1. 1. Evaluated density estimates of young forest stands using high resolution 2D imagery from UAV

   Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Resource Management

   Författare :Victor Kingstad; [2020]
   Nyckelord :UAV; forestry; inventory; survey; cleaning; tending; PCT; pre com-mercial thinning;
