FILI
The path and file name of the input TIFF file.
FILO
The name of the PCIDSK file to which the processed data will be written. This file will be created automatically and must not already exist.
LINKFILE
Instead of creating a new PCIDSK FILO to read the data from FILI, this parameter will create an output file in which the image channel is linked to the original imagery channel. The orbital segment will still be created in FILO. The default value is NO.
CDIC
The channel to read from the CD. The CARTOSAT data product contains only one channel.
A corresponding channel is created in the output PCIDSK (.pix) file.
TEX1
A line of text to describe the file. Typically, the text identifies the location of the data and the reference number of the CD.
If no value is specified for this parameter, the File Header fields in the generated output PCIDSK image database hold the following information:
This parameter is optional.
REPORT
Specifies where to direct the generated report.
Available options are:

CDCARTOSAT reads CARTOSAT TIFF file format data when satellite orthorectification is required. The corresponding metadata file (.txt) should also exist in the same directory. CDCARTOSAT automatically creates a PCIDSK file, reads the requested imagery channel from CD, creates an RPC segment and saves the satellite path information in a segment. Output from CDCARTOSAT is used with OrthoEngine.
CDCARTOSAT extracts from the CD the geographic coordinates of the scene center and the four corner points. The values are stored in the output orbit segment. These points can be used as ground control point (GCP) input for an approximate correction, which is useful when GCPs are unavailable for an area. Note, however, that using geographic coordinates may not produce very accurate results.
If the parameter LINKFILE (Create Linked File) is set to NO, the output file is automatically created with the dimensions required to hold all of the requested data. You should ensure that sufficient disk space is available before running CDCARTOSAT. If LINKFILE is set to YES, the image channel is not created; instead, it is linked to the image channel of FILI, and only one band can be linked.

The user has received a CARTOSAT product in GeoTiff format CD and wants to perform orthorectification on the data. The user wants to extract channel 1 and store the data in the file bandf.pix.
