Virtual Meridian Augustus

John FILLWALK, IDIA Lab: Institute for Digital Intermedia Arts. Ball State University, Muncie, USABernard FRISCHER, Department of Informatics, Indiana University, USA Keywords: virtual reality, augmented reality, celestial alignment, ancient Rome Abstract:Pontifical Academy of ArcheologyWith generous support from the National Science Foundation (grant # IIS-1014956), we have recently been developing a digital simulation of the northern Campus Martius in the period 9 BCE to 40 CE. [1] Our motivation is to create a tool that makes it possible instantly to see the correct positions of the sun and its shadow at any time of day in this period of time so that the various controversies associated with the work of Edmund Buchner on the so-called “Horologium Augusti” can be approached in a new way. Of course, precision and valid results always depend on the reliability of the data represented in a simulation. For the all-important apparent size[2] and position of the sun in the sky dome of the simulation, we have relied on NASA’s Horizons System. Among other things, this database takes into account the changes in the sun’s apparent course through the sky that arise from the earth’s wobble as it rotates, providing correct azimuthal information for any point on earth in any historical period, including the Augustan age.

Dimitar FILIPOV, Independent, Sofia, Bulgaria Keywords: photo, history, comparison, digitalisation Abstract:Parallel is an innovative mobile application providing the user with visuals and description of different city sightseeings along with their location on the map and their appearance before and after. Nowadays local and international tourists have limited possibilities when it comes to observing a certain sight as they can only see its current appearance. Parallel gives the user the opportunity to witness the development of different landmarks as it shows them their current look as well as a historical one, captured in a photo, alongside with a brief history description. Partnership with different parties like historians, architects and experts will develop a solid information base attached to every picture translated in different languages. Furthermore, local museums and galleries will contribute to the experience by providing insights of the certain sightseeings. Additionally, a global map with the location of the sightseeings will navigate the users through their adventure encouraging them to step out of their comfort zone and explore the environment around them. While being able to explore every single photo comparison, even while not being directly next to it, we have added an achievement system to promote the actual trip to a site, giving achievements based on the geographic location of a user to a given...

Heritage-BIM between Survey, Planning and Management

Piotr KUROCZYNSKI1 | Claudiu SILVESTRU2 | ( 1Hochschule Mainz – University of Applied Sciences, Germany | 2hochform. Architekten ZT GmbH, Austria) Keywords: Historic/Heritage BIM, 3d modeling, 3d reconstruction, data management. Building Information Modelling (BIM) is the answer of contemporary building industry to improve the collaboration of all specialist engaged in the planning, construction and facility management process. BIM as the collaborative methodology to plan and manage crucial information is based on the data exchange format Industry Foundation Classes (IFC),. As ISO 16739:2016 IFC ensures the sustainability and interoperability of the object-based information. The growing interest in the cultural heritage – recognized as being crucial as well for the local identity as for economic development of the regions – increases the projects concerning the protection, conservation, restoration, and dissemination of cultural heritage. The instrumentalization of BIM/IFC for this kind of projects leads to the extension of the BIM concept towards the historic or heritage BIM (hBIM).1 The consideration of the BIM concept as an emerging technology that enables us to understand, document, advertize, and virtually reconstruct the built heritage is not new. Besides the aforementioned potentials we still have many restrictions and challenges when using BIM supporting software to handle heritage sites and/or buildings for survey, documentation and dissemination. How to capture and describe the heritage site/building in BIM-supporting software? What are the potentials and challenges? Are there hBIM standards or guidelines? And how practicable are they? How flexible is the IFC data model behind the 3d model? How does hBIM meets the requirements of the building history researchers, conservators, project developers, planners and managers of heritage sites/buildings? This session will consider all these aspects (and hopefully more). Papers both on BIM/IFC theory as well as examples of BIM-conform 3d modeling of destroyed or still existing cultural heritage in practice in the real world are welcome.

Teaching Digital Methods

Call for Short Papers Nadine Alpino1 │ Stephen Stead2(1DOKU PLUS S.à r.l., Luxembourg | 2Paveprime Ltd., UK) Keywords: teaching, digital methods, exchange Every year we see presentations of fantastic results at CHNT which are, besides being traditional research, products of a range of digital techniques. We also see such digital methods becoming popular in spheres like of art and museums. It almost seems like everybody understands how these approaches work: but is that really true?  Have you ever tried to get a definition of a “point cloud” from a cultural heritage professional?Digital methods are still relatively new in the study of art history and some sub-disciplines of archaeology. So, how do we establish, teach and familiarise people who are as yet far from digital methods with their potential? Where are the sources of introductory material for the uninitiated on the fields of photo- and laser scanning, GIS, 3D-reconstruction and the myriad of other new techniques? How can we deliver an idea of the possibilities or create hand-on workshops that will inspire students and professionals alike?These and similar questions are the topics for our round table. We hope to discuss, exchange experiences and get an idea of the needs of the students in these disciplines. Most importantly we want to consider how to take this forward, perhaps by starting or joining an existing exchange platform, co-working with special interest groups or building a network of likeminded professionals. Time extent180 Minutes Duration of presentationsMaximum of 10 Minutes Target group(future) teachers, students, archaeologists, art historians, historians, members of special interest groups SubmissionMind the new...

Archaeological Prospection by Lidar Beyond Simple Hillshading

Call for Papers Irmela HERZOG1 | Michael DONEUS2(1LVR-Amt für Bodendenkmalpflege im Rheinland, Germany | 2University of Vienna, Austria) Keywords: Archaeological Prospection; Lidar; Digital Elevation Model For more than a decade, Lidar data has been used to detect and delimit archaeological sites by highlighting subtle altitude differences generated by the remains of these sites. In several European countries ordnance survey institutions nowadays provide Lidar data for archaeological purposes free of charge, and sometimes web map services are available that show hillshading views of this elevation data. Some researchers have pointed out the drawbacks of the ordnance survey Lidar data in their study area, favouring Lidar data acquisition commissioned by archaeologists. The latter procurement approach is the only option eligible in countries where official Lidar data is not accessible by archaeologists. In densely vegetated regions, filtering of the Lidar data is an issue. Additional issues include the accuracy of the measurements, irregular point density after filtering as well as combining data acquired in different campaigns or Lidar data with results of other prospection methods. Besides simple hillshading, several visualisation methods have been proposed that enhance detectability of specific archaeological features. Recently, pattern recognition and machine learning approaches have been used for the (semi-)automatic detection of sites in Lidar data, allowing to scan large regions with the aim of identifying sites of a predefined site type. The aim of this session is to show the potential of Lidar data beyond simple hillshading by papers focusing on: Best practice of Lidar data acquisition for archaeological purposesData filtering in densely vegetated regionsComparison of Lidar with SfM approaches in areas with hardly any vegetationPotential and limits of different visualisation approachesMonitoring sites by comparing Lidar data acquired in different yearsCombining Lidar data with data derived from other prospection methods(Semi-)automatic detection of sites in Lidar data for instance by machine learning approaches.
