Wipneus last added a band 4 16-bit tiff to the gedeeld Jakobshavn collection on August 17th. However jp2 format will load ok in gimp but as 8-bit.
The latest cloud-free Landsat was acquired on 18-AUG-16, LC80080112016231LGN00. The 25th was totally clouded over; the next image is not due until Sept 1st, a path,row of 10,11. The next S1A is not due until Sept 4th (?). It's best if before and after have the same geometry.
Looking at the two Sentinel 2A's available after nukefix's remarkable S1A of the 25th, both were as cloudy as the Landsat, ie uninformative.
Yup, I scan the amazon cloud every day. Tail of current output:
dag : 2016/8/17 ( R025 , 100.0 , 0.95)
dag : 2016/8/20 ( R068 , 100.0 , 95.42)
dag : 2016/8/23 ( R111 , 77.13 , 97.68)
dag : 2016/8/24 ( R125 , 45.73 , 96.34)
dag : 2016/8/26 ( R011 , 1.89 , 100.0)
dag : 2016/8/27 ( R025 , 100.0 , 98.16)
Last two numbers are coverage and cloud percentage. None of the latest was of interest for ice watchers.
