Arroyo Preserve Change Detection_edited.jpg

Repeat Station Imaging (RSI) is a method of acquiring imagery for change detection. During flight, GPS waypoints are used to trigger the camera shutters. Multiple images of the same location over time are merged with the changes shown with distinct colors.

Collecting MSI data for the same location at the same time of year is among the most established

and scientifically proven method for envrironmental monitoring over time.

The scientists at FireWatch have used this technique for the U.S. Navy to study vegetation

and climate change on San Clemente Island over the past few years. 

Nature preserves, open space and urban forests are dynamic, living resources that face increasingly abrupt changes and threats.


Aerial imaging can help meet the challenges posed by escalating rates of change associated with a warmer, drier climate and increased human population. 


A key diagnostic for wildfire prevention is monitoring changes in vegetation that has become stressed over time. 


Field teams can then investigate and potentially intervene before a small-scale problem becomes more widespread.
