LiDAR Training - Winona

Monday, May 13 - Tuesday, May 14

Two-day LiDAR courses, including basics and advanced topics. The training is sponsored by Southeast and Southwest Regional Sustainable Development Partnerships and taught by Joel Nelson of UMN's Department of Soil, Water, and Climate.

Day 1: Basics of LiDAR

"Basics of Using LiDAR Data" is a one-day, part-lecture, part-hands-on workshop for GIS specialists. By the end of the session, participants will be able to download, view, and manipulate LiDAR data in its several provided forms. They will learn what LiDAR data is, limitations and error management, data formats, and data acquisition and management for various applications. Several tips and tricks of working with LiDAR and raster data in-general will be shared.

Audience

GIS specialists in local government units, government agencies, non-governmental organizations, and private companies.

Prerequisites

The course assumes you use ArcGIS and know how to import and manage files and layers, process geographic data, and understand what is raster data and how to process it.

Content

  • Data sources
  • What is LiDAR data and how is it collected?
  • Accuracy, errors and limitations
  • Identifying and managing errors
  • Where and how to get data
  • File management

Data properties

  • Coordinate systems
  • File formats: .SHP, GRID, .LAS and .LAZ
  • Data types - breaklines, contour, point cloud, raster/DEM

Software

Day 2: Advanced LiDAR

"Advanced LiDAR" is a one-day, part-lecture, part-hands-on workshop for GIS specialists. By the end of the session, participants will be able to extend skills learned from “Basics of LiDAR” into real-world applications utilizing the full suite of LiDAR data types. Attendees will be able to manipulate DEMs into a variety of terrain analysis and hydrology products, with particular attention given to LAS file management, visualization, and analysis. Several tips and tricks of working with LiDAR raw files and common issues will be covered.

Audience

GIS specialists in local government units, government agencies, non-governmental organizations, and private companies.

Prerequisites

Participants must have completed "Basics of Using LiDAR Data" before taking this workshop.
