Encoding and decoding of data

A method comprising at an apparatus:

• receiving or retrieving run-length encoded data in a sequence of records, wherein the data are associate to grid points of a grid and wherein data, which are associated to a same grid point of the grid and which represent pieces of information of at least two different types, are embedded in a same record of the sequence of records;
• and
• run-length decoding the data to obtain decoded data and an association of the decoded data to the grid points of the grid.

An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause an apparatus at least to perform:

• run-length encode data, which are associate to grid points of a grid, to obtain a sequence of records, the records being defined such that they allow embedding data associated to a same grid point and representing pieces of information of at least two different types in a same record;
• and
• cause at least one of storage and transmission of the encoded data.
