Handling CRS/WKT

Description

in favour of fmesher::fm_wkt() and related methods.

Get and set CRS object or WKT string properties.

Usage

inla.wkt_is_geocent(wkt)

inla.crs_is_geocent(crs)

inla.wkt_get_ellipsoid_radius(wkt)

inla.crs_get_ellipsoid_radius(crs)

inla.wkt_set_ellipsoid_radius(wkt, radius)

inla.crs_set_ellipsoid_radius(crs, radius)

inla.wkt_unit_params()

inla.wkt_get_lengthunit(wkt)

inla.wkt_set_lengthunit(wkt, unit, params = NULL)

inla.crs_get_wkt(crs)

inla.crs_get_lengthunit(crs)

inla.crs_set_lengthunit(crs, unit, params = NULL)

Arguments

Value

For inla.wkt_unit_params, a list of named unit definitions

For inla.wkt_get_lengthunit, a list of length units used in the wkt string, excluding the ellipsoid radius unit.

For inla.wkt_set_lengthunit, a WKT2 string with altered length units. Note that the length unit for the ellipsoid radius is unchanged.

For inla.crs_get_wkt, WKT2 string.

For inla.crs_get_lengthunit, a list of length units used in the wkt string, excluding the ellipsoid radius unit. (For legacy PROJ4 code, the raw units from the proj4string are returned, if present.)

For inla.crs_set_lengthunit, a sp::CRS object with altered length units. Note that the length unit for the ellipsoid radius is unchanged.

For inla.wkt_unit_params, a list of named unit definitions

For inla.wkt_get_lengthunit, a list of length units used in the wkt string, excluding the ellipsoid radius unit.

For inla.wkt_set_lengthunit, a WKT2 string with altered length units. Note that the length unit for the ellipsoid radius is unchanged.

For inla.crs_get_wkt, WKT2 string.

For inla.crs_get_lengthunit, a list of length units used in the wkt string, excluding the ellipsoid radius unit. (For legacy PROJ4 code, the raw units from the proj4string are returned, if present.)

For inla.crs_set_lengthunit, a sp::CRS object with altered length units. Note that the length unit for the ellipsoid radius is unchanged.
