Parameter descriptions

FILI

The name of the input PCIDSK (.pix) which contain the displacements or cumulative displacements corresponding to the time intervals bracketed by the temporally ordered acquisition dates.

DBIC

The input channel or channels to be exported.

If not specified, all channels are exported.

Ranges of channels or segments can be specified with negative values. For example, {1,-4,10} is internally expanded to {1,2,3,4,10}. When you are not specifying a range in this way, only 48 numbers can be specified explicitly.

FILREF

This parameter specifies the name of the input file containing the bitmap, vector used to sample the input channels from FILI.

If not specified, all valid pixels in FILI are exported.

DBIC_REF

The bitmap or channel number of the reference file.

ATTNAME

• If ATTNAME is "channame", then use the channel description for the output attribute names.
• If ATTNAME is not empty, then use ATTNAME as the key to look up in the channel metadata for the output attribute names.
• If ATTNAME is empty, then use "Ref_Acquisition_DateTime" and "Dep_Acquisition_Time" channel metadata values for the output attribute names.

FILO

Specifies the name of the GDB vector file that will contain the exported points.

Every PSC is represented as a 2D point with XY coordinates in the projection specified by MAPUNITS. The points have X and Y attributes and value attributes for each raster layer. The name of the value attribute is formed using the start and end acqusition dates of the corresponding layer.

FTYPE

Optionally specifies the output file format type, represented by a three- or four-letter code.

FOPTIONS

The options specific to the format to apply when creating the output file. With each, the default of no options is allowed (empty string).

MAPUNITS

Specifies the projection string for the output points.

If not specified, the projection of FILI will be used.

REPORT

Specifies where to direct the generated report.

Available options are:

• TERM: generates a report on the terminal (default)
• DISK: generates a report on file "IMPRPT.LST"
• OFF: turns off report generation
• <filename>: appends a report to the specified file

Details

RAS2PTATT reads the stack of displacements for each acquisition time step, and exports a vector layer of points.

Example

The following example exports a displacement at the non-overlapping acquisition intervals into the vector layer of point type.

EASI>FILI="PSI_Displacements.pix"    ! output from INSSTACKPSI
EASI>DBIC=
EASI>FILREF=
EASI>DBIC_REF=
EASI>FILO="PSI_Displacements_Vec.pix"
EASI>FTYPE = ""
EASI>FOPTIONS = ""
EASI>MAPUNITS = ""
