What is ECW?
The enhanced compression wavelet (ECW) file format is a high-performance image-compression format designed specifically for geospatial imagery. When compared to other image-compression formats, Intergraph’s patented ECW technology provides the fastest decompression and compression rates in the industry. 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.
