Two parcel viewers, perspective and aerial, show a basic, interactive view of downtown San Francisco and SOMA:
We think the perspective view is cooler.
These viewers are based on renderings of SOM's digital city model of San Francisco, provided by Mark Schwettmann, that combine realistic shading and identifying parcel information encoded as a color. Navigating around them with your mouse reveals block numbers and lot numbers (where available), while clicking takes you to the associated Assessor's parcel record or block map. In some places, the Assessor's information is incomplete. In others, SOM's city model metadata is incorrect.
Actionscript source code is available.
