iii.

Marker 1 step:

this field represents the distance between two

reference lines marked on the site. The default value is 10 m. This

function allows you to realign the radar sections to compensate for

any distance variations with respect to the data acquired with the

position sensor wheel. This realignment is performed according to

the value set in the

Marker 1 step box

. This setting is typically

used for realigning longitudinal scans. If you set the marker with a

specific position and then press the button shown in Fig. 4-29,

contained in the window shown in Fig. 4-31 at a distance of

20%

either before or after this assigned point, the

Pos. Marker

will be

transformed into a

User Marker

when the file is saved (see Fig.

4-31 and point 3 of Par. 4.6).

iv.

Longitudinal/Transversal – Inverse direction:

this field allows

you to select the scanning direction of the radar section about to be

acquired. When filling in this field, remember that

Longitudinal

(

)

means the scans is performed parallel to the zero reference line (T

axis), while a scan perpendicular to this line is called a

Transversal

scan

(

) (see Appendix A). The

Inverse direction

field allows you

to perform a T/L scan in the opposite direction, i.e., moving in a
