Tracking the stockpiles of cells at the quarry using Pix4Dsurvey is highly accurate and efficient. Using Pix4Dcloud Advanced and Pix4Dsurvey, Sky Grid can return to the same site on a monthly basis to provide updates for the owners and it will still work out cheaper for the clients, rather than paying contractors to do the work every 3 months. Sky Grid summarized their results in a pdf report including the outputs of Pix4Dsurvey, which was easy for the site owners to use for breaking down the complexities of the dataset. Combined with the overlay comparison feature available on Pix4Dcloud Advanced, the changes to the landfill site can be easily identified, which is incredibly valuable in the evolving shape and use of the site. Sky Grid took advantage of the variety of functions in Pix4D software which meant the team could show their client exactly what Sky Grid's findings were and represent the site as never seen before. completed the assignment successfully. Uploading the images to Pix4Dcloud Advanced, the processing stage of this workflow was rapid, completed on Pix4D servers within 5 hours. This dataset was then imported to Pix4Dsurvey. The point cloud was incredibly detailed and clear, and the grid creation was automatic, leaving no room for human error from manually creating the grid. Not only were the results clear but they were also accurately georeferenced. Harnessing the outputs of Pix4Dcloud Advanced with Pix4Dsurvey, Sky Grid quickly separated the ground and non- ground parts of the point cloud and created a grid of points with just 500 millimeters spacing across the terrain. This gave Sky Grid a dense set of points that could be imported into CAD software, which Sky Grid used to create a contour map that they delivered, along with the produced a detailed orthomosaic, DSM, and QA report, to the client. In addition to this, Sky Grid provided a digital twin of the site for Sky Grid's client to explore and analyze.
