Collaboration with the Pytroll project and the creation of the new SatPy library will result in large internal changes to Polar2Grid.
- SatPy is a replacement for the internals of Polar2Grid and a replacement for the Pytroll mpop package.
- Migrate Polar2Grid frontends to SatPy readers.
- Use SatPy for resampling and output writers, not just some readers.
- Rename frontends to readers, backends to writers, products to datasets.
- The remaining roadmap bullets are subject to change based on the Pytroll/Polar2Grid merger.
- Create new grid file format for more flexibility
- Allow resampling parameters to be configured based on dataset identifiers (satellite, instrument, etc)
- Further fornav updates
- Move all module logic to C++ and remove cython dependency for this module (simple one function cython wrapper should be easy to remove)
- Try rewriting in either opencl or use openmp for multiprocess work, but we're getting to the point that fornav is not the slowest part of fornav (intermediate disk use)
- Consider linking directly to PROJ.4 C library for ll2cr (removing pyproj dependency for ll2cr) to make it faster
- Update rescaling with cython wrapper (test performance before committing to this)
- Needs change of clipping and masking logic so that its a decorator and can be easily excluded from cython code (which would use internal logic for those steps)
- Add proper handling for product data being kept in memory (should speed up quite a few things)
- For better handling of in-memory data, should either let the user choose or determine it based on available memory
- Frontend's could choose logical default (VIIRS should probably write to disk, DR-RTV should stay in memory)
- Glue script can use memory analysis to come up with default but can be forced by command line argument
- Python 3 Compatibility
- Fixed small bug in ll2cr where NaNs in navigation would cause a dynamic grid to never "fit"
- Rewrite of entire internal structure and behavior of polar2grid (Frontends, Backends, Remapping)
- Most frontends (VIIRS, MODIS, etc) are filename independent and try to determine type of file by internal structure
- Frontends now do operations based on what "products" are requested and return a "scene" object
- The polar2grid.core.meta module is added to provide structure to intermediate steps (Frontend -> Remap -> Backend) with the classes it offers
- Backends now operate on a gridded scene as a whole (with option for operating on one product at a time for some backends)
- A compositor role was added to provide a more flexible method of creating true/false color and other composited images
- ll2cr rewritten in python and cython (C-like python) to be faster and more accurate
- Grid determination has been essentially removed since "data fits in grid" decisions don't make sense unless you are in projection/grid space (ll2cr serves this purpose now)
- fornav has been rewritten to be accessed directly from python. The ms2gt version of fornav is no longer used.
- The ms2gt version of fornav was also modified to be faster and is still destributed with the software bundle (for this release only).
- GPD grids and support for them has been removed. PROJ.4 is more flexible, more widely used, and can actually support the AWIPS grids better.
- Python setup.py files updated to better meet common practice of other python projects (READMEs, classifiers, etc)
- Major changes to rescaling so that it can be specified independent of output data type and "increment_by_one"
- Removed AWIPS I support due to National Weather Service using AWIPS II from now on
- Added basic ACSPO and MIRS frontends
- Added HDF5 backend
- Fixed VIIRS CREFL C code and added custom version to repository (viirs_crefl)
- Added ability to use 'deg' units on grid origin definitions
- Latlong grids use degrees instead of radians (affects grid configurations and intermediate values in code)
- Added wgs84_fit_250 grid
- AWIPS grids "fixed" to actually align properly in AWIPS. The grid specification says ellipsoid earth, but my results say spherical.
- Non-TC geolocation used as backup option for VIIRS Frontend
- Fixed major bug when creating true colors (Issue #81). If the high resolution data resolved to a different dynamic grid than the low resolution data then a true color could not be made.
- Fixed frontends handling of symbolic links for files
- Various CREFL fixes
- Added MODIS geotiffs
- Added MODIS 250m bands
- Added MODIS Frontend (limited number of bands)
- Added CREFL Frontend (including true color glue script)
- Changed default geotiff data type to unsigned 8-bit integer
- Added option to provide user created grid configuration files
- NinJo backend added for DWD added
- Object oriented Frontend, Backend, and Rescaling
- Python version of ll2cr (still uses ms2gt fornav)
- Geotiff Backend
- Start of developer's guide in documentation
