Class SpatialReference

java.lang.Object

org.gdal.osr.SpatialReference

All Implemented Interfaces:

Cloneable

public class SpatialReference
extends Object
implements Cloneable

This class represents an OpenGIS Spatial Reference System, and contains methods for converting between this object organization and well known text (WKT) format. This object is reference counted as one instance of the object is normally shared between many Geometry objects.

The SpatialReference class is a binding for the C++ OGRSpatialReference class.

Normally application code can fetch needed parameter values for this SRS using GetAttrValue(), but in special cases the underlying parse tree (or OGR_SRSNode objects) can be accessed more directly.

See the tutorial for more information on how to use this class.

Parameters:

name - full path to attribute to be set. For instance "PROJCS|GEOGCS|UNITS".

value - value to be assigned to node, such as "meter". This may be null if you just want to force creation of the intermediate path.

SetWellKnownGeogCS

public int SetWellKnownGeogCS(String name)

Set a GeogCS based on well known name.

This may be called on an empty OGRSpatialReference to make a geographic coordinate system, or on something with an existing PROJCS node to set the underlying geographic coordinate system of a projected coordinate system.

The following well known text values are currently supported:

• "WGS84": same as "EPSG:4326" but has no dependence on EPSG data files.
• "WGS72": same as "EPSG:4322" but has no dependence on EPSG data files.
• "NAD27": same as "EPSG:4267" but has no dependence on EPSG data files.
• "NAD83": same as "EPSG:4269" but has no dependence on EPSG data files.
• "EPSG:n": where n is the code a Geographic coordinate reference system.

Parameters:

name - name of well known geographic coordinate system.

Returns:

0 on success. Otherwise throws a RuntimeException() (or an error code if DontUseExceptions() has been called).

SetFromUserInput

public int SetFromUserInput(String name,
 Vector options)

SetFromUserInput

public int SetFromUserInput(String definition)

Set spatial reference from various text formats.

This method will examine the provided input, and try to deduce the format, and then use it to initialize the spatial reference system. It may take the following forms:

1. Well Known Text definition - passed on to importFromWkt().
2. "EPSG:n" - number passed on to importFromEPSG().
3. "EPSGA:n" - number passed on to importFromEPSGA().
4. "AUTO:proj_id,unit_id,lon0,lat0" - WMS auto projections.
5. "urn:ogc:def:crs:EPSG::n" - ogc urns
6. PROJ.4 definitions - passed on to importFromProj4().
7. filename - file read for WKT, XML or PROJ.4 definition.
8. well known name accepted by SetWellKnownGeogCS(), such as NAD27, NAD83, WGS84 or WGS72.
9. WKT (directly or in a file) in ESRI format should be prefixed with ESRI:: to trigger an automatic morphFromESRI().

It is expected that this method will be extended in the future to support XML and perhaps a simplified "minilanguage" for indicating common UTM and State Plane definitions.

This method is intended to be flexible, but by it's nature it is imprecise as it must guess information about the format intended. When possible applications should call the specific method appropriate if the input is known to be in a particular format.

Parameters:

definition - text definition to try to deduce SRS from.

Returns:

0 on success. Otherwise throws a RuntimeException() (or an error code if DontUseExceptions() has been called).

CopyGeogCSFrom

public int CopyGeogCSFrom(SpatialReference src_srs)

Parameters:

src_srs - the spatial reference to copy the GEOGCS information from.

Returns:

0 on success. Otherwise throws a RuntimeException() (or an error code if DontUseExceptions() has been called).

This will create the TOWGS84 node as a child of the DATUM. It will fail if there is no existing DATUM node. Unlike most OGRSpatialReference methods it will insert itself in the appropriate order, and will replace an existing TOWGS84 node if there is one.

The parameters have the same meaning as EPSG transformation 9606 (Position Vector 7-param. transformation).

Parameters:

dfDX - X child in meters.

dfDY - Y child in meters.

dfDZ - Z child in meters.

dfEX - X rotation in arc seconds (optional, defaults to zero).

 double dfConvertToRadians)

Set geographic coordinate system.

This method is used to set the datum, ellipsoid, prime meridian and angular units for a geographic coordinate system. It can be used on it's own to establish a geographic spatial reference, or applied to a projected coordinate system to establish the underlying geographic coordinate system.

Parameters:

pszGeogName - user visible name for the geographic coordinate system (not to serve as a key).

pszDatumName - key name for this datum. The OpenGIS specification lists some known values, and otherwise EPSG datum names with a standard transformation are considered legal keys.

pszSpheroidName - user visible spheroid name (not to serve as a key)

dfSemiMajor - the semi major axis of the spheroid.

dfInvFlattening - the inverse flattening for the spheroid. This can be computed from the semi minor axis as 1/f = 1.0 / (1.0 - semiminor/semimajor).

Returns:

0 on success. Otherwise throws a RuntimeException() (or an error code if DontUseExceptions() has been called).

ImportFromProj4

public int ImportFromProj4(String proj4)

Import PROJ.4 coordinate string.

The OGRSpatialReference is initialized from the passed PROJ.4 style coordinate system string. In addition to many +proj formulations which have OGC equivalents, it is also possible to import "+init=epsg:n" style definitions. These are passed to importFromEPSG(). Other init strings (such as the state plane zones) are not currently supported.

 Example:
   pszProj4 = "+proj=utm +zone=11 +datum=WGS84"
 

Some parameters, such as grids, recognized by PROJ.4 may not be well understood and translated into the OGRSpatialReference model. It is possible to add the +wktext parameter which is a special keyword that OGR recognizes as meaning "embed the entire PROJ.4 string in the WKT and use it literally when converting back to PROJ.4 format".

 For example:
 "+proj=nzmg +lat_0=-41 +lon_0=173 +x_0=2510000 +y_0=6023150 +ellps=intl
  +units=m +nadgrids=nzgd2kgrid0005.gsb +wktext"

will be translated as :

 PROJCS["unnamed",
    GEOGCS["International 1909 (Hayford)",
        DATUM["unknown",
            SPHEROID["intl",6378388,297]],
        PRIMEM["Greenwich",0],
        UNIT["degree",0.0174532925199433]],
    PROJECTION["New_Zealand_Map_Grid"],
    PARAMETER["latitude_of_origin",-41],
    PARAMETER["central_meridian",173],
    PARAMETER["false_easting",2510000],
    PARAMETER["false_northing",6023150],
    UNIT["Meter",1],
    EXTENSION["PROJ4","+proj=nzmg +lat_0=-41 +lon_0=173 +x_0=2510000
               +y_0=6023150 +ellps=intl  +units=m +nadgrids=nzgd2kgrid0005.gsb +wktext"]]

Returns:

0 on success. Otherwise throws a RuntimeException() (or an error code if DontUseExceptions() has been called).

ImportFromESRI

public int ImportFromESRI(Vector ppszInput)

Import coordinate system from ESRI .prj format(s).

This function will read the text loaded from an ESRI .prj file, and translate it into an OGRSpatialReference definition. This should support many (but by no means all) old style (Arc/Info 7.x) .prj files, as well as the newer pseudo-OGC WKT .prj files. Note that new style .prj files are in OGC WKT format, but require some manipulation to correct datum names, and units on some projection parameters. This is addressed within importFromESRI() by an automatic call to morphFromESRI().

Currently only GEOGRAPHIC, UTM, STATEPLANE, GREATBRITIAN_GRID, ALBERS, EQUIDISTANT_CONIC, and TRANSVERSE (mercator) projections are supported from old style files.

At this time there is no equivalent exportToESRI() method. Writing old style .prj files is not supported by OGRSpatialReference. However the morphToESRI() and exportToWkt() methods can be used to generate output suitable to write to new style (Arc 8) .prj files.

Parameters:

ppszInput - vector of strings containing the definition.

Returns:

0 on success. Otherwise throws a RuntimeException() (or an error code if DontUseExceptions() has been called).

ImportFromEPSG

public int ImportFromEPSG(int nCode)

Initialize SRS based on EPSG GCS or PCS code.

This method will initialize the spatial reference based on the passed in EPSG GCS or PCS code. The coordinate system definitions are normally read from the EPSG derived support files such as pcs.csv, gcs.csv, pcs.override.csv, gcs.override.csv and falling back to search for a PROJ.4 epsg init file or a definition in epsg.wkt.

These support files are normally searched for in /usr/local/share/gdal or in the directory identified by the GDAL_DATA configuration option. See CPLFindFile() for details.

This method is relatively expensive, and generally involves quite a bit of text file scanning. Reasonable efforts should be made to avoid calling it many times for the same coordinate system.

This method is similar to importFromEPSGA() except that EPSG preferred axis ordering will *not* be applied for geographic coordinate systems. EPSG normally defines geographic coordinate systems to use lat/long contrary to typical GIS use).

Parameters:

nCode - a GCS or PCS code from the horizontal coordinate system table.

Returns:

0 on success. Otherwise throws a RuntimeException() (or an error code if DontUseExceptions() has been called).

ImportFromEPSGA

public int ImportFromEPSGA(int arg)

ImportFromPCI

public int ImportFromPCI(String proj,
 String units,
 double[] prjParams)

Import coordinate system from PCI projection definition.

PCI software uses 16-character string to specify coordinate system and datum/ellipsoid. You should supply at least this string to the importFromPCI() function.

Parameters:

proj - string containing the definition. Looks like "pppppppppppp Ennn" or "pppppppppppp Dnnn", where "pppppppppppp" is a projection code, "Ennn" is an ellipsoid code, "Dnnn" --- a datum code.

units - Grid units code ("DEGREE" or "METRE"). If null, "METRE" will be used.

prjParams - Array of 17 coordinate system parameters:

 [0]  Spheroid semi major axis
 [1]  Spheroid semi minor axis
 [2]  Reference Longitude
 [3]  Reference Latitude
 [4]  First Standard Parallel
 [5]  Second Standard Parallel
 [6]  False Easting
 [7]  False Northing
 [8]  Scale Factor
 [9]  Height above sphere surface
 [10] Longitude of 1st point on center line
 [11] Latitude of 1st point on center line
 [12] Longitude of 2nd point on center line
 [13] Latitude of 2nd point on center line
 [14] Azimuth east of north for center line
 [15] Landsat satellite number
 [16] Landsat path number
 

Particular projection uses different parameters, unused ones may be set to zero. If null supplied instead of array pointer default values will be used (i.e., zeroes).

Returns:

0 on success. Otherwise throws a RuntimeException() (or an error code if DontUseExceptions() has been called).

ImportFromPCI

public int ImportFromPCI(String proj,
 String units)

ImportFromUSGS

public int ImportFromUSGS(int iProjSys,
 int iZone,

Import coordinate system from USGS projection definition.

This method will import projection definition in style, used by USGS GCTP software. GCTP operates on angles in packed DMS format (see CPLDecToPackedDMS() function for details), so all angle values (latitudes, longitudes, azimuths, etc.) specified in the padfPrjParams array should be in the packed DMS format.

If the datum code is negative, the first two values in the parameter array (param) are used to define the values as follows:

• If padfPrjParams[0] is a non-zero value and padfPrjParams[1] is greater than one, the semimajor axis is set to padfPrjParams[0] and the semiminor axis is set to padfPrjParams[1].
• If padfPrjParams[0] is nonzero and padfPrjParams[1] is greater than zero but less than or equal to one, the semimajor axis is set to padfPrjParams[0] and the semiminor axis is computed from the eccentricity squared value padfPrjParams[1]:

  semiminor = sqrt(1.0 - ES) * semimajor

  where

  ES = eccentricity squared

• If padfPrjParams[0] is nonzero and padfPrjParams[1] is equal to zero, the semimajor axis and semiminor axis are set to padfPrjParams[0].
• If padfPrjParams[0] equals zero and padfPrjParams[1] is greater than zero, the default Clarke 1866 is used to assign values to the semimajor axis and semiminor axis.
• If padfPrjParams[0] and padfPrjParams[1] equals zero, the semimajor axis is set to 6370997.0 and the semiminor axis is set to zero.

If a datum code is zero or greater, the semimajor and semiminor axis are defined by the datum code as found in the following table: Supported Datums:

       0: Clarke 1866 (default)
       1: Clarke 1880

argout - an already allocated array of 1 string to receive the output

Returns:

0 on success. Otherwise throws a RuntimeException() (or an error code if DontUseExceptions() has been called).

ExportToCF1

public Hashtable ExportToCF1(Vector options)

ExportToCF1

public Hashtable ExportToCF1()

ExportToCF1Units

public String ExportToCF1Units(Vector options)

ExportToCF1Units

public String ExportToCF1Units()

CloneGeogCS

public SpatialReference CloneGeogCS()

Make a duplicate of the GEOGCS node of this SpatialReference object.

Returns:

a new SRS, which becomes the responsibility of the caller.

Clone

public SpatialReference Clone()

Make a duplicate of this SpatialReference object.

Returns:

a new SRS, which becomes the responsibility of the caller.

StripVertical

public int StripVertical()

Validate

public int Validate()

Validate SRS tokens.

This method attempts to verify that the spatial reference system is well formed, and consists of known tokens. The validation is not comprehensive.

Returns:

0 on success. Otherwise throws a RuntimeException() (or an error code if DontUseExceptions() has been called).

MorphToESRI

public int MorphToESRI()

Convert in place to ESRI WKT format.

The value nodes of this coordinate system are modified in various manners more closely map onto the ESRI concept of WKT format. This includes renaming a variety of projections and arguments, and stripping out nodes note recognised by ESRI (like AUTHORITY and AXIS).

Returns:

0 on success. Otherwise throws a RuntimeException() (or an error code if DontUseExceptions() has been called).

MorphFromESRI

public int MorphFromESRI()

Convert in place from ESRI WKT format.

The value notes of this coordinate system are modified in various manners to adhere more closely to the WKT standard. This mostly involves translating a variety of ESRI names for projections, arguments and datums to "standard" names, as defined by Adam Gawne-Cain's reference translation of EPSG to WKT for the CT specification.

Returns:

0 on success. Otherwise throws a RuntimeException() (or an error code if DontUseExceptions() has been called).
