WebBased Ltd. serves the world’s largest image over the Internet

WebBased Ltd, utilizing their Internet based GIS application InfoMapper and ER Mapper’s Image Web Server, is serving the world’s largest image, a 3.9 terabyte ECW file. The image of the South West of England is being served via the Internet to schools in England’s South West Grid for Learning. WebBased is ER Mapper’s leading partner in the provision of on-line Educational software.

Students use the image across the learning curriculum. The InfoMapper application makes it possible for the user to draw over any area of the image and attach or link to information and digital resources about that area.

UKP, Britain’s largest aerial photography data supplier, were commissioned to create the 3.9 Terabyte (3,900 gigabytes) ECW image. The image was comprised of over 24,000 individual 1km tiles of aerial photography. The tiles had a mixture of 10cm and 25cm resolutions. The ER Mapper application was used to mosaic the entire dataset into one seamless ECW image. The image is served using InfoMapper powered by ER Mapper’s award winning Image Web Server technology. Image Web Server is a high-performance application that serves ECW and JPEG 2000 images of any size to unlimited numbers of concurrent users.
