The LiDAR Operations course was all about getting used to working with LiDAR data and how to edit it to make sure that it correct. The first lab for this course was to help us understand how to manage data within Microstation, Manage projects & blocks with TerraScan, working with the data within TerraScan, Data viewing, Point Classes, Point Classification, Automation & Macros. The second lab was about working with Coordinate Systems, Trajectory Management, Analyzing Flightline Misalignment, Calibration Data Selection & Preparation, Boresight & Sensor Calibration, and Elevation Adjustments.
The LiDAR Applications course had three different labs that needed to be completed. The first lab had me using the software TerraSolid and TerraScan to reclassify the airborne LiDAR from High Vegetation to Buildings or Buildings to High Vegetation. Then once that was completed there is a tool within terraSolid that creates 3D Building Vectors. Then after those building vectors have been created I had to edit them so they would look like buildings once they are brought into ArcScene. The second lab for this course was to use LiDAR data for hydrological modeling. "The use of LiDAR data for hydrological modeling is an established field with many government agencies either investigating or currently using LiDAR data for flooding risk assessment and water resource management. This lab will have you apply three fundamental hydrological analysis techniques (hydrological flattening, watershed mapping and flood modelling) to a LiDAR derived DEM (ground-only points). While the methods described in this lab are rather elemental in nature, the main goal of this project is to gain an appreciation of the benefits and drawbacks of LiDAR DEMs as they apply to hydrology."
