projcrs
Projected coordinate reference system object
Description
A projected coordinate reference system (CRS) provides information that assigns
Cartesian x and y map coordinates to physical
locations. 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 geographic
CRSs, see geocrs
.
Creation
There are several ways to create projected CRS objects, including:
Import raster data by using
readgeoraster
, and then query theProjectedCRS
property of the returned raster reference object.Get information about a shapefile by using the
shapeinfo
function, and then query theCoordinateReferenceSystem
field of the returned structure.Use the
projcrs
function (described here).

Tips
When you compare two ProjectionParameters
objects by using the isequal
function, the function might return 0
(false
), even when the parameter values are the same. Instead, compare
ProjectionParameters
objects by comparing the projcrs
objects or by comparing the parameter values directly.
