Abstract

A support for geomatic equipment such as a geomatic pole has feet which facilitate stability of the pole. The feet are constructed to resist forces applied along legs of the support to which they are connected in both directions, including forces which tend to lift the feet upward. The foot is formed to readily penetrate certain surfaces and to resist withdrawal from the surfaces after penetration. In one embodiment, a fixed connection to the underlying surface may be achieved. The foot is also constructed to resist rotation of the foot and leg to which it is attached which could cause instability of the support.
