Mapping of Mangrove Conditions Using Sentinel-2 Imagery

Abstract

Mangrove forests face significant pressure from human activities such as illegal logging, land conversion, and pollution. The impact of human activities on these ecosystems has raised concerns about the degradation and loss of mangrove forests. Therefore, research to understand the actual condition of mangrove forest density and area is very important. In recent years, advances in earth monitoring technology from satellite imagery have become increasingly important in mapping and monitoring mangrove ecosystems at large. This activity was carried out from October 03^rd to December 03^rd, 2022 in Pannikiang Island, Barru Regency by using the supervised classification method on Sentinel-2 satellite images to determine mangrove points, then applying the Normalized Difference Vegetation Index (NDVI) method. From the research results, it was obtained that the mangrove area was 1042261.12 m². Data analysis by calculating mangrove density and canopy cover. The condition of mangrove density on Pannikiang Island starts from very low density to very high density class. Each density class has a different area, each starting from very low density with an area of 49137.98 m², low density with an area of 41947.12 m², medium density with an area of 65916.9 m², high density with an area of 175578.60 m², and very high density with an area of 749854.47 m². Thus, this research is expected to make a significant contribution to the management, conservation, and protection of mangrove ecosystems on Pannikiang Island.
