Oregon Maps, Aerial photos, and GIS data

[PDXnative]

To really help in finding information about an area, there are many useful tools online that can give you maps, aerial photos, and GIS (geographical information systems) data about areas and properties. It is also fun to see what your house is worth or see what your neighbors paid for their house.

Here are some useful links:

For Oregon and everywhere else:
Google Maps
Google Earth

For Portland: (this also shows crime and other stats)
