eastern atlas - Archaeogeophysical Prospection

Archaeogeophysical Prospection
Our range of services includes: • complete planning and technical preparation of prospection projects, • technical implementation of non-destructive geophysical investigations, • aerial photography and topographical field survey • state-of-the-art data processing and expert interpretation. METHODOLOGICAL VARIETY eastern atlas is a leading specialist and a certified geophysical prospection company (BDG) that offers the whole spectrum of geophysical investigation methods and a broad experience in the archaeo-geophysical prospection on four continents. Archaeological tasks are handled using the best suitable method or combination of methods. They range from fast DGPS-supported magnetic prospection for large areas to detailed 3D exploration of complex underground structures or existing buildings in urban archaeology. You will find an overview of the different methodologies under TECHNOLOGY. To get information about selected research projects and results, please see PROJECTS. Examples of the application of archaeogeophysical investigation methods on different sites and periods, see below: SUB-DISCIPLINES From Neolithic to Iron Age Classical Archaeology Near Eastern Archaeology Roman Archaeology Medieval Archaeology Contemporary Archaeology Historic Preservation

FROM NEOLITHIC TO IRON AGE AERIAL PHOTOS - GEOMAGNETICS - EXCAVATION Aerial photos and field surveys often provide first hints to archaeological structures in the ground. Subsequent application of geophysical methods, mostly geomagnetic mapping, result in maps displaying the exact ground plans, enclosures, pit alignments or burials. Hence, geophysical data allows to plan and execute purposeful and efficient excavations without disturbing the sites.

CLASSICAL ARCHAEOLOGY TOWN AND HOUSE IN 3D Pompeii's ruins open a fascinating insight into a typical Roman town of the 1st century AD. However, its urban development in the centuries before remains less clear. Urgent preservation needs and excavation bans - Pompeii is a prominent example among other antique sites in a similar situation. Therefore recent research projects focus on non-destructive investigation primarily on detailed 3D imaging methods as the base for virtual reconstructions.

NEAR EASTERN ARCHAEOLOGYTHE FERTILE CRESCENT Tells (From Hebrew: תֵּל‎, tel or tall in Arabic: تلّ‎, tall) are the characteristical archaeological monuments of the Near East. They mainly shape the typical landscapes between the Bosporus and the Shatt al-Arab. Tells emerge from the accumulation of settlement materials over centuries or even millenia. Their conservational investigation requires a combination of geophysical methods, topographical surveys and archaeological knowledge. Terrain model and geomagnetic data of Tell Djinderis (Syria)
ROMAN ARCHAEOLOGY ON THE EDGES OF THE ROMAN WORLD Roman engineering and architecture have left countless and impressive monuments between Northern Africa, Britain and Asia Minor: Roman baths in Africa Proconsularis, qanats in Germania Superior up to 20 meters deep and mining centres in Baetica. Geophysical methods help to discover and investigate the relics - quickly and non-destructively.

MEDIEVAL ARCHEOLOGYCASTLES, MONASTERIES AND VILLAGES The application of geophysical prospection methods in the field of medieval archaeology involves the investigation of abandoned settlements and fortifications as well as the architectural survey of still existing constructions. The prospection of castles and monasteries is most promising when tomographical methods like GPR and geoelectrics are combined. This allows not only the localization of walls and foundations but also the detection of ditches, pits and wells. In the case of undeveloped areas high-resolving geomagnetic measurements are recommendable. Magnetogram of remains of a motte-and-bailey in Central Germany

CONTEMPORARY ARCHAELOGY THE RECENT PAST Vestiges of monuments of the recent past often come along with modern perturbations. Profound experience and a broadly diversified methodology ensure successful prospection results. Even historic excavations can be located and delimited from genuine archaeological features.

HISTORIC PRESERVATION NONINVASIVE INVESTIGATION Non-destructive testing like high-frequency GPR and microelectrical prospection permit a cautious investigation of existing buildings even when in danger of collapse. Further fields of application of geophysical methods are the exploration of non-accessible areas, like fault investigation under pavements, the determination of material properties and the investigation of foundations.
