ORBITWR

Description

Writes information from a specified orbit segment to a text file.

Parameters

orbitwr(file, orbit, tfile, rtyp)

Name	Type	Caption	Length	Value range
FILE *	str	Input file name	1 -

RTYP	str	Information report type	0 - 5	BRIEF \| SHORT \| FULL Default: SHORT

* Required parameter

Parameter descriptions

FILE

Specifies the name of the PCIDSK image file that contains the orbit segment to be written to a text file.

ORBIT

Specifies the input orbit segment to write to a text file. If this parameter is not specified, ORBITWR writes the first orbit segment to the text file. If specified, this value must be greater than zero.

TFILE

Specifies the name of the output text file that will contain the orbit segment information.

The text file must not exist before running ORBITWR. If the text file exists, ORBITWR exits without processing.

RTYP

Specifies the type of information that is written to the output text file.

Three forms may be specified:

Brief: writes part of the header information to the text file
Short: writes all of the header information to the text file. This is the default value.
Full: writes all the header and data lines information to the text file

Details

ORBITWR writes orbit information from a specified orbit segment (ORBIT/InputOrbit) from a PCIDSK file (FILE) to a defined output orbit data text file (TFILE).

Example

Write the full orbit information from the first segment in the file 'spotleft.pix' to a new file named 'spot.orb'.

from pci.orbitwr import orbitwr

file='spotleft.pix'
orbit=[]                  # defaults to 1st orbit segment
tfile='spot.orb'
rtyp='FULL'

orbitwr(file, orbit, tfile, rtyp)

The output text file 'spot.orb' contains the following information:

SatelliteDesc       :                                 
SceneID             : S1H1890831185708                
SatelliteSensor     : PLA-1
SensorNumber        : 1 
DateImageTaken      : 31/08/1989            
SupSegExist         : TRUE
FieldOfView         : 1.20000000000000E-005
ViewAngle           : 3.32258329702161E-001
