Using the ArcGIS.com viewer you can add DC’s Vector Property layers. After clicking on Make a Map, click the Add button. Search property and land dc and add either of the returns. Another layer to add is OwnerPoly. By using this mash-up method you ensure you’re getting the best data available. The ArcGIS.com viewer makes it easy to discover and mash-up other Web services into a new map.
ArcGIS Explorer Online - http://explorer.arcgis.com/ has a similar look and feel and some of the same capabilities as the downloadable desktop version, but it's a lightweight version built using Silverlight that runs in a browser. Explorer Online offers some additional functions and capabilities. You can also add dc data to ArcGIS Explorer Online.
