Processing DSM and orthomosaic

“

Step Three DSM Orthomosaic and Index contains processing options for these assets. In this video, I'll explain how these various features work, and take a closer look at why you may want to set these options to specific parameters. And here we are at the DSM Orthomosaic Tab. The first option we have is Resolution. it starts with the Ground Sampling Distance at 1.5 for this data set. Now that's automatic. That comes directly from this particular map. The sensor and the camera and so forth that we used on this project. So let me just jump over here. I'm going to cancel this. Then I'm going to go to Process, Quality Report. And here you can see there is that information right there. That's the Ground Sampling Distance. In other words, the GSD, or Ground Sampling Distance, is the measurement between pixel to pixel. Center to pixel to center to pixel that are adjacent to each other. Now, that is an average. So that means if you were flying over terrain that was very hilly, it may be at…
