    3. 3. Standardized production applications are the future of the eCognition Software. The first application in this space is an alternate GUI start-up mode for eCognition Developer 8 called QuickMap mode. Users can now start up the software in QuickMap facilitating the generation of fast solutions to standard mapping tasks. Experienced users will still find the full flexibility and power of eCognition in the rule set mode. Here we have put a lot of effort in the area of application building. New user interface components such as manual editing and reviewing tools now make building intuitive applications much easier. Geo Applications

    7. 7. New OBIA Dimensions With eCognition 8 we provide all algorithms and tools to facilitate working with LiDAR point clouds. This opens up a wide variety of applications such as object based LiDAR rasterization, feature extraction or LiDAR and Optical data fusion. New object reshaping algorithms allow generalization operations on objects. This can be applied to “squaring-up” buildings or fitting vegetation features into more organic shapes. We’ve also introduced a new concept called ‘multi-map functionality’ which has opened the door to a whole host of new possibilities. For the first time, &quot;true&quot; change detection can be offered within a geo-spatial image analysis platform.

    13. 13. Performance With ever increasing project size and data resolution, performance remains one crucial aspect of automated image analysis in eCognition 8. Performance was improved in two areas, image segmentation and data loading & browsing. Image segmentation was improved by optimizing the underlying algorithms resulting in a performance increase of up to 40% over version 7. In addition the new multi threshold segmentation algorithm was implemented, making generation of basic objects possible within a matter of seconds. Loading and browsing of data is improved by implementing an image proxy server, which automatically generates and stores image pyramid layers. This way projects will display up to 8 times as fast as in version 7. Browsing could be accelerated up to a factor of 6.

    15. 15. How Will You Get eCognition 8 ? (and other frequently asked questions)
    16. 16. FAQ <ul><li>Q: How will I get eCognition 8? </li></ul><ul><li>A: All users with a maintenance contract valid on November 1 st 2009 are entitled to eCognition 8 at no charge. The eCognition license team automatically sent out licenses for all eligible customers via email. eCognition 8 is available for download since November 1 st </li></ul><ul><li>Q: Will eCognition Developer 7 still run if I install eCognition 8? </li></ul><ul><li>A: eCognition Developer 7 will also run on the new eCognition 8 license. Hence you can switch between version 7 and 8 any time. </li></ul><ul><li>Q: Will eCognition Developer 7 rule sets run on eCognition 8? </li></ul><ul><li>A: eCognition 8 is downward compatible, this means you can run all Developer 7 rule sets. eCognition 8 rule sets will not work on Developer 7, however. </li></ul><ul><li>Q: Is there a trial version for eCognition 8 </li></ul><ul><li>A: Yes, you can find the trial version at </li></ul><ul><li>Note: *eCognition® Server is not included with trial software download package. eCognition Developer trial version allows non time limited full software access with the following restrictions: Disabled, in this demo: export functions, saving of rule sets, workspace environment. Projects saved in the trial version cannot be opened in a fully-licensed version of eCognition Developer. </li></ul>
