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.
#Nasa world wind vs google earth zip
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.
