Only in very rough terms. We know it is a spiral type galaxy, possibly of class SBc or Sc, and we know very roughly where the major spiral arms are located, but as for details equivalent to photographic accuracy, we do not know. All we know are where some of the major star forming regions, nebulae, star clusters and large gas clouds are located. There are several competing'models' of what the Milky Way looks like from outside.

The above image shows the Milky Way from our location and was taken by the COBE satellite at 3.5 microns in the infrared spectrum. Clearly we live in a flattened galaxy similar in basic form to spiral galaxies we can study elsewhere in the universe.
