Tiling of GIS Data

Grids

Tiled data are a rasterized representation of the data. Which preserve all the styling from the exporting system. Vector data is much smaller dataset than the rasterized data. On average an additional layer (zoom level) of data will increase the size of the data by 400%! So rasterized data can be expensive.
