FME can read data in the Esri Tile Package (TPKX) format.
This format contains raster tiles stored using the Esri Compact Cache V2 specification and provides enhanced performance when accessing tiles, especially when dealing with network file shares and cloud storage.
The Esri Tile Package (TPKX) is a compressed archive file. The contents of a TPKX archive have the following structure:
-
The metadata (root.json) describing various properties that are required to visualize the cache.
-
The metadata (iteminfo.json) describing the various properties needed to identify and preview the item without loading all of its contents.
-
A thumbnail image.
-
A tile directory containing the cached tile data stored in the Compact Cache V2 format at various Levels of Detail (LOD).

Reader Overview
The reader processes data from both local and remote .tpkx files, containing raster tiles stored using the Esri Compact Cache V2 storage.
FME considers a single TPKX file to be a dataset and prefers files with the .tpkx extension. The file must contain the JSON metadata as well as the tile directory containing the cached tiles to be valid for reading with the Esri Tile Package reader.
Users can select subsets of data based on a spatial envelope as well as specify a specific Level of Detail (LOD) to read the dataset with.
FME Raster Features
FME raster features represent raster data and use several concepts that are unlike those used in the handling of vector data.
For comprehensive information about how FME processes raster data, see Rasters.
Esri .hdr supports rasters with an arbitrary number of bands, provided all bands are the same data type and no band has a palette. Esri .hdr also supports rasters with a single band that has a palette.
For each raster, there is only a single feature returned, since this feature will contain the entire raster.
