Purpose
This panel enables to modify some general processing parameters.
Parameters - General parameters
OpenCL Platform Name
The list of OpenCL platforms available for parallel computing. Select which platform to use for OpenCL computing with SARscape. Please refer to the SARscape_OpenCL_Installation.pdf document for more details.
OpenCL Device Name
The list of OpenCL devices supported by the selected OpenCL platform. Select which device to use for OpenCL computing with SARscape. Please refer to the SARscape_OpenCL_Installation.pdf document for more details.
Maximum available memory size in (GB)
This parameter tells how much memory a SARscape processing is allowed to use. This value is more a hint to SARscape and not 100% accurate. If a CPU-only OpenCL runtime is selected, the amount of system memory consumed by the runtime is not affected by this parameter.
Maximum iterations for PFA geocoding
This parameter controls the maximum number of iterations in the geocoding procedure of each image point.
Trace Level
The parameter controls the extent of the information written into the SARscape trace file. A low number allows more information to be written, a higher the opposite.
Byte Order for Import
By setting the relevant flag the data are imported or transformed using the specified byte order.
MSBF
The output byte order is Motorola (or Big Endian) binary type.
LSBF
The output byte order is Intel (or Little Endian) binary type.
By setting this flag the temporary files are removed at the process completion.
Generate Quick Look
By setting this flag the output file is generated also in Tiff or PNG format. These files are intended essentially for visualisation purposes. The extension "_ql" is automatically added to the output file name. PNG allows .kml files with transparent dummy values.
Shape Max Nr of Points
If values other than -1 are entered, the output shape file is split in several parts (each marked by a progressive numbering - _01; _02; etc.); each part of the shape contains a portion of the total number of points, which corresponds to the value entered.
Enable Completed Panel
By setting this flag to True (default selection) the Completed panel is displayed once the process is completed.
Insert geo points info in ENVI header
By setting this flag to True (default selection) geo points ENVI parameters are included in the header file. Please, consider that if the image that include this information in the header file is used as input file in the Generate Ground Control Points tool, the image will be considered as a geocoded image and not as a slant range image. For this reason, coordinates are considered as Lat/Lon insead of image coordinates.
Generate Batch save during Workflow execution
By setting this flag to True (default selection) a batch file that describes all the steps in the workflow is updated. The file name is "Batch file name"+"_wf".
Saturation Default
The default saturation value for the TIFF format.
Quick Look Format
Select the format of the Quick Look (TIFF or PNG). The Generate Quick Look flag must be set to TRUE.
Date String prefix in dbf file
The prefix 'D' or 'D_' can be specified for the date in the dbf file.
Interpolation Type
By setting the relevant flag, the interpolation type is specified.
Nearest Neighbour
Bilinear Interpolation
3rd Order Cubic Convolution
4th Order Cubic Convolution
Interpolation Buffer Size
The software keeps in memory a portion of image (rows x columns), to improve the processing performance.
If this portion is very large, the process will be fast but a large part of the RAM will be used by the tool; if otherwise the portion is small, the process might fail since a larger part of the image is required to successfully execute the process.
Fill Dummy
By setting this flag the software will assign a value to the dummy (i.e. NaN) pixels according to the chosen ''Fill Dummy Method''. This correction will only be applied to internal pixels leaving image border as is.
Fill Dummy Method
Two methods can be used to assign a value to dummy pixels :
–Min image value: The minimum backscatter value will be assigned to the NaN value pixels.
–Mean near pixels: The mean backscatter value of the neighboring pixels will be assigned the NaN value pixels.
Dummy Removal
By setting this flag the output geocoded files, generated in the Geocoding and Radiometric Calibration, Phase to Displacement Conversion (Interferometry and ScanSAR Interferometry modules) and Phase to Height Conversion (Interferometry and ScanSAR Interferometry modules), will be automatically resized in order to remove the dummy area exceeding the frame border.
Load Images
By setting this flag the output file (or files in case of a list) is automatically loaded in ENVI. In case of a large lists of files and/or in case of large acquisitions, it is convenient to disable this flag in order to avoid the loading of a large amount of data in ENVI(e.g. after the import of several acquisitions). Note: this flag has no influence on process run from the batch browser (where no data is automatically loaded at any time).
Shape x field
Field of the input shape file corresponding to the x coordinate.
Shape y field
Field of the input shape file corresponding to the y coordinate.
Shape z field name
Field of the input shape file corresponding to the z coordinate.
Shape field name
Field of the input shape file that will be used to compute the skew estimation.
General Functions
