How to compare high-resolution aerial imagery across two capture dates

The Compare tool lets you view high-resolution aerial imagery of a location across two different capture dates. This makes it easy to track how a property or area has changed over time.

By default, the map displays the most recent available capture. With Compare, you can select two different capture dates and use a slider to see what's changed.

Note: To use the Compare tool, high-resolution aerial imagery must be turned on. Properties can not be selected when using this tool.
