Module heights

Classes to interpolate the height of LatLon locations or separate lat-/longitudes.

Except for the HeightIDW interpolator, the height interpolators in this module require numpy and scipy to be installed.

Typical usage is as follows. First create an interpolator from a given set of LatLon points with known heights, called knots.

hinterpolator = HeightXyz(knots, **options)

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-/longitudes invoke the .height method

h = hinterpolator.height(lat, lon)

or

h0, h1, h2, ... = hinterpolator.height(lats, lons) # list, ...

The knots do not need to be ordered for any of the height interpolators.

Errors from scipy as raised as SciPyErrors. Warnings issued by scipy can be thrown as SciPyWarning exceptions, provided Python warnings are filtered accordingly, see SciPyWarning.
