As you probably noticed, PolarView is supplied with a “copyright-safe” set of tides & currents for the US waters from NOAA. I often get asked for tidal data covering other parts of the world. The answer is that there is no “official” set of constituents that Polar Navy Co can provide for legal and organizational reasons.
That said, a number of TCD databases covering various areas of the world are available from various sources. Some of these files are collected and can be downloaded from this page. Please note that these are not in any way official, or guaranteed to be correct. They come from sources unknown and their quality can vary greatly. Also note that copyright status of such data may be not well established. Some of this data can only be legally used with free software. YMMV, as they say.
