You can specify the distance, in feet, to use as a buffer around polygons defined in the standard boundary files or a user-defined boundary file. This is an optional comparison between a point and the buffered zone. The returned data will indicate whether the point is inside the polygon, inside the polygon but in the buffered zone, or outside the polygon but still inside the buffered zone (as shown in the following illustration):
To define the buffer distance for the boundary files (SPD, IPD, PTC & PAY), use the following:
Batch processing |
Use the Input buffer distance field in the BUFOUT parameter card. |
Integrator Series API |
Use the szBoundaryBuffDist element in the |
Callable Functions |
Use the MCA-BOUNDARY-BUFFER-DIST field in the Matcher Control Area prior to Calling the GTMATCH program. |
To define the buffer distance with a user-defined boundary file, use the following:
Batch processing |
Use the Input buffer distance field in the BF2OUT parameter card. |
Integrator Series API |
Use the szUserBoundBuffDist element in the |
Callable Functions |
Use the MCA-USER-BND-BUFFER-DIST field in the Matcher Control Area prior to Calling the GTMATCH program. |
The results for the point comparison to a buffered area on a boundary is covered in Distance & status returns for a point comparison to a boundary.
