GEOPAK-GEOTECHNICAL

Hello,

I am using Geopak v8i SS2.

I am importing borehole information using the Borehole Navigator by selecting Geopak->Road->Utilities->Geotechnical->select File in Borehole Navigator->select Import->select CSV->and import BRH, MTL and SPT csv files.  In populating the csv files, using the Geopak accepted column headers, I have several questions about the specific column headers and what they mean.  I have found what the headers are supposed to be in the help menu but not a detailed description. One example of a question would be "type_of_elev"; is that the top, bottom of soil layer or something else entirely?  

Thanks in advance for any suggestions.
