Remote Sensing Introduction
Discover the power of Remote Sensing, using satellite - or aircraft- based sensor technologies
What you will learn
Understand basic concepts of Remote Sensing.
Understand the physical principles behind the interaction of EM radiation and the multiple types of soil cover (vegetation, water, minerals, rocks, etc.).
Understand how atmospheric components can affect a signal recorded by remote sensing platforms and how to correct them.
Download, pre-processing, and satellite image processing.
Remote sensor applications.
Practical examples of remote sensing applications.
Learn Remote Sensing with free software
Remote Sensing (RS) contains a set of remote capture techniques and information analysis that allows us to know the territory without being present. The abundance of Earth observation data allows us to address many urgent environmental, geographical and geological issues.
Students will have a solid understanding of the physical principles of Remote Sensing, including the concepts of electromagnetic radiation (EM), and will also explore in detail the interaction of EM radiation with the atmosphere, water, vegetation, minerals and other types. of land from a remote sensing perspective. We will review several fields where Remote Sensing can be used, including agriculture, geology, mining, hydrology, forestry, the environment and many more.
#AulaGEO This course guides you to learn and implement data analysis in Remote Sensing and improve your geospatial analysis skills.
