Out-of-the-box Grome comes with 16bit RAW import of heightmaps. Any heightmap you have you can save to RAW (or convert it from other types of images like 16bit png). The importer also knows to break the imported raw into multiple zones if the user wants that and it can also use custom Grome swapping feature (present in Professional edition) to automatically swap out to disk zones as they are imported. So using this swap system you can import very big raw files that otherwise would not fit in memory.
The importer lets you specify the importing area size, height scaling and bias so you reproduce the exact terrain localization as the original. 16bit format will allow you to have a big range in the heightmap (as opposed to 8 bit images) so approximation errors are avoided.
Jpg images can also be imported as color layers in the Raw importer.
The inverse is also available (exporting to 16 bit raw) in the form of a default export plugin.
There is also a BT importer which, as the name implies, imports from BT format which is a well known elevation format (vterrain.org).
Grome also comes with a SDK so if you want more complex import schemes you can write your own custom plugin.
