For some reason it didn't come to my attention until recently (less than a year ago) that the entire Landsat imagery plus a lot of data from other Earth orbiting spacecraft is freely available for download at http://earthexplorer.usgs.gov/ . Maybe this is because for a long time it was more difficult to find good and freely available global maps (or get data to make maps) of the Earth than it was for other planets/satellites - I somehow was under the impression that the vast majority of Earth imagery was commercial.
The Earth is visually a really spectacular planet (in my opinion possibly even the most photogenic body in the entire solar system) so it's possible to get spectacular results by downloading some of this data. The data can be selected by spacecraft, instrument, location, months/years, cloud cover percentage etc. Data is available from several Landsat satellites but the best data is from Landsat 7; Landsat 5 is also good. This is multispectral data with a resolution of 30 meters/pixel. Here is an experimental and spectacular 12 frame mosaic showing southern Greenland (10% the original size): The full size version (19000 pixels square) plus additional information can be seen in this blog entry at the Planetary Society website. This image shows a spectacular and complex 'maze' of long and narrow fjords and islands, narrow valleys flanked by steep mountains, glaciers and glacial rivers, countless lakes and ponds and in general a landscape that has been shaped by advancing and retreating glaciers, depending on climate. One important thing to note is that overall this data turned out to be easier to process than is typical for data from other planets. |

Here is another film compiled from ISS time-lapse sequences converted to real-time ( except for night sequences which are x2 )
4k version on Youtube ...and an earlier effort I forgot to share... 4k version on Youtube A single orbit of Earth by the International Space Station in real-time, 408km above the surface. Made with 9,966 time-lapse photographs from ISS Expedition 57, taken on October 6th 2018. -------------------- |

Sean. You are a great a film lover. Dr. Strangelove is one of my favorite films. Your video almost made me cry. Thanks.

Nice to see the oblique clouds with the sun-glint and shadows in "Earthbound" - key ingredients for realistic simulations. Also just plain fun and inspiring to watch.
In the beginning of "Orbit: Uncut", it's neat to see the color of the sun shift from orange/yellow as it rises through the troposphere, then switches over to white and blue as it enters the stratosphere with the ozone, then back to white as it gets up higher. The idea of a blue sunrise is really out of this world. -------------------- Steve [ my home page and planetary maps page ]

Looks great. Can you say what the speed up is vs real-time? Also, any idea what the two bright stars/planets(?) are at https://youtu.be/DETb68nNZ2A?t=306 |

Time-lapse cadence varies and some shots I've doubled playback because cadence offset was irregular and returned stutters.
I'll dig into the file dates for the planets shot. My guess is Moon & Venus. Looks great. Can you say what the speed up is vs real-time? Also, any idea what the two bright stars/planets(?) are at https://youtu.be/DETb68nNZ2A?t=306 -------------------- |
