WLIA 2020 Annual Convention

LiDAR is becoming common place in the geospatial spatial field, this workshop will cover the basics of LiDAR. First, there will be an overview of what LiDAR is, how it works, and the different types of sensors and their capabilities. Followed by an explanation of how the data from the sensor is processed, calibrated, and validated. Next will be a discussion of how the data is classified and the types of end products, such as DEM’s and contours, that can be generated from the data. It will also include a look at the many different products that can be created from LiDAR data. Lastly, there will be an overview of the many different applications that LiDAR can be used for and a discussion on how existing LiDAR data that you have can be re-purposed. The workshop will include looking at data from both fixed wing sensors and higher resolution data from static and mobile platforms.

This presentation will compare three approaches for acquiring geospatial data for site specific projects. Data collected from UAS will be compared and contrasted to other aerial platforms. We will distinguish between LiDAR and photogrammetry, and discuss the most appropriate approach to various project types. We will cover the topics of expected accuracies and best practices for generating and using elevation datasets and planimetrics.
