wradlib.io.gdal.VectorSource

class wradlib.io.gdal.VectorSource(data=None, trg_crs=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 or str) – sequence of source points (shape Nx2) or polygons (shape NxMx2) or Vector File (GDAL/OGR) filename containing source points/polygons

• trg_crs – Coordinate Reference System (CRS) of the coordinates. Can be one of:

  • A pyproj.crs.CoordinateSystem instance

  • A cartopy.crs.CRS instance

  • A osgeo.osr.SpatialReference instance

  • A type accepted by pyproj.crs.CRS.from_user_input (e.g., EPSG code, PROJ string, dictionary, WKT, or any object with a to_wkt() method)

  CRS the source data should be projected to.

Keyword Arguments:

• name (str) – Layer Name, defaults to “layer”.

• source (int) – Number of layer to load, if multiple layers in source shape file.

• mode (str) – Return type of class access functions/properties. Can be either of “numpy”, “geo” and “ogr”, defaults to “numpy”.

• src_crs –

  Coordinate Reference System (CRS) of the coordinates. Can be one of:

  • A pyproj.crs.CoordinateSystem instance

  • A cartopy.crs.CRS instance

  • A osgeo.osr.SpatialReference instance

  • A type accepted by pyproj.crs.CRS.from_user_input (e.g., EPSG code, PROJ string, dictionary, WKT, or any object with a to_wkt() method)

  CRS in which source data is provided in.

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.
