INP=A Input IBIS tabular file containing the
input points. Also contains columns to
receive the result of mapping.
COLS=(C1,C2) Columns in the IBIS tabular file that
contain or will contain the mapping
coordinates (depending on the direction
of the mapping). The order of C1 and C2
is the same as the order of coordinates
in the GeoTIFF label (for example, in
ModelTiePointTag=(0,0,0,121.0,55.0,0.0)
the order is lon then lat. Generally,
the order should be East then North.
COLS=(C1,C2) Columns in the IBIS tabular file that
contain or will contain the pixel
coordinates always in the order (line,
sample).
'MAPTOPIX Keyword to convert map to pixel. One, but
not both of the mapping direction keywords
must be given. The pixel column will be
erased and filled with the results of
conversion.
'PIXTOMAP Keyword to convert pixel to map. One, but
not both of the mapping direction keywords
must be given. The map column will be
erased and filled with the results of
conversion.
Coordinate values to ignore. An input (whether map or pixel) will be ignored if they test equal to this value within 1.0e-14. The output value will be set to the input value. This is a pair of values, so both values have to match to be ignored.
