High-Resolution Mapping of Forest Carbon Stock Using Object-Based Image Analysis (OBIA) Technique
Journal of the Indian Society of Remote Sensing, 2020 This study assessed and mapped the aboveground tree carbon stock using very high-resolution satellite imagery (VHRS)—WorldView-2 in Barkot forest of Uttarakhand, India. The image was pan-sharpened to get the spectrally and spatially good-quality image. High-pass filter technique of pan-sharpening was found to be the best in this study.

Rural Road Extraction using Object Based Image Analysis (OBIA): A case study from Assam, India [PDF]
Advances in Cartography and GIScience of the ICA, 2019 Abstract. Rural roads in India have been considered as significant component for overall rural development. In India, the status of rural road connectivity is not up to the mark in some of the states. For providing better connectivity in the rural areas the information on roads are considered important.

Canadian Journal of Remote Sensing, 2023 The purpose of this research was to distinguish and estimate natural forest areas at Paraná, Brazil. Forest plantations (Silviculture) and natural forests have high annual vegetative vigor, as well as agricultural areas in the periods of agricultural harvests, which can bring classification errors between these classes of Land Use and Land Cover (LULC),
