1. Introduction

In contemporary archaeological explorationsmultidisciplinary strategies are frequently pur-sued, although with varying degrees of successand often at the expense of internal coherence.The present paper stresses the need for a focus ongeo-diagnostics from an integrated archaeologi-cal, topographical and geophysical approach.

The Tilmen Höyük Archaeological Project isa joint Turco-Italian one: five campaigns havebeen carried out at this Bronze Age site in south-eastern Turkey between 2003 and 2007 (fig. 1),with a combined approach to excavation, restora-tion, landscape studies, site management andpresentation activities for public awareness. Inthe Fall of 2007 the Archaeological andEnvironmental Park of Tilmen Höyük was offi-cially opened. While emphasis has been placedalso on cultural and environmental characteriza-tion, we rely on a series of assumptions based onpresent scientific knowledge. Hereby follow thetwo main ones – for initially characterizing andthen successfully exploring and presenting anurban site: 1) accurate topographic survey, cou-pled with aerial photography, close-range pho-togrammetry, high precision geodetic referenc-

ing and an historical approach to the study ofarchitectural evidence, are fundamental tasks,leading to and accompanying large excavationareas; 2) extensive geophysical surveying is nei-ther ancillary nor preliminary to archaeologicalexcavations, but rather parallel to it, projectingthe scattered fragments of a past situation to alarger scale layout.

2. Ancient Urban Planning at Tilmen Höyükduring the Middle Bronze Age

The study of ancient urbanism is not just amatter concerning typologies of buildings or adescription of the spatial organization of a givensettlement: determining functional differences ofspace use, identifying space hierachies and socialclusters, reconstructing self-representational ide-ology as reflected in the shaping of settlementsare, on the contrary, the end goals for archaeolog-ical enquiries on urbanism1.

AN INTEGRATED APPROACH FOR THE USE OF GPS AND GPR INARCHAEOLOGICAL SITES: A CASE-STUDY AT TILMEN HÖYÜK IN SOUTH-EASTERN TURKEY

Gabriele Bitelli, Marco Bittelli, Federica Boschi, Nicolò Marchetti, Paola Rossi, LucaVittuari

Argomento del presente lavoro è la presentazione di un protocollo integrato efficace per caratterizzare le proprietà siapedologiche, sia archeologiche (che siano coerentemente integrate in una strategia di scavo e in una rete geodetica), qualeè stato sperimentato sullo scavo di un sito del Bronzo Medio in Turchia sud-orientale, a Tilmen Höyük. L’utilizzo delGround Penetrating Radar (GPR) per ottenere informazioni sulle proprietà del sottosuolo è diventata una pratica digrande interesse in campo archeologico. Il Georadar può essere affiancato da tecniche di Global Positioning Systems(GPS) per l’analisi e l’integrazione dei dati. L’utilizzo combinato di queste tecniche permette una campagna diprospezioni geofisiche più dettagliata, che include informazioni diverse e dettagliate in un unico sistema georeferenzi-ato. Gli obiettivi di questa ricerca sono quindi stati di: (a) identificare evidenze archeologiche subsuperficiali, carat-teri idrologici e pedologici utilizzando il GPR accoppiato ad un sistema GPS di alta precisione, (b) implementare unaprocedura per l’integrazione dei dati ottenuti in un sistema informativo geografico e (c) creare un modello tridimen-sionale del sottosuolo basato sulle informazioni ottenute con il GPR. I risultati ottenuti hanno permesso di creare unmodello del sottosuolo georeferenziato che permetta di interpretare la struttura del sito antico, non solo dal punto divista archeologico, ma anche idrologico e pedologico.

be approached from several points of view: forinstance, horizontal excavation exposures (andthe consequent study of the eco- and artifactsretrieved) are an effective mean to that aim2,but they must be coupled with a detailed analy-sis of the written sources3, where available, andhigh precision topographic researches (see § 3),set within a landscape perspective (see e.g.Wilkinson 1990).

The results of surface research on archaeo-logical sites must be, generally speaking, eval-uated carefully: the results of superficial scrap-ing at Çatal Höyük, for example, supplied anapparently regular architectural layout, which,when excavated, was found to represent severaldifferent chronological phases (Matthews1996). Same or similar manual operations insouthern Iraq, however, gave more coherentresults at Abu Salabikh (Postgate 1994) and atMashkan Shapir (Stone, Zimansky 2004). Themost extensive evidence has been obtainedthrough geophysic surveys at sites such asKusaklı and Kerkenes Dag in Turkey (datingrespectively to the Late Bronze and the IronAges, see Müller-Karpe 2007; Stümpel, Erkul2006; Summers, Summers 2006; 2008): allthese sites have a limited settlement history inmost areas, as it is the case at Tilmen.

At Tilmen, the excavations revealed thelayout of a Middle Bronze II (hereafter MB II)capital, 5.5 hectares large, from c. the 18th-17th centuries BC (fig. 1). The lower town hascasemate fortifications and could be enteredthrough a main city gate (K-1), besides twosmall posterns (K-2 and K-3): a sacred area(M), set on a higher ridge along a street com-ing from postern K-3, was seemingly connect-ed to the public area on the acropolis by meansof a wide roadway. Only the western lowertown had actually a significant extension, theother parts of it being only represented by nar-row strips between the city walls and theacropolis. The acropolis, fortified on threesides by casemates and fortresses, was accessedthrough a monumental stairway (K-5), fromwhere – after passing by a large residency – anoblique road led to the public area along thesouthern side of the mound to the south,where some roads met at acute angles . Thepublic compound was the most notable urbanfeature of the town, being made by threemajor buildings (E, A, H), the combined rec-tilinear southern façade of which stretches for75 m, with a presumable original height of atleast 12 m, bust most probably significantlymore (fig. 2)4.

4 For excavation reports see Marchetti 2006; 2006b;2008a; 2008b; 2008c; on the survey methods seeCerasetti et alii 2008. A Turkish expedition firstworked at the site between 1959 and 1972 (Alkım1969; Duru 2003). The constructional features of thepublic compound were, on a less grandiose scale,usual at the site during the MB II phase: the monu-mental buildings which have been explored in detailhad in fact vertical outer façades reaching the foot ofthe acropolis (residency K-5 and fortress Q) or of theglacis around the lower town (fortress P).

2 This can be achieved through the study of differenti-ated distribution patterns of material culture assem-blages within contexts. The context is the fundamen-tal unity for recovering meaningful informationabout the interconnections existing in the Pastbetween fixed and mobile artifacts, the relationshipsbetween different sets of man-made evidence(Appadurai 1986).

3 See for example Mayer 2003: 238-239 n. 2 s.v. ribītufor the existence of the ribītu, the main street of OldBabylonian towns on which abutted the main build-ings of the town. An excellent, though unfortunate-ly rare, case offered by textual studies is representedby Harris 1975. Written texts must also, though ofcourse not exclusively, be set within their retrievalcontext: however, the extraordinary potentialitiesoffered by the ancient Near East – in which an abun-dant textual documentation has been often found insitu – have not too often been exploited in detail: forexample, when extensive excavations were carriedout, such as for late Neo Babylonian levels inBabylon (Koldewey 1925), contextual informationwas mostly lacking and the archives are only recent-ly being studied (Baker 2008).

the survey works, carried out at differenttimes and scales within the Tilmen archaeo-logical site complex. This task required ashared absolute geodetic reference system(Bitelli et alii 2006b) that may guarantee max-imum flexibility to integrate a wide array ofdata coming from different prospection tech-niques on one side and to consolidate them forfuture projections to the higher dimensions ofregional studies, that require the incorporationof all landscape data in their historical projec-tion (Bitelli 2008). In particular at Tilmen thebasic operational platform was the integrationof high precision Global Positioning System,Ground Penetrating Radar and total stationsurveys, to aggregate the separate layers oflandscape aspects and artefacts in a mostdetailed contextual definition (Leick 2004;Wiseman, El-Baz 2007).

Measurements at Tilmen were carried outin 2005 by using Global Positioning Systemwith dual frequency “geodetic class” instru-ments and suitable processing software. TheWGS84 (ITRF2000) geographical coordi-nates of a master station, named ST01, were

determined by means of very long measure-ment sessions (GPS static method) to the mostadjacent GPS permanent stations belongingto the scientific network of the InternationalGeodetic Service (IGS), while for the reduc-tion of the ellipsoidal height to the orthomet-ric value the EGM96 global geoid undulationmodel was applied (Vittuari 2008).

The master station was placed on the high-est spot of the site, while some other second-ary stations were measured during the cam-paign by rapid-static method in order toestablish a network of points coherently sur-veyed and useful as reference for topographicalsurveys made by means of total stations dur-ing the excavations. Final overall elaborationwas performed in post-processing, using mostaccurate ephemeris data (fig. 3).

3.2. Digital Terrain Model Determination

The elaboration of an accurate DigitalTerrain Model (DTM) for the area is essentialfor a large number of applications in archaeol-ogy (in the context of this work, only the inte-

gration with geophysical prospecting isreviewed).

Several geomatic techniques are nowadaysavailable for DTM and DSM (Digital SurfaceModel) determination, starting from classicaltopographical surveying to spatial geodesy,from Photogrammetry to Laserscanning, andhave been largely applied by the Authors atdifferent sites (e.g. Bitelli et alii 2006a). ForTilmen, a combined total station – GPS acqui-sition was chosen, both for the accuracyrequirements and for logistic constraints.

Regarding the classical topographicalmeasurements, several points have been sur-veyed inside the site by radial measurements,performed with a total station placed at thestations mentioned in § 3.1. The samplingprocess was adapted to the local morphologicalcharacteristics, with a total amount of about3500 acquired points.

To integrate these data, a kinematic GPSsurvey was carried out (fig. 3), with a lot ofwalking in and around the site using twoinstruments (single and dual frequency), witha third instrument simultaneously acquiringat the master station; the precision of theresults, considering the intrinsic reliability ofthe method and the running positioning of the

antennas, can be estimated in the order of a fewcentimetres. Of course, GPS calculated posi-tions have been referred to the orthometricheights as described in § 3.1.

Starting from these data, several numericalmodels of the terrain were calculated using thegeostatistic kriging approach, with differentcell sizes starting from 1 m. In fig. 4 an exam-ple is shown, with cell size of one meter andshaded relief representation.

3.3. GPR prospecting georeferentiation

Accurate GPS surveys were also applied forgeoreferencing the transects performed forgeophysical prospecting. In this case doublekinematic determination of the stakes wasapplied, surveying the same stake twice, dur-ing different walks, and evaluating the accura-cy by the two calculated coordinates sets(heights referred to the m.s.l.). The results ofthis assessment guaranteed that accuracy andprecision were in optimal agreement with therequirements (at centimetre level in relativeand a few centimetres in absolute).

(G.B., L.V.)

4. The use of GPR for soil and archaeologicalsurveys5

4.1. GPR Survey

A detailed GPR campaign was performed atthe site using two types of instrumentation: aGSSI (Geophysical Survey System Inc., USA)SIR-3000 with an antenna operating at 200MHz and a RAMAC (Ramac Inc., Sweden)with an antenna operating at 250 MHz.

The measurements were performed overgrids of 0.5 x 0.5 meters, with meanderingacquisition in both North-South and East-Westdirections, georeferenced by means of the GPSsurvey described in § 3.3. Various areas have

been surveyed as shown in fig. 1, where the let-ters identify the different surveyed areas.

The soil moisture conditions at the time ofthe survey were very dry (measured soil moisturewas at an average value over the entire area, of0.15 m3 m-3), thus facilitating the survey becauseof the overall low dielectric permittivity of thesoil. Several transects were repeated many times,by testing different system setups (such as wavevelocities, signal amplification and trace num-bers) to identify the best setup for the survey. Thedense surface scattering of basalt stones limitedthe extension of surveyed areas.

4.2. GPR Data Processing, Analysis andInterpretation

Data processing was performed using the soft-ware GPR Process, which provided time slicesthat are a bi-dimensional representation of thereflected signal amplitude at different depths6.

Maps of the buried features were created byusing various time slices. The maps, which maybe subsequently used for an archaeologicalinterpretation, represent the signal amplitudesrecorded by the GPR. A chromatic scale hasbeen used, with blue indicating low amplitudesand red representing high amplitudes. A vari-ety of maps were created to perform a detailedinterpretation of buried features. Identified fea-tures were then confirmed by analyzing the cor-responding original B-scan trace. Finally, inter-pretation was written on each time slice for itsrepresentation on geo-referenced maps.

All surveyed sectors (see fig. 1 sub a-g) dis-played significant differences in the dielectricproperties of the material both in the horizon-tal and vertical directions. Vertical dielectriccontrast occurs mostly at a depth comprisedbetween 30 and 90 cm. In some cases, the pres-ence of deeper features was also detected. Theslice map corresponding to sector “b” (fig. 5b)

generated an image where parallel walls definetwo square rooms, with additional structures onboth sides. The vertical GPR traces (B-scan)confirmed the presence of walls and otherarchaeological evidences. It is worth noting thatthe buried features reveal similar proportionsand the same topographical orientation (45 to60 degrees to the North, and parallel to the lineof the northern casemates excavated nearby).These architectural characteristics suggest thatthe buried features belong to the same period asthe casemates, i.e. to MB II.

Sectors from “a” to “e” display the presenceof archaeological features, although interpolat-ed traces are not as clear as for sector “b”. Thismay be due to superficial basalt bedrock, whichis also responsible for some dielectric anomalies(such as in “c” and “d”). In sector “e” (fig. 6) itis possible to identify a small rectangular build-ing with most likely an outer floor in theSouth-West corner of the grid (the red feature

visible in the map), all elements similar to thoseexcavated in nearby Area L. In sector “a”, thereare at least three structures which were identi-fied by the GPR survey; the feature in theNorth-East corner complements a Late BronzeAge (hereafter LBA) structure revealed in theexcavations of Area L. In sectors “f” and “g”, theGPR survey identified various floors at a depthcomprised between 30 and 60 cm, while atdeeper levels there are probably walls and otherstructures. Within sector “f”, a test excavationduring the 2006 campaign (fig. 5a) confirmedthe existence of a corresponding earlier floor(dating from MB I) at the depth indicated bythe GPR survey.

Thus, in the lower town, where only MB IIand LB I layers are attested to, but where super-ficial bedrock sometime limits GPR interpreta-tion, some structures have been identified alongthe street ascending from postern K-3 to tem-ple M, as well as along the northern casemates,

here with the possibility of “seeing” also a fewinstallations. In the northern sector of theacropolis, on both sides of Building L, twoother isolated rectangular buildings similar tothe former have been detected7, thus giving animpression of a regular line of buildings sepa-rated from the casemates by a lozenge-shapedempty space, as proven also in a trench excavat-ed between Building L and the casemates to theNorth, in which a continuous MB II pavedouter surface had previously been exposed.

An additional GPR analysis was performedto measure the water table depth in severalareas of the site, for mapping subsurface hydrol-ogy. The study was part of a more general envi-ronmental assessment of the archaeological sitefor conservation purposes and for the develop-ment of an archaeological park (see Rossi Pisa etalii 2008).

(M.B., F.B., P.R.)

5. Conclusions

The understanding of an ancient urban set-ting cannot be accomplished today without nondestructive surveys integrated through a rigor-ous methodology. Geodetic infrastructures cre-ated in the last few decades allow for the adop-tion of an international reference frame forapplications that require a precise informationgeoreferencing. The obvious contrast of themore limited use of GPR in respect of the moreextensive one of the geomagnetic method, canbe used to the advantage of a stratigraphic, i.e.vertical, approach, as well as for soil informa-tion. Significant results for the study andunderstanding of the early second millenniumBC urbanism at Tilmen have been obtained: infact, the reliability of detailed urban informa-tion supplied by geophysic surveys in archaeol-ogy becomes greater when the archaeology of agiven settlement is already familiar. In this per-spective, geophysics represent a complement to

the excavations and not just a method for guid-ing in the selection of excavation areas.
