VNS 2 supports open standard technology

1 August 2003

GIS-based terrain visualisation professionals around the world can now have fast and efficient access to huge gigabyte and terabyte high-resolution spatial imagery datasets with Visual Nature Studio 2 (VNS 2).
VNS 2 now supports Earth Resource Mapping's open standard enhanced compression wavelet (ECW) technology. VNS 2 allows for the dynamic demand-paged loading of ECW files to efficiently access only the required data in a large image.
"What this means is, if you are visualising a site and have an image mosaic of the entire region, you no longer need to crop and georeference a subset of your image. Just provide VNS 2 with your ECW file, and it will efficiently use the areas you need coverage for without using excessive memory or requiring laborious cropping or preprocessing. Being able to immediately use massive, off the shelf image mosaics greatly speeds the visualisation process," said Chris Hanson, vice president of Research and Development for 3D Nature.
VNS2 automatically reads georeferencing metadata from ECW files, using VNS 2's dynamic reprojection for automatic alignment of imagery with other DEM raster and vector data. VNS 2 can also save raster output visualisations to the ECW format, complete with georeferencing for use in other GIS and imagery applications.
VNS 2 can also access ECW through ER Mapper's Image Web Server. Image Web Server streams the image into VNS 2, providing only the data needed to satisfy the visualisation requirements. This results in lower network and server loads when dealing with large images. Visualisation professionals will also be able to access massive libraries of Web-based image datasets. Visual Nature Studio 2 is currently available for Windows and Macintosh. VNS 2 is used worldwide for terrain visualisation in architecture, GIS, forestry, land planning, civil engineering, golf course design, aerospace, television, feature films, game development and publishing.
