NASA World Wind Server to Leverage MapServer Open Source Engine

The NASA World Wind project team has selected the MapServer Open Source mapping engine to serve its many digital raster formats to World Wind clients. MapServer will serve images and raw data through the Internet by various Open Geospatial Consortium (OGC) standards. Providing large amounts of spatial data (including world-wide coverage of digital elevation models, DEMs, and aerial imagery) to World Wind clients requires a high performance architecture that will now use the MapServer engine, caching of images, and load-balanced servers. Technical expertise for MapServer will be provided by Mapgears (Chicoutimi, QC) and Gateway Geomatics (Lunenburg, NS). Due to MapServer compliance with
OGC standards and World Wind Server standards, except for possibly the increased performance provided by MapServer, this transition will be entirely transparent to the World Wind user community.
“MapServer will allow the NASA World Wind a smooth transition to a mature Open Source engine,” said Patrick Hogan, the NASA Project Manager of World Wind.
Daniel Morissette, President of Mapgears, added “We are thrilled to have this opportunity to work with the NASA World Wind team to help push the limits of the technology and to contribute with MapServer to the next generation of NASA World Wind Servers that will deliver the data of organizations around the world for years to come.”
Jeff McKenna, Director of Gateway Geomatics, said “Our long-time focus on assisting organizations publish their spatial data through MapServer, especially on the Windows platform, adds a key piece of an innovative solution with the Mapgears team. Together we will help to allow the World Wind community to visualize and analyze large amounts of data efficiently through MapServer.” Jeff also believes that this project will help both the MapServer and World Wind communities grow.

About NASA World Wind
NASA World Wind ( is a three-dimensional geographic information system developed by the National Aeronautics & Space Administration (NASA), its partners, and the Open Source
community. The World Wind client is an interactive 3D geographic visualization system, where Earth and other planets can be explored in their full 3D native context. World Wind was released as Open Source in
August 2004, and is being extensively used by corporations and government agencies throughout the world.

About Mapgears
Members of Mapgears” ( team have been active for over a decade in the development of the MapServer Web mapping engine and related open source technologies of the Open Source Geospatial Foundation (OSGeo). Mapgears offers professional, yet personalized services to assist application developers and integrators who made the choice of MapServer and other OSGeo technologies such as PostGIS, GDAL/OGR, OpenLayers, GeoExt and GeoPrisma.

About Gateway Geomatics
Gateway Geomatics ( is an innovative company on the East coast of Canada, assisting organizations publish their spatial information openly, through MapServer. With the hugely popular MapServer for Windows (MS4W) suite, developed and maintained by Gateway, organizations of all sizes can quickly share their spatial information on their own servers. The director of Gateway Geomatics, Jeff McKenna, also focuses on the user-side of Web mapping, and offers hands-on training with the MapServer project all around the world
