Abstract: If f is a continuous mapping of finite Geöcze area from a polyhedral region $ X \subset {R^k}$ into $ {R^n},2 \leqq k \leqq n$, then, under suitable hypotheses, one can associate with f, by means of the Cesari-Weierstrass integral, a current valued measure T over the middle space of f. In particular, if either $ k = 2$ or the $ k + 1$-dimensional Hausdorff measure of $ f(X)$ is zero, then T is essentially the same as a current valued measure defined by H. Federer and hence serves to describe the tangential properties of f and the multiplicities with which f assumes its values. Further, the total variation of T is equal to the Geöcze area of f.
