Mercer County GIS

This web application allows one to search and browse through most of the digital tax map information the county has available. Several tax map layers may be switched on or off and multiple years worth of aerial photography may be switched on or off as well. Property Record Cards, Deeds, Tax Bill Info, and Surveys may all be viewed for each parcel using the Info tools. Linear and area measurements may be taken with the Draw & Measure tool which can also be used to draw or place custom text on the map. Searches by Owner, Address, Legal Description, Tax Number, and Map Number may be performed. Use a % as a wildcard. Google StreetView is available as well. Printing is available with custom titling. You may use the standard Bookmarks to move quickly to specific areas in the county or even create your own bookmark for the session.
