Ant Colony Optimization of RFM for Geometric Correction

A Baghani; M.J Valadan Zoej; M Mokhtarzade

Volume 7, Issue 2 , November 2015, Pages 1-18

Abstract
  Due to the absence of either satellite ephemeris information or camera model for various high resolution satellite images, rational functions models (RFMs) are widely used by photogrammetric and remote sensing communities. This method has various disadvantages such as: The dependency of this method on ...  Read More

The Effect of Atmospheric Moisture on the Estimation of the Temperature Inversion Characteristics from MODIS Images

H Kachar; M.R Mobasheri; A.A Abkar; M Rahimzadegan

Volume 7, Issue 2 , November 2015, Pages 35-53

Abstract
  Increase of temperature with height in the troposphere is called temperature inversion. Parameters such as strength and depth are characteristics of temperature inversion. Inversion strength is defined as the temperature difference between the surface and the top of the inversion and the depth of inversion ...  Read More

Evaluation of Different Parametric Situations on Satellite SEBAL, METRIC and TVT Methods on Estimation of Actual Evapotranspiration in the Northern Ahwaz Study Region

H Taji

Volume 7, Issue 2 , November 2015, Pages 89-106

Abstract
  Remote sensing (RS) data is widely applied for estimation of actual evapotranspiration (ETa) and different methods are also developed in this regard. Among them, SEBAL and METRIC as energy balance models and TVT as vegetation-based have received more attentions. However, they are based on some parameters ...  Read More

A GIS-based Assessment of Drinking Quality of Lordegan Plain Groundwater using a GWQI Index

Y Ostovari; H Beigi-Harchegani; S Heshmati

Volume 7, Issue 2 , November 2015, Pages 107-120

Abstract
  Groundwater quality index (GWQI) is a one of important index to assessment of groundwater quality. The aim of this study was to assess the drinking quality of Lordegan aquifer using a GWQI (groundwater quality index) within a GIS framework. To do this, 97 wells were sampled and pH, Electrical Conductance ...  Read More
