NEUE EPSG-VERSION 6.15 publiziert !

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.
