ABSTRACT

Both geophysical and geospatial data provide important information in the establishment

of the optimal telecommunicat ion systems especially in the mobile telecommunication

environment. The objective of this study is to utilize geophysical properties and geospatial

information in the analysis of the telecommunication environment through point- to-point

wave property modeling. Geophysical properties associated with wave propagation

parameters of the earth surface were analyzed based on hierarchical land classification

using Landsat ETM+ and IKONOS images. Three- dimensional geospatial information was

obtained by processing stereo aerial images. The results show that the accurate geospatial

information and reliable geosphysical property of the surface improve the prediction of

receiving power of the receivers located near corners of the buildings where diffractions

occur. The wave property model developed from accurate telecommunication environment

could be applied to optimal cell planning and delay time analysis.
