  We present new three-dimensional (3D) interstellar extinction maps in the $V$
and Gaia $G$ filters within 2 kpc of the Sun, a 3D differential extinction
(dust spatial distribution density) map along the lines of sight in the same
space, a 3D map of variations in the ratio of the extinctions in the $V$ and
Gaia $G$ filters within 800 pc of the Sun, and a 2D map of total Galactic
extinction through the entire dust half-layer from the Sun to extragalactic
space for Galactic latitudes $|b|>13^{\circ}$. The 3D maps have a transverse
resolution from 3.6 to 11.6 pc and a radial resolution of 50 pc. The 2D map has
an angular resolution of 6.1 arcmin. We have produced these maps based on the
Gaia DR3 parallaxes and Gaia, Pan-STARRS1, SkyMapper, 2MASS, and WISE
photometry for nearly 100 million stars. We have paid special attention to the
space within 200 pc of the Sun and high Galactic latitudes as regions where the
extinction estimates have had a large relative uncertainty so far. Our maps
estimate the extinction within the Galactic dust layer from the Sun to an
extended object or through the entire dust half-layer from the Sun to
extragalactic space with a precision $\sigma(A_\mathrm{V})=0.06$ mag. This
gives a high relative precision of extinction estimates even at high Galactic
latitudes, where, according to our estimates, the median total Galactic
extinction through the entire dust half-layer from the Sun to extragalactic
objects is $A_\mathrm{V}=0.12\pm0.06$ mag. We have shown that the presented
maps are among the best ones in data amount, space size, resolution, precision,
and other properties.
