STITCH

Description

Some satellite imagery can be provided in different tiles with orbital data information for each tile. STITCH lets you merge individual tiles that are obtained from the same orbit on the same day, into one complete scene. If the input files are PIX files with ORBIT segments, this program will rebuild a new orbital data for the whole strip to maintain the ephemeris information. If the input files are TIF/NITF files with RPC, this program will rebuild a new RPC for the whole strip. Having a single scene simplifies math modeling, orthorectification, mosaicking, and other image post-processing.

Parameter descriptions

Input: Input image layers

Specifies the input image layers to be processed.

InputORB: Input orbit layer

Specifies the input orbit layer that contains ephemeris information.

InputGCP: Input GCP layer

Specifies the input ground control point (GCP) layer.

Output: Output file name

Specifies the output PCIDSK file that will contain the stitched images. If the specified file already exists, it will be overwritten.

OutputOrbit: Output satellite orbital ephemeris layer

Specifies the output satellite orbital ephemeris layer.

OutputGCP: Output GCP layer

Specifies the output layer that will contain the GCPs.

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

STITCH lets you stitch ASTER, IKONOS, QuickBird, Worldview and SPOT image tiles acquired on the same day in a single pass of a satellite. This program supports PIX files with ORBIT segments or TIF/NITF files with RPC. A new orbit segment or RPC segment for the whole strip will be created.
