K. Jain Center of Remote Sensing & GIS, School of Studies in Earth Science, Jiwaji University, Gwalior (M.P.) - 474011, India, (dpkj_2005@yahoo.co.in) ----------------------------------------------------------------------------------------------------------------------------- -------------------------------- ABSTRACT: Many geoarchaeological monuments / sites are developed in and around the Gwalior fort, famous of them are Manmandir Palace, Vikram Mandir, Karan Mahal, Johar Kund, Bhim Kund, Sas-Bahu Ka Mandir, Suraj Kund, Teli Ka Mandir, Urwahi Group, Trishala Giri, Ek Pathar Ki Bawari, Gujari Mahal, Girnar and Siddhanchal. Some of them are present over the surface and few within the Kaimur formation of Vindhyan Super Group. Lithological all are made by the same sandstone material, as derived from the in situ geological formation. Geoarchaeology is the multidisciplinary recent approach of research, which integrates geographical, geological and archaeological information about the sites, which are present over and under the earth surface for investigations with the help of computer. Global positions of the said sites are recorded first time by using the modern technology of the recent high-tech world. GPS (Global Positioning System) is a satellite based navigation system, which provides exact location of any site present on the earth surface, in the form of geographic coordinates (latitude and longitude) with elevation (height) from MSL. On the basis of Cartesian coordinates, the global position of the said geoarchaeological sites can be shown on the world globe. More over the same data can be manipulated by GIS (Geographic Information System) for making a site map as per our choice. Remote sensing provides the RSD to get the required information within, in the remote sensing community; the GPS has been recognized as an accurate, fast and cost effecting method for collecting the geographic coordinates, which can be used in surveying and GIS applications. Normally it takes month or more by using conventional methods, beside by using RSD, GPS and GIS techniques, the work can be done in few days. KEYWORDS: Geoarchaeological Sites, Remotely Sensed Data (RSD), GPS and GIS. ----------------------------------------------------------------------------------------------------------------------------- -------------------------------- 1. INTRODUCTION: The Gwalior fort (Fig.I) is equally world famous like the ancient Gwalior city in the Indian history. Almost N-S trending fort is situated in middle of the city, resting over the 288 feet thick hill (1), known as fort hill,and covering approximate 5 sq. km. area, falls in SOI toposheet no. 54 J/4. Fig. I: Location Map Many archaeological monuments / sites are well developed in and around the fort; famous of them are namely- Manmandir Palace, Vikram Mandir, Karan Mahal, Johar Kund, Bhim Kund, Sas-Bahu Ka Mandir, Suraj 2 Jain, P. K/Geospatial Science, Vol.1, No. 1 Kund, Teli Ka Mandir, Urwahi Group, Trishala Giri, Ek Pathar Ki Bawari, Gujari Mahal, Girnar and Siddhanchal. Archaeological study deals with ancient history from the surviving traces of former societies (2). On other hands, geoarchaeological techniques explore and examine the materials of the sites without conducting the major excavation on the site (3). Geoarchaelogy is a recent field of research that uses the computer, cartography, GIS and DEM in combination with disciplines from human and social sciences and earth sciences (4). The global positions of the said sites are recorded for the first time by the “GPS receiver”. 2. MATERIALS AND METHODOLOGY: 2.1. REMOTELY SENSED DATA (RSD): Remote sensing is a tool or technique by which we can get the information about any object present over the earth surface, without going and touching the object through the analysis of the RSD, which are acquired by a device from a space or air-born platform. Archaeology is concerned with the scientific study of historic or prehistoric peoples by analysis of the remains of their existence, especially those remains that have been discovered through earth excavation (5). RSD are used here to identify and locate the sites under investigations. Satellite image of IRS 1D, L 3, Geo-coded, Map ID 54 J/4, scale 1:50,000 is used. 2.2. GLOBAL POSITIONING SYSTEM (GPS): GPS is a satellite based navigation system. It is based on the principle of trilateration. Trilateration is the basic geometric principle (6) that allows finding a location of the objects under investigation. When we make a ground observation, we would like to get its accurate location on the earth globe (7). GPS provides the exact location in the form of X, Y and Z, i.e. latitude, longitude and altitude (height) of any ground object. In the sphere, satellite data could be effectively used for mapping archaeological monuments. The Hampi remains were mapped in a similar way (8).“Garmin” make, etrex vista HCx model GPS receiver is used (Fig. II) to get the geographic location with altitude of the investigated site to locate them globally. Fig. II: GPS Receiver 2.3. SURVEY OF INDIA (SOI) TOPOGRAPHIC MAP: It is used as a base map of the study area, because which contains all basic information regarding the terrain elements (9) of the investigated site. SOI toposheet no. 54 J/4 is used to correlate the investigated site locations in the satellite image of same area. 2.4. GEOGRAPHIC INFORMATION SYSTEM (GIS): GIS is a computer based system, consists by hardware and software, which provides the location details to solve the problem “what is it”? (10) on the globe, moreover manage and analyses large volume of spatially referenced data associated attributes from a variety of sources (11). It has effectively revolutionized the way in which disciplines such as geography, land resource management, ecology and archaeology handle and interpret spatially referenced data sets of the earth’s surface (12). GIS means of manipulating, multivariate complex observations within relatively flexible computer environment. Arc GIS software is used to prepare a global map of the Gwalior fort, to show the geographic locations of the geoarchaeological monuments within. 3. GLOBAL LOCATION OF THE GWALIOR FORT: Global location of the famous Gwalior fort (encircled) is shown in satellite image and SOI topographic map of same scale in Fig. III, the fort lies in between the Cartesian coordinates 26012’35’’ to 26014’06’’ N and 78009’45’’ to 78010’32’’ E (13) and the fort hill section comprises with 86 m thick rock pile from ground level (GL) i.e. 220 m from MSL. It is situated in NW direction, approximately at the middle of the Gwalior city. 3 Jain, P. K/Geospatial Science, Vol.1, No. 1 (a) (b) Fig. III: Location of Gwalior Fort (encircled) in Satellite Image (a) and SOI Map (b) 4. GEOLOGY OF THE AREA: Geologically, the area under investigation is developed in Sandstone of Kaimur formation (Upper Vindhyan Supper Group). Gwalior fort is rest on Kaimur formation. Jain colossi namelyUrwahi group, Trishla Giri, Ek Pathar Ki Bawari, Girnar and Siddanchal are excavated within (Fig.IV) the sandstone of Kaimur formation. Rest monuments are made by the in situ geological material and locate on the surface within the boundary of Gwalior fort. Geological setup (14) of the study area is shown in table I. Physical and megascopic characters of the construction material of all the investigated sites suggest that, they were formed by the same material as available around the fort. Moreover, some monuments / Jain colossi are architected within the said geological formation by excavation and rest are on the formation by masonry work. In general, the sandstone of the Kaimur formation shows fine grained and soft in nature, that’s why any design can be developed within as well as external form of the monuments with the same. Surrounding conditions of the investigated sites are itself stated the story regarding their in situ construction material without any doubt. Vertical lithological succession at the Gwalior fort hill section is also shown by the Fig.IV.

CONCLUSIONS: Geoarchaeological techniques are used frequently by the researchers in present time, to explore hidden sites and examine buried artifacts without conducting a major excavation and remote sensing offers more sophisticated options to the geoarchaeologist for find out unexplored hidden sites, one major goal of this process Jain, P. K/Geospatial Science, Vol.1, No. 1 8 is exploring landscape histories of a specific region. The study suggests that, all the geoarchaeological sites are made by same in situ material as derived from the Kaimur formation of Vidhyan Super Group. Lithological, monuments /sites are formed by the Kaimur sandstone. The GPS technology has been recognized as an accurate, fast and cost effecting method for collecting the geographic coordinates in terms of X, Y and Z i.e. Latitude, Longitude and Altitude. The records / data (X, Y and Z) can be used well in surveying to generate the map of the area under investigation. Geographic coordinates are well known parameters to solve the problems related to the location of the objects in the “World Globe”, subjected to where is it? And what is it? By use of GPS, the work can be done within few hours or a day instead of month or more. It is a time and money saving technique. Remote sensing provides us the data (RSD) for analysis and identifying the objects in the same, GPS confirms their locations in the field. Moreover, the data can be manipulated and integrated as per our choice by use of GIS. ACKNOWLEDGEMENTS: Author is highly indebted to express their hearty thanks to Dr. S. N.
