new GeoDataset
This new implementation of the GeoDataset allows for any geometry type (not only points) to be combined with multi-dimensional data. My suggestion is to develop it next the current implementation which we will remove in a future release.
TODO:
- [x] parse GeoDataFrames to GeoDataset
- [x] GeoDataset to netcdf with conversion of geometry to wkb
- [ ] parse netcdf with wkb to GeoDataset
- [ ] write unit tests
- [ ] decide on data accessor name (geo instead of vector ?)
Related issue: #177
Detailed implementation note:
Right now the geometries are saved in the geometry object of the GeoDataset as a geopandas.array.GeoArray which is a numpy duck array type with additional geometry methods. This does not yet implement the __array__function__ method and can therefore not yet be integrated into a coordinate or variable of a xarray Dataset. Instead in an xarray Dataset it is reduced to a normal numpy objects array.
@hboisgon Could you already have a look a the implementation and let me know what you agree with the approach?
I did write a unit test for an ogr compliant dataset.
Maybe now or in the near future, rename the registration from 'geo' to 'vector'
