A workflow for combining airborne lidar, optical satellite data and National Forest Inventory (NFI) plots for cost efficient operational mapping of a nationwide sample of 5 × 5 km squares in the National Inventory of Landscapes in Sweden (NILS) landscape inventory in Sweden is presented. Since the areas where both satellite data and lidar data have a common data quality are limited, and impose ...

regeneration and forest durability guarantee is one of the most important aspects of forest sustainability and it should be placed in forest plans priority. to compare regeneration in the two grazed and non-grazed forest, baghe-shady forest located in khatam city (it has the preservative regions that they are 20 years old), yazd province, central of iran was selected. for this purpose, 60 sampl...

To detection of suitable sampling method to study tree canopy cover in the northern Zagros forest, Baneeh region forest, Kurdistan province, and west of Iran was selected. 40 square sample plots one hectare (100×100 m) were selected and perfect inventoried. In every sample plot the position of tree, kind of species and two diameter of crown (m) were recorded. To study of canopy cover different ...

The assessment of the quantitative and qualitative changes, the result of the impacts imposed by natural factors, and human interventions during specific sampling periods has a substantial influence on nature, management method and tending operation of every region’s forests. The present research was carried out in Golestan province forests (Iran) over an 11- year period and the obtained statis...

This paper evaluated the feasibility of a terrestrial point cloud generated utilizing an uncalibrated hand-held consumer camera at a plot level and measuring the plot at an individual-tree level. Individual tree stems in the plot were detected and modeled from the image-based point cloud, and the diameter-at-breast-height (DBH) of each tree was estimated. The detected-results were compared with...

this paper attempts to examine the effect of water spreading on soil physico-chemical properties, and vegetative characteristics of common mesquite. for this, on the basis of flood water discharge, three sections of lands were accurately selected at kosar water spreading experimental station, in tangestan, bushehr province. in each section, 6 profiles were digged out and studied; meanwhile soil...

This article presents the first models developed specifically for understanding the infiltration and interdiction of ongoing terror plots by undercover intelligence agents, and does so via novel application of ideas from queueing theory and Markov population processes. The resulting “terror queue” models predict the number of undetected terror threats in an area from agent activity/utilization ...
