A proposed decision support tool for wood procurement planning based on stereo-matching of aerial images
In Sweden the cap portion of the harvested stem volume derives from Non-Industrial Private Forest (NIPF) owners. In the current study a Decision Support Tool (DST) for wood procurement planning based on stereo-matching of aerial images is presented. Two stages are described, namely (1) automatic seg...
