This weeks lab we worked with the Pix4D program in order to complete some post processing and to implement the idea of ground control point corrections. The first portion of the lab dealt with understanding projection and correctly importing the images into the program. Then we had to import the ground control points into the program with emphasis on projection and coordinates. After both the images and the GCP points were imported we had to input corrections for the GCP points to be accurate. This process required selecting each ground control point and then locating it inside of multiple overlapping images. The images below show the corrected ground control points on the mini box on the right side.
After the post processing was complete and the data was corrected using the ground control points we were instructed to generate a layout of the ground control points. To accomplish this task we utilized ArcGIS Pro to show the overall data along with detailed insets that show the location of each ground control point.
