hydromt.io.open_vector_from_table(fn, driver=None, x_dim=None, y_dim=None, crs=None, **kwargs)[source]#

Read point geometry files from csv, xy or excel table files.

Parameters:

  • driver ({'csv', 'xls', 'xlsx', 'xy'}) – If ‘csv’ use pandas.read_csv() to read the data; If ‘xls’ or ‘xlsx’ use pandas.read_excel() with engine=openpyxl If ‘xy’ use pandas.read_csv() with index_col=False, header=None, delim_whitespace=True.

  • x_dim (str) – Name of x, y column. By default the x-column header should be one of [‘x’, ‘longitude’, ‘lon’, ‘long’], and y-column header one of [‘y’, ‘latitude’, ‘lat’]. For xy files, which don’t have a header, the first column is interpreted as x and the second as y column.

  • y_dim (str) – Name of x, y column. By default the x-column header should be one of [‘x’, ‘longitude’, ‘lon’, ‘long’], and y-column header one of [‘y’, ‘latitude’, ‘lat’]. For xy files, which don’t have a header, the first column is interpreted as x and the second as y column.

  • crs (int, dict, or str, optional) – Coordinate reference system, accepts EPSG codes (int or str), proj (str or dict) or wkt (str)

Returns:

gdf – Parsed and filtered point geometries

Return type:

geopandas.GeoDataFrame
