Creation of digital catalog of real coordinates

Extension of a file - *.fct, a name of a file is association of a name of the source raster and a text constant ".rsw". For transformation by elements of external orientation the digital catalog of real coordinates of control points has the following structure:

.FCT

.RST

// the comment

-1 Xi1 Yi1

-2 Xi2 Yi2

-3 Xi3 Yi3

-4 Xi4 Yi4

N1 X1 Y1

N2 X2 Y2

..............

Nm Xm Ym

.END

where. FCT - a file label (an obligatory field),

.RST - an attribute, that coordinates of control points are specified in elements of a raster (not obligatory  field, but if this label is not present, it is considered that coordinates are specified in the preset system of coordinates in meters),        

// - the beginning of a comment line (allowable not obligatory field),

N1 - Nm - numbers of control points of a raster (an obligatory field - only numerical values),

X1 - Xm - real coordinates of control points in elements of a raster

Y1 - Ym (if there is a label .RST) or in meters in the preset system

                        of coordinates (obligatory field),

The first two or four lines contain conditional numbers and real coordinates of labels of a photo.

.END - the end of a file (an obligatory field).
