چکیده
Abstract Accurate mensuration of forest stands for pre-harvest planning will pose high costs if carried out by a professional forester as an on-site evaluation. The could be reduced person with limited expertise collect the required data using smartphone-based system such TRESTIMA® Forest Inventory System. Without prior information, field sample sufficient number measurement points over whole stand should selected, so that entire variation covered. We present and test rational framework based on selecting sampling locations according to auxiliary data. As variables, we use various spatial sources indicating forests’ structural or spectral variation, well previously predicted inventory variables. construct two variants schemes local pivotal method, weighted data, compare results simple random (SRS) corresponding sizes. According our findings, benefits depend considered stand, species timber assortment. leads generally improved up three times higher efficiency (i.e. lower variance) compared SRS. conclude applying has capabilities in rationalizing efforts little drawbacks, consequently providing potential improve similar size possibility non-specialists inventory.

Forest Stand Types Classification Using Tree-Based Algorithms and SPOT-HRG Data
Forest types mapping, is one of the most necessary elements in the forest management and silviculture treatments. Traditional methods such as field surveys are almost time-consuming and cost-intensive. Improvements in remote sensing data sources and classification –estimation methods are preparing new opportunities for obtaining more accurate forest biophysical attributes maps. This research co...
متن کاملA Smartphone-Based Driver Safety Monitoring System Using Data Fusion
This paper proposes a method for monitoring driver safety levels using a data fusion approach based on several discrete data types: eye features, bio-signal variation, in-vehicle temperature, and vehicle speed. The driver safety monitoring system was developed in practice in the form of an application for an Android-based smartphone device, where measuring safety-related data requires no extra...

Small-area estimation (SAE) is a concept that has considerable potential for precise estimation of forest ecosystem attributes in partitioned forest populations. In this study, several estimators were compared as SAE techniques for 12 counties in the northern Oregon Coast range. The estimators that were compared consisted of three indirect estimators, multiple linear regression (MLR), gradient ...
