Added a prototype for plotting grids over a basemap (class Grid2Basemap). This
still needs a lot of work to make it robust, but it can already be tested.

Added function polar2latlonalt which returns latitude, longitude and altitude of
radar bin based on elevation, azimuth, range and height of the radar location.

argument sitecoords is a tuple of three, containing lat, lon and height of the
radar location. This function explicitely accounts for the elvation angle as opposed to...

Bug fix in function arguments of correctAttenuationHB (thrs argument missing)

Plus some minor fixes in docstrings...

Introduces Mean Field Bias adjustment approach (class AdjustMFB) to wradlib.adjust

One multiplicative correction factor for the entire radart image.

Minor changes in util to that aggregate_in_time also works with hdf Datasets

Minor change in wradlib.bufr

minor edit in __init__

worked on the Grid2Basemap in wradlib/vis.py

minor change to prevent system console to pop up in case bufr.decodebufr is called.

added variable bufr.bufrproj

Added a function to support the construction of proj.4 projection strings in georef.create_projstr

some little modifications in tutorial_accumulation.rst

added function wradlib.util.from_to to create timelines

just some typos...

The wradlib installation guide has now been modified to the "python setup.py install"
procedure - for users, this should be the standard procedure.

change in io.read_OPERA_hdf5 for converting Dataset to numpy array

OPERA hdf5 file reader, change of the BUFR reader output and lots of DOC

Added a reader for hdf5 files which adhere to the OPERA data model (io.read_OPERA_hdf5)

Changed the output of io.read_BUFR (and bufr.decodbufr) in order to be consistent
with the other reader (one data data object, one metadata object)....

added reader for RADOLAN composite files (io.read_RADOLAN_composite)

enhanced the tutorial about supported data formats

began work on reader for OPERA hdf5 files (io.read_OPERA_hdf5)

DOC: added more documentation to the BUFR module. Added a tutorial about supported
weather radar data formats (not yet complete).

DOC: added documentation to the bufr module and added aan alias to wradlib.bufr.decodebufr
under io.read_BUFR in order to provide a homogeneous appearance under IO.

Introducing BUFR to wradlib

The changeset introduces a wide range of changes which allow the use of BUFR files
in wradib. It introduces a new module named bufr.py which provides a wrapper around
the OPERA BUFR software (version 3.1). The BUFR software library was made part of...

catching LinAlgErrors and returning np.nan as weights

Merge from default

branch : feature/tp/kriging

ExternalDriftKriging is now also saving all estimation variances in self.estimation_variance
However it won't save all weights, because that might use too much space.
