The purpose of this weeks lab was to create GCPs for use at a later date at a place in Tomah, Wisconsin. The GCPs were made of a heavy duty black plastic that does not rot as plywood does, this increases the life of the GCPs. Other materials used include pink and neon spray paint, a stencil made of plywood, sheets to protect Professor Hupy's garage floor and a table saw. The plastic came in large black sheets and they were cut into 2 foot by 2 foot sections. The stencil was placed on one side, sprayed with pink and allotted time to dry, then the other side was done and a number was added with the neon green. In total 16 GCPs were made and the entire process took just over a half hour.
A ground control point is a point of the earth that has a known geo-referenced location. They are used to ensure data accuracy and integrity and they are commonly used when taking photos using a UAV or other aircraft. Equally spaced out GCPs can drastically increase the accuracy of aerial map generation for a specific area of interest. Figure 1 below shows the first GCP that was created, while figure 2 displays how the class worked together doing many different steps at the same time. Figure 3 shows all of the 16 finished products and finally figure 4 shows some spray paint skills from a classmate that says "UAS."
