Juniperus excelsa subsp. Polycarpos, which Iranians known as the Persian juniper located in the northeast of Iran.ALOS satellite using multispectral band (AVNIR-2) with 10-meter resolution and Panchromatic band (PRISM) with 2.5-meter resolution has been used.Two kinds of method (pixel and object) for tree extraction have been calculated. Object orientedSupport Vector Machine (SVM) algorithm has...

Several soiland atmospheric correcting variants of the normalized difference vegetation index (NDVI) have been proposed to improve its accuracy in estimating biophysical plant parameters. In this study, a sensitivity analyses, utilizing simulated and observational data, was conducted on the NDVI and improved variants by analyzing the atmospheric-and soilperturbed responses of each VI as a conti...

Yield prediction before harvest is one of the important issues in terms managing agricultural policies and making right decisions for future. Using remote sensing techniques yield estimation studies steps many countries to reach their 21st-century targets. The aim this study develop a wheat model using Landsat-8 Sentinel-2 satellite data. In study, development stages winter were examined with h...

The Normalization Difference Vegetation Index (NDVI), for many years, was widely used in remote sensing the detection of vegetation land cover. This index uses red channel radiances (i.e., 0.66 μm reflectance) and near-IR 0.86 reflectance). In heavy chlorophyll absorption area, is located, while high reflectance plateau canopies, Near-IR situated. Senses channels (Red & Near- IR) read varia...

In the context of Bonn Challenge, Pakistan started Forest Landscape Restoration (FLR) in 2014. This study assessed growth performance and survival rate young plantations developed linear regression models by using Landsat-8 data. The results showed that fast-growing species such as Eucalyptus camaldulensis Robinia pseudoacacia have shown a good compared to Pinus roxburghii Cedrus deodara. veget...

Clarifying the spatial heterogeneity of urban heat island (UHI) effect is great significance for promoting sustainable development. A GeoDetector was used to detect influential natural and society factors. Natural factors (normalized difference vegetation index (NDVI), soil-regulating (SAVI), normalized building (NDBI), modified water (MNDWI)) as well (road density (RDD), population (POPD)) wer...

Forest fires are severe disasters that cause significant damage in the Republic of Korea and entire world, an effort is being made to prevent forest internationally. The budgets 3.38 million USD every year fires. However, average 430 wildfires occur nationwide annually. Thirty-eight percent fire budget used for restoration. Restoring afforestation affected areas a top priority. This study aimed...

Studies on the resilience of mangrove forest areas are becoming popular in Indonesia, despite implementation Hyper Spectral Remote Sensing method identifying changes vegetation index values based Normalized Difference Vegetation Index (NDVI), Soil Adjusted (SAVI) and Enhanced models (EVI) unreached need to be done add database so that it becomes a reference for further research. Considering thi...
