GetStreetLocation()

Gets a description of the street location of a coordinate.

desc = GetStreetLocation(string street_field_spec, coord c, double threshold)

Argument	Contents
street_field_spec	The field spec for the string column containing the names of the streets
c	The search coordinate
threshold	The threshold, in current map units, which determines whether the coordinate is at an intersection

The description as a string. The string returned can be one of the following formats:

street_field_spec must be a field spec with the format LayerName.FieldName.
The street layer must be a standard (.dbd) or compact (.cdf) line geographic file.
The street layer and the corresponding intersection node layer must be in the current map.
The distance threshold determines whether the output string includes the phrase "Street1 & Street2" or "Street1 near Street2".

// Before running the example, create a map by opening manhastr.cdf

// in the Tutorial folder.

SetLayer("Street")

c=Coord(-73845917, 40807680)

// Assumes current map units are miles

loc=GetStreetLocation("Street.NAME", c, 0.002)
