The number of Earth observation satellites launched in recent years is growing exponentially, along with the datasets they gather from free-to-access and commercial providers. The second edition of Practical Handbook of Remote Sensing is updated with new explanations and practical examples using the Copernicus satellite data and new versions of the open-source software. A new chapter and new applications have also been added. Thoroughly revised, the handbook continues to be a practical ＂how-to＂ remote sensing guide for those who want to use the technology, understand what is available, how to access it, and answer questions about our planet, but do not necessarily want to become scientific experts.
