Dear All, As of Jan 26, 2002 the new version 2.1 of the OrthoWarp ER satellite image orthorectification software is available for downloading at http://www.xposition.fi/pub/owarp/
Main changes: 1. Improvements of the satellite sensor model to better handle also higher level products with the sensor having large pitch and roll angles. This improvement is significant especially in high resolution data, such as Ikonos, on areas with high elevation differences. 2. It is now possible to import Ikonos & Landsat 7 multiresolution data also without original header information. Just make an algorithm or virtual dataset of all the files and import that into OrthoWarp ER. This gives the opportunity to have the individual bands ecw-compressed. But it is still recommended to use the original header and data files. 3. Added support for additional format (HDF and Fast format) variations and naming conventions (including ACRES) of Landsat 7 4. Added support for variations of level 2A of Spot images 5. Added support for additional variations of Ikonos data 6. Added support for more datums 7. Fixed bugs in gcp-import 8. Upgraded installation software 9. Some minor bug fixes. Especially the improvement mentioned in the first point is very significant when using Ikonos and Spot data, where the accuracies with the new version are in some cases notably higher than before. We recommend to update all the current production and evaluation versions to the new OrthoWarp ER version 2.1.
