Since I started working at Planet, I kept hearing about Cloud Optimized GeoTIFFs (COGs). My colleague Chris Holmes even wrote a post explaining what they are and how they’re useful. I decided to implement a Go library to be able to work with COGs. Much of Planet’s satellite imagery is in the GeoTIFF format, including this nice image of Los Angeles from our February 2018 Global Basemap:

As a first step to writing a library, I needed to learn about 1) Cloud Optimized GeoTIFFs, 2) GeoTIFFs in general, and 3) even more general than that: TIFFs. I’ve always found binary file formats intimidating they just look like gibberish when you dump them into the console! But there’s logic in that gibberish. Here’s what you can gain from my exploration of this 30-year-old file format.

The RRS James Clark Ross (JCR) made her final call to her homeport of the Falkland Islands on Monday March first, since after thirty years of service, the JCR will be sold at the end of her 20/21 Antarctic season.
The Falkland Islands are the final stop on the ship’s five and a half month mission to deliver scientific and operational staff to Antarctica, and to resupply the UK stations in Antarctica for another year.
