Properties

latestWkid

latestWkid: undefined | number

Latest well known id. This optional property allows updated wkid values to be leveraged when standards change

wkid

wkid: undefined | number

Well known id. This generally corresponds to an EPSG code or an ESRI wkid number

wkt

wkt: undefined | string

Well known type.
