Visibility Analysis in Archaeology Using Digital Elevation Model Produced from SRTM

Abstract

A visibility analysis was performed with ERDAS Imagine Ver. 9.2, using Digital Elevation Model (DEM) produced from SRTM. Digital elevation models (DEMs) were already widely used and play an increasing important role in geomorphology, hydrology, soil erosion and many related geo-analysis fields. Visibility analysis did not really become popular in archaeology until the late of 1980's. There were a number of ways that visibility analysis could be applied to archaeological problems. Frequently archaeologists were concerned with whether one site was visible from another site. View shed depends on the height of the viewing point. The alteration of this height brings alteration of the view shed.
