Vegetation mapping

From Lidar Magazine, 5.4.2021

Remote sensing analysts make maps by exploiting the relationships between variation on the ground and variation in the data being used to create the map (e.g., imagery, slope, aspect, elevation). Common data elements relied upon include tone/color, shape, size, pattern, shadow, texture, location, context, date, and height.

 

Until the advent of lidar, fine-scale measures of vegetation height were unavailable, or very expensively obtained from stereo imagery. Lidar data provides not only fine-scale measures of vegetation height, but also measures of crown shape, crown density, and canopy base height. Additionally, lidar data can provide high-resolution riparian corridor delineation, and measures of slope, slope position, aspect and elevation—all critical variables that affect vegetation species distribution, and are, therefore, useful in creating a vegetation map.

 

As a result, lidar data supports increased map detail, while also reducing costs and improving map accuracies. “Lidar data allows us to see underneath the canopy and measure the structure of the vegetation and the geomorphology of the landscape,” said Mark Tukman of Tukman Geospatial6, the mapping contractor for the Bay Area programs. “When used to develop independent variables for machine learning, mapping accuracies improve because so many of the lidar variables are significant predictors of vegetation type. In essence, lidar brings the landscape into focus”.
