Covert grid reference to latitude and longitude

Usage

gr2gps_latlon(gridref, precision = NULL, projection = "OSGB", centre = TRUE)

Arguments

gridref

a vector of strings giving grid references to be changed

precision

gives the precision of the grid references. Must be of the same length as gridref. precision is given in meters as a numeric i.e. 10km square = 10000, 1km square = 1000. If NULL then the function tries to work out the precision itself.

projection

specifies the projection of the input and can either be "OSGB" or "OSNI". Defaults to "OSGB"

centre

If TRUE the coordinates for the centre of the cell are given else if FALSE the coordinates for the bottom left corner are given.

Value

A dataframe of results are returned
