J Sadidi; P Zeaiean Firozabadi; Z Darvari

Volume 9, Issue 3 , February 2018, Pages 15-32

Abstract
  Today, one of the limitations of water resources is the solutions weakness of water resource management. One of the management solutions to improve the problem above is the optimal allocation of users with the virtual water approach. In the present study, a model for optimization of user allocation with ...  Read More

Fusion of MODIS and OLI Images for Estimating Daily Surface Reflectance at 30m Spatial Resolution in Complex Heterogeneous Regions

M Rahimpour; N Karimi; R Rouzbahani; A Rezae

Volume 9, Issue 3 , February 2018, Pages 71-90

Abstract
  Cocurrent access to high spatial and temporal resolution imageries is essential in many studies. However, this will not be provided by using images from one sensor. To achive this goal, the incorporation of different satellites with high spatial (e.g., Landsat) and temporal (e.g., MODIS) images can be ...  Read More

A Smart Location Model, Based on Multi-Objective Genetic Algorithms to Find Optimal Routes in the Road Network

A Matkan; B Mirbagheri; K Akbari

Volume 9, Issue 3 , February 2018, Pages 111-126

Abstract
  Finding optimal Paths between two points on the Road network is one of the most spatial analysis in GIS. The high diversity of possible Paths between two points and difficult in apply all parameters simultaneously select the optimal Path (length of Path, easily track, traffic, road quality…) make finding ...  Read More
