Closest Neighbor

The Analysis | Evaluate | Closest Neighbor command allows you to identify a point object and search for the closest neighboring point. This command is typically used on pin maps and other MapViewer maps created from point objects. In order for the Closest Neighbor command to be active, at least one point object must be present on the current map layer. Point objects must have an associated primary ID in order to be involved in the closest neighbor function.

Find Closest Neighbor Dialog

All the options required to locate the closest neighbor of a point object are located in the Find Closest Neighbor dialog.

Find the closest neighbor, select starting point, choose whether to include all layers, and view

point information in the Find Closest Neighbor dialog.

The Closest neighbor (point) from list contains all the points from which you can find the closest neighbor. The points are listed by primary IDs.
To search for the closest neighbor across all the map layers, check the Include all layers box. If this option is disabled, the closest neighbor search is based on the active layer only.
Once you have chosen a point from the Closest neighbor (point) from list, click the Find button to identify the closest neighbor. The closest neighbor is identified and the distance between the two points is reported to the right of the Find button. For known projections, the distance units are specified with the Surface distance units setting on the Units page in the Property Manager.
The spreadsheet section of the Find Closest Neighbor dialog contains all of the available information about the point. The Data Column lists the type of data available for the identified closest neighbor. The corresponding values for the Data Column are listed in the Data Value column. The layer the point is located on is identified in the Layer column. If you wish to know the precise location of the closest neighbor, the point's centroid location is listed in the Centroid (X) and Centroid (Y) columns. The units of the centroid location are specified with the Coordinate display units setting on the Units page in the Property Manager. To create a report of the closest neighbor data, click the Create Report button.
