Class CS_DatumType

java.lang.Object
  org.opengis.cs.CS_DatumType

All Implemented Interfaces:

java.io.Serializable

public class CS_DatumType

extends java.lang.Object

implements java.io.Serializable

Type of the datum expressed as an enumerated value. The enumeration is split into ranges which indicate the datum's type. The value should be one of the predefined values, or within the range for local types. This will allow OGC to coordinate the addition of new interoperable codes.

Field Summary

static int	CS_HD_Classic These datums, such as ED50, NAD27 and NAD83, have been designed to support horizontal positions on the ellipsoid as opposed to positions in 3-D space.
static int	CS_HD_Geocentric A geocentric datum is a "satellite age" modern geodetic datum mainly of global extent, such as WGS84 (used in GPS), PZ90 (used in GLONASS) and ITRF.
static int	CS_HD_Max Highest possible value for horizontal datum types.
static int	CS_HD_Min Lowest possible value for horizontal datum types.
static int	CS_HD_Other Unspecified horizontal datum type.

static int	CS_LD_Min Lowest possible value for local datum types.
static int	CS_VD_AltitudeBarometric The vertical datum of altitudes or heights in the atmosphere.
static int	CS_VD_Depth This attribute is used to support the set of datums generated for hydrographic engineering projects where depth measurements below sea level are needed.
static int	CS_VD_Ellipsoidal A vertical datum for ellipsoidal heights that are measured along the normal to the ellipsoid used in the definition of horizontal datum.

CS_HD_Other

public static final int CS_HD_Other

Unspecified horizontal datum type. Horizontal datums with this type should never supply a conversion to WGS84 using Bursa Wolf parameters.

CS_HD_Classic

public static final int CS_HD_Classic

These datums, such as ED50, NAD27 and NAD83, have been designed to support horizontal positions on the ellipsoid as opposed to positions in 3-D space. These datums were designed mainly to support a horizontal component of a position in a domain of limited extent, such as a country, a region or a continent.

CS_HD_Geocentric

public static final int CS_HD_Geocentric

A geocentric datum is a "satellite age" modern geodetic datum mainly of global extent, such as WGS84 (used in GPS), PZ90 (used in GLONASS) and ITRF. These datums were designed to support both a horizontal component of position and a vertical component of position (through ellipsoidal heights). The regional realizations of ITRF, such as ETRF, are also included in this category.

CS_VD_Ellipsoidal

public static final int CS_VD_Ellipsoidal

CS_VD_AltitudeBarometric

public static final int CS_VD_AltitudeBarometric

The vertical datum of altitudes or heights in the atmosphere. These are approximations of orthometric heights obtained with the help of a barometer or a barometric altimeter. These values are usually expressed in one of the following units: meters, feet, millibars (used to measure pressure levels), or theta value (units used to measure geopotential height).

CS_VD_Normal

public static final int CS_VD_Normal

A normal height system.

Constant Field Values

CS_VD_GeoidModelDerived

public static final int CS_VD_GeoidModelDerived

A vertical datum of geoid model derived heights, also called GPS-derived heights. These heights are approximations of orthometric heights (H), constructed from the ellipsoidal heights (h) by the use of the given geoid undulation model (N) through the equation: H=h-N.

CS_VD_Depth

public static final int CS_VD_Depth

This attribute is used to support the set of datums generated for hydrographic engineering projects where depth measurements below sea level are needed. It is often called a hydrographic or a marine datum. Depths are measured in the direction perpendicular (approximately) to the actual equipotential surfaces of the earth's gravity field, using such procedures as echo-sounding.
