Off Bathymetric Information in cesium

I have used mapserver to created tiles of the world tiff file. But the world tiff file contains bathymetery data and on viewing the tiles on Cesium using new Cesium.CesiumTerrainProvider , the land is below the oceans, like in a trench. ( the land 3d works well )

Is there any way that I can disable the bathymetery from cesium end, like any flag or something?

My zoom level for tiles is only 9. If i do till 18 will it do justice and fix this issue?


I don’t think there is a way to modify the terrain as specified without changing the source data. Moreover, defining bathymetry can be challenging on a large scale. This is because we quickly encounter difficult questions like:

Is bathymetry terrain with height less than 0 or height less than the mean sea level? Should mean sea level be defined regionally? etc.

Let me know if you have any questions or concerns.
