ArcGIS tile migration refers to the process of converting tile data in ArcGIS format to the tile storage format supported by the SuperMap platform. Tile data serves as the base map for map services and plays a crucial role in GIS applications by enabling fast loading and smooth browsing. When users migrate from the ArcGIS platform to the SuperMap platform, the existing tile data resources need to be seamlessly transferred to avoid the time and computational costs associated with re-cutting tiles.

ArcGIS tile data primarily exists in two forms: one is packaged as offline tile bundles in .tpk files, which are convenient for distribution and transmission; the other is compact tile folders (V1/V2 format) generated when publishing map services, used for efficient server-side calls. The forwarding tools provided in this section can directly parse these two forms of tile data and convert them to local tile formats supported by SuperMap or MongoDB database tile formats, achieving smooth migration of tile resources.

SuperMap iDesktopX offers two tile forwarding tools to meet different storage and application needs:

• ArcGIS Tile to Local Tile: Converts ArcGIS tiles to SuperMap's local file-based tiles (compact or original format), suitable for tile invocation scenarios in standalone environments or file sharing methods.
• ArcGIS Tile to MongoDB Tiles: Directly writes ArcGIS tiles into the MongoDB database, converting them to database tile storage formats, suitable for scenarios requiring multi-user concurrent access, web-side publishing, or cluster deployment.
