Abstract:

Abstract-Landsat satellite imagery has been a critical resource for Earth observation since its first launch in 1972, providing valuable data for monitoring and managing Earth's natural resources. The Landsat program, managed by NASA and the U.S. Geological Survey (USGS), offers high-resolution images of Earth's surface, helping to track changes in land use, vegetation, urban expansion, water resources, and environmental health. The data captured by Landsat satellites plays a crucial role in diverse fields such as agriculture, forestry, urban planning, disaster management, climate change studies, and environmental monitoring. Landsat satellites orbit the Earth at an altitude of approximately 705 km, capturing multispectral images across a wide range of wavelengths, including visible, infrared, and thermal bands. These images are highly useful for analyzing various physical and environmental conditions, providing insights into land cover classification, vegetation health, and changes in the Earth's surface over time. The data collected by Landsat sensors, such as the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS), are made available to the public through the USGS Earth Explorer platform and are widely used by researchers, policymakers, and businesses around the world.
