Maxar is a company that operates a fleet of satellites to capture high-resolution imagery of the Earth. They generate significant revenue from selling the imagery produced by these satellites. However, Maxar also runs an Open Data Programme, which provides access to over 100 imagery sets taken in areas before and after natural disasters in exchange for contact details. For those who don’t want to share their contact information, Maxar has published a freely available catalog with imagery URLs and metadata for 28 disaster events. The author then goes on to explain the process of downloading and analyzing the satellite imagery using various tools and technologies. They also provide information about the satellites used by Maxar and the number of images captured by each satellite for different events.
