Classes HeightCubic, HeightIDWequirectangular, HeightIDWeuclidean, HeightIDWhaversine, HeightIDWkarney, 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.
Except for HeightIDWequirectangular, HeightIDWeuclidean, HeightIDWhaversine and HeightIDWvincentys, the height interpolators in this module require the packages numpy and scipy or geographiclib 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.
