Final Data Products (AT309)

  Pix4D Final Data Products Michael Holland Introduction              Throughout the Fall Semester of AT309, my lab partner, Saurav Dalvi, and I completed multiple 3D scans and mapping missions using both a Skydio S2+ and Mavic 2 Pro to engage in data collection. These 3D scans and mapping missions involved the drone flying in a predetermined path to collect individual images of the area we wanted to scan. After collecting these images, Saurav and I would save them to a personal external hard drive. From here, we were able to put them into a mapping software called Pix4Dmapper, which took our individual images and stitched them together to make one large 3D model. If our scan was a mapping mission, we could then use a software called ArcGIS Pro to turn out processed data into a cartographically correct map. While engaging in data collection, and processing, we were able to see the differences between platforms of the...

Cartographically Correct Maps, DSM and Orthomosaics (AT309 Week 15)

Image
 In this week's lab, we completed three maps. In each of these maps, I included a title, insets, north up arrow, scale, legend, metadata, and watermark when applicable. Figure 1 shows the first map where we have a shaded Digital Surface Model with a transparent DSM on top of it. This shows the terrain elevation in a visual way as it color codes it and you also have shaded terrain. It contains an inset map showing where the mining area is found. Figure 1- Shaded DSM Figure 2 shows an orthomosaic map of the same area as Figure 1. We also added zoomed-in insets of all of the GCPs in the area. This shows their exact location. It also had lines connecting the inset to the proper GCP so you could tell where they came from. Figure 2- Orthomosaic Map Figure 3 shows another Orthomosaic Map of the same area, but this time we took away the insets of the GCPs and added gridlines to the map.
