Unless you are looking for Geodimeter file format compatibility, you should consider storing a section output file in the
“.SCT” format, since it can be converted, using Road Utilities, to LandXML form and then imported to several different
roading software packages for plotting and computation of volumes. The “.SCT” section files can also be used directly
for volume calculations with Carlson Roads, Leica Site Manager, Topcon Topsite and Carlson Civil. You can also set
the rounding—here, a rounding of 10 units (feet or meters) has been selected. The station and offset can also be stored
as the point description and as a note file, if the lower options are clicked on.
Note that the rounding is fully automatic. If you choose a 5-unit rounding, and are targeting station 0+75, but take a shot
at 0+77.93, it will round up to 0+80.
Before collecting the cross sections, it is important to click X-SCT Settings near the top of the dialog, and set the
stations you wish to capture. This way, if the station rounds, per the above screen, to a station that doesn’t exist in your
list, you are warned before proceeding with storing. This list also includes the left and right “tolerances” for the offsets,
which will lead to warnings if you exceed that distance from centerline. If you set a tighter “Station Tolerance” in
X-SCT Settings (option Edit) than the “Rounding” Tolerance, you will be warned even though the rounding is correct.
In the screen shown below, station 16+70.000 has been added as a special station. Clicking the first line
(10+00.000-23+00.000) allows you to set the standard interval, and the additional stations in the list would be for
special stations in addition to the standard interval.
The below, smaller dialog appears when you tap Add Odd Stations, shown in the above figure.
