ABSTRACT
Vegetation is a renewable natural resource of landscape significance and economic expression and is part of most terrestrial ecosystems. Earth surface monitoring by Earth observation satellites can be crucial, and multispectral imaging cameras can be used in applications to determine indices that reflect conditions of vegetation vigor. The objective of this chapter is to obtain remote sensing data and perform normalized difference vegetation índex (NDVI) determination on image data from the CBERS-04A satellite, WPM camera. A simplified approach is used to determine the NDVI. By processing the images and mapping the results it is possible to visualize the variation of regions with low and high values of vegetation index at the monitored site near the Funil dam, Minas Gerais, Brazil. Solved exercises are presented to reinforce the knowledge about interaction between electromagnetic radiation and plant leaf, vegetation index determination, as well as about choosing a problem that can be studied with remote sensing and digital image processing of vegetation.
