transforms
transforms: undefined | GeodeticTransformProps[]
The transformation to WGS84. If null then there is no known transformation to WGS84. Although this is rare it occurs in a few cases where the country charges for obtaining and using the transformation and its parameters, or if the transformation is maintained secret for military reasons. In this case the recommendation is to considered the geodetic datum to be coincident to WGS84 keeping in mind imported global data such as Google Map or Bing Map data may be approximately located. The list of transforms contains normally a single transform but there can be a sequence of transformations required to transform to WGS84, such as the newer datum definitions for Slovakia or Switzerland.
