This tutorial is part 7 of the OSINT At Home series. It covers how to make a satellite image time lapse.

Satellite imagery plays a core role in the verification, analysis and investigation of information for the purposes of research. One of the lead factors with satellite imagery is the ability to compare different dates to see when something was at a given location, and when it wasn’t, or, in some of the examples, when new buildings appear on satellite imagery, watching vessels move, or identifying solar panels and their movement through satellite imagery.

Using the satellite imagery time lapse is a great way to identify change on the ground, and through mastering this skill, it will inevitably help any of those looking to verify incidents that happened on the ground, verify footage seen on social media, or claims in the news. It can also help with research and investigations in other fields, such as using satellite imagery in environmental journalism to identify deforestation, business journalism to identify mining growth, or research on urban sprawl and development by using the satellite imagery to indicate spread of urban areas over time.

While this tutorial only covers an introductory use of Sentinel Hub's time lapse tool, it is recommended that further research be done on specific use cases to help you in your research.

The OSINT At Home series is useful for those looking to find digital breadcrumbs and pick up some methods of open source intelligence (OSINT), digital investigations and good old plain research. No matter who you are, or where you are in the world, you can follow these tutorials from home with publicly available information to answer questions such as who, what, where and when.
