Finds the gaps in a given Cube.

Overview Parameters Example 1

Description

This program will find any gaps in a Cube and display their beggining and final lines as well as their band. These values will be placed into the file defined by the TO parameter.

Example 1

Finds Image Gaps

Description

This example shows how findgaps works on the cube I11971007RDR_lev1.cub.

Command Line

findgaps FROM=I11971007RDR_lev1.cub TO=results.txt
Searches I11971007RDR_lev1.cub for gaps based on the default Correlation Tolerance of CORTOL=0.7

Input Image

I11971007RDR_lev1.cub

The image

Parameter Name: FROM

This is the image I11971007RDR_lev1.cub within which line gaps are being found.

Data File

Links open in a new window.
results.txt

In the case of no gaps, the TO output file parameter will be empty.

When there are gaps in the cube image, then there is a pvl display in the TO file. In this example, that file is results.txt as shown here. This group displays the band these gaps were found in, the starting line for the particular gap, the correlation coefficient that initiated the finding of that gap, as well as the last line of the given gap.
