EasyLidar: LiDAR GIS & maps
https://apps.apple.com/us/app/easylid...
Sixth tutorial of the advanced series. Teaching EasyLidar to recognise things: supervised classification of an orthophoto into land cover from drawn samples, accuracy and hectares per class, reusable signatures, a Core ML Deep Learning model that runs on the Mac, and the same idea applied to the terrain to detect geomorphons and your own landforms.
In this video you will learn to:
• Open the classifier and draw samples per class over the orthophoto.
• Classify by maximum likelihood and read the confusion matrix.
• Vectorize the result and get hectares per class.
• Save and reuse signatures.
• Apply a Core ML land-cover model with no samples, all on the Mac.
• Detect terrain patterns: geomorphons and your own classes with Random Forest.
