The Blue Marble Team
Introduced with the version 19 release of the Global Mapper LiDAR Module, the Pixels-to-Points tool creates a high-density 3D point cloud from an array of overlapping images, such as those collected by UAVs. Based on the principles of photogrammetry, the process identifies specific objects in multiple images and from multiple perspectives to generate the point cloud.
In this presentation, we walk through the steps for importing the individual images, assigning the necessary options and settings, and generating the point cloud. We also look at the process of detecting and reclassifying ground points as a prerequisite for creating a DTM.
Raster imagery often becomes the base of any mapping project simply because it is the clearest picture we have on a map. If that imagery is in the wrong location, that inaccuracy cascades into digitized vectors, all the way through a decision making process. The solution is to place the data in the correct location the first time, this session will cover just that. Geographic Calculator has a powerful georeferencing tool that allows for precise placement of control marks and takes advantage of high order polynomial transformations to suit everything from a small scale scan of localized area out to large scale continent views. This session will step through common georeferencing workflows.
