Assessing Thematic Map Using Sampling Technique

The estimation of accuracy of thematic maps derived from remotely sensed data used in conjunction with a geographic information system is presented. A systematic random sampling techique is proposed to asses the accuracy. The main objective of this work is the determination of the optimal sampling intensity and the appropriate sample size used to assess the accuracy. The data set used is a Land...

Modelling Topographic Potential for Erosion and Deposition Using GIS

Modeling of erosion and deposition in complex terrain within a geographic information system (GIS) requires a high resolution digital elevation model (DEM), reliable estimation of topographic parameters, and formulation of erosion models adequate for digital representation of spatially distributed parameters. Regularized spline with tension was integrated within a GIS for computation of DEMs an...

Determining the structure and map of vegetation of Mirabad protected area (Iran) using DEM and Geographic Information Systems (GIS)

The Mirabad protected area (S. Azarbaijan, Iran) has a variety of ecological nurseries due to elevation of the sea, physiographic factors, micro-climates and soil types, and has high vegetation diversity. Mirabad protected area in the Piranshahr-Sardasht axis is between the latitudes of 36° 23' and 36° 31' north, and the lengths 45° 15' and 45° 25', with an area of ​​11435 ha, in the elevation ...
