Both GE and World Wind use dynamic bounding box (BB) parameters to create an image of the WMS request. The WMS connection to MSN VE 3D is quite different from GE and World Wind. Each connection was tested using UMN Map Server and Geoserver, revealing significant differences. Table 2 compares various WMS–viewer connection properties. However, these viewers have limitations regarding the projection of a WMS on a 3D surface. GE, MSN VE 3D and WW may all be connected to WMS (using GetMap request). The wms_server_list.xml file had to be changed and new WMS requests added. Adding a WMS to WW simply required some configuration files to be adjusted. WW has a ready-made WMS connectivity feature. Only the WGS84 coordinate system was found suitable for proper projection in MSN VE 3D.

A WMS was added to MSN VE 3D interface by building a demo website that included four WMS layers it uses the VEAddTileServer Specification as described in the online Software Development Kit (SDK) to run WMS GetMap request as a tile server. The 3D-barriers were constructed using Google Sketchup. General users may click on the sound barrier to obtain information on its dimensions. Height information relating to planned sound barriers along a bypass at the Dutch town of Eindhoven was combined with WMS projections on GE. An existing Geoservices internet application was used as pilot WMS. We coupled the Geoservices Web Mapping Server (WMS) infrastructure with GE, using the Network Link tool that adds RWS-AGI map servers and overlays raster-WMS maps on a GE client using a KML Ground Overlay element attribute. Although WW is supplied with relatively low-resolution satellite and aerial imagery, it is capable of importing higher-resolution images from other sources. WW allows the viewer to experience earth terrain in virtual-3D, with panning and zooming capabilities. NASA’s World Wind (WW) is a planet-visualisation globe that overlays satellite photographs, weather data, political boundaries and topological world maps.

This is a mapping/satellite imagery application that may be viewed in a simple web browser within a Windows operating system running. In response to Google Earth, Microsoft at the end of 2006 launched MSN Virtual Earth (VE) 3D within an Opensource API. Converting GIS files to KML, in combination with Google Sketchup drawing tools provides opportunities for file-based overlays. KML/KMZ is a XML data format that defines the viewing of information in Google’s virtual terrain.

This interface, made possible through AJAX technology, uses Keyhole Markup Language (KML) or its zip version (KMZ), as a standard for external data sources. The popularity of GE, the most downloaded viewer in the world, relies on its smooth interface and streaming for dynamic geo-visualisation. Google Earth (GE) contains high-resolution satellite and airborne images streamed via a dynamic internet desktop 3D-virtual-globe. Google Earth, MSN Virtual Earth 3D and NASA’s World Wind are standard 3D-Earth viewers with differing properties. RWS is currently publishing geo-information via Geoservices, but might certain characteristics of popular 3D-Earth viewers suit them to replace Geoservices? A geo-information infrastructure referred to as Geoservices and based on OGC Services Architecture has been established for this purpose. The strategy for meeting this challenge is built on principles of uniform working models, open standards, server-based computing and central data hosting and maintenance. It wants to considerably reduce ICT costs. Rijkswaterstaat (RWS) is the government organisation responsible for maintaining and administering main roads and waterways in the Netherlands. While Google Earth proves technically superior, other aspects must also be considered. Each is combined with Open Geospatial Consortium (OGC) Services to examine their performance in disseminating geo-information to the general public. How might this rapid development support steady, long-term development of institutions such as Rijkswaterstaat, the roads and water regulatory authority of the Netherlands? The authors consider and compare three standard 3D-Earth viewers: Google Earth, MSN Virtual Earth 3D and NASA’s World Wind. A 3D-Earth viewer enables navigating through the virtual environment and can be easily downloaded from the internet.
