compute_tidal_currents.py

Calculates tidal currents for an input file following [Egbert2002]
Can use OTIS format tidal solutions provided by Ohio State University and ESR
Can use Finite Element Solution (FES) models provided by AVISO
Can read and write ascii, netCDF4, HDF5, parquet and geotiff formats

Calling Sequence

--variables : @after

for csv files: the order of the columns within the file
for HDF5, netCDF4 and parquet files: time, y, x and data variable names

--type -t : @after

'drift': drift buoys or satellite/airborne altimetry (time per data point)
'grid': spatial grids or images (single time for all data points)
'time series': station locations with multiple time values

--epoch -e : @after

'days since 1858-11-17T00:00:00' (default Modified Julian Days)

--deltatime -d : @after

can be set to 0 to use exact calendar date from epoch

--standard -s : @after

'UTC': Coordinate Universal Time
'GPS': GPS Time
'LORAN': Long Range Navigator Time
'TAI': International Atomic Time
'datetime': formatted datetime string in UTC

--projection : @after

4326: latitude and longitude coordinates on WGS84 reference ellipsoid

--cutoff -c : @after

set to 'inf' to extrapolate for all points
