about the authors


Practical Handbook of Remote Sensing was written by Dr Samantha Lavender and Andrew Lavender. It’s a book Samantha has wanted write for a number of years, something that could take a complete beginner through the basic scientific principles and teach them to do their own practical remote sensing. However, Samantha quickly realized to write a “How-To” book for people with no experience in remote sensing she needed someone who knew nothing about the subject to assist. This is where Andrew came in!

Together as the expert, and the non-expert, they’ve written this book. A journey that was interesting, challenging, occasionally argumentative and ultimately pleasurable; searching for the compromise between scientific theory and understandable language.

The book isn’t the first thing they’ve done together, apart from being married, they also run their own business, Pixalytics Ltd. Pixalytics is an independent consultancy company specialising in Earth observation and remote sensing. It combines cutting edge scientific knowledge with satellite and airborne data to provide answers to questions about the planet’s resources and behaviour.

Dr. Samantha Lavender has more than 20 years of remote sensing research experience. After a degree in oceanography and marine computer applications, Sam completed a PhD focused on the remote sensing of the Humber plume using airborne data. She became a researcher at Plymouth Marine Laboratory, a lecturer at the University of Plymouth and then Managing Director of ARGANS Ltd. In 2012, with Andrew, she formed Pixalytics Ltd and is the company’s Managing Director. She has an ongoing active interest in research alongside widening the community using remotely sensed data. She’s also a Director of Ocean Nourishment Ltd, an honorary Reader of Geomatics at Plymouth University and chairman of the British Association of Remote Sensing Companies (BARSC), having previously been chairman of the Remote Sensing and Photogrammetry Society (RSPSoc).

Andrew Lavender is a complete novice with remote sensing, with only a few months of experience. He works alongside Sam at Pixalytics Ltd, focusing on the administrative and social media side of the company. Prior to Pixalytics he had a long career within the NHS in a variety of IT Departments, before leaving to do a MA in Creative Writing. He is an active short story, poetry and flash fiction writer, and can occasionally be found performing his work and teaching creative writing.
