Tide Constituent Database (TCD) library (header file)
libtcd provides a software API for reading and writing Tide Constituent Database (TCD) files.
The TCD file format and schema are used by XTide to retrieve constituent definitions (speeds, equilibrium arguments, and node factors), harmonic constants, subordinate station offsets and associated metadata for use in generating tide predictions.
