An MRR dataset is stored in a single data file containing all raster data and metadata. The underlying storage format uses 64-bit file structures, thus enabling you to create a raster datasets of unlimited size. An MRR dataset is a valid raster format organized into fields and bands. Each field contains one or more bands and each band contains an array of pixels (cells). Each pixel has a value representing the geographic data.
The MRR data format is more capable than virtually any other raster dataset currently available and it introduces several new concepts in the raster data structure.
