An IOUtils function has been created to handle cleaning path strings. This is used by the jnative Java binding. The Geotop plugin has been removed from the jnative Java binding, because the binding loads grids but no meteo data and Geotop does not contain grids...

The latest version of jnative now correctly compiles. A trivial bug was preventing it... Paths have been updated (for includes), configuration keys now use the latest syntax (even if the keys are never used afterwards...) and the Makefiles now produces a working library for Linux.

1) The precipitation for IMIS stations is given in mm/h (a rate), but given to us in half hour steps, the cumulative value therefore is the rate divided by 2.
2) The Anetz precipitation interpolation is tricky: vecMeteo is split up into slices of 6 hours and the accumulated anetz precipitation is dispersed over that interval.

Usage in section [Filters]:
HS::filter1 = wma_smoothing
HS::arg1 = soft left 20 3600

Removed timezone support from ImisIO, it leads to horrendous complications in the resampling, which need to be addressed before dealing with timezones.

Bug in IMISIO: the snow height (hs) comes in centimeters out of the database and must be converted into meters.

Small bugfix for BufferedIOHandler, in some cases the rebuffering did not occur, even though buffer was at its end.

The resampling algorithm Accumulate had some errors when dealing with undersampled values. These should be fixed now.

ImisIO: Added the USEANETZ functionality. Many IMIS stations don't have an own precipitation measurement, but there has been some work done to associate the measurements from nearby ANETZ stations with the IMIS stations, thus allowing to calculate a regression for the precipitation for the IMIS stations. If you want to use this feature, then add the following key to your io.ini

[INPUT]
USEANETZ = 1

Small fixes: the MAGNUSS interpolation has been renammed in HNW_SNOW (since we will add avalanche snow redistribution in the future and potentially other things) and the documentation has been reworked.

A severe bug has been found in the spatial interpolations: the algorithm arguments were always the ones from the last evaluated algorithm (therefore not necessarily matching the chosen algorithm).

The MAGNUSS spatial interpolation algorithm now takes as an optional argument the name of the algorithm to use to initialize the grid. 

It is now possible to specify a lapse rate to be used for the CST_LAPSE algorithm (optional argument). If the "soft" argument is added, then a lapse rate is calculated from the data, and if it fails the user provided lapse rate is used instead. Without "soft", only the user provided lapse rate is used. Without any option, only the lapse rate calculated from the data itself is used.

This is the first implementation of the precipitation distribution algorithm discribed in (Magnusson, 2010). This basically initializes the precipitation with an IDW_LAPSE, then removes some or all precipitation according to the local slope, applies a factor depending on the curvature (Huss, 2008) and applies a factor so that the mean precipitation matches the original mean (this is definitely sub-optimal for this part).

Small adjustments to accumulate resampling filter: return IOUtils::nodata in all cases where accumulation is not possible

Fixed a compiler warning in Matrix ("warning: type qualifiers ignored on function return type" , cf http://stackoverflow.com/questions/1607188/why-is-type-qualifier-on-return-type-is-meaningless for full explanations). Small hack/bug fix in SMETIO 8related to issue 87)

The matrix class now uses the standard matrix notation: A(i,j) represents the element j of line i, with index starting at 1 and going to nrows/ncols. The documentation is not yet available...

The matrix class is now independent of Array2D (this makes more sense since arrays and matrices are quite different)

More improvements into the matrix class: the +,-,*,/ operators for doubles have been defined. The +,-,*,==,!= operators also exist for matrix as well as a isIdentity() for checking if a matrix is an identity matrix.

The embryo of a matrix class has been implemented. It is still based on Array2D and therefore the indexing is still 0 to n-1 instead of being 1 to n and the coordinates are swapped compared to normal matrices.

New regression models have been added, all based on the linear regression code but using variable transforms to achieve their goal. 

The global header file (MeteoIO.h) was incomplete. It has therefore been reorganized and now contains everything that it should...

This is the initial commit of the horizon functionnality for DEMs as coded by Fabienne Lanini. Some cleanup will still be required though...

The comparison operator of Coords has been reviewed and improved. The << operator that is not available for a parclass (for popc) can be replaced with IOHandler.toString() for POPC

The DEM object now calculates slope and azimuth in degrees. This is more consistent with the usage of bearings in degrees and of trigonometric angles in radiants.

A missing file has been added to the autotools compilation. A better comparison is performed for Coords objects.

Temporary fix for the << operator and POPC: a par class can not have a "friend" method... (so IOHandler can not redefine "<<" the way we used to do). Therefore, it has been disabled for popc

In order to solve compilation problems with VC++, we need to rename all publicly accessible variables whose name start with a "_". This is the begining of this effort...

More debugging help: the "<<" operator has been redefined for MeteoFilter, MeteoProcessor and BufferedIOHandler. Since the Config object is copied all over the place, it is not always printed.

Several 1D statistical methods has been implemented while the existing ones have been made nodata safe.

Added a redefinition of the << operator for IOPlugin and IOHandler. This should be convenient for debugging!

Some small optimizations have been brought into the spatial interpolations following some tests with cachegrind. Nothing huge, but small improvements.

Added a void write(const string& filename) procedure to the Config class. The Config object can thus be written into an ini file.

Added two functions to MeteoData: bool param_exists(string) and void reset()
reset() sets all the values of the MeteoData object to IOUtils::nodata (note: not the date), and param_exists(string) returns true if a certain parameter exists and false otherwise in a MeteoData object.

The Meteo1DInterpolator now correctly creates MeteoData objects that have more parameters than the default ones (like ta, hnw, ...)
