The linear referencing (LR) function for GeoPinpoint Suite allows the user to identify a single event at a geographic location between 2 intersections. Point event information includes the following:
- The distance (m) to the address point from the end of the segment (FromDistance)
- The distance (m) to the address point from the beginning of the segment (ToDistance)
- The nearest street from the start of the segment (IntersectedStartStreet)
- The nearest street from the end of the segment (IntersectedEndStreet)
Example Input address record - 2 intersection output
20 BAY ST, TORONTO, ON
fromDistance : 69.859808959243
toDistance : 48.364483125721
IntersectedStartStreet : QUEENS QUAY W
IntersectedEndStreet : HARBOUR ST
"35 ABBEYDALE VILLA NE","CALGARY","AB","T2A 7P6"
fromDistance : 66.834017036410
toDistance : 0.00000000000000
IntersectedStartStreet : ABBEYDALE DR NE
IntersectedEndStreet :

For situations that occur where a street does not intersect any other streets for a few segments (>3) – the linear referencing function will only search 3 segments in each direction in an attempt to find an intersecting street. Therefore, it is possible that an intersection may not be returned.
