Aljosa ZERJAL / Tina ZERJAL / Natasa KOLEGA (Harpha sea, Koper, Slovenia) Abstract:After finishing a 3D city model of the present historic town of Koper (Slovenia) using topographic and LIDAR data, as well as photographic material, the 3D/GIS team at Harpha sea d.o.o. has taken up the challenge of eventually building a 4D city model (the first phase is only the 3D historical model).The town of Koper has grown on an island near north-Adriatic coast. A larger settlement developed from Late Roman period onwards and in 13th century, under the rule of Serenissima (Venice), the island was already almost entirely covered with buildings and enclosed by city walls. The sight of the town has remained mainly unaltered till the 19th century. Only after the 1950s, its insular character has vanished, since it became part of the mainland. The goal of the project was to visualize the towns historic appearance, particularly its insular character, as a 3D model. The map of Franziscean cadastre from year 1819 (scale 1:1440) was chosen as the basis for the model. It reproduces exactly all the ground plans of the buildings, streets, squares, yards, gardens, piers and the coastline at that time, and even the course of the city walls, gates and towers, which were still standing but not in use anymore. The heights of the buildings were reconstructed from written sources of the Franziscean cadastre, observations and scientific data on standing architecture, old depictions and from photographs taken in the beginning and first half of the 20th century. 15 % of building models were more accurately modeled with attached rectified photographs of facades. The 3D city model of Koper is modeled with customized open source toolkit OpenSceneGraph (OSG), based on data stored in a PostGis database. The model can be viewed in a customized version of OSG Viewer (part of OSG) developed by our company. The 3D city model of Koper is intended to be used for pedagogical activities in cultural heritage education and cultural tourism. Keywords: 3D model, city, history, cultural...

Rafa? ZAP?ATA (Cardinal Stefan Wyszynski University, Warsaw, Poland) Abstract: The use of  laser scanning – LIDAR (Light Detection and Ranging) in archaeological research has its tradition, particularly in relation to woodland, as well as to hard-to-reach and open areas. The aim of the presentation is an attempt to discuss the application of LIDAR in archeology in relation to open areas, especially urban areas – selected examples from Poland. Poster is the presentation of the results of using the LIDAR and the possibility of using this technology in resaearch and protection of archaeological heritage. Application of the LIDAR in archaeology includes: identification of archaeological and historical objects, review and conservation status, as well as digital documentation of archaeological and historical objects. Tha basis of research are measurements and data which are obtained by MGGP Aero from Poland. Indirect aim of this research is an attempt to enable airborn laser scanning for research and protection of archaeological heritage in Poland. Keywords: LIDAR, archaeology, towns and urban areas,...

Colin WAGNER / Rachel YOUNG (Drexel University, Philadelphia, USA) Abstract: This poster will explain and illustrate the process of producing historically accurate 3D digital models of Colonial and Federalist era American window, door and molding types used in Philadelphia house and building construction.  The models were produced from architectural artifacts in the collection of the Independence National Historical Park, Philadelphia, USA.  The 3D digital models were produced in association with Karie Diethorn, Chief Curator and Charles Tonetti, Chief Historical Architect of the National Park Service. Chris Redmann and Glen Muschio served as project advisers.   The project was conducted under the auspices of “3D Colonial Philadelphia” a long range project, which seeks to create a 3D virtual environment for studying and exploring matters of cultural heritage and by Drexel University’s Students Tracking Advanced Research (STAR) Program. The locations of many Colonial and Federalists period buildings in Philadelphia are well documented in historical insurance and tax records and on city maps. Starting in the mid 19th century, some structures have been photographed before being razed.  Furthermore, foundations of a few structures have been documented and studied during various archaeological excavations.  Based on these historical records, “3D Colonial Philadelphia” intends to model entire Colonial and Federalist period street scenes.  The idea behind our project is to create a library of historically accurate architectural features, which will be used to reduce the time needed to model and render street scenes. While we may not know the window and door types for any specific house our models will be historically accurate for the period and house type. The 3D digital models will also be made available to other researchers and the general public through the Independence National Historical Park Archive. We anticipate that the virtual collection will greatly facilitate access to this valuable architectural information. Keywords: Colonial American 3D Virtual...

E. TEKDAL-EMNIYETI1,2 / K.-H. HAEFELE2 / J. ISELE2 (1Istanbul Technical University, Turkey / 2Karlsruhe Institute of Technology, Germany)     Abstract: In this poster, the laser scanning task carried out for the documentation and restoration of the Seddülbahir Fortress which is located at the Gallipoli peninsula of Turkey will be explained. The Seddülbahir Fortress project started as a research project in 1997, in 2004 the project evolved from being a research project into a restoration project. As a part of the Seddülbahir Fortress Site Documentation and Restoration Project the entire site was scanned with a point spacing of 5 mm using a Leica HDS 3000 laser scanner accompanied with a Leica TCR407 Power reflectorless Total Station. With the 360° horizontal and 270° vertical field-of-view of the Leica HDS 3000 laser scanner the survey was concluded with satisfactory results at a site comprising nearly 24.000 m2 and a building mass of 4200 m2.The scans were then processed and the point clouds were registered using the Cyclone Register program and after the registration the noises are eliminated from the data. Then the evaluation of the point cloud data is carried out. The aim of the work is to create a semantic 3D model for parts of the fortress from the laser scanning data. As possible models the international standart for building information models IFC (buildingSMART) and the international standart for 3D city models CityGML (Open Geospatial Consortium) will be evaluated. The final semantic 3D model will be used by different groups of interest (architects, archeologists, structural engineers, etc.) within multiple applications not only for visualization but also: -Examining the structural condition – As built documentation for restoration and renovation projects -As base data for 4D modelling. Our utmost thanks to all members of Seddulbahir Fortresses project team known as KALETAKIMI and especially to the both project leaders Assoc.

Gabriel SEIDL / Silvia MÜLLER / Richard THOMA (AS-Archäologie Service, Krems, Austria) Abstract: 3D laser scanning is a fresh approach on describing archaeological, architectural and historical art objects. AS – Archäologie Service has used and refined this procedure for several years to survey and illustrate diverse artefacts. Working with a high degree of precision this method is able to preserve the accurate structure of surfaces. Further evaluation leads to exact virtual models in three-dimensional space. This true-to-surface model is highly recommended for object description, virtual documentation and digital archiving. It is a big step towards holistic documentation.The collected data is a first-class base to expose and to publish artefacts or even for reconstruction. AS – Archäologie Service offers affordable access to a 3D laser scanning facility and provides adaptable post processing for all purposes. Keywords: 3d close range laser...

Ute SCHOLZ / Silvia MÜLLER / Richard THOMA (AS-Archäologie Service, Krems, Austria) Abstract: AS-Archäologie Service carried out an excavation in Schwechat, Lower Austria in 2010. Two barracks constructions of the ancient Roman military camp for cavalry troops “Ala Nova” were almost fully excavated. Three Roman construction phases were detected, beginning with wooden buildings from the first century AD. In the second phase (2nd, 3rd century AD.) a castle was built there with stone basement in opus spicatum. Accommodation contains the so-called “head building”, soldiers’ rooms and aside located stable rooms with dumping pits for horse urine. The building was completed with a wooden porticus. In the third phase (3rd, 4th century AD.) the camp was rebuilt, shown by adobe floors and wooden constructions. Some rooms were added to the remaining walls in the 4th and 5th centuries AD, other rooms with different orientation were additionally built. At least two buildings were erected above the Roman constructions in the 6th and 7th centuries. This is the first proof of Avar colonization inside of a roman camp in Austria. From then, brisk settlement could not be proved until the 17th century AD. Many findings of the respective eras were brought out, among three Roman crossbow fibulae, a plate fibula, several coins, three Roman lanceheads,  fittings of horse harnesses, thereof one with animal depiction, a bone dice and a brick with a stamp of the 10th legion on it. From the Avar era came the usual pottery and a buckle which was used as a fibula in the late Roman era, among tools made of animal bones. Keywords: Roman military camp,...
