wradlib.zonalstats.DataSource¶

class wradlib.zonalstats.DataSource(data=None, srs=None, name='layer', source=0, **kwargs)¶

DataSource class for handling ogr/gdal vector data

DataSource handles creates in-memory (vector) ogr DataSource object with one layer for point or polygon geometries.

Parameters

data (sequence of source points (shape Nx2) or polygons (shape NxMx2) or) – ESRI Shapefile filename containing source points/polygons
srs (object) – ogr.SpatialReferenceSystem SRS describing projection of given data

Warning

Writing shapefiles with the wrong locale settings can have impact on the type of the decimal. If problem arise use LC_NUMERIC=C in your environment.

Examples

`dump_raster`(filename[, driver, attr, …])	Output layer to GDAL Rasterfile
`dump_vector`(filename[, driver, remove])	Output layer to OGR Vector File
`get_attributes`(attrs[, filt])	Read attributes
`get_attrs_and_props`([attrs, props, filt])	Read properties and attributes
`get_data_by_att`([attr, value])	Returns DataSource geometries filtered by given attribute/value
`get_data_by_geom`([geom])	Returns DataSource geometries filtered by given OGR geometry
`get_data_by_idx`(idx)	Returns DataSource geometries as numpy ndarrays from given index
`get_geom_properties`(props[, filt])	Read properties
`load_vector`(filename[, source, driver])	Read Layer from OGR Vector File
`set_attribute`(name, values)	Add/Set given Attribute with given values

`data`	Returns DataSource geometries as numpy ndarrays
`ds`	Returns DataSource
