WCS for NetCDF-CF Updates
2010-05-05: Juelich updated to the latest version
New Features and Bug Fixes
2010-03-10:
- upgraded server code to WCS version 1.1.2 requirements
- implemented minimum requirements for WCS 1.1.2
- totally restructured wcs.py in the process to be able to support new versions more easily in the future (hopefully)
- versions 1.1.0 and 1.1.1 will be treated by the same code as 1.1.2 as no real protocol differences were found in the spec documents
- introduced wcs_capabilities.conf in provider dir to provide some static but provider specific settings (Contact, Title, etc); also see inline documentation in that file
- moved providers from static to own providers dir, so that provider data is not freely accessible via static path any more
- index.html contents will now be delivered via owsutil.StringResponse
- moved logs out of static
- changed owsadmin from a tool generating static xml documents to a tool that collects all relevant metadata for realtime generation of XML responses to all requests
- metadata is saved as a pickled nested dict in "metadata.dat" in the provider dir -> completely removed template concept
- added get_range method to all relevant iso_time Time classes
- changed pync3 time filtering code to handle exact points in time and time ranges
- added very basic support for multiple CRS definitions
- introduced config.float_precision to globally set number of digits that floats should be rounded to before comparing them
- added config options for supported formats and CRSs to be announced in responses
- updated inline documentation
- moved ows_name, wcs_name, etc. from owsadmin to owsutil
- updated ExceptionReport generation
- owsparser will not mask ";" characters any more as they should be escaped (%3B) if they are not meant to be interpreted by the parser
2010-04-02:
- Added more query unit tests.
2010-04-05:
- Upgraded to NetCDF 4 library. This version allows cubes bigger than 2 GB to be used as data source.
2010-04-07:
- Internal improvements in ISO 8609 time parsing, correctly rejecting time zone information from full dates without time.
- Darcs update: upgraded the repository format from the original to darcs-2. New darcs access requires darcs 2
2010-04-09:
- Homepages of the service and the providers are now redirected properly, so the html documents can use relative addresses for images and other hyperlinks.
- Added real W3C-Schema based XML validation for Capabilities and Coverage Descriptions, fixed automated creation of them.
2010-04-14:
- Fixed NCML interpretation to avoid accumulation of rounding errors when creating values for dimension variables.
- Allowed querying without bbox. The spec requires either time or bbox filter.
2010-04-15:
- Re-enabled month, day_of_week, and hour_of_day filters to allow queries like: every noon hour of every weekend in every summer month. This is a non-standard extension.
- switched from standard python urlparse to own version, to allow semicolon to be used as a separator as it is used in specs.
2010-04-27
- Optimization to allow big queries: 500 MB cubes used to cause out of memory exception.
- Optimized datafed client to do big aggregations with multiple small queries. This enables aggregation of multi-gigabyte queries.
2010-04-29:
- Fix to allow dimensions to have only one coordinate.
