Reprojects attributes from one coordinate system to another using the CS-MAP library.
Choose from recently accessed coordinate systems, or click the browse button to access the Coordinate System Gallery.
Specifies what geographic transformation will be used to convert points from the source datum to the destination. If set to <Auto>or left blank, FME will attempt to choose an appropriate transformation. If set to <None>, the NULL_FME transformation will be used which does not alter the value of any coordinates.
Note: <Auto> and <None> are GUI only values. Use the alternative blank string and NULL_FME respectively when passing in as an attribute.
This parameter determines how Z values will be handled.
Geocentric or ellipsoid height -> Orthometric height: Z values will be converted from ellipsoid height to orthometric (sea level) height given the specified geoid height grid. Z units will be the same as the horizontal units (or meters, for geographic coordinate systems). If the source coordinate system is geocentric, coordinates will be converted to geographic+ellipsoid height before being processed.
Example: [Geocentric (datum A) ->] LL + ellipsoid height (datum A) -> LL + ellipsoid height (datum B) -> LL + orthometric height (datum B)
Orthometric height -> Geocentric or ellipsoid height: Z values will be converted from orthometric (sea level) height to ellipsoid height given the specified geoid height grid. Z units will be the same as the horizontal units (or meters, for geographic coordinate systems). If the destination coordinate system is geocentric, coordinates will be converted to geocentric after being processed.
Example: LL + orthometric height (datum A) -> LL + ellipsoid height (datum A) -> LL + ellipsoid height (datum B) [-> Geocentric (datum B)]
This parameter determines which geoid height grid will be applied to the Z values.
Choose which X, Y, and Z attributes to reproject.
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
