Process for importing landscape from csv to UE


I’m looking to understand how I can take a bathymetric (ocean topography) .csv file with latitude, longitude, and elevation columns and import it as a map in UE4. I’ve done a lot of searching but haven’t come up with a great way to do this. I see a lot of folks using heightmaps but those are not available with my datasets. Is it necessary to use a height map? Is there a way to perform a conversion?

I apologize in advance if this has been covered elsewhere. Any help is appreciated!
