Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring whether it has reflected and emitted radiation at a distance (typically from satellite or aircraft). In simpler words, a flowchart is a diagram that represents a set of instructions. Flowcharts normally use standard symbols to represent the different types of instructions. These symbols are used to construct the flowchart and show the step-by-step solution to the problem. As the remote sensing image illustrates, Remote sensing is the art and science of making measurements of the earth using sensors on airplanes or satellites. You can create your own flowchart symbols in EdrawMax Online and later export your designs into multiple formats, including PNG, JPEG, PDF, Visio, HTML, or MS Word.
