run-length encodingA data compression technique for storing raster or gridded data. Run-length encoding stores data by row.
Run-length encoding is a format in which "along each row, only changes between attributes and the numbers of pixels of that same attribute are stored'(Clarke 1997, 83).
Run-length encoding - A method of data compression by replacing repeated sequences of values with a single value and a multiplier, e.g. 333333333333444422222 becomes (12)3(4)4(5)2 when stored as a run-length code.

Examples of compression methods include quadtrees, run-length encoding, and wavelets.
[ESRI software] A process that removes unreferenced rows from geodatabase system tables and user delta tables.
It involves arranging the image components in a "zigzag" order employing run-length encoding (RLE) algorithm that groups similar frequencies together, inserting length coding zeros, and then using Huffman coding on what is left.
space, bandwidth, cost, transmission, generating time, and the storage of data. These techniques are designed for the elimination of repetition, removal of irrelevancies, and the employment of special coding techniques, such as run-length encoding.
Another popular one is Voxel terrain which is generally used in games and simulations. Most commonly, this "voxel" terrain is actually stored and processed as a heightmap, the result of run-length encoding on a voxel grid.
geographic information, such as arc-node (topologically related vectors), CAD, raster, database records, or linked objects.
data format refers to the specific protocol or procedure used to store and manage geodata, such as GRASS run-length encoding ...
