emsarray.operations.geometry#

emsarray.operations.geometry.to_geojson(dataset)#

Make a geojson.FeatureCollection out of the cells in this dataset, one feature per cell.

Each feature will include the linear index and the native index of the corresponding cell in its properties.

Parameters

dataset (xr.Dataset) – The dataset to export as GeoJSON geometry.

Returns

geojson.FeatureCollection – The geometry of this dataset as a FeatureCollection.

write_geojson()

emsarray.operations.geometry.write_geojson(dataset, path)#

Export the geometry of this dataset to a GeoJSON file as a geojson.FeatureCollection with one feature per cell.

Each feature will include the linear index and the native index of the corresponding cell in its properties.

Parameters

  • dataset (xr.Dataset) – The dataset to export as GeoJSON geometry.

  • path (str or pathlib.Path) – The path where the geometry should be written to.

emsarray.operations.geometry.write_shapefile(dataset, target=None, *, shp=None, shx=None, dbf=None, prj=None, **kwargs)#

Write the geometry of this dataset to a Shapefile. Each polygon is saved as an individual record with name, linear_index, and index fields.

Parameters

  • dataset (xarray.Dataset) – The dataset to export the geometry for.

  • target (str or pathlib.Path, optional) – Where to save the shapefile. The names for the .shp, .shx, .dbf, and .prj files are derived from this. Optional, you can instead provide arguments for each individual file.

  • shp, shx, dbf, prj (str or pathlib.Path or opened file handle) – Where to write the individual shapefile components to. Optional, you can instead provide the base path as target.

  • **kwargs – An extra keyword arguments are passed on to the shapefile.Writer instance.
