Milwaukee County has a powerful online mapping tool which integrates a fully featured Geographic Information System, GIS. There are many layers that give useful information including historic aerial photos of the city and county going back to 1936. The 1951 aerial photo layer was completed in January which shows a highly detailed view of the entire county. Hopefully later this year an additional aerial photo set from 1928 will be included.

Also for those interested, there is up to date housing foreclosure information updated at the end of the year. As with any government GIS map, finding information on property owners is a simple click away. There is a little learning curve for people unfamiliar with using GIS maps but you cannot break it so play with it to learn.
