What is a .mrsid file?

The MrSID (Multi-Resolution Seamless Image Database) file format is a proprietary geospatial imagery format developed by LizardTech (now part of Extensis). It is designed for efficient storage, retrieval, and manipulation of very large raster images, particularly aerial and satellite imagery, maps, and scanned documents. MrSID files employ wavelet compression, which allows for high compression ratios while maintaining good image quality. This compression technique enables fast access to different resolutions of the image without needing to load the entire file into memory. This is particularly useful for applications like GIS (Geographic Information Systems) and remote sensing, where users often need to zoom in and out of large images quickly. The format supports georeferencing information, allowing the image to be accurately positioned within a geographic coordinate system. MrSID files are often used in applications where large image datasets need to be efficiently managed and displayed, such as urban planning, environmental monitoring, and disaster response.
