Help & Useful Tips
Using the Interactive Map
Our Interactive Map interface uses Google Maps to display our historic map resources along with modern maps.
Zooming: To zoom in or out, use the two finger pinching and spreading motions. Depending on your mobile device, there may also be dedication + and - buttons that you can tap to zoom in and out.
Panning: To pan (move) around the map, simply drag the map with your finger.
Changing Maps: To change which map layers are displayed, tap the gear icon at the top of the window. Tap the checkbox for any of the map layers to turn it on or off. You may adjust the visibility (opacity) of the parcels layer by tapping on the dropdown box and choosing the desired percentage (100% is fully visible, 0% is fully transparent).
View Parcel Details: You can view information on any parcel by tapping on the desired property. A window will appear with some information; you may view additional information (when available) by tapping the "details" link.
