Since Rob has committed his precipitation spatial interpolation, the 2D_interpolation reference result had to be updated. Several members in filter classes could be made const/static/private.

New warnings have been tried to detect variable shadowing (one variable declared with the same name as another one), alignement issues, etc. This produces very verbose output (not all warnings are legitimate) but allowed to fix lots of cases of misalignement and shadowing issues. These options have been left in the CMakeLists but NOT enabled (since these warnings are not so easy to interpret).

The last filters that had not been ported to the new filtering infrastructure have been ported and their documentation updated. All filters now use window specifications (instead of vector of pointers). The misleading filter argument "index" (for parameter type) has been renamed as "param" for all filters. The use of "unsigned int" for looping over vectors has been replaced by "size_t". The old "soft" behavior for the filters has been restored (ie: if not soft, a point that can not be checked by the filter is deleted).

A few more "consts" have been added.

This is the new implementation of the filters' windowing scheme. Now, specifying 4 points and 6 hours will guarantee that at least 4 points are in the window AND 6 hours, otherwise it returns unsuccessfully. The run time penalty is ~4% compared to the previous implementation. Since it first builds the window specifications (start and end index), it is possible to directly call this window specification, skipping the building of a vector of pointers. For the MeanAvg filter, this makes the run time penalty go down to 3.3% on a 6 hours window (with hourly data).

First correct implementation of the filtering windows. This is not active yet as it only provides window specifications. But it properly fulfills both the number of points criteria and the time span criteria.

A new method, getExtension() has been added to IOUtils in order to return the extension of a given filename. This is used by the SMETIO and SNIO plugins to automatically add the proper extension to input file names if they don't already have one.

The Median Average Deviation filter has been ported (and validated) to the new filtering infrastructure.

Several error messages have been improved.

Performance boost: Redesign of class MeteoData. The individual public double members like tss, ta, rh have been removed and instead of the rather complicated internal representation with the help of std::map and pointers, the MeteoData object now holds all its important information in one double vector (meteo data) and one string vector (parameter names). Thus the overloaded copy constructor could be slashed radically. This leads to huge performance gains, especially when dealing with huge vectors of MeteoData (which are needed for filtering, resampling, etc).

Furthermore the access to the meteo parameters has been simpleified by overloading the operator(), replacing the old .param(size_t index) and .param(string paramname) functions:

MeteoData md;
double ta = md(MeteoData::TA);

OR

double ta = md("TA");

These changes were propagated into all of MeteoIO.

The full support for timezones has been brought back. This fixes issue 71. The SMET, SMET, IMIS, BORMA plugins have been validated. Geotop should be validtaed if an input data set is available. A new class will have to be implemented to represent time periods. This is currently only a typedef pointing to the Date class, but a specific class would be welcomed.

GSN has been fixed for some changes on the web service, but does not retrieve the correct timestamps (is this a GSN issue?). The GSN compilation has been improved: the warnings related to GSOAP have been removed. 

A new long wave radiaiton model using cloudiness as input has been added (Omstedt, 1990). 

Further improvements to the new filtering infrastructure: windowed filters now inherit from the class WindowedFilter, giving them an easy handle on getting the correct window for every data point. FilterMedianAvg and FilterMeanAvg now fully implemented (soft/not soft, left/center/right windowing). Sample io.ini:

[Filters]
TA::filter1     = mean_avg
TA::arg1        = soft right 5 3600
TA::filter2     = min_max
TA::arg2        = soft 282 286 280 290

RH::filter1     = median_avg
RH::arg1        = center 8 3600

New filter system rolled out with currently two filters up and running: min_max and mean_avg (without the soft option, only left or right centering). The new filter system is built upon processing blocks that take a vector<MeteoData> as input and return a processed vector<MeteoData>. The individual filters are stacked in a ProcessingStack where they are invoked sequentially.

MeteoData now has an extra public member variable: StationData meta. It will hold the meta information of the measurment instead of dragging along a second vector<StationData> alongside the vector<MeteoData> everywhere.

This has huge implications: the IOInterface has been rewritten, subsequently changes need to be propagated into all plugins and all modules dealing with meta data.

The new filtering and resampling framework. Filtering/Processing and Resampling have been separated from each other, the Resampling is now done with the class Meteo1DInterpolator which utilizes the static algorithms within ResamplingAlgorithms. The filtering remains a task of class MeteoFilter. The calling of the resampling and filtering as well as the data selection is now based in the facade class MeteoProcessor. MeteoProcessor::processData function calls the filtering algorithms, then passes the filtered data to the resampling algorithms and finally runs a "check only" filtering pass.

The filtering system underwent some changes in order to simplify the tasks at hand, the interface has changed.

The RateFilter is currently disfunctional, needs to be reimplemented.

Overall all include statements within in the library have been replaced by angle brackets, the default install path for the include file is $CMAKE_INSTALL_DIR/include/meteoio, the meteoio libraries (static and shared) will be installed in $CMAKE_INSTALL_DIR/lib per default.

The plugins will be installed in the subdirectory $CMAKE_INSTALL_DIR/lib/meteoio/plugins

Changed the name of the Date_IO class to Date. In case of namespace conflicts, just use mio::Date to reference the MeteoIO Date class.

The license information has been added: LPGLv3 headers in all header files, license texts as well as a Linux Software Map entry file.

The installation procedure has been added to cmake configuration files (similar to the autotools)

MeteoFilter operates on static filter algorithms which are defined in FilterAlgorithms.*
FilterProperties is a small helper class to declare properties of an Algorithm (e.g. how many data points it requires, ...)
The new MeteoFilter system is utilized by class BufferedIOHandler.

The old filter system is removed from Makefiles/CMake and the SVN directory.
Legacy MeteoIO classes Meteo1DResampler and MeteoBuffer, which were solely required by the old filter system are also removed.
