5.3.5 Acquisition for mapping
Select the Edit Parameters button in the New Acquisition window to set the starting point
coordinates. Choose the following acquisition parameters.
The acquisition direction as either longitudinal or transversal. When filling in this field,
remember that Longitudinal (L) means the scans are performed parallel to the zero reference
line (T axis), while a scan perpendicular to this line is called a Transversal scan (T.)

Coordinate (m): This field allows you to insert the values of the set T or L coordinate.
Remember to indicate if a coordinate is negative. Check the current T or L coordinate on the
site and insert it into the relative field. Despite the actual dimensions of the antenna box, it is
represented in the Cartesian reference system by a single point that corresponds to its
centerpoint. When moving the antenna, make sure the centerpoint is on the scan line at the
defined coordinate.
¾ Coord. Value: insert the value of the coordinate to be maintained constant during
the scan in this field.
¾ Coord. Step: this field contains the step value that is add3d automatically to the
current value when a scan is finished, leaving the system ready to start the next
scan. The preset value =2 m between cans. For example, if a longitudinal scan has
been chosen and it starts from a point with coordinates T, L -0 ++ 2 m, the
following values must be set:
• Longitudinal;
• 2 in the Coord. Value field;
• 2 in the Coord. Step field.
Once the scan is finished, the coordinate of the L value is automatically positioned
on the value 4.
