1 Industry Value and Benefit of Computer Based Visualization of 3D Terrain and Land Use Models Dr. Michael Beck, Dr. Thomas Blaser & Rüdiger Mach 1 Abstract A new way to handle complex Geo Data with additional content is the use of Virtual Globes. Virtual Globes may be described as specialized toolboxes for preparing all kinds of data for highly interactive geo d use combined with extra 3D information. This article is about Virtual Globes - what they are, where they come from, where their advantage may be found, who is on the market and where we are heading for. 2 Introduction This article is a review of the current state of Virtual Globe solutions, their markets and respective applications. As so many different facts, descriptions and new ideas form a part of the discussion, it is important to talk about features, content and meaning of Virtual Globes. So let s focus on some basics about this fascinating field of Virtual Globe Solutions. To call a system Virtual Globe it has to be able to handle a lot of different files, content and technologies. Getting in touch with all the descriptions and definitions of geographical data (Geo Data) and information one may become confused due to the linkage and interconnection of the various disciplines and players in these markets: GIS, 3D Computer Graphics, Remote Sensing, 3D Visualization and more. 2.1 Some Definitions A Virtual Globe can be described as a system representing Geo Information and Content with regards to one (e.g. WGS 84 1 ), including imagery, digital maps, elevation and 3D models, vector data, weather data, and data from Real- Time GPS or surveillance systems (satellites, planes, helicopters, UAV 2 s, cameras). Virtual Globe applications provide functionality for accurate representation of the Earth up to a very detailed level, for 3D visualization and navigation UAV - Unmanned Aerial Vehicle
2 2 Introduction Virtual Globes can represent and combine geo d data from different sources and systems: Remote Sensing is in the broadest sense the measurement or acquisition of information of an object or phenomenon by a recording device that is not in physical or intimate contact with the object. In practice, remote sensing is the utilization at a distance (as from aircraft, spacecraft, satellite, or ship) of any device for gathering information about the environment. A geographic information system (GIS) is a system for creating, storing, retrieving, analyzing, displaying and sharing geographically-d spatial data and associated attributes. Cartographic modelling refers to a process where several thematic layers of the same area are produced, processed, and analyzed. Dana Tomlin (1990) used raster layers but the overlay method can be used more generally. Operations on map layers can be combined into algorithms, and eventually into simulation or optimization models. Digital cartography can be considered a (semi) automated process of producing maps from a GIS system. The representation of GIS output through a digital map is considered equivalent to the stage of visualization. The main factors in the creation of an interactive Virtual Globe solution can be described as follows: 1. 3D Globe Geo Content A Virtual Globe solution has to be able to represent the most important types of geo information such as elevation information, imagery, vector delineations and surfaces and annotations. 2. 3D Models - Additional 3D models are important in order to create a convincing Virtual Globe solution (entire cities and textured buildings, landmarks, plants and production facilities, power lines, road, railway and pipeline networks, street culture, vegetation, dynamic 3D objects such as planes, cars, people). 3. Navigational Information For navigation, Points of Interest, Flight paths and so called Hot Spots are important. They make it easier for the users to retrieve local information and to find their way. 4. Navigation The navigation has to be simple, easy and instinctive. If it is a Flythrough or a Walkthrough or just a Find Target, the user has to get familiar with the system in a very short time. Using the mouse or a joystick to navigate in an intuitive way is one of the most effective ways of getting the solution accepted. 5. Web Based Application - Internet revolutionized the way we communicate with each other and share knowledge and information.
3 Industry Value and Benefit of Computer Based Visualization of 3D Terrain and Land Use Models 3 Therefore the hosting and streaming of 3D Geo Data, Terrain Models and additional information inside a web based environment is a basic requirement. 6. Webcams, Intelligence and Remote Control - Spatial representation of moving or stable objects in 3D on the ground or in the air through the help of intelligence and reconnaissance technology (satellite-, UAV-, Webcam data streams, GPS) is a very important necessity. While the Network Centric Intelligence Technology has its origins in defence and domestic security, civil applications can include endangered species, wild animals surveillance, or live event broadcasting. 7. Presentation and communication - Presentation and communication of complex data for the public is an important detail. Any type of Globe-related enterprise or project to plan and implement (e.g. engineering, urban land use planning, architecture, network infrastructure, navigation, security, defence, United Nations missions) needs adequate presentation and communication platforms to various audiences. 8. Large Screen Presentation - In professional use, larger screen dimensions are needed for command and control (launch of the space shuttle, air control, and more) as well as in the fields of virtual reality, flight simulation and entertainment, where multi-channel and multiprojection screens allow immersive visualizations and experience with virtual 3D landscapes. 3 The way to Virtual Globes - the last years The Geo software industry has realized the importance of Virtual Globes. ESRI 3 launched ArcGlobe in mid-2003 and Google its Google Earth in Leica Geosystems 4 from Hexagon commercializes ERDAS Imagine and Virtual Explorer software. Intergraph 5 has a product called Image Viewer for MicroStation. Autodesk 6 has acquired sophisticated software for high quality 3D modelling, visualizations and animations, such as Autodesk Civil3D, 3ds Max or Maya. The Swiss Company ViewTec has been developing software products since the late 90 s which are branded under TerrainView TM. Today they define the major applications within industrial use of interactive visualization and Globe Solutions
4 4 The way to Virtual Globes - the last years Upstream core technologies required for the realization of applications with Virtual Globes are Remote Sensing and imagery acquisition (satellite, aerial, terrestrial) Image processing, ortho-rectification and projection Geographical & other spatial information processing Global positioning systems (satellites, receivers, emitters) 3D Modelling Tools to create additional information and include designs and constructions The following figure describes the workflow needed in generating Virtual Globes and models in 3D: Fig. 1 Workflow needed for generating Virtual Globes and 3D models 3.1 GIS vs. Virtual Globes? As mentioned above, the origins and uses of GIS and Virtual Globes differ from each other. The main difference is that GIS is used for queries and analysis, while Virtual Globes are used mainly for visualization, localization and navigation.
5 Industry Value and Benefit of Computer Based Visualization of 3D Terrain and Land Use Models GIS Visualizing Abstract Information A GIS can be represented in a Cartesian coordinate system through l=m+n layers. m represents the number of geo d and superposed thematic maps and n the number of times, a natural phenomenon (e.g. retrogression of a glacier) can be observed over time Virtual Globe A Visualization for the User Observers use cognition and context for 3D scenes interpretation and description. Although less mathematical than GIS, the 3D visualization of detailed terrain data will bring into evidence e.g. lineaments, fractures and other terrain features. For visualization, imagery from different spectral wavelengths (visible, infrared, thermal infrared, radar spectra) and resolutions can be used. Typically, the sensor resolution should be less than half the size of the smallest feature that must be resolved (Jensen, 1996). 4 Applications & Features 4.1 Applications Some applications are trying to conquer the market. The most well-known are: Viewtec TerrainView-Globe Google Earth Microsoft MSN Virtual Earth NASA and World Wind WW2D Viewtec TerrainView-Globe TerrainView-Globe TM enables the user to interact with 3D visualizations in spherical rendered scenes.
6 6 Applications & Features Fig. 2 Rendering of Earth s Globe from NASA with ViewTec s TerrainView- Globe TM software. TerrainView-Globe TM functionality includes definition of camera and flight paths allowing 3D terrain and models to be recorded and viewed as animations and videos, integration of 3D terrain models and textured high-definition 3D objects (i.e. Plug-In for 3ds Max). continuous level of detail while zooming with any number of overlapping, high-resolution image or terrain data inserts, terrain morphing between different resolution levels, ultra-fast Level-Of-Detail calculation, demand paging of tiled data for the four basic data types: imagery, terrain, vector, annotation.
7 Industry Value and Benefit of Computer Based Visualization of 3D Terrain and Land Use Models Google Earth Google Earth 7 might be called the Virtual Globe solution for the masses. Google Earth s vision is that "open source" projects, people build, will make data content grow over the entire Globe Microsoft MSN Virtual Earth Microsoft s MSN Virtual Earth 8 is the server part of Windows Live Local, a free online local search and mapping service. Functions allow the exploration of a specific location with advanced driving directions and local listings NASA and World Wind World Wind 9, is NASA's Learning Technologies project, an open source 3D interactive world viewer to maximize awareness and impact of NASA research WW2D WW2D 10 is a free cross-platform, Open Source Java and OpenGL based application (Vitaliy Pronkin). WW2DplusOne provides 3D viewing
8 8 Applications & Features 4.2 Virtual Globe Features The following table summarizes the features provided by each Virtual Globe Features Multiple image datasets Map, vector and annotation overlay Transparent overlay of multiple datasets Satellite and aerial image overlay Real time 3D weather overlay GPS generated data integration Textured 3D models (terrain, objects) Dynamic rendering of 3D elevation LOD Day & night, seasonal views and lighting Web community applications Collaborative computing ViewTec TerrainView- Globe TM Google Earth MSN Virtual Globe NASA World Wind WW2D ViewTec s TerrainView-Globe TM is for the professional markets and applications and thus clearly differs from applications such as Google Earth or Nasa World Wind which are more focused on public use/control and scientific research respectively. TerrainView-Globe enables rendering and display of global and local scale imagery, elevation, and vector-based datasets for all common projections, raster and vector formats. Local data can be used with internet based data services from ViewTec or other data provider. All datasets are independent with the ability to attach or detach. It can render an arbitrary number of datasets each with an arbitrary, potentially very large, amount of data and supports industry standard texture compression formats. A lossless compression of datasets further reduces disk and bandwidth requirements.
9 Industry Value and Benefit of Computer Based Visualization of 3D Terrain and Land Use Models 9 5 Geo Data Requirements Due to the fact, that there is a wide range of Geo Data service in the World Wide Web, applications that require 3D geographical data (3D Geo Data and content) will have to define: Geographic area Type of imagery and spectral bands Type of elevation data (e.g. digital terrain model, digital elevation model) Thematic information Spatial resolution Data accuracy (e.g. Root Mean Squared Error RMSE) Vector information & annotations Acquisition date Maximum cloud cover tolerated Data producing software While land cover imagery might be required more frequently the same DTM can be used for a longer period of time. 5.1 Data Provider Geo Data is available and distributed over the entire world. For Real Time or near Real Time data applications (security, defence, UN missions), data services are required around the clock. As an alternative, a data user might consider purchasing a satellite image reception station. The entire processing chain from raw data reception to spherical 3D data rendering in the Virtual Globe needs to be considered. 5.2 Remote Sensing and Measurement From a physical point of view, remote sensing is equivalent to the measurement of the reflected and emitted energy from the Earth s surface. To have comparable data over the entire Globe, radiometric calibrated and geometrically corrected and projected (WGS84) data is required. With Globe Systems like ViewTec s TerrainView-Globe TM various data sets (imagery, maps, textured models) at different resolutions can be combined. Each individual picture element (pixel) of each data set is precisely geo-d and - located. 5.3 Global Coverage Companies like ViewTec and Google provide Global coverage with Landsat 7 Enhanced Thematic Mapper satellite imagery (Dykstra 2006). Whether higher
10 10 Geo Data Requirements resolution Virtual Globes are required can be debated. Imagery is expensive and in many cases up-to-date information on a specific region is sufficient. 5.4 Various Disciplines and Data Needs Information and 3D visualization needs vary for each user and application. For example the placing of a pipeline will require a multidisciplinary effort, including specialists from various disciplines (law, geology, geophysics, soil science, ecology, hydrology, politics, economics etc.). It is therefore crucial to understand the different needs with regards to the Virtual Globe contents and resolution, 3D visualization and navigation. The following table tries to summarize industry (in alphabetical order) in combination with remote sensing data and DTM requirements.

Professional software like TerrainView-Globe TM provides customers the possibility to purchase software and data licenses, to benefit from services, and to manage and control their applications. The use of a Virtual Globe solution for the masses will create dependencies. There are no guarantees with regards to the sustainability of free Globe software, content and no quality assurance neither.
12 12 Conclusion 6.2 Potential of 3D Visualization The potential and adoption of Virtual Globes and 3D visualization technology in the Architecture, Engineering and Construction (AEC) industry might interest companies like Autodesk. Eastman et al. (2002) refer to the fragmentation inside the AEC industry as a major inhibitor of 3D technology adoption. The construction industry has traditionally been craftsman-oriented, with many small participants. Informing planners, architects, authorities, investors and the public in effective ways about a project means significant savings of time and money (Albrecht 2004). Prawel (2006) emphasizes the value of 3D software for innovation. From nuclear medicine to architecture, manufacturing to computer games, petrochemicals to weather prediction, 3D software technology is changing the way of communication. 3D visualization is communication support for our society and young generations are primarily visualization oriented. 6.3 What will be the future of Virtual Globes? Planning, simulation and monitoring in a computer generated realistic 3D world will increase the demand for Virtual Globe applications. Initiatives like Internet2, with a high-performance backbone network that operates at up to 100 Gbits per second 11, will dramatically increase usage and exchange of massive amount of data for 3D visualization. Collaborative virtual environments (CVE) the underlying concept used in TerrainView-Globe TM will connect people and projects across the entire world. Broadband access of wireless handheld devices to local real-time information, presented and geo-d in 3D will become a true value add (Grant 2006). 7 Conclusion Applications in the past, using 3D modelling, visualization and animation were based on expensive technology. Today, Virtual Globe applications run on Personal Computers. 3D technology has become accessible to everyone. While Google leverages its brand together with billions of USD investments to generate awareness and reach the Internet Community with Google Earth, ViewTec focuses on quality, value and the push of its TerrainView-Globe TM technology to develop new professional markets. As long as competition remains quasi-perfect Virtual Globe players like ViewTec can continue to benefit from Google Earth s momentum to drive innovation and to be successful in this market. 11 UCAID
