What are database Lines/Groups?
Geosoft databases are organized in lines, channels and elements. The database stores all data "elements" of a particular type in individual "channels" (or columns). Database "lines" are a collection of related "channels".
Each database "line" has a line number, version number, line type, flight number (only required for airborne data), survey date and selection status.
A "group" is a special kind of line. It also stores data in channels, but instead of using a name based on line number, version number, line type and flight number, it can be named using any alpha-numeric string (with some exceptions).
