Mapping Indonesia’s Mangroves Over Time: A Multitemporal Classification Study

Mangroves are among Indonesia’s most vital coastal ecosystems, providing protection against erosion, serving as carbon sinks, and supporting biodiversity. Yet, their extent and condition are changing rapidly. To better understand these dynamics, we conducted a multitemporal classification analysis of five key mangrove areas across Indonesia.

The main goal was to map and compare the spatial extent of mangroves in 2014 and 2022, allowing for the detection of changes in coverage over nearly a decade.

We used a combination of sensors from multiple satellites and geospatial data science techniques, including artificial intelligence (AI) algorithms, to classify our areas of interest into eight land cover and land use classes. Once the desired accuracy was achieved, we applied change detection and uncertainty quantification methods to provide informative metrics on ecosystem dynamics and management over time.
