After successfully generating tiles, a series of folder directory structures will be created under the user-specified tile storage path. This document takes image tiles as an example for explanation. The image tile directory is divided into five levels. The following sections provide detailed analysis of the image tile directory structure establishment.

  First Level of Tile Directory: Tile Root Directory

  Second Level of Tile Directory: Tile Layer Directory

  Third Level of Tile Directory: Row Folder

  Fourth Level of Tile Directory: Column Folder

  Fifth Level of Tile Directory: Tile File

  Foundation for Other Level Structure Construction
