Detecting Change in Point Cloud Data (ft. David McKittrick) | GeoIgnite 2022

The increase in the availability of high-resolution lidar and other point cloud datasets has given rise to the use of this data for detecting change in the environment over time. Continual improvements in airborne technology and the miniaturization of the requisite sensors has cultivated a nimble new branch of the industry that provides cost-effective data collection services virtually on demand. This ability to employ temporal analysis of the geospatial landscape has applications in forestry, agriculture, mining, urban planning, civil engineering, and many other fields. In this presentation, we use Global Mapper Pro to explore two scenarios in which change has occurred at different scales, and subsequently, we will consider two different procedures for identifying this change. _ A big thank you to Blue Marble Geographics for being a SILVER sponsor of GeoIgnite "Winter Geo" Canada's National Geospatial Conference 2022. _ Topic: Detecting Change in Point Cloud Data Speaker: David McKittrick, Outreach & Training Manager for Blue Marble Geographics Organization: Blue Marble Geographics _ David McKittrick is Training and Outreach Manager at Blue Marble Geographics in Hallowell, Maine.
