Interface for Objects which can be described by their features. An Object is described by a Datum as a List of categorical features. (For features which have numeric values, see {@link RVFDatum}. These objects can also be Serialized (for insertion into a file database). @author Sepandar Kamvar (sdkamvar@stanford.edu) @author Sarah Spikes (sdspikes@cs.stanford.edu) (Templatization) @param < L> The type of the labels in the Datum @param < F> The type of the features in the Datum

org.openstreetmap.josm.data.projection.datum.Datum
Represents a geodetic datum. Basically it provides conversion functions from and to the WGS84 datum.
org.osgeo.proj4j.datum.Datum
A class representing a geodetic datum.
A geodetic datum consists of a set of reference points on or in the Earth, and a reference {@link Ellipsoid} giving an approximation to the true shape of the geoid.
In order to transform between two geodetic points specified on different datums, it is necessary to transform between the two datums. There are various ways in which this datum conversion may be specified:
- A 3-parameter conversion
- A 7-parameter conversion
- A grid-shift conversion
In order to be able to transform between any two datums, the parameter-based transforms are provided as a transform to the common WGS84 datum. The WGS transforms of two arbitrary datum transforms can be concatenated to provide a transform between the two datums.
Notable datums in common use include {@link #NAD83} and {@link #WGS84}.
