Efficiency of vegetation and thermal indices of NOAA-AVHRR satellite in ecological drought analysis of Kashan region

Ali akbar Shamsi pur; Kazem Alavi panah; Hossein Mohammadi

Volume 17, Issue 3 , October 2010, , Pages 445-465

Abstract
  The purpose of this study is to track and analyze the environmental effects of droughts by remote sensing indices in Kashan desert and dry zone. Temporal changes of droughts was evaluated using normal Z index in annual and seaonal (spring) scales. Spectral and thermal data from data series of NOAA-AVHRR ...  Read More

Remotely sensed data evaluation on soil spectral properties in arid regions

Hamid reza Matin far; Kazem Alavi panah; Ammar Rafiei Emam

Volume 16, Issue 4 , January 2010, , Pages 560-573

Abstract
  One of the apparent characteristics of soil is color which shows high correlation with soil characteristics and spectral reflectance. Soil color is identified using visual comparison of sample and colored chips of Munsell color charts .In arid regions due to the prolonged sunny days, low soil moisture, ...  Read More

Study of various soils spectral variability using remotely sensed imagery "Case study: Varamin region"

Ammar Rafiei Emam; Kazem Alavi panah

Volume 13, Issue 1 , February 2006, , Pages 1-9

Abstract
  Remote sensing plays a considerable role on detection of natural resources features by its multi spectral means. Three decades works of remote sensing scientists have resulted in presentation of several vegetation indices, for soil how ever there are not many examples. TM spectral ratioing have been ...  Read More
