nearFeature

Calculates the distance for each feature of the Input dataset to the closest feature from the Near dataset. In the attribute table of the output the distance is recorded together with the ID of the closest feature.

Inputs:

Input Dataset - Point, Multipoint, Polyline or Polygon
Near Dataset - Point, Multipoint, Polyline or Polygon
Search tolerance - the maximum distance to search for features in the near layer in the units of the spatial reference of the Input Dataset

Outputs:

New feature class. The attribute table of the resulting feature class will have three new fields

[ET_Dist] - the distance from the input feature to the closest feature from the near layer
[ET_Closest] - the ID of the closest feature from the near layer

Notes:

If the distance from an input feature to the closest feature from the distance layer is larger than the Search Tolerance then the [ET_Dist] and [ET_Closest] will have a value of -1
If an input feature intersects several features from the near dataset an arbitrary feature from the intersecting near features will be assigned as closest and the distance will be assigned to 0.
If the input layer and the near layer have different Spatial References the distance is calculated in the Spatial Reference of the data input dataset.
The spatial references of the Input and Near dataset must have the same geographic coordinate system.

Examples:

	Input Dataset - Polygons Near Dataset - Polylines
	Input Dataset - Polylines Near Dataset - Polygons
	Input Dataset - Points Near Dataset - Polylines
