Abstract

In the recent past, archaeologists used in their study traditional methods. Now, remote sensors have become essential equipment in archaeology studies, either used on board satellites in space or on airborne. Producing modern maps for the archaeological sites is very essential for develop and protect it. The Orientation of ancient Egyptians constructions is still surprising among astronomers and scholars in the world to find out how ancient Egyptians oriented the axis of their constructions with high accuracy. Main research objective is using remote sensing data and techniques to assess producing image map and to determine the direction of the axis of Heritage site. The Mortuary Temple of King Ramses III at Habo Luxor, Egypt has been selected as study area. The study area covered with QuickBird 0.6m resolution slandered pansharped images. A coarse digital elevation model DEM has been used release the topographic relief. Also, ground control points GCPs and check points CPs have been used for geometric correction and image map accuracy assessment. The proposed methodology involves many steps included geometric correction of QuickBird satellite imagery using an appropriate mathematical model and asses the scale of the produced image map. After that, the direction of the main axis of the heritage site has been determined. A comparative study has been performed between traditional method based on direct GPS measurements and the suggested method. The obtained results of the study showed that the accuracy of the produced image map using second order polynomial function gives TRMS 4.288m which satisfies theoretical large scale mapping of 1: 10 000. The difference between axis direction of the temple from the produced image and from GPS direct measurements was ± 0 deg 59 min 7 sec.

Summary

Introduction

The use of remote sensing technology offers the archeologist the opportunity to detect these impacts. Astronomical orientation of temples not easy to study because it needs the right constructions dates to check them out. David Furlong studied the direction of the axis of Egyptian temples using satellite imagery which available free in Google Earth (David Furlong, 2007). Temples Karnak, Luxor, and Hatshepsut at Thebes using satellite imagery which available free in Google Earth without doing any geometric correction (Amanda-Alice Maravelia and Muslim Shaltout, 2010). Shaltout and Ramzi Method used QuickBird 0.6 m resolution pansharped slandered images which radiometric and geometric corrected by venders without using any additional ground control points GCPs and check points CPs (Shaltout and Ramzi, 2012). There are generally two types of mathematical models used to correct the distortions of satellite imagery: physical models and non-physical models. In this research geometric correction of satellite image using different number and distribution of GCPs will be carried out image rectification using digital elevation model (DEM) will be carried
