What is ECW?
Enhanced compression wavelet (ECW) is a high-performance compressed file format designed specifically for geospatial imagery. When compared to other image compression formats, ERDAS’ patented ECW technology provides the industry’s fastest decompression and compression rates possible. Remarkably, this is done without placing a heavy load on computer memory and processors, while also maintaining high compression ratios and visually lossless image quality.
