raster_tools.Vector

class raster_tools.Vector(geo, size=None)

A class representing vector data.

Take care to provide the actual number of features in the data when creating a new Vector.

__init__(geo, size=None)

Create a Vector object.

Parameters

• geo (GeoDataFrame or GeoSeries) – The vector data to use. This can be a geopandas or dask_geopandas object.

• size (int, optional) – The number of features. If not provided, A best effort will be made to determine the number of features. Part of the data may be temporarily loaded.

Methods

__init__(geo[, size])	Create a Vector object.
add_objectid_column([name])	Add a column of unique ID values to the set of features.
buffer(*args, **kwargs)	Apply the buffer operation to the vector geometries.
calculate_spatial_partitions([show_progress])	Calculate the spatial bounds of the underlying data.
cast_field(name, dtype)	Cast a field to the specified dtype.
copy()	Copies the vector.
eval()	Computes the built-up chain of operations on the underlying data.
load()	Compute delayed operations and load the result into memory.
model_predict(model, fields[, n_outputs, ...])	Predict new columns using a model.
save(path, **fiona_kwargs)	Save the vector data to a file.
simplify(*args, **kwargs)	Simplify the vector geometries.
spatial_shuffle([show_progress])	Shuffle the features into spatially grouped partitions.
to_crs(crs)	Transform the vector coordinates to the specified crs.
to_dask()	Returns the underlying data as a dask_geopandas.GeoDataFrame.
to_dataframe()	Returns the underlying GeoDataFrame.
to_lazy([npartitions])	Converts to a lazy dask-backed Vector.
to_raster(like[, field, ...])	Convert vector feature data to a raster.
to_shapely()	Returns the vector data as a list of shapely geometries objects.
