Determines if another percentage polygon overlap has occurred, returning the polygon and the percentage overlap with the input polygon.

Syntax

05 GDL-FIND-NEXT-POLYGON-OVR-PCT.
      10 GDL-FNPOP-HANDLE PIC S9(09) BINARY.
      10 GDL-FNPOP-OUTPUT-SHAPE PIC S9(09) BINARY.
      10 GDL-FNPOP-OVERLAP COMP-2.
      *
      CALL "GDLFNPOP"
      USING GDL-FIND-NEXT-POLYGON-OVR-PCT GDL-RETURN-CODE.

Arguments

GDL-FNPOP-HANDLE

The gdlFileHandle returned by GDLSOF (GDL-OSF- STATIAL-HANDLE). Input.

GDL-FNPOP-OUTPUT-SHAPE

A pointer to the overlapping polygon. Output.

GDL-FNPOP-OVERLAP

The percentage of overlap. Output.

Return Values

GDL-OK Success
GDL-ERROR An internal error occurred
GDL-NOT-FOUND No further returns are available

Prerequisites

GDLFPOP

Alternates

GDLFNPO - For better performance when percent overlap is not needed.

Notes

The percentage overlap determines the confidence rating.

Following instances of this procedure, you should call GDLSF with the output polygon when you are finished using the output polygon to release system resources.
