<p>This poster has been presented during the conference Der Fachaustausch Geoinformation (http://www.fachaustausch-geoinformation.de/) organized by GeoNet.MRN to exhibit the semantic geographic information system developed in the context of SemGIS project. The poster shows the approaches used to integrate heterogeneous data sets from different sources. These data sets can then, be enriched through resources from the Semantic Web. An example of such enrichment is presented from an integrated XErleben data. Finally, it illustrates the functionalities of the system to query and visualize data, but also the downlift of selected data according to different standardized formats.</p>

<p>This position paper highlights current problems linked to the aspects of the multi-agency collaboration during disaster response. The coordination and cooperation depend on the information sharing and use which must face up to interoperability, access rights, and quality problems. The research project aims at providing an assessment of information impact on the disaster response in order to support the decisionmaking about what information shared or what quality of data used to improve the response efficiency. Our research approach propose to combine an information system able to integrate heterogeneous data and a simulation system to assess different strategies of information sharing, dissemination and use. A knowledge base is used as a bridge between information system and simulation system. This knowledge base allows for designing dynamically a simulation according to open data and for managing the own knowledge and information known by each agent.</p>

<p>Photogrammetrie ermöglicht es, Objekte mithilfe von Digitalbildern zu vermessen. Bei optimalen Messbedingungen sind Qualitätsunterschiede der abgeleiteten Maße vor allem auf die mathematische Modellierung des verwendeten Sensors und des Objektivs zurückzuführen. Photogrammetrische Kalibrierungen erfolgen meist mittels Bündelblockausgleichung. Diese gestattet es, vielerlei statistische Kennzahlen abzuleiten. Eine tiefer gehende Analyse der berechneten Parameter, Standardabweichungen, Korrelationen und deren Verteilungen kann Aufschluss darüber geben, ob das verwendete Kalibriermodell Schwächen aufweist. Solche Defizite können sich durch systematische Restfehler im Bild- oder Objektraum äußern. Da solche Restfehler auch zu Ungenauigkeiten in den daraus abgeleiteten Informationen führen können, ist deren mathematischer Nachweis und anschließende Kompensation zur Erzielung höchster Genauigkeiten unausweichlich. Neueste Ansätze nutzen Korrekturterme, um Residuensystematiken schon während der Bündelblockausgleichung zu modellieren. Dieser Beitrag beschreibt, wie auch Machine-Learning-<br />Techniken dabei helfen können, verbliebene systematische Abweichungen in Bildresiduen nachzuweisen, ohne dass hierzu ein Eingriff in die Bündelblockausgleichung notwendig ist. Dies wird im ersten Schritt anhand von Beispieldaten erläutert. Im zweiten Schritt wird die Wirkung dieser Vorgehensweise an einer realen Kamerakalibrierung verdeutlicht. Abschließend erfolgt eine Diskussion der im Zuge dieser Arbeit erzielten Resultate und möglicher Eignung dieses Verfahrens in der Praxis.</p>

Besides operational functionalities and technical parameters such as measurement principles, instruments, and setups further factors such as the targeted application, data, physical characteristics of the object, and external influences are considered creating a holistic view on spectral and spatial recording strategies. Through this approach impacting factors on the technologies and generated data are identified. Semantic technologies allow to flexibly store this knowledge in a hierarchical class structure with dependencies, interrelations and description logic statements. Through an inference system the knowledge can be retrieved adapted to individual needs.</span></p>

<p>This paper addresses the factors that conditioned the choices in lithic resource procurement for tool making at the Late Aurignacian site of Stratzing-Galgenberg (Austria), based on the lithic assemblage from the main area of the site. The raw materials used in the analysed assemblage are varied and partly relate to various local and non-local proveniences. The importance of non-local flint in the assemblage contradicts the distance decay model according to which the amount of a given raw material decreases with the increasing distance from its source. Drawing on the approach developed recently by Lucy Wilson, we examine the predictive ability of &ldquo;source attractiveness&rdquo; with respect to terrain difficulty and energy expenditure to understand why some sources were used more than others, using a Geographic Information System (GIS). Our results indicate that terrain difficulty and mobility costs matter and have a better predictive ability than Euclidean distance alone to explain assemblage variability in the Aurignacian of the Middle Danube region.</p>

<p><span class="foldable-text" data-reactid="122" id="yui_3_14_1_1_1505396336545_1222">For several years, many researchers tried to semantically integrate geospatial datasets into the semantic web. Although, there are many general means of integrating interconnected relational datasets (e.g. R2RML), importing schema-less relational geospatial data remains a major challenge in the semantic web community. In our project SemGIS we face significant importation challenges of schema-less geodatasets, in various data formats without relations to the semantic web. We therefore developed an automatic process of semantification for aforementioned data using among others the geometry of spatial objects. We combine Natural Language processing with geographic and semantic tools in order to extract semantic information of spatial data into a local ontology linked to existing semantic web resources. For our experiments, we used LinkedGeoData and Geonames ontologies to link semantic spatial information and compared links with DBpedia and Wikidata for other types of information. The aim of our experiments presented in this paper, is to examine the feasibility and limits of an automated integration of spatial data into a semantic knowledge base and to assess its correctness according to different open datasets. Other ways to link these open datasets have been applied and we used the different results for evaluating our automatic approach.</span></p>

<p>The activities of COSCH community and the disciplines it represents were as diverse as they could possibly be in research into cultural heritage. To achieve common goals it was of utmost importance to have a common understanding of these diverse activities and disciplines. Work on the COSCH Knowledge Representation, or COSCHKR, was undertaken to develop a common semantic base representing different disciplines and to facilitate communication within the Action. The COSCHKR is an ontology-based inference model, guided by inference rules that provide a semantic bridge between various interdisciplinary activities involved in non-invasive technical documentation of material cultural heritage. The model is intended to support humanities experts by recommending optimal spatial and spectral techniques. The model may also be used by technology experts to compare their own solutions with the ones recommended through COSCHKR, and to understand why they may differ.<br />In this chapter we present the methods adopted for designing the COSCHKR and the steps in the development of the inference model. The difficulties in maintaining a common level of understanding within the diverse disciplines during the knowledge acquisition process are discussed. We present mechanisms and methods of information collection, its structuring, and aligning, to formulate different axioms and theorems within the model. The design and development of COSCHKR was based on an iterative procedure where the gathered knowledge was first verified with the group of experts before it was processed. This verification mechanism was important for the reliability of the model, ensuring technical consistency. This chapter highlights the importance of these iterative mechanisms in the validation of knowledge gathered and then information populated inside the knowledge base.</p>

<p>Ontologies have traditionally been used to represent knowledge of a specific domain. They are also used to provide a base to infer the knowledge present inside them. However, the applications of ontologies within the Cultural Heritage (CH) community have been restricted to providing standard documentation for significant heritage objects. E.g., widely used ontology within CH disciplines, International Committee for Documentation Conceptual Reference Model (CIDOC CRM) is designed to provide standards in documenting archival information of physical CH object. There has been hardly any work relating the objects to their documentation purposes. In this paper, we present the Colour and Space in Cultural Heritage Knowledge Representation (= COSCHKR) ontology &ndash; a multi-faceted ontology. With COSCHKR, we present a system that infers inter-woven descriptive semantics of different involved CH disciplines in recording CH objects to recommend optimal spatial and spectral technical solutions to humanities experts and guide through the underlying complexities while recording their objects. It takes numbers of facts into consideration including physical characteristics of the CH objects, the characteristics of their surroundings and even other relevant facts such as budget or staff competence to infer against the characteristics of the technologies for a proper recommendation. In contrast to a typical Recommender System, which does the same for web-based content through stochastic methods, we use descriptive semantics at the concept level.</p>

<p>From autumn 2010 to spring 2013 the German Archaeological Institute and the Swiss Institute for Architectural and Archaeological Research on Ancient Egypt continued the investigation of the city and temples of Elephantine (Aswan). The preliminary report presents the results of some of the projects conducted during this period.<br />As part of the ongoing rehabilitation work at the museum buildings located on the island of Elephantine, excavations were conducted near the northeastern limit of the ancient town. Among the earliest remains found in the area is a well preserved section of the city wall of the late 2nd dynasty. Outside the perimeter of this wall Nile sediments dating to the Old Kingdom were identified, as well as settlement remains of the 6th to 12th dynasties. Several pottery kilns of the early Middle Kingdom were discovered here. A later city wall appears to have been constructed during the reign of Senwosret III and it seems to have existed until the early New Kingdom.<br />The documentation and study of the relief blocks originating from the Khnum temple of the New Kingdom was continued. Many of the blocks can be attributed to the temple house, the courtyard and the first pylon built by Thutmosis III, as well as to the festival courtyard which was added by Amenophis II. Some of the blocks appear to originate from other, so far unknown buildings of the temple complex, including a cult building of Thutmosis I and II, a barque station of Hatshepsut and a construction of Thutmosis IV.<br />The aim of another project has been the investigation of workshop areas of the Late Antique Period. During the excavation of a house dating to the 5th&ndash;9th centuries AD, evidence for the baking of bread, the keeping of animals and the production of granodiorite bowls has been found. Nearby an oven used for smelting non-ferrous metal was identified. Fragments of melting pots, casting molds and slag provide information on the production process.</p>

<p>Shared thesauri of concepts are increasingly used in the process of data modelling and annotating resources in the Semantic Web. This growing family of linked data resources follows a top-down principle. In contrast, the Labeling System follows a bottom-up approach, enabling scientists working in the digital humanities to manage, create and publish their own controlled vocabularies in SKOS (Simple Knowledge Organization System). The created concepts can then be interlinked with well-known LOD (Linked Open Data) resources, a process named the &lsquo;Labeling Approach&rsquo;. The Labeling System is domain independent, while uniting perspectives of different scientific disciplines on the same label and therefore contributing to interdisciplinary collaboration for building up cross and inter-domain linked data communities. This paper addresses principles of the Labeling System in the light of archaeological use cases.</p>

<p>Application and analysis capabilities of 3D data sets generated through UAV photogrammetry are presented on the basis of an exemplary millstone quarry of the so-called Mayen quarry district (Germany). In general, millstone quarries are technical cultural heritage sites which give evidence for economic interpretations as they are of interest for the reconstruction of ancient procurement patterns. Particularly those quarries which had a high economic impact cover large areas with often arduous accessibility. Therefore, photogrammetric recording using a UAV is the best approach for fast and inexpensive high-quality documentation. The images are used to create a 3D data set and orthophoto. For analysis and interpretation the Spatial Image analysis and Visualisation Tool (SIVT) of i3mainz is used allowing a variety of interactive visualization functionalities. The 3D data are transformed into 2.5D data enabling segmentation of spatial information and volume calculations. Both functionalities support the cultural heritage expert&#39;s research: On the one hand the interactive segmentation allows producing a map of the quarry displaying only those parts associated with the extraction. On the other hand the output of the quarry including debris and millstone blanks can be calculated easily. All in all, the entire workflow beginning with data capture using a UAV followed by data processing, (2.5D / 3D) data analyses and visualisation of the results is presented.</p>

<p>Mit INSPIRE &ndash; der Geodateninfrastruktur der Europäischen Gemeinschaft &ndash; wird das Ziel verfolgt, umweltrelevante und harmonisierte Geodatenbestände für eine nachhaltige europäische Umweltpolitik und zur allgemeinen Bereitstellung für die Bürger der EU verfügbar zu machen. Die Konzeption und Umsetzung von Diensten der Behörden in Europa muss auf der Grundlage von vernetzten Datenbanken erfolgen. Zur Gewährleistung einer Interoperabilität zwischen den verschiedenen Ebenen und Systemen ist es zwingend notwendig, dass auf den verschiedenen Ebenen die Behörden und Systeme über gemeinsame Standards kommunizieren. Dabei sind sowohl semantische, syntaktische und organisatorische Rahmenbedingungen der Verwaltungen zu berücksichtigen. Diese spiegeln sich vor allem in den vorhandenen E-Government-Aktivitäten, Standardisierungen und Geoinformationssystemen (GIS) der Verwaltung wider. Zur Realisierung einer Geodateninfrastruktur in der Europäischen Gemeinschaft sollen die Mitgliedsstaaten ihre bereits vorhandenen Geodatensätze und -dienste stufenweise interoperabel verfügbar machen. Damit soll die Entscheidungsfindung in Bezug auf politische Konzepte und Maßnahmen, die direkte oder indirekte Auswirkungen auf die Umwelt haben können, unterstützt werden. Jedoch haben die gewachsenen Verwaltungsstrukturen in Städten und Landkreisen mit ihren jeweiligen Besonderheiten zu heterogenen Datenbeständen geführt. In dem entwickelten E-Government-Modell einer Geodateninfrastruktur (Geo-Government) kann Interoperabilität auf allen Ebenen nachgewiesen werden.</p>

<p>Spatial and spectral recording of cultural heritage objects is a complex task including data acquisition, processing and analysis involving different technical disciplines. Additionally, the development of a suitable digitisation strategy satisfying the expectations of the humanities experts needs an interdisciplinary dialogue often suffering from misunderstanding and knowledge gaps on both the technical and humanities sides. Through a concerted discussion, experts from the cultural heritage and technical domains currently develop a so-called COSCH KR (Colour and Space in Cultural Heritage Knowledge Representation) platform that will give recommendations for spatial and spectral recording strategies adapted to the needs of the cultural heritage application. The platform will make use of an ontology through which the relevant parameters of the different domains involved in the recording, processing, analysis, and dissemination of cultural heritage objects are hierarchically structured and related through rule-based dependencies. Background and basis for this ontology is the fact that a deterministic relation exists between (1) the requirements of a cultural heritage application on spatial, spectral, as well as visual digital information of a cultural heritage object which itself has concrete physical characteristics and (2) the technical possibilities of the spectral and spatial recording devices. Through a case study which deals with the deformation analysis of wooden samples of cultural heritage artefacts, this deterministic relationship is illustrated explaining the overall structure and development of the ontology. The aim of the COSCH KR platform is to support cultural heritage experts finding the best suitable recording strategy for their often unique physical cultural heritage object and research question. The platform will support them and will make them aware of the relevant parameters and limitations of the recording strategy with respect to the characteristics of the cultural heritage object, external influences, application, recording devices, and data.</p>

<p>Die <strong>Partizipation der Bürger</strong> ist ein wesentlicher Bestandteil moderner Demokratie, welche bei Planungsaufgaben der Kommunen zukünftig einen noch höheren Stellenwert einnehmen soll. Mit der Einführung von Geo-Informationssystemen (GIS) in kommunalen Verwaltungen, ist in den letzten Jahren die <strong>Nutzung digitaler Geodaten</strong> stetig gestiegen. Deren elektronische Bereitstellung sowie die Nutzung moderner Informations- und Kommunikationstechniken im Internet, bieten für Partizipation sehr große Chancen für die Verwaltungen und die Bürger:</p><ul><li><strong>Aktive Teilhabe</strong> der Bürger an Entscheidungsprozessen in Politik und Verwaltung.</li><li><strong>Transparenter Zugriff</strong> auf Informationen aus dem Bereich Planung, Bauen, Energie und Umwelt.</li><li>Förderung der <strong>elektronischen Kommunikation</strong> mit dem Planungsträger.</li><li><strong>Stellungnahmen</strong> können auf elektronischem Wege, unabhängig von Erreichbarkeit und Öffnungszeiten übermittelt werden.</li><li>Elektronische Partizipation als eine <strong>neue Form der Wissenskommunikation</strong>.</li><li>Geodaten sollen der <strong>Veranschaulichung der politischen Entscheidungsprozesse</strong> und der Beteiligung dienen.</li></ul><p>Dieser als <strong>&bdquo;Geo-Partizipation&quot;</strong> bezeichnete Forschungsansatz gilt in Anlehnung an den Begriff &bdquo;E-Partizipation&quot; für die IT-gestützten Beteiligungen, bei denen der Raumbezug in Form von Geoinformationen eine wichtige bzw. entscheidende Rolle spielt. Damit kann eine Nutzung von GIS nicht nur für die Erstellung von Planungen, sondern ein ganzheitliches Beteiligungsinstrument mit Geodaten der Verwaltung ermöglicht werden. Dazu zählen sowohl <strong>formale Beteiligungsverfahren der kommunalen Bauleitplanung</strong>, als auch informelle Verfahren der Stadtentwicklung oder der Dorferneuerung. Die im Bericht vorgestellte <strong>Internet-Plattform kann als Prototyp</strong> einer operativen &bdquo;Geo-Partizipation&ldquo; angesehen werden, welche für die Kommunen im Projekt des Instituts für Raumbezogene Informations- und Messtechnik (i3mainz) die Partizipation in Planungsverfahren unter besonderer Berücksichtigung des Raumbezuges ermöglicht.</p>

<p>Die luxuriös ausgestatteten Wohneinheiten des am Nordhang des Bülbüldağ gelegenen Hanghauses 2 wurden im 3. Viertel des 3. Jhs. durch eine schwere Erdbebenserie zerstört. Statt die Wohnungen wiederaufzubauen, wurden bereits kurze Zeit nach der verheerenden Katastrophe mit Wasserkraft angetriebene Mühlen eingerichtet. Im Befund sind insgesamt acht Wasserradgerinne mit jeweils einer zugehörigen Mühlstube bzw. Werkstatt erhalten. Sie lassen sich drei Bauphasen zuordnen, die in das 4., 5./6. und Ende des 6./Anfang des 7. Jahrhunderts datieren. In der am besten erhaltenen Phase sind insgesamt fünf Räder hintereinandergeschaltet. Neben einer Steinsäge wurden vier Mahlgänge zur Mehlproduktion angetrieben. Eine große Personenanzahl konnte so mit dem wichtigsten Grundnahrungsmittel versorgt werden. Die Mühlenanlage wird in den städtischen Kontext von Ephesos gesetzt und mit anderen Mühlenanlagen verglichen.</p>

<p>Cultural Heritage (CH) visualisations have to be understood as a combination of research sources, the contemporary historical and cultural context (Zeitgeist), project background and work process. All available information is collected, consolidated, filtered and assembled into a coherent picture. In case of digital 3D reconstructed models, the result is a digital data set that can be processed for different application fields. They are understood as a result of a complex creative process and as a synthesis of a CH research project, its CH context, the available research source material, and the modeling process itself. For all visualisation types in CH different conditions, factors, and basic rules apply to achieve a high quality result. Two examples are presented illustrating the structured view on visualisation projects as such. This paper seeks to differentiate the various research sources being the basis for digital 3D reconstructed models and defines work phases allowing a quality assessment. Furthermore, the potentials of including this structured view into the ontology COSCHKR currently under development is discussed. In combindation with traditional guidelines COSCHKR platform could open up new and flexible approaches.</p>
