Volumetrics with UAS Data
Introduction This lab focuses on the calculations of volumes using UAS data. I use data retrieved from the wolfpaving data set that was seen in previous labs and go through the process of generating volumetric data in both Pix4D and ArcMap. Methods Pix4D Method To start I opened Pix4D and the wolfpaving project file. The process here is explained in more detail in the "Processing Data in Pix4D with no GCPs" lab. Turn on the point cloud and turn off the cameras, rays, and tie points for easier viewing. On the left side of the window there is a cylinder shaped icon that will say "Volumes" as seen in Figure 1. Figure 1: Volumes button From there, there will be a "New Volume" button in the volumes window (shown in Figure 2) Figure 2: New Volume Clicking on that will allow you to click on the point cloud to draw a polygon around the base of whatever volume you are trying to calculate. Right clicking will finish the polygon and allow y
