farzaneh hadadi; Davod Ashourloo; Alireza Shakiba; Aliakbar Matkan

Articles in Press, Accepted Manuscript, Available Online from 17 April 2021


  Climate change is one of the most important challenges facing mankind. This phenomenon has already had significant impacts on agricultural products in most parts of the world, especially arid and semiarid regions. Also, average temperature has risen in many regions in recent decades. Nowadays, in various ...  Read More

Investigation of the saturation effect of vegetation indices in LAI estimation of crops

Maedeh Behifar; Mohsen Azadbakht; Farzaneh Hadadi; AliAkbar Matkan

Volume 11, Issue 1 , May 2019, , Pages 33-48


  Vegetation indices are used to estimate vegetation parameters from satellite images. Despite their capabilities, performance of some vegetation indices decreases in high vegetation densities, making them inappropriate for estimation of the desired parameters. Vegetation indices are saturated in alfalfa ...  Read More

Evaluation of Sentinel-2 imagery for the estimation of Silage maize biomass: A case study of Magsal Animal Husbandry & Agriculture, Qazvin, Iran

Farzaneh Hadadi; Hossain Aghighi; Ayoub Moradi

Volume 10, Issue 4 , February 2019, , Pages 99-120

  The accurate estimation of crop biomass using satellite data is one of the important challenges in environmental remote sensing. Traditionally, spectral vegetation indices (VIs) derived from spectral reflectances in red (R) and near infrared (NIR) bands have been employed to statistically estimate ...  Read More

Alfalfa yield estimation using Sentinel-2 satellite images- a case study in Magsal Agricultural and Production Company (Qazvin)

Farzaneh hadadi; Mohsen m_azadbakht; Maedeh Behifar; Hamid Salehi Shahrabi; amir moeinirad

Volume 10, Issue 3 , January 2019, , Pages 53-76

  Over the past several decades, many vegetation indices have been developed for crop yield estimation, each being sensitive to different levels of crop density and leaf area index, based on the bands and the algebraic formulas used in its design. However, the study of some perennial crops such as alfalfa, ...  Read More
