The adjoining figure illustrates the principle of positioning using reference data.
For this purpose a special correlation method is applied. The basic concept is to find the mathematically best fitting data segment of the import data inside reference data. (...)

The following combinable kinds of positioning are available in IRISSYS^®:
a) Assignment using track identifiers which includes positioning information like kilometre or mile
b) Assignment using data of positioning systems like GPS or GALILEO
c) Assignment using data of reference measurements (...)

This example shows object relations between: catenary poles, catenary segments and the track.

The integrated condition analysis includes all inspection and reconditioning data of every component of the permanent way. It is generally enabled through the introduction of object relations. (...)
