Canopy Height and Snow Depth¶
Canopy Height Model is a popular raster product from lidar data. It can be derived from differencing DSM and DEM. Snow depth is another raster product of interest. This is derived by differencing snow-on DEM and snow-off DEM.
We will difference the appropriate elevation model to derive vegetation height and snow depth. To begin, let’s load the necessary packages for this tutorial.
#import packages import os import numpy as np #plotting packages import matplotlib.pyplot as plt import seaborn as sns import hvplot.xarray #geospatial packages import geopandas as gpd #for vector data import xarray as xr import rioxarray #for raster data import rasterstats as rs
