spiderDiagramAttributeLink

Creates a Spider Diagram between the points of a Center Points dataset and the features in the destination layer (points, polygons, or polylines) based on the values in the link fields in both datasets. The created polylines will connect the Centers to the destination features if the values in the link fields are the same.

Inputs:

Point dataset representing the Centers.
Link field in the input point dataset.
Point, Polyline or Polygon layer representing the destinations.
Link field in the destination dataset.
Optional - connect only closest destination. If not used all destinations that have the same values as a center will be connected to the center.
Optional - Depending on the type of the destination dataset the following options are available
- Point - not used
- Polyline
  - Connect the Center to closest point on the polyline (Default)
  - Connect the Center to the middle point of the polyline
- Polygon
  - Connect the Center to the closest point on the polygon boundary
  - Connect the Center to the centroid of the polygon.
Optional - Cutoff distance - the maximum distance between a Center and a Destination to be used. Destinations that a further than this distance from any Center will not be connected to a Center

Outputs:

New Polyline feature class with single segmented polylines. The attributes of the centers dataset will be preserved

Notes:

The spatial references of both input dataset must have the same geographic coordinate system.
The output spatial reference is the one of the Centers dataset

ET_GPSpiderLink <centers_dataset> <centers_link_field> <Destination_dataset> <destination_link_field> <out_feature class> {closest_only}{connect_center} {Cutoff_distance}

Parameters

Expression	Explanation
<centers_dataset>	A Point feature class or feature layer
<centers_link_field>	A String representing the link field in the centers feature class.
<Destination_dataset>	A Point, Polyline or Polygon feature class or feature layer.
<destination_link_field>	A String representing the link field in the destinations feature class.
<out_feature class>	A String - the full name of the output feature class (A feature class with the same full name should not exist)
{closest_only}	A Boolean - if True, only the closest destination feature to the center will be connected
{connect_center}	A Boolean - the value depends on the type of the destination feature class: Point - not used Polyline False = Connect the Center to closest point on the polyline (Default) True =Connect the Center to the middle point of the polyline Polygon False = Connect the Center to the closest point on the polygon boundary(Default) True = Connect the Center to the centroid of the polygon.
{Cutoff_distance}	A Double representing the Search tolerance (in the units of the {centers_dataset} to be used
