WebWhen storing data in a geodatabase, compression occurs before storage in the geodatabase. File and enterprise geodatabases only support LZ77, JPEG, JPEG2000, and NONE compression types. JPEG compression only works for unsigned 8-bit raster data and unsigned 12-bit data (stored as 16-bit data). In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information. Typically, a device that performs data com…
