AGIC Oct 2019 Short Course


Arizona Geographic Information Council (AGIC) Short Course

Friday, October 4th 2019 in Prescott, AZ



Instructors: Matthew Beckley, UNAVCO, Inc.; Chelsea Scott, Arizona State University

Course Description:

In this hands-on session, we will begin with an introduction to airborne lidar technology focusing on the basics of data acquisition, point clouds, point classification and filtering, and digital elevation model (DEM) generation and processing. We will then use OpenTopography (https://opentopography.org/) for a series of hands-on activities where participants will follow along and explore datasets of interest. OpenTopography is an NSF-funded project that streamlines discovery, access, and processing of open-access, high resolution topography datasets. Participants will use OpenTopography to process and examine different attributes of point clouds, construct raster DEMs, and perform topographic differencing on multi-temporal datasets to examine landscape change. As time and interest permit, we may do an additional demo with the open source CloudCompare software (http://www.cloudcompare.org/) which supports visualization and computations of lidar point clouds and other 3D datasets.
