ENVI can be considered as a collection of toolboxes or functional components including: This has resulted in a user interface for this product that not only delivers on providing a simpler user interface with automation, but one that is logical in its layout and functionality. The new workflow efficiencies will not only please experienced users, but will allow any level of user to perform advanced techniques.РІР‚Сњ ENVI 4.4 really provides over-arching capabilities to make the latest image processing technology readily available to anyone. In speaking with Richard Cooke, COO and President, ITT Visual Information Solutions I inquired about ease of use, to which he said, РІР‚СљWe wanted this release to be focused primarily on efficiency and automation РІР‚вЂњ making image processing and analysis workflows easier and faster. 1), while also including user feedback from geospatial professionals and image analysis specialists in terms work flow demands. ENVI 4.4 has refined and incorporates these tools, providing greater ease-of-use (see Fig.

For software companies, the task has to been to deliver on these demands and development of tools with increasing levels of automation and ease-of-use has been the result. To meet these challenges users have been demanding all the strengths of image analysis algorithms and functionality, while at the same time asking for them to be delivered through more easy-to-use interfaces. This ultimately results in higher value from the data and technology. Therefore, a federated approach, which involves many technologies, data types and sources, are all contributing toward greater challenges for integrating this information. Many professionals involved in image analysis and processing must integrate image intelligence with other geo-technologies such as geographic information systems (GIS), global positioning systems (GPS) data, laser point cloud data, surveying and spatial information acquired through alternate technologies and sources, more quickly. Improved technology, application requirements and demands, have also contributed to growth and change. During this evolution, user needs have grown and expanded. A new interoperable National Imagery Transmission Format (NITF) imagery format for enhanced data fusion is also included.Р”В®NVI 4.4 builds on a history of excellence in software design and function for processing airborne images useful for geospatial purposes. This version incorporates significant additions and benefits over previous versions due to its ability to work with a new ENVI Feature Extraction Module, Atmospheric Tools (FLAASH) and Digital Elevation Module (DEM) extraction. It is a complete image-processing system that includes spectral tools, geometric correction, terrain analysis and radar analysis while also incorporating strong GIS functionality for working with both raster and vector data. ENVI 4.4 is the latest edition of this popular image processing software from ITT Visual Information Solutions and builds upon the previous versions of this product.
