Stake-out alignments functions in Triumph LS allow
to perform stake-out of simple roads or linear features
with or without cross-sections based on projects de-
signed beforehand. The system provides for keying in
prepared data, doing simple editing, previewing the
entered project and performing actual stake out.
Alignments are always specified in projected or local
CRS (that is, “in meters/feet”).
Data Model
An alignment consists of the following elements:
Horizontal Alignment — definition of the alignment
centerline (a curve) in horizontal plane, setting corre-
spondence between station value (length along the
curve) and (northing, easting) coordinates. The hor-
izontal alignment has definite start (not necessarily
zero) and end station values, and beyond these end-
points is implicitly extended by straight lines tangent
to the curve at endpoints (Figure 1).
