The Guide to Remote Sensing

Introduction

Have you ever looked at a map of your favourite place and through wow this is amazing? Well, today I will show you how you can get the map of your dreams in less than 30 minutes. Firstly, we need to gather the information from far away, at home in just a figure tip through remote sensing such as ships, UAV’s, satellites and aircraft.

One of the reachable, frequently used and worldwide covering remote sensing satellite data is via

Landsat 8 satellite took off in 2013, capturing the entire earth in 16 days. At worst, an amazing shelf-life of 5 years, despite its cost. At finest, a great way of understanding, learning and protecting our planet!! Despite running on two magical instruments the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS).

Landsat 8 calculates a series of occurrences throughout the electromagnetic spectrum. Many of

which fall within our perceived visible light. These observable parts count fewer than 50% of the Landsat 8 light-rays collection. That makes us become a curious bugger in terms of the motive of seizing frequencies that are not detected by us humans? To answer this, we must gain a bit of insight about Landsat’s gatherings.

Each electromagnetic spectrum section of Landsat 8 calculations is known as bands with a total of 11. Typically, a first glimpse of the band's dispersal may be random. However, the bandwidth are not uniform generating series of the unexpected intersection, nonetheless each having an explicit role. To reply to many queries of about our planet.
