Offline WMTS map Best practice for cesium

Cesium for Unity

Hi,
I need to load a WMTS map while offline, what is the best way to approach this issue?
Can Cesium load a GPKG or TIFF file directly?

Thanks. Is it on the Cesium roadmap?

We don’t have any immediate plans for direct Geopackage or GeoTIFF support. It probably wouldn’t be too difficult to add a RasterOverlay to support these though, and we’d certainly welcome a pull request if you’re up for it!

Otherwise, the easiest workaround is to upload to Geopackage or GeoTIFF to Cesium ion, which will tile it for you. You will then be able to download it for offline use. See here:

That will give you a ZIP file. Extract it to a directory, and then load it in Cesium for Unreal using the CesiumTileMapServiceRasterOverlay component and a file:/// URL pointing to the tilemapresource.xml file.
