create_grid: Creates a continious grid

In ptaconet/rtunaatlas: IRD Sardara Tuna Atlas R facilities

Description

Create a continious (regular) geospatial grid

Usage

create_grid(latmin,latmax,lonmin,lonmax,resolution,crs,centred)

Arguments

latmin	real smallest latitude for the spatial grid in degree (range: -90 to 90)
latmax	real biggest latitude wanted for the spatial grid in degree (range: -90 to 90)
lonmin	real smallest longitude for the spatial grid in degree (range: -180 to 180)
lonmax	real biggest longitude wanted for the spatial grid in degree (range: -180 to 180)
resolution	real spatial resolution of the grid in degree
crs	character string a character string of projection arguments; the arguments must be entered exactly as in the PROJ.4 documentation.
centred	boolean TRUE for a grid centred on zero. default is TRUE

Details

The default CRS is EPSG 4326: "+init=epsg:4326 +proj=longlat +datum=WGS84"

Value

A sf object (package : sf) based on input parameters and composed by square polygons.
