This tutorial is part 22 of the OSINT At Home series. The tutorial covers the practical use of Google Earth and Sentinel Hub to calculate the size of specific areas using free satellite imagery. The tutorial focusses on guiding you methodically through the usage of these platforms, allowing you to acquire accurate area measurements, a skill crucial for research, investigations, documentation, geospatial studies, and hobby endeavours. Being able to measure areas and lengths of objects on free satellite imagery is also useful if you’re building a house, mapping out a run or hike, or looking area size changes to your surrounding community from space. By the end of this tutorial, you should be adept at employing these tools to gather and analyse satellite imagery for your specific needs. For the case study in the presentation, I use three examples: 1) Building destruction seen on Google Earth Pro in Myanmar’s Mandalay. Location: , 2) Fire damage in Russia’s Siberia on Sentinel Hub. Location: , . Sentinel Link: 3) Carpark area size at London’s Heathrow Airport on Google Earth Online.
