Here is the unofficial Google Map for AALL 2009.  Just like with the wiki, you can add landmarks of great restaurants, hotels, or other points of interest in the Washington, DC area. (Click "view larger map" link at bottom if you'd like to be taken to full map.)

Google Maps uses a close variant of the Mercator projection, so it cannot show areas around the poles. A related product is Google Earth, a stand-alone program which offers more globe-viewing features, including showing polar areas. Google Maps Navigation is free. A potential drawback of Google Maps for Android is that maps are not included in the application file. An internet connection is required to get maps and related information from Google Maps, just like with iPhone’s Google Maps application.This drawback is mitigated by an automatic map caching feature which temporarily stores recently-viewed areas. There is also a 'Download Map Area' feature in the Labs section of Google Maps. The 'Download Map Area' feature enables the user to download the road map and landmark data for an area of 10 square miles (26 km²) around any point. The user can do this action multiple times to cover as much area as desired. Google suggests that users can make use of this feature to download the map of a foreign city like Toronto before traveling to visit it, so that once the user arrives in the city of Toronto, they can refer to the pre-downloaded road map noting buildings including condos and other property styles without needing to use expensive international roaming charges. However, the downloaded map area only includes the basic road map and its landmark labels. Google notes that even after you download a map area, "you still need a data connection to see satellite view and 3D buildings, search for Places and get directions.
