get_sea: Determines Sea Names for Points Located in a Marine Area.
In mcmventura/stlocationqc: C3S Quality Control of Meteorological Stations Location

Description Usage Arguments Details References Examples

Given a list of geographic coordinates in marine areas of the world, determines the geographical name of the sea, ocean, bay, gulf, fjord, etc. were each one of the points is located. Uses a SpatialPolygonsDataFrame with 10 m precision containing the polygons and sea names, which covers most of the marine territories on Earth.

1	get_sea(icoords)

icoords

data frame with three columns: id | lon | lat where: 'id' is the row identifier for the coordinates in the original list of coordinates, 'lon' is the longitude in the range (-180, +180) and 'lat' is the latitude. Both coordinates are in decimal degrees.

Input:

The output of get_country - 'miss_countries' -, or the output of get_country_shoreline, - 'miss_countries_sh' -, i.e., a data frame with three columns: id | lon | lat.

Output:

A text file with the points for which a sea name was determined, if they exist. That file has the following header: id | lon | lat | sea.
A text file with the missing sea names, if they exist.
A .RData file with the output data frame(s). The data frame 'seas' has the header id | lon | lat | sea. The eventual data frame 'miss_seas' has the header id | lon | lat.

## First run

## Or
test_geocoord(coords = eraclim_uao_fp)
## Then run sequentially
