  Spicules are intermittently rising above the surface of the Sun eruptions;
EUV jets are now also reported in immediately above layers. The variation of
spicule orientation with respect to the solar latitude, presumably reflecting
the confinement and the focusing of ejecta by the surrounding global coronal
magnetic field, is an important parameter to understand their dynamical
properties. A wealth of high resolution images of limb spicules are made
available in H CaII emission from the SOT Hinode mission. Furthermore, the
Hough transform is applied to the resulting images for making a statistical
analysis of spicule orientations in different regions around the solar limb,
from the pole to the equator. Spicules are visible in a radial direction in the
polar regions with a tilt angle (less than 200). The tilt angle is even reduced
to 10 degrees inside the coronal hole with open magnetic field lines and at the
lower latitude the tilt angle reaches values in excess of 50 degree.
