vertices2corners_ecef

vertices2corners_ecef(vertices)

Converts trixel vertices datastructure (c.f. to_vertices()) to trixel corners in ECEF representation.

Parameters:

vertices: tuple

vertices data structure

Returns:

corners: numpy.array

First dimension are the sids (same as input first dimension). Second dimension the corners (1,2,3). Third dimension x,y,z.

Examples

>>> import starepandas
>>> sids = numpy.array([3458764513820540928])
>>> vertices = starepandas.tools.trixel_conversions.to_vertices(sids)
>>> starepandas.vertices2corners_ecef(vertices)
