[MetaCRS] EPSG New Release

[Dean C.Mikkelsen]

Hi everyone,

Speaking of EPSG, there is a new release available.

The details follow:

=====================================================

ANNOUNCEMENT of availability of the online, web-enabled 
EPSG Geodetic Parameter Registry v6.15 (April, 2008)

and

RELEASE of EPSG Geodetic Parameter Dataset v6.15  (April 
15, 2008)

  

This release (Version 6.15) of the EPSG Geodetic Parameter 
Dataset comprises of data corrections and updates to the 
v6.14 release of September 2007.   The EPSG Geodetic 
Parameter Dataset is maintained by the Geodesy 
Subcommittee of the Surveying and Positioning Committee of 
the International Association of Oil and Gas Producers 
(OGP).  This version and prior archived versions may be 
downloaded without charge from www.epsg.org. The dataset 
will continue to be known as the EPSG Geodetic Parameter 
Dataset.

  

Since the previous version 6.14, the EPSG Geodetic 
Parameter Dataset is additionally made available through 
the web-enabled EPSG Geodetic Parameter Registry service 
(beta-test version) at http://www.epsg-registry.org/ (with 
link from the OGP’s main EPSG webpage, www.epsg.org.) This 
online registry supports anonymous (guest) access through 
which users may query and view the data and generate 
printable reports. It also permits the user to register 
for additional services, such as the export of the entire 
EPSG data set as GML 3.2 dictionaries.  There is no charge 
for such registration.

  

As for previous releases, the v6.15 dataset also remains 
available in two downloadable forms: either an MS Access 
database which also includes a data reporting capability, 
or as a series of SQL scripts for populating an 
alternative relational database application. There are 
different SQL scripts for various SQL variants. In each 
format, the v6.15 release is accompanied by an updated 
version of the current ReadMe file, in both PDF and MS 
Word formats.

  

The OGP plans to move from MS Access 97 to a later version 
of MS Access in the relatively near future and your 
opinion is solicited as to the most suitable MS Access 
platform. Release in MS Access 2003 is tentatively 
planned, but other options are MS Access 2007 and MS 
Access 2000/2001.  Your opinion on which of these should 
be supported is solicited.

  

New to Version 6.15 are:

·         Changes as documented in Change table records 
through 2008.028, but with actions still remaining on some 
change requests.

·         Revisions to data for China, Cuba, Eastonia, 
France, Georgia, Kuwait, Lithuania, New Zealand, Portugal, 
Spain and Sweden.

·         New data for Azerbaijan, Bermuda, Canada, 
Croatia, Cuba, France, New Zealand, Pitcairn, Portugal, 
Slovenia, United States and Uruguay.

·         Added spherical Mercator coordinate operation 
method and associated CRS as sed in popular web mapping 
and visualisation applications.

·         Added topocentric and visualisation coordinate 
operation methods.

·         Clarified the description of Vertical Offset 
coordinate operation methods to allow for height to depth 
transformations.

·         Clarified the description of reversibility of 
methods using interpolation of gridded data sets.

  

For Versions 6.13, 6.14 and 6.15, the use of the terms 
'supersede', 'retire' and 'replace' has been rationalised. 
This included structural changes to the Supersession table 
in v6.13 in which the supersession type of 'replacement' 
has been eliminated. This v6.13 rationalisation also 
included changes to the supersession type assigned to 
records within the supersession table and to remarks in 
records in other tables. The same structure remains in 
v6.14 and v6.15.  The EPSG dataset interpretation of ISO 
19135 terms is discussed in Guidance Note 7 part 1 – Use 
of the EPSG Geodetic Parameter Dataset.

  

In addition to the above data content changes, the “Use of 
the Data” rules were also clarified in v6.13 and expanded 
to facilitate increased use of the EPSG dataset in third 
party software.  See the Readme file or associated online 
documentation for additional details.
