Point Angle and Position Wizard

Identifies the closest polyline from the reference layer to each point and calculates: the angle of the closest polyline segment, the position & stationing of the point along the polyline and the distance to the polyline

Inputs:

Point feature layer
Reference polyline layer
Search tolerance - the maximum distance to search for features in the distance layer

Outputs:

A new Point feature class. The attribute table of the resulting feature class will have three new fields
- [ET_Angle] - the angle of the closest segment of the closest to the point polyline. The angle is in degrees 0.00 = North, clockwise.
- [ET_Pos] - the distance from the start point of the closest polyline to the point along the polyline as a percentage of the total length of the polyline.
- [ET_Station] - the actual distance from the start point of the closest polyline to the point along the polyline, measured in the map units
- [ET_Dist] - the shortest distance from the point to the closest polyline measured in the map units
- [ET_Side] - indicates on which side of the polyline is the point (introduced in version 10.2).
- [ET_M]/[ET_Z] - the M(Z) value interpolated from the closest polyline (if the reference dataset is of PolylineM(Z) type)
- [ET_Closest] - the ID of the closest polyline from the reference dataset.

Notes:

If the distance from a point to the closest feature from the distance layer is larger than the Search Tolerance then the [ET_Angle] will have a value of 0, [ET_Pos] and [ET_Station] will have values of -1
The distances are calculated in the Spatial Reference of the input feature class
All the attributes of the input point dataset are transferred to the output
The function incorporates the functionality of the Point Distance and Measure Points functions available in the pre - 11.0 versions of ET GeoWizards.
