Reducing Cesium Ion storage usage when working with GeoTIFFs

I currently have raster data in the form of RGB imagery geotiffs and DSM geotiffs. I would like to minimise the amount of data I store on Cesium Ion. I was thinking of using S3 but the amount of data stored on Cesium Ion does not seem to be reduced. I assume this is because of the data type. What format should my data be stored in on S3 so that only the tiled data is stored on Cesium Ion? How can I convert my geotiffs to this format?

Hi onish-ai

Currently Cesium ion is counting the source data size for storage for uploaded assets. If you are uploading the source from S3, the tile asset size is counted (since we are not storing the source). So the format you store the data in on S3 won’t have any impact.

Hopefully that answers your question. Please let us know if you still have other questions.

Hi mdc9001

Thanks for getting back to me! Does this mean that this article is no longer relevant with regards to storage usage? Tile Massive 3D Data on Cesium ion Directly from AWS S3 – Cesium

Hi,

No, that article is still relevant.

Tiling from S3 also cuts down on your ion storage costs because only the tiled data is stored in your account, which is significantly smaller than the source data in most cases. Normally, the file-size of the source data is what counts towards your storage quota.

While the tiled data can be smaller than the source it depends on the actual data. It could be that in your case there was not a significant reduction in file size between the tiled and source data.

Can you share more about your reasons for wanting to reduce your Cesium ion storage? That might help us recommend other solutions.
