geocrs
Geographic coordinate reference system object
Description
A geographic coordinate reference system (CRS) provides information that assigns latitude, longitude, and height coordinates to physical locations. Geographic CRSs consist of a datum, a prime meridian, and an angular unit of measurement.
Projected CRSs consist of a geographic CRS and several parameters that are used to
transform coordinates to and from the geographic CRS. For more information about projected
CRSs, see projcrs
.
Creation
There are several ways to create geographic CRS objects, including:
Import raster data using functions such as
readgeoraster
orwmsread
, and then query theGeographicCRS
property of the returned raster reference object.Get information about a shapefile using the
shapeinfo
function, and then query theCoordinateReferenceSystem
field of the returned structure.Access the geographic CRS of a projected CRS by querying the
GeographicCRS
property of aprojcrs
object.Use the
geocrs
function (described here).
