ECW Compression
Shrink Big Data with Enhanced Compression Wavelet Technology (ECW)
When you compress your imagery into ECW format, the result is a much smaller single file that can be stored, sent, and displayed even on small devices. ECW technology provides exceptional compression, capable of reducing terabyte-sized files to five percent of their original size, while retaining the image’s full visual quality.
What is ECW?
Enhanced Compression Wavelet (ECW) is a proprietary format from Hexagon that for more than 20 years continues to solve the geospatial image big data challenge by offering greater speed, flexibility and compression savings than any other storage mechanism.
Why is ECW the ultimate format for your geospatial image archive?
- High-performance compressed file format designed specifically for extremely large imagery stores.
- Achieves 15:1 compression ratios (94% reduction).
- Fastest compression and decompression (rendering) rates in the industry.
- ECW file format is supported across all major image server and storage platforms.
- Improves workflows by consolidating imagery into large mosaics, rather than being forced to create smaller tiles, caches and other variants. Consolidate projects into 1x file and use it everywhere.
- Increased user satisfaction.
ECW Capabilities
Visually Lossless Compression
Wavelet compression algorithm achieves 15:1 compression ratios at a visually lossless quality level.
Fastest Compression and Decompression
ECW compression is at least 50% faster at compressing images than other compression techniques.
Fastest Compression and Decompression
ECW compression is at least 50% faster at compressing images than other compression techniques.
ECW for ArcGIS Server
With ECW support, ArcGIS Server users can leverage compression technology capable of quickly decompressing and opening massive files.
Get More Out of Your Imagery
Compress big imagery data by 95% while retaining full visual quality and serve with lightning fast speed from ArcGIS for Server. Using the Enhanced Compressed Wavelet (ECW) image format and ECW for ArcGIS for Server, you can provide users with the fastest image delivery and decompression rates available without cumbersome tile cache generation, ensuring imagery can be delivered as quickly and to as many users as possible.
