Measurements of tidal currents by means of present current-meters at such a deep and rapid one as the Akashi straits are often in failing or inaccuracy owing to the difficulty of anchor-hold. So, for the survey of tidal currents in the Akashi straits, we attempted the two ways by utilizing of techniques and the implements about the aero-photogrammetry. One way is the vector-method of pursuing many drifting buoys, another way is the parallax-method by applying the Cameron's effects. As the results of adopting of two photogrammetric methods, we could show the simultaneous distributions of detailed currents, more 9 knots, at outer sea-area of narrowest part of the straits.
