General Tools - Data Transformation - Transform Raster Data

Previous pageReturn to chapter overviewNext page

Purpose

 

The following raster transformation can be performed:

 

Data type (e.g. 16 bit to 8 bit).

Data unit (e.g. Intensity to Amplitude). This functionality does not change the pixel value, but just the annotation in the product header file (.sml).

Value assigned to dummy pixels.

Density slicing.

Bytes and/or pixel swapping.

Data normalisation.  

 

Technical Note

 

None.

 

Input File

 

Input file

Input file name of the data to be processed. This file is mandatory.

 

Parameters - Principal Parameters

 

Data Type

A new data type can be specified.

 

Data Units

A new data unit can be specified.

 

New Dummy Value

By setting this flag, a new value is assigned to dummy pixels in the input data. The new dummy value replaces the old one in the output file header.

 

NaN

By setting this flag, the new value assigned to dummy pixels is "Not a Number".

 

Value

The entered value will be assigned to dummy pixels.

 

Value to set to Dummy

By setting this flag, pixels with the specified value will be transformed to dummy.

 

Value

Value of the pixels to be transformed to dummy.

 

Set Dummy to Value

By setting this flag, the value of dummy pixels is transformed to a new one. The original dummy value is not changed in the output file header.

 

Value

The entered value will be assigned to dummy pixels.

 

Byte Order MSBF

By setting this flag to true the output byte order is Motorola (or Big Endian) binary type. If set to false (default), the byte order is LSBF or Intel/Little Endian binary type.

 

Normalize

By setting this flag, the following formula is adopted to define the new scaling factor for the output image:

 

Value/input mean + (std multi * std input)

 

Norm Value

The mean value for the output transformed image (see formula above).

 

Norm Standard Multi

The standard deviation multiplier (see formula above).

 

Set Norm Scale

By setting this flag, a parameter allowing to back transform the data from the normalization is stored.

 

Swap Rows with Columns

By setting this flag the input image is rotated of 90° clockwise and mirrored with respect to the vertical axis.

 

Swap Rows

By setting this flag the input file is mirrored with respect to the horizontal axis.

 

Swap Columns

By setting this flag the input file is mirrored with respect to the vertical axis.

 

Maximum Slicing Limits

Maximum pixel value for the slicing. Only pixels whose value ranges from the Min to the Max thresholds are extracted.

 

Minimum Slicing Limit

Minimum pixel value for the slicing. Only pixels whose value ranges from the Min to the Max thresholds are extracted.

 

Set Outsiders to Limits

By setting this flag, the values lower than Min or higher than Max are set respectively to the Min and Max value. If this flag is unchecked the input values outside the Min - Max range are set to dummy.

 

Parameters - Global

 

It brings to the general section of the Preferences parameters. Any modified value will be used and stored for further processing sessions.

 

Parameters - Other Parameters

 

It brings to the general section of the Preferences parameters. Any modified value will be used and stored for further processing sessions.

 

Output Files

 

Output file

Output file name of the transformed data. This file is mandatory.

 

_rsp        

Transformed data and associated header files (.sml, .hdr).

 

Details specific to the Units of Measure and Nomenclature of the output products can be found in the Data Format section.

 

General Functions

Store Batch        

The processing step is stored in the batch list. The Batch Browser button allows to load the batch processing list.

 

Close        

The window will be closed.
