.
