"Monitoring
environmental impacts and vegetation cover in mine sites are an important step
in remote sensing applications for mining management. Traditional aerial
platforms such as airplanes and satellites are not suitable for these
applications due to their low spatial and temporal resolutions. In this study,
a UAV equipped with a commercial camera (RGB & NGB) will be assessed for
ultra-high resolution image acquisition over an active coal mine site in South
Kalimantan, Indonesia. From these images, GNDVI (Green Normalized Vegetation
Indices) visible spectral indices will be calculated and evaluated for
vegetation fraction mapping. Furthermore, environmental changes will be
captured from the optical sensor mounted on the UAV. This provides evidence
that visible spectral indices derived from images acquired using a camera
onboard a UAV flying at low altitudes are a suitable tool to use to
discriminate vegetation health and monitor environmental changes in mine site. This
study opens the doors for the utilisation of this technology in precision mine
management applications such as reclamation management in which accurate
vegetation fraction mapping is essential."
