API Reference > imodeljs-common > Geometry > ProjectionProps ProjectionProps Interface This class encapsulates the projection of the CRS. The projection relies on a projection method and a set of projection parameters specific to projection method selected. Implemented by Projection Properties Name Type Description affine undefined | AffineTransformProps The definition of the affine post-transformation for Transverse Mercator and Lambert Conformal Conic with post-affine projections azimuth undefined | number Azimuth. centralMeridian undefined | number The Central Meridian. centralPointLatitude undefined | number Latitude of the central point. centralPointLongitude undefined | number Longitude of the central point. danishSystem34Region undefined | DanishSystem34Region The Danish zone for Danish projections. elevationAboveGeoid undefined | number The elevation of the origin of the projection above the geoid. falseEasting undefined | number The False Easting of the projection. falseNorthing undefined | number The False Northing of the projection. geoidSeparation undefined | number The geoid separation. hemisphere undefined | HemisphereEnum The hemisphere for Universal Transverse Mercator projection. latitudeOfOrigin undefined | number The latitude of origin of the projection. longitudeOfOrigin undefined | number Longitude of origin of the projection. method ProjectionMethod The projection method. point1Latitude undefined | number Latitude of the first alignment point for some Oblique Mercator and Krovak projections. point1Longitude undefined | number Longitude of the first alignment point for some Oblique Mercator and Krovak projections. point2Latitude undefined | number Latitude of the second alignment point for some Oblique Mercator projections. point2Longitude undefined | number Longitude of the second alignment point for some Oblique Mercator projections. scaleFactor undefined | number The scale reduction factor applied at origin. standardParallel undefined | number Standard parallel for projection that only use one. standardParallel1 undefined | number The first standard parallel at which the cone crosses the ellipsoid. standardParallel2 undefined | number The second standard parallel at which the cone crosses the ellipsoid. zoneNumber undefined | number The UTM zone number.
