VECZREF

Description

Calculates and applies geoid undulation to convert the vector z-values between ellipsoid heights and mean sea level elevation using a global model.

Parameters

Name	Type	Length	Value range
Input: Input vector segment *	Vector port	1 - 1
Output: Output vector segment	Vector port	0 - 1
Input Elevation Reference	String	0 - 1	MSL | ELLIPS
Elevation Unit	String	0 - 1	METER | FEET
Report	String	0 - 192	See parameter description

* Required parameter

Parameter descriptions

Input: Input vector segment

Specifies the input vector segment to process.

Output: Output vector segment

Specifies the output vector segment to receive the converted data.

If the input and ouptut files (FILV and FILO) are the same, and the output vector segment (DBOV) is identical to the input vector segment (DBIV), the specified segment is overwritten with the new output. If DBOV exists, it is overwritten with the converted segment. If DBOV is not specified or is specified but does not already exist, a new output segment is created.

Input Elevation Reference

Specifies the original (input source) vertical reference for elevation values in the vector layer.

Elevation Unit

Specifies the units of the elevation values.

If the ELEVATION_UNITS metadata tag for the input file exists, this is used by default; otherwise, the default unit is METER.

Report

Specifies where to direct the generated report.

Available options are:

• LOG: generates a report on the terminal (default)
• <modulename.RPT>: appends a report to the module's RPT file
• DISK: generates a report on file "IMPRPT.LST"
