Extracts portions of an existing Control Network

Overview Parameters Example 1

Description

Extracts Control Points into a new Control Network from a specified Control Network in accordance to specified filters.

Currently, the filters are divided into four categories: Exclusive Filters, Inclusive Filters, Cube Filters, and Lat/Lon Filters.

Exclusive Filters prevent extraction. They are taken into consideration last and have the highest priority. This means that if any other filter creates a selected Exclusive Filter condition during processing, that Exclusive Filter will prevent the extraction. For example, if the Cube Filters CUBES, CUBELIST, and CUBEMEASURES are used along with the Exclusive Filter NOSINGLEMEASURES, then an input Control Point which contains only one cube in the CUBELIST will not be extracted, regardless of the number of Control Measures it had on input. This is because NOSINGLEMEASURES will see it as a Control Point with exactly one Control Measure and prevent its extraction. If only Exclusive Filters are used, all Control Points/Measures that do not have an exclusive property will be extracted.

Inclusive Filters allow extraction. They only extract Control Points and/or Measures that are included in the Inclusive Filter. In addition, each Inclusive Filter is associated with an explicit property of the Control Point/Measure. If more than one Inclusive Filter is selected, only Control Points/Measures that contain all inclusive properties will be extracted.

Cube Filters also allow extraction, however, they pertain to the cubes contained within the Control Points/Measures. Option RETAIN_REFERENCE will extract the Reference even if not in the Cube List.

Lat/Lon Filters allow extraction as well, however, they only extract Control Points/Measures that lie in the lat/lon bounding box.

A summary of the Control Points not extracted, listed by the filter which prevented them from being extracted, can be included in optional report files. See the PREFIX and filter keywords for more details. The following table lists the output file names, the corresponding filter for the output file, and a description of the contents of the output file. These output files will only be generated if PREFIX has been defined.

OutputReport Filter Reason for not extracting the points/measures in this report
[PREFIX]IgnoredPoints.txt NOIGNORE These points are set to ignored.
[PREFIX]IgnoredMeasures.txt NOIGNORE These measures are set to ignored. Ignored reference measures are always extracted, however they are still listed in this report with the note: Ignored measure but extracted since it is Reference.
[PREFIX]SingleMeasurePoints.txt NOSINGLEMEASURES These points have only one measure.
[PREFIX]MeasurelessPoints.txt NOMEASURELESS and REFERENCE These points have no measures.
[PREFIX]NonReferenceMeasures.txt REFERENCE These measures are not reference measures.
[PREFIX]NonFixedPoints.txt FIXED These points are not fixed.
[PREFIX]NonConstrainedPoints.txt CONSTRAINED These points are not constrained.
[PREFIX]NonEditLockedPoints.txt EDITLOCKED These points are not editlocked.
[PREFIX]TolerancePoints.txt TOLERANCE These points have line and/or sample less than the given PIXELTOLERANCE.
[PREFIX]NonListedPoints.txt POINTSLIST These points are not in the given POINTLIST.
[PREFIX]NonCubePoints.txt CUBES These points have no measures corresponding to the given CUBELIST.
[PREFIX]NonCubeMeasures.txt CUBES, CUBEMEASURES, and RETAIN_REFERENCE These are measures for extracted points that do not correspond to cubes in the given CUBELIST. If RETAIN_REFERENCE is true, all reference measures for extracted points will be extracted, however any reference measure that does not correspond to cubes in the cubelist will still be listed in this report with the note: Reference not in the cubelist but extracted since RETAIN_REFERENCE=true.
[PREFIX]LatLonOutOfRange.txt LATLON These points have a latitude and/or longitude that is not in the given MINLAT/MAXLAT or MINLON/MAXLON range.
[PREFIX]NoLatLonPoints.txt LATLON These points do not have a determineable latitude and/or longitude value.

Lat/Lon Filters: LATLON

Description

When selected, all Control Points that are inside of the provided latitude and longitude ranges will be extracted. Control Points whose latitude and/or longitude cannot be computed will not be extracted.

Fixed Points will use the lat/lon values provided in the input control network, while Free Points will calculate the lat/lon from the images provided by the FROMLIST. These calculated lat/lon values will be added to Free Points in the output control network for reference purposes. However, no Isis application will use these lat/lons that are added to Free Points.

When option PREFIX is used, report files [PREFIX]LatLonOutOfRange.txt and [PREFIX]NoLatLonPoint.txt will also be created. Each Control Point they list was not extracted due to this filter.

Control Points in [PREFIX]LatLonOutOfRange.txt did not fall within the provided lat/lon bound. Each Control Points listed in [PREFIX]NoLatLonPoint.txt do not have a determinable Latitude or Longitude.
