The Multiresolution Seamless Image Database (MRDB) format is a specialized file format designed for storing and managing large, high-resolution images that can be seamlessly viewed and navigated at different zoom levels. It's particularly useful for applications like geographic information systems (GIS), medical imaging, and large-scale art repositories where users need to explore detailed imagery without downloading the entire file at once. The MRDB format typically involves tiling the original image into smaller, manageable pieces and creating multiple resolutions of these tiles. This allows software to efficiently load only the tiles necessary for the current view and zoom level, significantly improving performance and reducing bandwidth consumption. The format often includes metadata describing the image's spatial properties, resolution levels, and tiling structure. While not as widely supported as common image formats like JPEG or PNG, MRDB offers significant advantages for specific applications dealing with very large, detailed images that require efficient viewing and navigation.
