Abstract
The invention is directed to targets for use where precise alignment and location measurements on an object is required. Several embodiments of the invention are described. The targets have at least a portion of their outer surface curvilinear. The target is supported on a convex supporting surface on a support body. Various configured single targets and multiple targets are described for use on flat as well as curved surfaces. Some of the targets have either non-reflective or reflective target surfaces. The various embodiments of the ball targets are used in conjunction with either optical or laser theodolites or the like to preform the required location measurements.
