Cross-Street Distance Dataset

Callpoint Spatial’s Cross-Street Distances dataset provides details of the nearest cross-streets for each geocoded G-NAF address record.

The dataset is generated by Callpoint Spatial’s production system using PSMA Transport & Topography® and G-NAF.  Some caveats apply.

The Cross-Street Distances (“XSD”) dataset finds application in the infrastructure and logistics sectors.

Cross-Street Distance Example

Please refer key columns below.

Above: results table for a section of Clare St, New Town TAS between Honora Ave and Fraser St.
For each G-NAF address and associated PID, the other columns and terms have the following meaning:
‘Nearest Cross Street’ indicates the nearest intersecting street to the GNAF street (the GNAF street being Clare St in this example)
‘Distance to Nearest Cross Street’ indicates the ‘along street centreline’ distance (in metres) from the Landing Point to the Street Intersection
‘Landing Point’ represents the point on Clare St where an imaginary line from the GNAF address point intersects it
‘Street Intersection’ is defined in our Street Intersection dataset

The maps below are a little involved. Please review in conjunction with the legend below each map.

Above: section of Clare St New Town TAS to facilitate understanding of the previous table.
Dark crimson dots: GNAF address points
Green dots: Cross-Street Distance Landing Points showing distance to nearest cross street (metres)
Light blue polylines: PSMA Transport & Topography roads layer
Light grey polygons: PSMA Cadlite cadastre layer
Purple Star: Callpoint Spatial Street Intersections

The map below provides a little more detail.  The label for each green dot also shows the name of the cross street to which it is closest.

Data Model

The data model is shown below.  Table columns include the names of the nearest cross-streets and “along street centreline” distance to the nearest cross-streets.
