Parameter descriptions

MOEPROJ

Lists the OrthoEngine project files to merge into a single project file. File names may be separated by commas, or defined using a wildcard, such as e:\data\ortho*.prj

TFILE

Specifies the name of the input text file containing the list of OrthoEngine project files to merge.

For example:

TFILE = "file.txt" 

where file.txt contains:

"c:\data\west_rhill.prj"
"c:\data\east_rhill.prj"
"c:\data\north_rhill.prj"
"c:\data\south_rhill.prj"

If no path is specified in the text file, the working directory is used.

Either MOEPROJ or TFILE must be specified, but not both. If MOEPROJ is specified, TFILE is ignored.

MERGPRJ

Specifies the name of the output merged OrthoEngine project file. If the file already exists, it is overwritten.

PREPEND

Specifies the type of automatic prefix to be added to the point IDs.

To prevent duplicating point IDs, the GCPs and TPs of the project files to be merged are prefixed with a sequential number. For example, if three OrthoEngine project files are to be merged, the GCPs and TPs are prefixed with "1_ " for the first file, "2_ " for the second, and "3_ " for the third. If the GCP IDs are already unique and stereo GCPs are to be included, only the IDs of the TPs are prefixed.

REPORT

Specifies where to direct the generated report.

Available options are:

• TERM: generates a report on the terminal (default)
• DISK: generates a report on file "IMPRPT.LST"
• OFF: turns off report generation
• <filename>: appends a report to the specified file

Details

MERGPROJ merges existing OrthoEngine project files that have identical math model types, including projection and datum. For airphoto projects, the camera calibration data must be identical. Incompatible files are excluded from the merge.

Either MOEPROJ or TFILE must be specified for the program to run successfully, but not both. If MOEPROJ is specified, TFILE is ignored.

Example

This example merges the two OrthoEngine project files named 'airphoto_1.prj' and 'airphoto_2.prj' into a single project file named 'MergedProj.prj'.

EASI>MOEPROJ	=	"airphoto_1.prj,airphoto_2.prj"	! input project files
EASI>TFILE	=		! uses MOEPROJ to specify input files
EASI>MERGPROJ	=	"MergedProj.prj"	! output OrthoEngine project file
EASI>PREPEND	=		! Defaults to BOTH (adds prefix to TP and GCP IDs)
EASI>REPORT	=	"TERM"	! Uses the terminal as the default for printouts

EASI>R MERGPROJ
