  We have derived a new photographic photometry and proper motions for 20000
stars with completeness to V = 18 in the direction of galactic center at the
intermediate latitude (l = 3 deg,b = 47 deg; alpha(1950)=15h 18m, delta(1950) =
+02deg 16') for a 15.5 sq deg field. The combination of four glass copies of
the Palomar Observatory Sky Survey (i.e. POSS 1402 E&O and POSS 1429 E&O) has
been used as a first epoch for proper motion determination. The random error of
the proper motions is approximately 0.''3/cen to V=17. The photometric accuracy
ranges between 0.07 to 0.10 in the V, B and U bands. We stress the importance
of the magnitude and color effects in astrometric surveys of field stars. Using
color-magnitude diagrams of a few cluster member stars, a new distance of
6.9+-0.5 kpc is derived for M5 and 20.3+-0.8 kpc for Pal 5 globular clusters.
This is in good agreement with other determinations. We have analyzed the
components of U+W and V galactic space motions resulting from the accurate
proper motions survey. No dependence with z distance is found in the asymmetric
drift of the thick disk population. New estimates of the parameters of the
velocity ellipsoid have been derived for the thin disk, thick disk and halo
populations of the Galaxy.
