Use of LiDAR data during multi-annual periods for estimating forestry variables

摘要: Aim of study: To test the use LiDAR data from a single acquisition in order to estimate volume overbark variations ina 5-yr period Pinus radiata D. Don. Area study : Province Bizkaia Autonomous Community Basque Country (Spain). Material and methods Two field plot measurements were made 2011 2015 two wood models (one for each year) fitted using metric variables 2012 points cloud. The applied 26.59 m raster covering area increase at pixel was calculated by subtraction. Main results estimated volume, when added timber extracted during under consideration, yielded an average 13.74 3 ha -1 yr , which corresponds growth P. that area. harvest this procedure largely coincides with actual same period. value R 2 (85%) model is similar obtained other studies. However, as expected, one (80%) significantly lower. Research highlights can be flight provided plots subjected kind included models.
