Shrink Big Data with Enhanced Compression Wavelet Technology
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 Compression?
Enhanced Compression Wavelet (ECW) is a high-performance image compression format developed by Hexagon, designed specifically for managing extremely large geospatial imagery datasets. By compressing imagery into a single, efficient file, ECW significantly reduces storage requirements while maintaining visual quality. It enables faster data transfer, smoother rendering and improved accessibility across devices and platforms.
Used globally for over 20 years, ECW continues to help organisations overcome the challenges of large-scale imagery by delivering speed, efficiency and flexibility across their workflows.
Designed specifically for large-scale geospatial imagery, supporting efficient storage and access across projects.
Achieves up to 15:1 compression ratios, reducing file sizes by up to 94% while maintaining visual quality.
Delivers industry-leading compression and decompression speeds, enabling quick access to large datasets.
Compatible with major GIS, image servers and storage platforms, ensuring seamless integration across systems.
Consolidate imagery into single large mosaics, eliminating the need for tiles, caches and multiple file versions.
High-Performance ECW Capabilities
ECW compression technology is built to handle the demands of large-scale geospatial imagery, combining speed, efficiency and visual quality. With advanced wavelet compression and optimised performance, it enables faster processing, seamless delivery and reliable access to even the largest datasets.
