AbstractIm Allgemeinen liegen Geodaten und georeferenzierte Daten verteilt vor, sind heterogen in ihrem Inhalt und ihrer Form, umfassen sehr große Datenmengen und müssen in verschiedenen IT-Informationssystemen integriert und in verschiedenen Anwendungskontexten genutzt werden. Im Mittelpunkt dieser Arbeit stehen deshalb Konzepte und Techniken für die Integration, Visualisierung, Analyse, Bereitstellung und Nutzung von 2D- und 3D-Geodaten sowie georeferenzierten Daten. Hierbei wird ein Ansatz verfolgt, der zum einen virtuelle 3D-Umgebungen als konzeptionellen und technischen Rahmen nutzt und zum anderen auf serviceorientierten Softwarearchitekturen und Geo-Standards basiert. Die vorgestellten Konzepte und Verfahren stellen damit Schlüsselbausteine dar, um neuartige IT-Lösungen und Anwendungen für 3D-Geoinformationen, z.B. als Bestandteile von Geodateninfrastrukturen, zu realisieren. Im Bereich der servicebasierten 3DGeovisualisierung beschreibt diese Arbeit, wie virtuelle 3D-Stadtmodelle für die Integration heterogener und verteilter Geodatenquellen genutzt werden können. Dazu werden Anforderungen für die Integration identifiziert und ein Konzept für die Integration auf Datenebene und die Integration auf Visualisierungsebene entworfen und deren Umsetzung am Beispiel komplexer 3D-Bauwerksinformationsmodelle beschrieben und demonstriert. Im Bereich servicebasierter, bildbasierter 3DPortrayal-Services wird mit dem Web View Service (WVS) ein spezialisierter SoftwareService für die Visualisierung, Interaktion und Analyse von geovirtuellen 3D-Umgebungen konzipiert und entwickelt. Kernkonzept dieses Services sind die serverseitige Datenintegration und -verwaltung sowie die ebenfalls serverseitige Bilderzeugung. Mit diesem durchgehend serverseitigen Ansatz können sehr große Mengen an 3D-Geodaten auch auf solchen Endgeräte bereitgestellt werden, die nicht über ausreichend Speicher und Rechenleistung für die Vorhaltung, die Verarbeitung und das Rendering von 3D-Modellen verfügen. Der entwickelte WVS ermöglicht so u.a. auch auf Tablet-PCs und im Webbrowser die interaktive Erkundung und Analyse von 3D-Geodaten. Anhand einer Referenzimplementierung des WVS und einer Client-Anwendung wird die praktische Anwendung des WVS demonstriert. Im Bereich der Komposition von Web View Services wird untersucht, wie der WVS als Baustein einer komplexen, verteilten Visualisierungs- und Renderingpipeline eingesetzt werden kann. Durch die Komposition des WVS mit anderen Darstellungs- und Verarbeitungsservices können z. B. komplexe Renderingeffekte erzielt oder einzelne 3D-Objekte nachträglich in eine 3D-Ansicht integriert werden. Hierzu wird ein Konzept zur servicebasierten, Tiefenbildbasierten Bildkomposition beschrieben und am Beispiel der verdeckungsfreien Annotation von 3D-Ansichten umgesetzt und demonstriert. Im Bereich der Interaktion mit Web View Services liefert diese Arbeit Grundlagen, Konzept und Umsetzung für intelligente, assistierende und automatisierte Interaktions- und Navigationstechniken, die auf dem Angebotscharakter (der Affordanz) von 3D-Szenenobjekten sowie auf der skizzen- und gestenbasierten Eingabe von Nutzerintentionen basiert. Diese Eingaben werden hinsichtlich ihrer Form und unter Berücksichtigung der Semantik der 3DSzenenobjekte ausgewertet und interpretiert und anschließend in anwendungsspezifische Navigationskommandos übersetzt, aus denen teilautomatische Kamerafahrten abgeleitet werden.

AbstractVirtual 3D city models provide powerful user interfaces for communication of 2D and 3D geoinformation. Providing high quality visualization of massive 3D geoinformation in a scalable, fast, and cost efficient manner is still a challenging task. Especially for mobile and web-based system environments, software and hardware configurations of target systems differ significantly. This makes it hard to provide fast, visually appealing ren-derings of 3D data throughout a variety of platforms and devices. Current mobile or web-based solutions for 3D visualization usually require raw 3D scene data such as triangle meshes together with textures delivered from server to client, what makes them strongly limited in terms of size and complexity of the models they can handle. This paper introduces a new approach for provisioning of massive, virtual 3D city models on different platforms namely web browsers, smartphones or tablets, by means of an interactive map assembled from artificial oblique image tiles. The key concept is to synthesize such images of a virtual 3D city model by a 3D rendering service in a preprocessing step. This service encapsulates model handling and 3D rendering techniques for high quality visualization of massive 3D models. By generating image tiles using this service, the 3D rendering process is shifted from the client side, which provides major advantages: (a) The complexity of the 3D city model data is decoupled from data transfer complexity (b) the implementation of client applica-tions is simplified significantly as 3D rendering is encapsulated on server side (c) 3D city models can be easily deployed for and used by a large number of concurrent users, leading to a high degree of scalability of the overall approach. All core 3D rendering techniques are performed on a dedicated 3D rendering server, and thin-client applications can be compactly implemented for various devices and platforms.

AbstractGeoreferenced data is available from a wide range of sources, e.g., Directory Services, Sensor Observation Services, Web Feature Services or even proprietary interfaces. Many of the data originating from an Internet of things will be threedimensional representing outdoor as well as indoor geographic features and their properties. Based on this data, its integration, and its visualization totally new applications and systems could be designed and implemented supporting various applications domains. Recent work in the area of service-based 3D visualization enables high-quality visualization of complex 3D geodata, e.g., 3D city models and 3D indoor building models, on thin clients as well as mobile devices such as smartphones and tablets. This work uses a service-based, image-based visualization approach that decouples the server-side resource-intensive management and rendering of complex, massive 3D geodata from client-side display functionalities: A Web View Service provides image representations of a 3D scene, these images, which can contain different types of information per pixel, are transmitted to a client application that can reconstruct a 3D representation of this scene. – In this talk, we will describe how to combine 3D geodata originating from the Internet of Things with this service-based approach in a way that allows for the interactive exploration of and interaction with 3D worlds and objects of interest. In detail, this 3D geodata can be integrated into the visualization process a) at the rendering stage of a portrayal service, b) through an image post processing step or c) in the client application itself. Moreover, this data can be visually represented directly by modifying the appearance of existing features, e.g., for visualizing measurements, or indirectly by introducing additional objects, e.g., icons, into the 3D scene. We will discuss advantages and disadvantages of these different approaches for implementing visualization applications using live geodata sources.

AbstractVisualization of 3D geovirtual environments enables users to gain insight into and to interactively operate with complex 3D geoinformation as well as to explore and analyze underlying structures, relationships, and associated thematic georeferenced data. It represents a key functionality for a growing number of applications and systems such as for way-finding, urban city planning, geo-marketing, and tourist information. For the systematic implementation of these systems, geoinformation services provide an interoperable and standardized way to access, process, and view distributed, heterogeneous 2D and 3D geospatial data. To broaden the use and scope of 3D geovirtual environments, we have to support the management and visualization of user-defined or application-defined data associated with geospatial objects. For this purpose, we can embed annotations such as texts or symbols as meta elements into images of 3D geovirtual environments. For example, annotations can represent georeferenced comments added interactively by the user to explicitly denote spatial objects and locations the comments refer to. This paper presents the design of a chain of web services for the creation of annotated perspective views. First, a Web Perspective View Service (WPVS) is outlined that synthesizes images of a given 3D geovirtual environment and delivers the images to the service consumer. Second, the Web View Annotation Service (WVAS) is introduced that processes these images as input along with a set of spatial locations and content definitions. To ensure high legibility, annotations are embedded into the view plane and placed such that they avoid occlusions among themselves and with geospatial objects of the scene. As result of this service composition, the service consumer receives an enhanced image depicting the current perspective view with seamlessly embedded annotations. We describe the design and system architecture by the example of a prototypic interactive campus information system.
