"Interpolate to fill small gaps in data" -method

Hi all,

I have a few topo-bathy lidar datasets all referenced the same that I am merging together in Global Mapper. Due to the dynamic nature of the nearshore environment, the datasets are not perfectly lined, resulting in a some gaps in the data. I used the "interpolate to fill small gaps in data" when exporting the various datasets to one, cohesive topo-bathy grid.

What does global mapper use for an intepolation method to fill these gaps? 

Thanks in advanced.
