Developing Tachy2GIS – Result and Perspective

Christian TRAPP1 | Reiner GÖLDNER2 (1Software Developer, Germany | 2Archaeological Heritage Office Saxony, Germany) Keywords: excavation, survey, total station, GIS The Hamburg Archaeological Museum maintains the development of basic components of “Tachy2GIS” (which is a real implementation of the “TachyGIS” idea). The existing prototype now is consolidated and extended due to basic requirements. By providing direct communication between a total station and the open source geographic information system QGIS, Tachy2GIS connects the well understood tool of the hand drawn map with the abilities of modern measuring equipment and geographic information systems. Drawing an excavation plan on a computer screen with a total station as stylus allows survey results to be reviewed and corrected in situ and immediately. Fig. 1. Digitization needs Analogization (© R. Goeldner) Geographic information systems are first and foremost map making software and Tachy2GIS is aimed at the archaeological community, which has special requirements towards said systems: Archaeological data is inherently very three-dimensional. There are almost always features on top of each other and also such that are much more vertical than flat. Both cannot be satisfactorily represented in a 2D top down view. Thus the next step is to add 3D interactive capabilities beyond the scope provided by QGIS in its current state.Right now we are researching how to achieve this, while keeping in mind that the typical laptop in the field will lack powerful graphics hardware. Progress is being made and we are looking forward to show off some implementation details. With this on the way, our eyes are set on extending the data acquisition side of Tachy2GIS to support a wider base of input hardware, which poses a new set of technological and financial challenges, as we need access to a variety of expensive devices which may use undocumented proprietary protocols.So the development is highly oriented on requirements of real archaeological excavations. It also follows principles of Free and Open Source Software to reduce overall expenses of the archaeological community. The short presentation will show results and perspectives of the Tachy2GIS developing project. ReferencesWorkshop „Digitale Grabungsdokumentation – objektiv und nachhaltig“, Dresden 2018-02J.

First Experiences Using TachyGIS in Excavation Practice

Christof SCHUBERT | Reiner GÖLDNER(Archaeological Heritage Office Saxony, Germany) Keywords: excavation, survey, total station, GIS Abstract:The importance of GIS in archaeology has been constantly growing over the last years, not only for analysis and interpretation, but also for on-site documentation. In cooperation with the Archaeological Museum Hamburg, Tachy2GIS has been developed as a QGIS plugin to allow “live” measurements with Leica total stations in QGIS. A prototype of this plugin has been tested over several months on excavations at the opencast mines near Weißwasser (Saxony). During these tests, the team improved the excavation specific geodata structure and developed a specific user interface to optimally support excavation workflows. The presentation will outline the current state, first experiences made in excavation practice and give an outlook on the further development of this FOSS project. Fig. 1.

Learning from the Past (Session introductory lecture)

Rowin J. VAN LANEN1, 2 | Menne C. KOSIAN1 | Jaap Evert ABRAHAMSE1 (1Cultural Heritage Agency of the Netherlands, landscape department, Amersfoort, The Netherlands | 2Wageningen University and Research, department of Soil Geography and Landscape (SGL), Wageningen, The Netherlands) How can we learn from the past? The importance of cultural heritage and GIScience for facing present-day challenges. Keywords: GIS, landscape dynamics, (historical) water management, climate-adaption strategies, political and societal influencing. Abstract:Throughout history people have had to adapt to changing environments. The forcing factors behind these changing environments are either of cultural or natural nature. Many of these factors are not unsimilar to the challenges we are facing today. Changes in climate, increased weather extremes, soil subsidence, water-regime changes, flooding, avulsions, soil conditions and demography have occurred throughout history and remain highly topical themes for modern-day societies. Knowledge on how people in the past have dealt with many of these challenges therefore can be not only an inspiration for modern-day planners and architects, but can also provide increased understanding and subsequent solutions for policy makers (e.g. politicians) and the general public. Consequently, cultural heritage plays a vital role in facing present-day and future challenges. In this introductory paper we will present a case study which shows how GIScience can help facing modern-day challenges. We will present a historic GIS developed at the Cultural Heritage Agency of the Netherlands (RCE). In this GIS, which is continuously being updated and expanded, data on the past natural and cultural landscape of the Netherlands (16th-19th centuries) are integrated with information on the present-day landscape. In the system data on historic city plans, palaeogeography and historical route networks are combined with information on historical-water systems. This allows us to use this GIS both for climate-adaptation strategies in both historical city centres (urban; local scale) and off site infrastructure such as water-management system (rural; regional scale). The GIS facilitates the integration of historical knowledge on urban and rural environments using land and water infrastructure. Such an integrated view is not only important from a scientific point of view, but also aids policymakers, technical engineers and planners and helps creating public awareness and support for cultural heritage...

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.

Hidden Florence

Fabrizio NEVOLA, University of Exeter, Exeter, UK Keywords: urban, geolocated, public history, mapping, engagement Abstract: Hidden Florence is a free app that lets you explore the Renaissance city through the eyes of historical characters, available free on AppStore and Google Play. By linking unconventional tours of Florence to the everyday lives of Renaissance Florentines, the app brings the people and places of the past to life while opening up a city overlooked by other guides. Navigate with a stunningly detailed map from 1584 – geolocated so you can toggle between it and a modern map of Florence – and walk in the footsteps of five contemporary guides, hunting for statutes, street tabernacles, palaces and piazzas. The characters are voiced by professional actors, including James Faulkner (Game of Thrones, Da Vinci’s Demons) as Cosimo de’ Medici. At each site the historians narrate ‘Discover More’ explainers and you can click through to the Hidden Florence website for in-depth historical context. Hidden Florence began as a prototype in 2014, with only one guide character. This new app has been written by an international team of historians of Renaissance Italy, and is a collaboration between the universities of Exeter, Cambridge and Toronto. Hidden Florence’s project partners are the National Gallery (London), Polo Museale della Toscana and Firenze Patrimonio Mondiale (UNESCO). The app is funded by the Arts & Humanities Research Council (UK) through the University of Exeter and is produced by Calvium. Project leader Professor Fabrizio Nevola (University of Exeter) said: “seeing Hidden Florence grow through a series of important collaborations with university colleagues, major galleries and other stakeholders is really exciting. We’ve brought a number of new stories about this city’s complex history to every visitor’s fingertips, using up to date technologies to present cutting edge research about gender, class and power in an accessible way”.
