ECW is a proprietary Wavelet compression format optimized for aerial and satellite images developed by Earth Resource Mapping, but now owned by ERDAS. ECW file can hold data gathered with satellite or aerial cameras and georadars located in space.
ECW format is optimized for aerial and satellite imagery to meet the needs of geolocation and data mapping. Images in this format are used along with geospatial data.
Image data stored in ECW file are compressed using lossy compression algorithm without significant loss of image quality. This type of file is ideal for large-format pictures, because the ECW compression algoritm handles large images very well, reaching compression rations from 1:10 to 1:100 – result hard to achieve using other compression algorithms. ECW format supports from 1 to 8-bit continuous data per layer and up to 255 colors.
When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the ECW extension without any issue. However, if you still have problems with this, you may use the option of ECW file conversion to a different format.
We hope we helped you solve the problem with the ECW file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.
There can be more reasons which determine that you are not able to open the ECW file (apart from the lack of the proper application installed).
First - the ECW file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the ECW file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the ECW file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the ECW file has not been completed and it cannot be opened properly).
