Tides data is strongly needed especially on Indonesian Coastal Environment mapping to achieve its accuracy. Usually, tides data derived from direct or indirect measurement. From palm observation, the tides data collected directly. Indirect measurement takes the advantages of altimetry satellite, where tides data collection carried in a shorter time and large area. In the supremacy of using altimetry satellite, we could obtain tides information not only in coastal but also in open waters. Study of altimetry data is required to prove whether tides components resulted represent real tides condition in coastal or vice versa. Finding out the linkage between tidal components resulted from Jason-1 altimetry satellite became the aim of this paper. Cross-over analysis method ran to examine the linkage between each tidal constituent. The tidal correlation value determined the accuracy of amplitude result from altimetry satellite. Gaussian Distribution played a role in determining the status of cross-over point data. The amplitude will point whether the cross-over point will continue to involve in tidal amplitude gridding process. The higher value of cross-over amplitude related to influence subsists between tides components in which the emerging values do not represent each tidal constituent itself.
