RSMODEL

Description

RSMODEL computes the math model of a satellite image using an ASAR/RADARSAT-specific model, and stores the results in a segment for each input image.

Parameter descriptions

Input: Image layers to be processed

Specifies the input raw image layers to be processed.

InputGCP: Input GCP segment or layer

Specifies the ground control point (GCP) segment or layer to use to compute the model.

InputORB: Input orbit segment or layer

Specifies the orbit segment or layer to use to compute the model.

OutputMM: Math model segment or layer

Specifies the math model segment or layer that stores the computed model.

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

RSMODEL computes the math model of a satellite image using the ASAR/RADARSAT-specific model, and therefore only applies to those two sensors. The mathematical models are stored in a math model segment.

It is an independent model, not a bundle adjustment, but allows accurate solution of the model with few or no GCPs.

The input is a raw image with an orbit segment or layer, and can include GCPs. The output is an updated math model segment or layer for each of the input images.
