.las elevations from lidar

I have exported a Lidar set, but the software I have does not let me configure the export. It exports the elevations in what appears to be distance from geoid or something like that. My elevations are -27.00 for southern Georgia. Can I use Global mapper to convert. I can bring the .las into global mapper, but I can not find an elevation option refering to geoid or anything like that. Please help.

    There are not yet any vertical datum/geoid conversions in Global Mapper. Unless you are very near the coast-line I wouldn't expect even most geoid conversions would result in anything in Georgia being at an elevation of -27. Do you know what geoid the data is supposedly in?

    Thanks,
