Abstract: Systems, apparatus, and methods according to one or more embodiments are provided for encoding assistance data in locations technologies. In an embodiment, a method includes reading, by a processor, tile data of a database in a specific order, wherein the tile data comprises one or more reference data points and/or one or more empty spaces. The method also includes compressing, by the processor, the tile data based on the specific order using encoding. And the method further includes generating relative positions for each individual reference data point with respect to each other in the compressed tile data without specific location identification information for each reference data point.
