Bilinear interpolation is used so that values will vary smoothly within a
longitude-latitude grid cell. Note that the sign convention for
longitude and latitude must match that in topo.
topoInterpolate(longitude, latitude, topo)Vector of longitudes (in the same sign convention as used in
topo).
Vector of latitudes (in the same sign convention as used in
topo).
A topo object, i.e. inheriting from
topo-class.
Vector of heights giving the elevation of the earth above means sea level at the indicated location on the earth.
