Classes to interpolate the height of LatLon
locations or
separate lat-/longitudes.
Except for HeightIDW, HeightIDW2 and HeightIDW3, 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.
