Accurate information about geometric properties of a forest road is essential for the sustainable forestry and transportation
safety. In this study the ability of airborne Lidar in detecting vertical...
Predicting the earthwork width and determining the annual growth loss due to forest road construction using artificial neural network and ArcGIS
area of road earthwork hillside slope roadside rock share
2016/8/2
The area of forest destruction as well as the annual growth loss due to road construction before constructing a road was predicted. To do this, road cross sections of 88 points along the 10 km propose...
