Introduction
Multi-band UAS imagery is a key aspect of data analysis. Different color band combinations when used together can show critical information to the viewer who can then easily identify what that information really means. Two common multi-band combinations used are RGB , as well as False IR. Each of these colorband combinations are highly useful when used properly and both are able to give the viewer an immense amount of information about a peice of land when previus information would be invisible to the human eye.
Methods
For the purposes of this lab the process of creating our final deliverable product was fairly short and did not involve many operations. For the few operations conducted for this lab, I utilized the ESRI program of ARC GIS pro in order to create multi band composite raster layers which are shown below in the next section of this post.

Discussion
The usage of different bands when using ARC-GIS is critical to understanding how different color bands/wavelenghts portray information and what each band is good at showing. As you can see your typical RGB band combination on the right is great at showing vegetation but it is not as good at showing properties of vegetation such as thickness and areas where growth is not happening. A better band combination for what was mentioned would be using a False IR color band combination which better displays the properties of where growth of vegetation is occurring and not occurring.
