Initialization Procedures

GDLINIT

Initializes the GDL Library. You must call this procedure before any other library procedure.

GDLTERM

Releases resources allocated from GDLINIT.

File Operation Procedures

GDLOSF

Opens a file for spatial analysis.

GDLCSF

Closes the file previously opened by GDLOSF.

GDLGTVER

Returns a string containing the GDL library version number.

GDL/zOS-Specific Procedures

GDLCST

Returns the confidence surface type based on information from a GeoStan™ match.

GDLGES

Generates an error surface (geo-variance region) from a match found inside the GeoStan/zOS handle.

GDLGSL

Determines the street segment length or the length of a diagonal.

GDLSS

Sets properties of the gdlHandle.

Comparison Operation Procedures

GDLFN

Finds the nearest point or line to a given point.

GDLFNX

Finds the next nearest feature after a successful call to GDLFN.

GDLFPO

Determines if a binary polygon overlap has occurred and, if so, returns the polygon that is in overlap with the input polygon.

GDLFNPO

Determines if another binary polygon overlap has occurred and, if so, returns the polygon that is in overlap with the input polygon.

GDLFPOP

Determines if a percentage polygon overlap has occurred and, if so, returns the polygon and the percentage overlap with the input polygon.

GDLFNPOP

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

GDLPIP

Finds the first polygon that contains the input point and determines within which polygon a geocoded address is located.

GDLPIPN

Finds the next polygon that contains the input point.

GDLND

Determines the minimum distance that exists between an error surface or a geocoded point and another point or line.

GDLFD

Determines the distance between the farthest point of the error surface and the nearest point of the feature (point, line or polygon).

GDLMD

Determines the Manhattan distance between two points.

GDLDIST

Determines the straight line distance between two points.

Shape Operation Procedures

GDLSGL

Returns properties from the shape object in the form of a long integer.

GDLSGS

Returns properties from the shape object in the form of a string.

GDLSC

Creates a shape of a given type with specified coordinates.

GDLSGC

Returns the coordinates with which a shape of a given type is created.

GDLSF

Deallocates any memory associated with a shape.
