This document summarizes a kick-off meeting for Task 2.4 - 3D Modelling for harvesting planning. The task aims to generate a detailed interactive 3D model of the forest environment to evaluate accessibility and efficiency of harvesting technologies in mountain forests. It will run from July to December 2015 and involve 7 partners who will develop a harvest simulation tool based on the 3D forest model. The meeting covered objectives, scheduling, participant roles, and visualization technologies to be used in developing the interactive virtual 3D environment and deployment on mobile and machine displays.
