Unlike the traditional 2D-visualization typical of Geographic Information Systems (GIS), virtual globes offer multi-dimensional, fully-realistic content visualization which allows for a much richer user experience. This research investigates the potential for using virtual globes to foster tourism and enhance cultural heritage. The paper first outlines the state of the art for existing virtual globes, pointing out some possible categorizations according to license type, platform-dependence, application type, default layers, functionalities and freedom of customization. Based on this analysis, the NASA World Wind virtual globe is the preferred tool for promoting tourism and cultural heritage. -

Visualizing the Structure of the Earth's Lithosphere on the Google Earth Virtual-Globe Platform
International Journal of Geo-Information Article Visualizing the Structure of the Earth’s Lithosphere on the Google Earth Virtual-Globe Platform Liangfeng Zhu 1,2,3,*, Wensheng Kan 1,2, Yu Zhang 1,2 and Jianzhong Sun 1 1 Key Laboratory of GIS, East China Normal University, Shanghai 200241, China; [email protected] (W.K.); [email protected] (Y.Z.); [email protected] (J.S.) 2 School of Geography Science, East China Normal University, Shanghai 200241, China 3 Shanghai Key Lab for Urban Ecology, East China Normal University, Shanghai 200241, China * Correspondence: [email protected]; Tel.: +86-136-7172-1009 Academic Editor: Wolfgang Kainz Received: 15 January 2016; Accepted: 29 February 2016; Published: 2 March 2016 Abstract: While many of the current methods for representing the existing global lithospheric models are suitable for academic investigators to conduct professional geological and geophysical research, they are not suited to visualize and disseminate the lithospheric information to non-geological users (such as atmospheric scientists, educators, policy-makers, and even the general public) as they rely on dedicated computer programs or systems to read and work with the models. This shortcoming has become more obvious as more and more people from both academic and non-academic institutions struggle to understand the structure and composition of the Earth’s lithosphere. Google Earth and the concomitant Keyhole Markup Language (KML) provide a universal and user-friendly platform to represent, disseminate, and visualize the existing lithospheric models. We present a systematic framework to visualize and disseminate the structure of the Earth’s lithosphere on Google Earth. -
GIM Tool: a Global Icosahedral Atmospheric Model Viewer
GIM Tool: A Global Icosahedral Atmospheric Model Viewer Authors: Evan Polster, Jeff S Smith, Ning Wang CIRA researchers at Global Systems Division (GSD) of Earth System Research Laboratory (ESRL) GSD is developing two global icosahedral weather models: the finite-volume flow-following icosahedral model (FIM) [1] and the non-hydrostatic icosahedral model (NIM). Our group was tasked with developing an innovative 3D viewing application for the purpose of displaying such global model data, which would be web-based, and intuitive to use as an outreach and diagnostic tool. What Is An Icosahedral Grid? The icosahedral grid [2] is created by recursively bisecting the 20 triangular faces of the original regular polyhedral (icosahedron) and projecting bisection points to the sphere. The number of recursive refinements is referred to as grid level. The number of grid points is defined by N = 10 * 22g + 2, where g is the grid level. The areas of grid points are the spherical Voronoi cells defined by the grid points (Figure 1). Figure 1: The icosahedral grid mesh composed of 10242 Voronoi cells (at grid refinement level 5). Viewing Global Icosahedral Grids There is a myriad of ways to display global model data, but we will only discuss a few here. One option is to use a plotting tool that renders an orthographic projection of the gridded data as a static image. This projection offers a natural view of a hemisphere from a given center point. Modelers typically create these types of plots when they need to debug a model or analyze specific grid points (see Figure 2). -

The application is capable of visualizing n-dimensional data using a Voxel model. In this case study, we handled social media data and Call Detailed Records (CDR) of telecommunication networks. These were retrieved from the "BigData Challenge 2015" of Telecom Italia. We focused on the visualization process for a suitable way to show this geo-data in a 3D environment, incorporating more than three dimensions. This engenders an interactive way to browse the data in their real context and understand them quickly. Users will be able to handle several varieties of data, import their dataset using a particular data structure, and then mash them up in the WebWorldWind virtual globe. A broad range of public use this tool for diverse purposes is possible, without much experience in the field, thanks to the intuitive user-interface of this web app. -
How Virtual Globes Are Revolutionizing Earth Observation Data Access and Integration
HOW VIRTUAL GLOBES ARE REVOLUTIONIZING EARTH OBSERVATION DATA ACCESS AND INTEGRATION C.D. Elvidgea, *, B.T. Tuttleb aNOAA National Geophysical Data Center, Boulder, Colorado USA - [email protected] bDept. of Geography, University of Denver, Denver, Colorado USA - [email protected] Commission VI, WG VI/4 KEY WORDS: Virtual Globes, Remote Sensing, Geospatial Data. ABSTRACT: The fusion of the World Wide Web and spatial technologies has lead to the development of virtual globes which are increasingly serving as gateways to global geospatial data. Examples include Google Earth (originally Keyhole Earth Viewer), NASA's World Wind, ESRI's ArcGIS Explorer, Microsoft Virtual Earth, GeoFusions' GeoPlayer, Skyline Globe, ossimPlanet, EarthBrowser, and ESRI's ArcGlobe. These systems are revolutionizing earth observation data access and integration in two primary ways: 1) Democratization of access. The popularity of the openly accessible virtual globes extends far beyond the traditional professional communities engaged in geospatial science and commerce. The number of people interactively viewing and extracting content from earth observations such as satellite imagery is on a rapid upward swing as a result of virtual globes. For the technical users virtual globes have vastly reduced the overhead associated with accessing global archives of satellite imagery by eliminating purchase costs and effort required to stage and manage large image holdings. 2) Democratization of content contribution. Users are able to make links to their own earth observation data via web mapping services and insert site specific content (such as descriptions andphotographs) which can be openly accessed by the broader community. This has made it possible to integrate earth observation data from diverse sources, enable increased productivity for individual projects and studies. -

We aim to use high end modern technologies and programming language to create an interoperable Geographical Information Management Model in a Virtual Earth Environment where we can record history in an innovative and exploratory way. The first year graduate students at the Department of Geography at the University of Cincinnati have been taking a walking tour to Downtown Cincinnati from the campus since the 1980s. These tours have witnessed the continuing change of the city along the route, and these changes have only been documented in the essays written by students. This research aims to develop an online application in virtual environment that can show the current, historical, and future observations along the route. With the rapid development of online tools such as Google Earth and Microsoft Virtual Earth, it is now possible to create a geo-referenced archive of urban changes in a virtual geographic environment. -
Discover Google's Virtual Globe What Is Google Earth? Google Earth
Discover Google's Virtual Globe What is Google Earth? Google Earth combines satellite and aerial imagery, maps, terrain and 3D content with the power of Google's search service to provide a rich virtual atlas where you can discover useful information and educational resources in geographical context. There have been over 400 million unique downloads of Google Earth since the product's launch in June 2005. Similar to a video-game, Google Earth uses special navigation tools such as fly, zoom, pan, tilt and rotate to explore the world in 3D from your desktop or even from your mobile phone. Climb to the top of Mount Everest or descend the steepest gorges of the Grand Canyon without even breaking a sweat. Fly from outer space to the bottom of the Marianas trench in the western Pacific in the deepest part of the Ocean without leaving your armchair. View the 3D skyline of New York or travel back in time to see a historical representation of Ancient Rome at the click of a mouse. Here are some ideas for things you can see and do in Google Earth: Take a bird's eye view of the world: view satellite imagery for the whole world with sub-meter resolution for more than 30% of the world's land surface and 50% of the world's population. Travel to new places: learn about new destinations through videos, photos, reviews and other user-generated content. See information in context: Google News and New York Times articles, Wikipedia entries, Google Book Search and much more all geo-tagged to their relevant location.
