Welcome to TopoNC, a database that allows keyword searching for places, features, and quadrangle names within 7.5 topo maps for the state of North Carolina.

To begin searching, click “Enter Database” on the left-side column. The default is to the Basic Search screen that allows you to type in a keyword.

On the right side of the screen, you may choose Advanced Search. This function allows you to type in a keyword for either a feature name or a quadrangle name. You may then limit to county or feature type.

The results include county, quadrangle name, latitude and longitude, and a hyperlink for Joyner’s print holdings of 7.5 topographic maps for the quadrangle.

In addition, a Digital Raster Graphic of the topographic map from TerraServer is included.


North Carolina is divided into 953 quadrangles representing 7.5’ latitude by 7.5’ longitude.
