Parameter description

-mosaic create mosaics (default: Boolean(True))

Type : Boolean
Remark : optional, default: Boolean(True)
Description:
Possible values:

1	1
0	0
true	true
false	false
yes	yes
no	no
Boolean(True)	Boolean(True)
Boolean(False)	Boolean(False)
True	True
False	False

-mask create grid masks (default: Boolean(True))

-slopeLimits slope limits in degrees (default: [])

Type : Floating-point number
Remark : optional, default: []
Description: optional slope limits (in degrees) for slope classes based analyses. e.g. 20 30 will result in three classes: <20, >=20 to <30, >=30

Common Package/Script Options

Settings concerning the general options for (package) scripts.

-infile input text file, directory or strip file

Type : String
Remark : mandatory
Description: As input either the name of an ASCII file (extension .txt) containing the names of the data files (one file per line) or an expression using wildcards to specify the respective data sets are accepted.

-outfile output directory or settings file (.txt)

Type : String
Remark : optional
Description: Specifies the directory where the final results are stored. If not specified, the results are created in the current working directory.

-temp temporary directory (default: current directory)

Type : String
Remark : optional, default: '.'
Description: Specifies the directory where all intermediate results are stored. If not specified, a TEMP subdirectory is created in the current working directory. Additional subdirectories (one per involved module) are created.

-cfg configuration file

Type : String
Remark : optional
Description: The name of a configuration file containing all relevant calculation parameters is expected. If not specified, the default cfg files as provided by the OPALS distribution are used.

-projectDir project directory

Type : String
Remark : optional
Description: The default project directory is the current working directory, but can be easily changed by this parameter. All path parameters, if not specified as absolute paths, are interpreted relative to the project directory.

-skipIfExists skip processing if result already exists (default: Boolean(True))

Type : Boolean
Remark : optional, default: Boolean(True)
Description: Skip processing if result already exists. In order to re-run current script it is useful to repeat the processing only if the respective output does not already exist. This allows for incremental processing of large projects.
Possible values:

1	1
0	0
true	true
false	false
yes	yes
no	no
Boolean(True)	Boolean(True)
Boolean(False)	Boolean(False)
True	True
False	False

-gearman address and port of gearman job server

Type :
Remark : optional
Description: currently this option is not yet supported. placed here for future reference

Logging Options

Settings concerning the verbosity level of logging.

-screenLogLevel verbosity level of screen output (default: info)

Type : fromStr
Remark : optional, default: info
Description: The minimum level of log message importance to print on the screen

-fileLogLevel verbosity level of log file output (default: info)

Type : fromStr
Remark : optional, default: info
Description: The minimum level of log message importance to export to the xml-log
