Bases: object

Rational Polynomial Coefficients used to map (x, y, z) <-> (row, col) coordinates.

This class contains a mapping between various RPC attributes and values.

err_bias, err_rand

The RMS bias and random error in meters per horizontal axis of all points in image.

Type:: float, optional

lat_off, long_off, height_off

Geodetic latitude, longitude, and height offset.

Type:: float

lat_scale, long_scale, height_scale

Geodetic latitude, longitude, and height scaling.

Type:: float

line_off, samp_off

Line (row) and sample (column) offset.

Type:: float

line_scale, samp_scale

Line (row) and sample (column) offset.

Type:: float

line_num_coeff, line_den_coeff, samp_num_coeff, samp_den_coeff

The twenty coefficients describing a numerator or denominator polynomial corresponding to line (row) or sample (col).
