Remote sensing is a method to collect data of any object or area of our planet from a distance typically from satellites. As an applied tool, it has evolved historically in parallel with other various technological advancements. The revolution of remote sensing to obtain data from usage of air balloons to advanced satellites, the process of interpreting the collected data from different types of sensors and remote sensing satellites of a particular area through various programs are briefly explained. We will deal with the Earth’s observation from space-borne imaging sensors, encompassing sensors mounted on and imagery obtained from orbiting satellites. This research also focuses on the analysis and interpretation of the acquired data and imagery. This thesis looks at the data obtained from satellite Landsat 8 with the help of ArcGIS tool by observing the area named Mount Laguna, California for a period of 10 months. The climatic variations on Mount Laguna are captured from Landsat 8.
