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...

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...

Hyperspectral reflectance derived vegetation indices (VIs) are used for non-destructive leaf area index (LAI) monitoring for precise and efficient N nutrition management. This study tested the hypothesis that there is potential for using various hyperspectral VIs for estimating LAI at different growth stages of rice under varying N rates. Hyperspectral reflectance and crop canopy LAI measuremen...

The tsunami is a disaster that often occurs in Indonesia, there are no valid indicators to assess and monitor coastal areas based on functional land use cover which refers the biophysical characteristics of earth's surface. One recommended methods vegetation index. Vegetation index method from LULC can be used provide information how severe impact was area.In this study, an increase carried out...

Grain yield and quality assessment based on remote sensing throughout the growth cycle may contribute to achieve efficient sustainable wheat production. A trial was conducted test suitability of a multispectral sensor onboard an unmanned aerial vehicle (UAV) estimate yield, protein content, nitrogen (N) output in winter (Triticum aestivum L.). Furthermore, method improve predictions traits prop...

Satellite remote sensing technologies have a high potential in applications for evaluating land conditions and can facilitate optimized planning agricultural sectors. However, misinformed selection decisions limit crop yields increase production-related costs to farmers. Therefore, the purpose of this research was develop suitability assessment system using satellite sensing-derived soil-vegeta...

Recent land use changes, the absence of soil protection between crop periods, and extreme precipitation events have been highlighted as major influential factors in fluctuations sediment export last decades at catchment scale worldwide. In this regard, erosion fine-particle are two concerns nutrient loss water-quality decrease (e.g., increasing turbidity vector chemicals). However, while rainfa...

The performance of vegetation indexes derived from moderate resolution imaging spectroradiometer (MODIS) sensors is explored for drought monitoring in the forests of Northern Tunisia; representing a transition zone between the Mediterranean Sea and the Sahara Desert. We investigated the suitability of biomass and moisture vegetation indexes for vegetation water content expressed by the equivale...
