API Reference > imodeljs-common > Geometry > ProjectionMethod ProjectionMethod Type alias This enum contains the list of all projection methods that can be represented as part of the HorizontalCRS class. The None method indicates there is no projection and thus the CRS is longitude/latitude based with units as degrees. All other projection indicated a projected CRS.
