Implementing 3D Geovisualization in Spatial Data Infrastructures: The Pros and Cons of 3D Portrayal Services

Hildebrandt, Dieter; Döllner, Jürgen in Geoinformatik 2009 page 9 . 2009 .

Visual representations of geospatial information proved to be valuable means to facilitate thinking, understanding, and knowledge construction about human and physical environments, at geographic scales of measurement. Massive amounts of distributed and heterogeneous geospatial information and geospatial computing functionality are increasingly available as distributed resources that can be accessed through the Internet. This increased availability has created the demand and feasibility to build distributed systems that leverage these resources for visualizing and interacting with geospatial information. In this paper, we characterize, discuss, and compare the W3DS and WPVS portrayal services as proposed by the OGC with a particular focus on their application to portray complex virtual 3D city models. We discuss the potentials and limitations of the different approaches and the conditions under which they can be applied in an effective and value adding way. With this contribution, we aim at supporting decision makers in choosing portrayal services meeting their requirements for spatial data infrastructures (SDI), the present process of standardizing 3D portrayal services and related research.
