Voxler imports ERMapper .ECW files.
Enhanced Compression Wavelet .ECW is an open standard wavelet compression image format developed by Earth Resource Mapping. The file format is optimized for aerial and satellite imagery, and efficiently compresses very large images with fine, alternating contrast. This is a lossy compression format. A region can be specified for import in the .ECW Image Import Options dialog, or the image can be imported as a read-only image. Each of these options decreases the import time for large ECW files.
The .ECW file format has the following properties:
Embeds map projection information
Fast compression (about 1.5 MB of compressed file per second on 1 GHz processor)
Typical compression ratios between 1:10 and 1:100
Possible decompression of selected regions without the need to decompress the whole file
Data flow compression allows for compression of big files with small RAM requirements
