Module heights

Height interpolations of LatLon points.

Classes HeightCubic, HeightIDWcosineAndoyerLambert, HeightIDWcosineForsytheAndoyerLambert, HeightIDWcosineLaw, HeightIDWdistanceTo, HeightIDWequirectangular, HeightIDWeuclidean, HeightIDWflatLocal, HeightIDWflatPolar, HeightIDWhaversine, HeightIDWhubeny, HeightIDWkarney, HeightIDWthomas, HeightIDWvincentys, HeightLinear, HeightLSQBiSpline and HeightSmoothBiSpline to interpolate the height of LatLon locations or separate lat-/longitudes from a set of LatLon points with known heights.

Typical usage is one of the following.

First, get or create a set of LatLon points with known heights, called knots. The knots do not need to be ordered in any particular way.

Select one of the Height classes for height interpolation.

>>> from pygeodesy import HeightCubic # or other as HeightXyz

Next, instantiate a height interpolator with the knots.

>>> hinterpolator = HeightXyz(knots, **options)

Then, get the interpolated height of other LatLon location(s) with

>>> h = hinterpolator(ll)

or

>>> h0, h1, h2, ... = hinterpolator(ll0, ll1, ll2, ...)

or

>>> hs = hinterpolator(lls) # list, tuple, generator, ...

For separate lat- and longitudes invoke the .height method

>>> h = hinterpolator.height(lat, lon)

or

>>> h0, h1, h2, ... = hinterpolator.height(lats, lons) # lists, tuples, ...
