Systems and methods for surveying using a GNSS device are provided. In one example method, a GNSS device may be used to determine the location of points along a path and to add those points to a set of points representing the path. When adding each point, the device may determine if the point represents a new point or a previously measured point. If the point is a new point, the device may add the point to the set of points. If the point is a previously measured point, the device may display one or more previously measured points to allow the user to select which previously measured point corresponds to the point currently being measured. The user may select a previously measured point and a point may be added to the set of points using the location of the selected previously measured point.
