Using QGIS to Segment Orthomosaics and Extract Drone Data

In this video we use QGIS to segment an orthomosaic collected by drone imaging, create a vegetative index layer, and extract data as numeric values. Specific times described below -1:20 Creating a project in QGIS -1:45 Uploading orthomosaics into QGIS -3:10 Creating a false RGB layer -6:20 Segmenting the orthomosaic to outline your plots -9:10 Extracting reflectance data from a layer -11:15 Developing a vegetative index layer -14:15 Choosing a threshold for the vegetative index to use as a soil mask -17:45 Creating the thresholded layer for the vegetative index -22:46 Extracting a green area estimate from the thresholded vegetative index layer
