web maps are made up of many small square images called tiles

# quick review
1 tile = 256x256px
number of tiles at zoom level(z) = 4<sup>z</sup>
???
these tiles are typlically 256x256 pixels and are placed
side-by-side in order to create the illusion of a very large seamless image
thanks @mapbox!
each zoom level has its own set of tiles to keep a high resolution map
