Development of Vegetation Changes Monitoring Application in Kalimantan Island (2000-2021) with MODIS Satellite Imagery using Streamlit Platform

Abstract

Kalimantan Island is one of the largest islands in Indonesia, with high natural and mineral resources. Therefore, the mining industry and clearing of forest areas for oil palm plantations cause a decrease in vegetation. However, the existence of vegetation has a positive impact on the sustainability of the ecosystem. For this reason, monitoring the vegetation on the island of Kalimantan regularly using remote sensing data is necessary. This study uses MODIS Nadir BRDF-Adjusted Reflectance Daily 500m (MODIS/006/MCD43A4) satellite imagery consisting of bands 1–7 and 500 meters resolution. Data calculation using the MNDVI algorithm, which can reduce atmospheric effects and, at the same time, adjusts parameters for reflectance data not affected by the atmosphere. Then, data processing was carried out with cloud masking and clipping using the boundaries of Kalimantan, and the results were classified into four classes. The monitoring of vegetation changes will develop into a web-based application. Applications are made using the Streamlit framework and can be accessed by anyone needing data on vegetation changes on the island of Kalimantan from 2000 to 2021.
