additionalTransformPaths

additionalTransformPaths: undefined | GeodeticTransformPathProps[]

The optional list of transformation paths to other datum. These should only be used if the path to these datum is not included in the transforms property definition of the transformation to WGS84. It should not be used either if the transformation to the datum can be infered from the concatenation of their individual paths to WGS84. These should be used to express an alternate shortcut path that is inherent to the nature of the datum. As an example it is required to represent the transformation from NAD27 to NAD83/2011 since NAD83/2011 is coincident to WGS84 yet the NAD27 datum to WGS84 path only includes transformation to NAD83, making the path of transforms to NAD83/2011 not related to the available paths to WGS84.
