xdem.coreg.Tilt

class xdem.coreg.Tilt(subsample=500000.0)

DEM tilting.

Estimates an 2-D plan correction between the difference of two DEMs.

__init__(subsample=500000.0)

Instantiate a tilt correction object.

Parameters

subsample (int | float) – Factor for subsampling the input raster for speed-up. If <= 1, will be considered a fraction of valid pixels to extract. If > 1 will be considered the number of pixels to extract.

Methods

__init__([subsample])	Instantiate a tilt correction object.
apply(dem[, transform, crs, resample])	Apply the estimated transform to a DEM.
apply_pts(coords)	Apply the estimated transform to a set of 3D points.
centroid()	Get the centroid of the coregistration, if defined.
copy()	Return an identical copy of the class.
error(reference_dem, dem_to_be_aligned[, ...])	Calculate the error of a coregistration approach.
fit(reference_dem, dem_to_be_aligned[, ...])	Estimate the coregistration transform on the given DEMs.
fit_pts(reference_dem, dem_to_be_aligned[, ...])	Estimate the coregistration transform between a DEM and a reference point elevation data.
from_matrix(matrix)	Instantiate a generic Coreg class from a transformation matrix.
from_translation([x_off, y_off, z_off])	Instantiate a generic Coreg class from a X/Y/Z translation.
residuals(reference_dem, dem_to_be_aligned)	Calculate the residual offsets (the difference) between two DEMs after applying the transformation.
to_matrix()	Convert the transform to a 4x4 transformation matrix.

Attributes

is_affine

Check if the transform be explained by a 3D affine transform.
