ground line data

Ground-based line data is collected along relatively straight lines and roughly parallel lines. The survey lines normally have a line number that is related to the local coordinate system. Data readings can be taken anywhere along a line at identified station numbers, which are normally related to a ground coordinate system.

• If you are planning on adding more data to your database, we recommend creating a fiducial channel based on your station number data. This will enable you, for example, to import data at 50m and later import data at 25m into the same database.

When importing ground data, you can:

• Use station numbers as fiducials
• Use reading numbers as fiducials
