VR-TheWorld Server Capabilities
Streaming Terrain for MAK ONE applications
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 that you can easily populate with your own custom source data through a web-based interface.

VR-TheWorld Streaming Terrain Server
MAK's VR-TheWorld Server is a powerful web-based streaming terrain server. 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. VR-TheWorld stores and streams feature data including roads, buildings, and trees to multiple applications simultaneously. We have continued 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.
In order to allow our customers to try out VR-TheWorld, we host a VR-TheWorld server on the internet that anyone can connect to if they have an application that supports WMS-C (including web applications), such as VR-Vantage or VR-Forces. 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
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. 30 m (DTED Level 2) for the entire globe, based on the SRTM V3 (SRTM Plus), merged with SRTM30Plus bathymetry. This is augmented with 25 m EU-DEM for Europe and many higher-resolution areas.
- Global imagery. Landsat 7 (15 m resolution for the entire globe) merged with NASA Blue Marble data (500 m resolution), color-corrected for seamless display, and pre-tiled to 7 mipmap levels.
- High-resolution inset areas. The insets range from 1 m to 15 cm per pixel – including southern CA, Boston, Seattle, Guam, and areas in Switzerland.
- Samples of topographic maps, Instrument Flight Rules (IFR) Enroute High and Low Altitude Charts, and Raster Nautical Charts (RNC) for the US.
- Global OpenStreetMap features in MBTiles format.
- High detail coverage for southern CA, with 10 m to 1 m elevation, 10 m bathymetry, 1 m to 15 cm imagery, and 15 m land cover.
- A highly detailed map of Hawaii, which includes:
- 15 m 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.
- 1 ft USGS Mosaicked Digital Orthophoto Quadrangles (MDOQs) produced through the National Digital Orthophoto Program (NDOP) for the island of Oahu.
- 1 ft water replacement imagery custom built by Harris, including Digital Globe WV2 Imagery blended into Oahu Imagery and Harris Terracolor Imagery to ease the transition between the 15 m and 1 ft imagery.
- 10 m Digital Elevation Model from USGS.
- 10 m bathymetry from the National Oceanic and Atmospheric Administration (NOAA).
- 2.5 m NOAA C-CAP Regional Land Cover.
- Feature data for Oahu, including building footprints for 230,000 buildings.
Add Your Own Data
VR-TheWorld Server comes with an intuitive web interface that makes uploading and organizing your data simple. The web interface walks 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.
VR-TheWorld Server Supports WMS-C
The server supports the industry standard WMS-C for streaming imagery and elevation data. This means that clients are not limited to MAK's visualization or simulation tools. Any customer or third party application that supports WMS-C (including web applications) can access VR-TheWorld Server immediately. (Of course, VR-Forces and VR-Vantage support VR-TheWorld.)
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 in Layers
In VR-TheWorldServer, data is organized in raster layers and feature layers. You can add and remove layers and specify the files that they contain.
