FULLY AUTOMATED GIS-BASED INDIVIDUAL TREE CROWN DELINEATION BASED ON CURVATURE VALUES FROM A LIDAR DERIVED CANOPY HEIGHT MODEL IN A CONIFEROUS PLANTATION
Crown Delineation Canopy Height Model (CHM) Local Maxima Curvature Slope Thiessen Polygons
2016/11/30
The generation of high resolution canopy height model (CHM) from LiDAR makes it possible to delineate individual tree crown by means of a fully-automated method using the CHM’s curvature through its s...

In forest area, there are few landmarks to be ground control points (GCPs) used for registration of satellite images or maps. Additionally,geographic information from the Global Positioning System (GP...
A FULL GIS-BASED WORKFLOW FOR TREE IDENTIFICATION AND TREE CROWN DELINEATION USING LASER SCANNING
LiDAR Laser scanning region growing algorithm GIS identification crown delineation
2015/8/7
Laser scanning or LiDAR data are increasingly used in forestry applications but also e.g. in urban environments or for building reconstructions. Huge point clouds are usually converted to a grid or ar...
