The main objective of this research is to investigate the potential combination Sentinel-2A and ALOS-2 PALSAR-2 (Advanced Land Observing Satellite -2 Phased Array type L-band Synthetic Aperture Radar-2) imagery for improving accuracy Aboveground Biomass (AGB) measurement. According current literature, kind investigation has rarely been conducted. Hyrcanian forest area (Iran) selected as case study. For purpose, a total 149 sample plots study were documented through fieldwork. Using imagery,...
The Reducing Emissions from Deforestation and Degradation (REDD+) projects aim to prevent deforestation greenhouse gas emissions as a policy combat climate changes. This article evaluates changes the Zagros' Forest cover in 20 years predicts implications of implementing REDD+ project next two decades. Using Landsat maps logistic regression model potential for forest transfer non-forest regions was modeled identify at risk deforestation. A Markov chain implemented predict Receiver Operating...
Pollarding oak trees is a traditional silvopastoral technique practiced across wide areas of the northern Zagros mountains, unique and vast semi-arid forest area with strong cultural ecological significance. So far, effects pollarding on tree structure in terms DBH (diameter at breast height)~H (height) relationships within typical cycle, which often lasts 4 years, has not been scientifically described. Here, we combine field inventories H obtained from photogrammetric UAV flights for first...
Remote sensing-assisted monitoring of forest health entails methods that can provide up-to-date and accurate information on decline mortality individual trees, while maintaining time cost efficiency. However, the trade-off applying consumer-grade UAV-RGB data as most affordable accessible source at catchment level is constrained by its poor spectral content. We developed a method based fusion with space-borne Sentinel-2 Multispectral Instrument (MSI) tree crowns, specific target supporting...
Abstract Regular biomass estimations for natural and plantation forests are important to support sustainable forestry calculate carbon-related statistics. The application of remote sensing data estimate has been amply demonstrated but there is still space increasing the efficiency current approaches. Here, we investigated influence field plot sample sizes on accuracy random forest models trained with information derived from Pléiades very high resolution (VHR) stereo images applied in an...
The semi-Mediterranean Zagros forests in western Iran are a crucial source of environmental services, but severely threatened by climatic and anthropological constraints. Thus, an adequate inventory existing tree cover is essential for conservation purposes. We combined ground samples Quickbird imagery mapping the canopy portion unmanaged Quercus brantii stands. Orthorectified was preprocessed to derive set features enhance vegetation signal minimizing solar irradiance effects. A recursive...
Plantations established in highly-pollutant industrial areas have a crucial role to absorb greenhouse gases, particularly CO2. A thorough monitoring of their aboveground biomass and carbon balance is essential ensure beneficial effects. This can be operationally supported by using combination field multispectral stereo remote sensing data provide surface height information with high resolution wide coverage. We estimated the fresh dry sequestration from pairs Pléiades satellite imagery...
Background: Traditional field-based methods of measurement biomass and carbon storage face difficulty in collecting time-consuming expensive, suggests the use remote sensing-based techniques. It estimates economic value aboveground (AGB) using satellite sensing across Hyrcanian forests Iran. Methods: The Landsat-8 OLI sensor data were combined with allometric information 186 circular sample plots. AGB was calculated at plot level collected specific volumetric mass for species studied area....
