Abstract

Measurement of forest carbon on the ground in a large scale is time-consuming and expensive. This research utilized remote sensing with Sentinel-2B image through its Vegetation Index and related those values with those obtained from field measurements and Terrestrial Laser Scanner (TLS). This study specifically compares the forest stand carbon value using TLS and field measurements and link it to the vegetation index. This study transforms the vegetation indices, i.e.: Transformed Vegetation Index (TVI), Normalized Difference Vegetation Index (NDVI) and Simple Ratio (SR) from Sentinel-2B imagery and relates them with field measurements and TLS. The calculation of carbon in forest stands using TLS revealed an average carbon of 151.35 ton/Ha. In contrast, in the field measurements, carbon was measured at 149.81 ton/Ha, and statistically, there was no difference between these two measurements. The relationship between the vegetation index and field measurements showed the best coefficient of correlation of TVI with (r) = 0.784 and (R²) = 0.524. The relationship between the vegetation index and TLS measurements showed the best coefficient of correlation of TVI with (r) = 0.759 and the coefficient of determination (R²) = 0.577.

Yohanes Budi Sulistioadi is an assistant professor in Mulawarman University, Samarinda, East Kalimantan. Initially trained as a forester in his home university, he turned his education path to the field of Geo-information Sciences in ITC Enschede and completed his PhD in Geodesy in The Ohio State University in 2013.

Since 1999, he worked with many kinds of geospatial and remote sensing data for natural resources management and environmental studies. His latest research grants including those from Center for International Forestry Research (CIFOR), Global Green Growth Institute (GGGI), Gesselschaft fur Zussammenarbeit (GIZ), USAID Sustainable Environmental Governance across Regions (SEGAR) as well as many government agencies in East Kalimantan.

His research interests include hydrology, environmental modeling and various applications of geospatial and remote sensing data.
