VR-TheWorld Server: Streaming Terrain
Streaming Terrain for Modeling & Simulation
VR-TheWorld Server is a powerful web-based streaming terrain server that lets you stream in elevation, features, and imagery. It is delivered with a global base map, but you can also easily populate it with your own custom source data through a web-based interface. The server can be deployed on private networks to provide streaming terrain data to a variety of simulation and visualization applications behind your firewall.
A World of Data
VR-TheWorld stores and streams elevation, imagery, and features including roads, buildings, and trees to multiple applications simultaneously. We continue to expand the amount and quality of imagery and elevation data included with the server while also allowing you to add your own geospatial data to distribute in real-time. VR-TheWorld Server is seeded with over 2 Terabytes of global elevation and imagery data — pre-tiled for high performance access. Have a look at VR-TheWorld Server hosted on Amazon.

VR-TheWorld Online - A Taste of VR-TheWorld Server
In order to allow our customers to try out VR-TheWorld, we are hosting a VR-TheWorld server on the internet that anyone can connect to. This server shares some common maps and allows you to get the feel for what it is like using a streaming terrain server. It does not allow you to upload your own content.
VR-TheWorld Server is Ready Out-of-the-Box (Literally)
The VR-TheWorld Server installation is a 1U rackmount chassis that houses the server and raid array. The hardware comes pre-installed and ready to go out of the box. A VR-TheWorld Server is a fully standalone version of VR-TheWorld and can be deployed behind firewalls and security barriers.
VR-TheWorld has over three terabytes of global elevation, imagery, and feature data — pre-tiled for high performance access. The VR-TheWorld Basemap has:
- Global elevation. 90-meter (DTED Level 1) for the entire globe, based on the CGIAR-CSI version of NASA's SRTM30 dataset, merged with SRTM30Plus bathymetry.
- Global imagery. Landsat 7 (15m resolution for the entire globe) merged with NASA Blue Marble data (500m resolution), color-corrected for seamless display, and pre-tiled to 7 mipmap levels.
- High-resolution inset areas. The insets range from 1m to 15cm per pixel – including Boston, Washington, D. C., and two airport areas in Afghanistan.
- Samples of 1:250,000 and 1:100,000 topographic maps in Southern California.
- A highly detailed map of Hawaii, which includes:
- 15m Harris Terracolor imagery, added to make the area surrounding the Hawaiian Islands look more like deep blue water. This product has a very nice view of the shallow water boundaries between the ocean and the islands.
- 1ft USGS Mosaicked Digital Orthophoto Quadrangles (MDOQs) produced through the National Digital Orthophoto Program (NDOP) for the island of Oahu.
- 1ft water replacement imagery custom built by Harris, includes Digital Globe WV2 Imagery blended into Oahu Imagery and Harris Terracolor Imagery to ease the transition between the 15m and 1ft imagery.
- 10m Digital Elevation Model from USGS.
- Feature data for Oahu, including building footprints for 120,000 buildings.
Add Your Own Data
VR-TheWorld comes with an intuitive web interface that makes uploading and organizing your data simple. The server ships with a 6 TB raid array that has about 3 TB taken up with the initial dataset. The rest of the space is ready for you to add your own data. The web interface will walk you through uploading your data and creating new layers from the data. Everything you need to do to have your own data serving from VR-TheWorld can be done right from the web interface.
Supported Data Formats
VR-TheWorld supports the following raster file formats:
- GDAL virtual
- JPEG 2000
- DTED 0 - 5
- Arcinfo Binary Grid
- Magellan BLX Topo
- Bathymetry Attributed Grid
- VTP Binary terrain format
- USGS DOQ
- ESRI .hdr
- Envisat Image Product
- Erdas Imagine
- National Imagery Transport Files (CIB, CADRG, and so on)
- BSB Nautical chart format
VR-TheWorld supports the following vector file formats:
For performance reasons, VR-TheWorld Server serves out PNG, TIFF, and JPEG. PNG provides lossless compression of image data and transparency. JPEG provides high level of compression but no transparency. JPEG is recommended for large base layers where transparency is not required. TIFF does not provide compression but supports transparency. TIFF's are recommended for elevation data layers.
VR-TheWorld Serves Feature Data
Features are served using the industry standard WFS protocol.
Integrate Local Data with Served Data
VR-TheWorld customers may want to integrate locally stored data with data served from VR-TheWorld. You could, of course, upload the local data to the server. However, this might not be practical due to the amount of data, for security considerations, or other reasons.
You can integrate local and remote data if your application supports the osgEarth earth file format. Create an earth file for the local data and merge it with the earth file for the served data. When you load the earth file in your application, it will grab the data from all the locations specified in the file.
VR-TheWorld supports Mozilla FireFox, Microsoft Internet Explorer, Google Chrome, and Apple Safari. No other browsers have been tested. The VR-TheWorld software uses Adobe Flash for uploading files.
VR-TheWorld Server Supports Many Connection Protocols
The server supports the industry standards TMS and WMS-C for streaming imagery and elevation data. This means that clients are not limited to VR-TheWorld's visualization or simulation tools. Any customer or third party application that supports WMS-C or TMS (including web applications) can access VR-TheWorld Server immediately. (Of course, VR-Forces and VR-Vantage support VR-TheWorld.)
VR-TheWorld also supports Google Earth by being able to generate KML files that ease setting up connections. NASA Whirlwind can connect out of the box as well. Some tools may need additional plugins to support the protocols, for example ESRI ArcMAP can use the ArcBruTile plug-in to show VR-TheWorld Imagery.
VR-TheWorld Server Provides Management Tools
The VR-theWorld Server administration interface provides the tools you need to upload and organize your data.
VR-TheWorld can display information about the files in the database, such as the filename, pathname, type, size, and so on.
Data is Organized into Maps
The data in VR-TheWorld is organized into maps. Each map has one or more layers. A layer is made from one or more files that contain image, elevation, or feature data. If you view the data in the web interface, it tells you what layers are in each map. If you have administrative authority, you can create, edit, and delete layers and maps for use by VR-TheWorld.
Administrators Can Add Placemarks to Maps
Map administrators can put placemarks on a map. Placemarks allow you to quickly zoom in to the location that is marked.
Change the Transparency of a Layer
Layers are placed on top of each other, or at least on top of some base layer of imagery. If you want to see what is beneath a layer, you can change its transparency. By making the base layer transparent, you can easily find out where other layers are located.
shows the Hawaii map with the Honolulu Water Imagery layer fully visible and mostly transparent.
VR-TheWorld Server Provides Connection URLs
You can connect to the server using TMS or WMS. These connections are on a per layer basis. VR-TheWorld provides a URL with appropriate connection data.
