pyinterp.core.RTree3DFloat32

class pyinterp.core.RTree3DFloat32(self, spheroid: pyinterp.core.geodetic.Spheroid | None = None)

Bases: pybind11_object

Create a spatial index for geodetic scalar values.

This class implements an R*-tree spatial index to efficiently query and interpolate values on the sphere. It supports both geodetic (longitude, latitude, altitude) and Cartesian (ECEF) coordinate systems.

Parameters:

• spheroid – World Geodetic System (WGS) of the coordinate system used to transform geodetic positions (longitude, latitude, altitude) into ECEF coordinates. If not set, WGS-84 is used. Defaults to None.

• ecef – If True, coordinates managed by this instance are in the Cartesian coordinate system (ECEF) and no conversion from geodetic coordinates is performed. Defaults to False.

Raises:

ValueError – If both spheroid and ecef are specified. Either the spheroid or ecef parameter should be set, but not both.
