XYZ Data

An XYZ data file is a file containing at least three columns of data values. The first two columns are the X and Y coordinates for the data points (also know as "Easting" and "Northing" values respectively). The third column is the Z value assigned to the XY point. It is common to have multiple "Z" columns.
