VECMERG

Description

VECMERG merges two or more vector segments in a PCIDSK file and writes the result to a new vector segment.

Parameters

Parameter descriptions

Input: Input vector segments or layers

Specifies two or more vector segments or layers to be merged.

Duplicates are not allowed.

Output: Merged vector layer

Specifies the output layer that will receive the newly created vector.

Vector Layer Name

Specifies a name (up to 8 characters) for the merged vector segment or layer.

Vector Layer Description

Describes (in up to 64 characters) the contents or origins of the output data.

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"

Details

VECMERG merges a set of vector segments or layers and saves the merged data set in a new vector segment or layer. The vectors used as input are not changed. The output vector is given the name and description specified by the DBSN (Vector Layer Name) and DBSD (Vector Layer Description) parameters.

All vectors specified by DBVS (Input) must be in the same units (such as PIXEL or UTM).

If the tables are set up differently, VECMERG will merge the tables together. This may result in a very large table.

The Representation Table of the newly created vector segment is copied from the first segment specified.
