+- Fix case when __builtins__ is a dict. [Martin Raspaud]
+
+- Update changelog. [Martin Raspaud]
+
+- Bump version: 1.2.2 → 1.2.3. [Martin Raspaud]
+
+- Fix list of package names in setup.py. [davidh-ssec]
+
+ 'pyresample.ewa' wasn't listed before and was not importable from an installed package.
+
+
+- Update changelog. [Martin Raspaud]
+
+- Bump version: 1.2.1 → 1.2.2. [Martin Raspaud]
+
+- Add the header files to the MANIFEST.in. [Martin Raspaud]
+
+ Without this, the compilation of the ewa extension crashes.
+
+- Update changelog. [Martin Raspaud]
+
+- Bump version: 1.2.0 → 1.2.1. [Martin Raspaud]
+
+- Include EWA header files as dependency for extensions. [davidh-ssec]
+
+ The .c and .cpp files are automatically included because they are listed as sources, but the header files are not. When building a source tarball (uploading to PyPI) the _fornav_templates.h file was not included and building would fail.
+
+
+- Merge branch 'pre-master' of github.com:mraspaud/pyresample into pre-
+ master. [Adam.Dybbroe]
+
+- Update changelog. [Martin Raspaud]
+
+- Bump version: 1.1.6 → 1.2.0. [Martin Raspaud]
+
+- Merge branch 'northaholic-feature-lonlat2colrow' into pre-master.
+ [Adam.Dybbroe]
+
+- Add two convenience methods lonlat2colrow and colrow2lonlat to
+ AreaDefinition-class. [Sauli Joro]
+
+- Merge branch 'pre-master' of github.com:mraspaud/pyresample into pre-
+ master. [Adam.Dybbroe]
+
+ Conflicts:
+ docs/source/conf.py
+
+
+- Fix bug in EWA grid origin calculation. [davidh-ssec]
+
+ Forgot that cell height was negative so ended up subtracting a negative, going in the wrong direction for the Y origin of the grid.
+
+
+- Merge pull request #37 from davidh-ssec/feature-ewa-resampling. [David
+ Hoese]
+
+ Feature ewa resampling
+
+- Fix bug in EWA conversion from AreaDefinition to upper-left origin
+ X/Y. [davidh-ssec]
+
+ I was using the area extent for the origin x/y locations, but the extent is actually the outer edge of the pixels so half a pixel needs to be added to each coordinate.
+
+
+- Add EWA C extensions to mocked modules for read the docs. [davidh-
+ ssec]
+
+ Readthedocs.org fails to import the _ll2cr and _fornav extensions because it seems to not compile them properly. Their documentation isn't necessarily needed so I'm hoping that mocking them will let the import work.
+
+
+- Add pyresample.ewa to API documentation list. [davidh-ssec]
+
+- Update EWA wrapper functions to use explicit kwargs. [davidh-ssec]
+
+- Correct comments and documentation in EWA documentation. [davidh-ssec]
+
+- Add ll2cr and fornav wrappers to make calling easier. [davidh-ssec]
+
+ Updated documentation with correct usage and added information why EWA is different than kdtree
+
+
+- Fix print statements in documentation so doctests are python 3
+ compatible. [davidh-ssec]
+
+- Add pillow dependency for plot tests and quicklook extra. [davidh-
+ ssec]
+
+- Add 'areas.cfg' file to repository and modify doctests to use that
+ instead. [davidh-ssec]
+
+- Run doctests after unittests on travis. [davidh-ssec]
+
+- Fix documentation for AreaDefinition object. [davidh-ssec]
+
+- Update documentation to be numpy style and get rid of all warnings
+ when building docs. [davidh-ssec]
+
+- Create special requirements.txt for docs. [davidh-ssec]
+
+ Readthedocs really doesn't like an empty string for the requirements file
+
+
+- Try empty string for requirements file in readthedocs yaml. [davidh-
+ ssec]
+
+- Fix readthedocs yaml config file. [davidh-ssec]
+
+ Readthedocs was using the requirements file during package installation, but was failing to install basemap (not needed for documentation build) so I attempted to make it an empty string in the yaml file. This makes Rtd hang on the build process. This should at least stop the hanging.
+
+
+- Add napoleon docs extension and intial testing with numpy style
+ docstrings. [davidh-ssec]
+
+- Add working example for EWA resampling to docs. [davidh-ssec]
+
+ I originally had this example but removed it when I had import problems. After I figured those out I forgot to put the original example back.
+
+
+- Add basemap back in to the requirements.txt so that it can be
+ installed on travis. [davidh-ssec]
+
+ Similarly removed the requirements file when readthedocs is running and mocked third-party packages to documentation can still be built
+
+
+- Fix setup.py requiring numpy for extension includes. [davidh-ssec]
+
+ The EWA extensions require the numpy headers to be built. These are normally found by importing numpy and doing `numpy.get_includes()`. Obviously if this is run on a new environment numpy is probably not installed so a simple `python setup.py install` will fail.
+
+
+- Add "quicklook" extra in to travis test install. [davidh-ssec]
+
+ These packages are needed to properly test the "plot" package. These were included in requirements.txt but have been moved for now.
+
+
+- Move plot test imports in to test functions for cleaner test failures.
+ [davidh-ssec]
+
+- Add readthedocs yaml file for configuration. [davidh-ssec]
+
+- Remove mocked modules from sphinx docs conf.py. [davidh-ssec]
+
+ This is the first step in making pyresamples docs buildable in the current readthedocs version
+
+
+- Replace relative imports with absolute imports. [davidh-ssec]
+
+ I noticed a lot of warnings and import problems with building pyresample's documentation because of these relative imports
+
+
+- Add EWA documentation to swath.rst. [davidh-ssec]
+
+- Add tests for EWA fornav module. [davidh-ssec]
+
+- Update documentation for ll2cr and fornav cython. [davidh-ssec]
+
+- Merge remote-tracking branch 'davidh_fork/feature-ewa-resampling' into
+ feature-ewa-resampling. [davidh-ssec]
+
+ # Conflicts:
+ # pyresample/ewa/_fornav.pyx
+ # pyresample/ewa/_ll2cr.pyx
+
+
+- Remove old and unused polar2grid ll2cr and fornav python modules.
+ [davidh-ssec]
+
+- Fix travis tests on python 2.6. [davidh-ssec]
+
+- Add ewa ll2cr tests to main test suite. [davidh-ssec]
+
+- Add simple tests for ewa ll2cr. [davidh-ssec]
+
+ These tests were adapted from Polar2Grid so some of the terminology or organization might reflect P2G's design rather than satpy or pyresample.
+
+
+- Revert import multiprocessing setup.py for python 2.6 compatibility.
+ [davidh-ssec]
+
+- Fix old polar2grid import in ll2cr module. [davidh-ssec]
+
+- Add method for converting area def to areas.def string format.
+ [davidh-ssec]
+
+- Remove unused code from fornav wrapper. [davidh-ssec]
+
+- Add initial EWA files copied from Polar2Grid. [davidh-ssec]
+
+- Add basic documentation to fornav cython function. [davidh-ssec]
+

+- Remove unused code from fornav wrapper. [davidh-ssec]
+
+- Add initial EWA files copied from Polar2Grid. [davidh-ssec]
+
+- Add .gitignore with python and C patterns. [davidh-ssec]
+
+- Update tests so they don't fail on OSX. [davidh-ssec]
+
+ OSX seems to calculate slightly different results from `_spatial_mp.Cartesian` regardless of numexpr being installed. Although the changes are small they seem to affect the results enough to fail this test compared to normal linux execution.
+
+
+- Add 'load_tests' for easier test selection. [davidh-ssec]
+
+ PyCharm and possibly other IDEs don't really play well with unittest TestSuites, but work as expected when `load_tests` is used.
+
+
+- Update changelog. [Martin Raspaud]
+
- Bump version: 1.1.5 → 1.1.6. [Martin Raspaud]
+- Run the base class init function first. [Adam.Dybbroe]
+
+- Make kd_tree test work on older numpy version. [Martin Raspaud]
+
+ VisibleDeprecationWarning is not available in numpy <1.9.
+
+- Adapt to newest pykdtree version. [Martin Raspaud]
+
+ The kdtree object's attribute `data_pts` has been renamed to `data`.
+
+- Run tests on python 3.5 in travis also. [Martin Raspaud]
+
- Fix #35 supporting scipy kdtree again. [Martin Raspaud]
A previous commit was looking for a 'data_pts' attribute in the kdtree

+pyresample.ewa
+--------------
+
+Pyresample makes it possible to resample swath data to a uniform grid
+using an Elliptical Weighted Averaging algorithm or EWA for short.
+This algorithm behaves differently than the KDTree based resampling
+algorithms that pyresample provides. The KDTree-based algorithms
+process each output grid pixel by searching for all "nearby" input
+pixels and applying a certain interpolation (nearest neighbor, gaussian, etc).
+The EWA algorithm processes each input pixel mapping it to one or more output
+pixels. Once each input pixel has been analyzed the intermediate results are
+averaged to produce the final gridded result.
+
+The EWA algorithm also has limitations on how the input data is structured
+compared to the generic KDTree algorithms. EWA assumes that data in the array
+is organized geographically; adjacent data in the array is adjacent data
+geographically. The algorithm uses this to configure parameters based on the
+size and location of the swath pixels.
+
+The EWA algorithm consists of two
+steps: ll2cr and fornav. The algorithm was originally part of the
+MODIS Swath to Grid Toolbox (ms2gt) created by the
+NASA National Snow & Ice Data Center (NSIDC). Its default parameters
+work best with MODIS L1B data, but it has been proven to produce high
+quality images from VIIRS and AVHRR data with the right parameters.
+
+.. note::
+
+ This code was originally part of the Polar2Grid project. This
+ documentation and the API documentation for this algorithm may still
+ use references or concepts from Polar2Grid until everything can
+ be updated.
+
+Gridding
+********
+
+The first step is called 'll2cr' which stands for "longitude/latitude to
+column/row". This step maps the pixel location (lon/lat space) into area (grid)
+space. Areas in pyresample are defined by a PROJ.4 projection specification.
+An area is defined by the following parameters:
+
+ - Grid Name
+ - PROJ.4 String (either lat/lon or metered projection space)
+ - Width (number of pixels in the X direction)
+ - Height (number of pixels in the Y direction)
+ - Cell Width (pixel size in the X direction in grid units)
+ - Cell Height (pixel size in the Y direction in grid units)
+ - X Origin (upper-left X coordinate in grid units)
+ - Y Origin (upper-left Y coordinate in grid units)
+
+Resampling
+**********
+
+The second step of EWA remapping is called "fornav", short for
+"forward navigation". This EWA algorithm processes one input scan line
+at a time. The algorithm weights the effect of an input pixel on an output
+pixel based on its location in the scan line and other calculated
+coefficients. It can also handle swaths that are not scan based by specifying
+`rows_per_scan` as the number of rows in the entire swath.
+How the algorithm treats the data can be configured with various
+keyword arguments, see the API documentation for more information.
+Both steps provide additional information to inform the user how much data
+was used in the result. The first returned value of ll2cr tells you how many
+of the input swath pixels overlap the grid. The first returned value of fornav
+tells you how many grid points have valid data values in them.
+
+Example
+*******
+
+.. note::
+
+ EWA resampling in pyresample is still in an alpha stage. As development
+ continues, EWA resampling may be called differently.

+"""Code for resampling using the Elliptical Weighted Averaging (EWA) algorithm.
+
+The logic and original code for this algorithm were translated from the
+software package "MODIS Swath 2 Grid Toolbox" or "ms2gt" created by the
+NASA National Snow & Ice Data Center (NSIDC):
+
+ https://nsidc.org/data/modis/ms2gt/index.html
+
+Since the project has slowed down, Terry Haran has maintained the package
+and made updates available:
+
+ http://cires1.colorado.edu/~tharan/ms2gt/
+
+The ms2gt C executables "ll2cr" and "fornav" were rewritten for the
+Polar2Grid software package created by the Space Science Engineering Center
+(SSEC)/Cooperative Institute for Meteorological Satellite Studies. They were
+rewritten as a combination of C++ and Cython to make them more python friendly
+by David Hoese and were then copied and modified here in pyresample. The
+rewrite of "ll2cr" also included an important switch from using the "mapx"
+library to using the more popular and capable pyproj (PROJ.4) library.
+
+The EWA algorithm consists of two parts "ll2cr" and "fornav" and are described
+below.
+
+ll2cr
+-----
+
+The "ll2cr" process is the first step in the EWA algorithm. It stands for
+"latitude/longitude to column/row". Its main purpose is to convert
+input longitude and latitude coordinates to column and row coordinates
+of the destination grid. These coordinates are then used in the next step
+"fornav".
+
+fornav
+------
+
+The "fornav" or "Forward Navigation" step of the EWA algorithm is where
+the actual Elliptical Weighted Averaging algorithm is run. The algorithm
+maps input swath pixels to output grid pixels by averaging multiple input
+pixels based on an elliptical region and other coefficients, some of which
+are determined at run time.
+
+For more information on these steps see the documentation for the
+corresponding modules.
