Lecture

Earth Observation Sensors: Spectral Indices & Exercise Introduction

Description

This lecture delves into selecting the appropriate data for Earth observation, covering topics such as spatial resolution, sensor types (satellite, drone, etc.), and data pricing. It explores the differences between active and passive sensors, emphasizing their applications and advantages. The lecture also discusses spectral indices, including multispectral and hyperspectral sensors, and their significance in extracting information about vegetation and other materials. Various spectral indices like NDVI, SAVI, and PVI are explained, along with their applications in studying vegetation health and other properties. The lecture concludes with an exercise introduction on computing vegetation indices and analyzing temporal NDVI values of different regions.
