I am looking to characterize the vegetation habitats of a very small island.
I have aerial images of the island, as well as LiDAR data in the form of LAS and XYZ files. I am able to generate both a DSM and DEM from the las files, and by subtracting the DEM from the DSM, I get the resulting layer of vegetation height.
I am wondering how to use the aerial images to quantitatively verify the findings, as well as use them to augment the classifications.
For example, we are characterizing the island into 4 main habitats: forest, fern, grass, and barren. Each has lower vegetation.
How should I use the aerial images to sample known areas of forest or fern to then obtain representative values for vegetation height for that particular habitat class.
Any help is greatly appreciated.
