HwgdZddlmZddlmZddlmZddlmZddl m Z ddl m Z ddl mZdd lmZmZGd d eZy ) a DataSource is a wrapper for the OGR Data Source object, which provides an interface for reading vector geometry data from many different file formats (including ESRI shapefiles). When instantiating a DataSource object, use the filename of a GDAL-supported data source. For example, a SHP file or a TIGER/Line file from the government. The ds_driver keyword is used internally when a ctypes pointer is passed in directly. Example: ds = DataSource('/home/foo/bar.shp') for layer in ds: for feature in layer: # Getting the geometry for the feature. g = feature.geom # Getting the 'description' field for the feature. desc = feature['description'] # We can also increment through all of the fields # attached to this feature. for field in feature: # Get the name of the field (e.g. 'description') nm = field.name # Get the type (integer) of the field, e.g. 0 => OFTInteger t = field.type # Returns the value the field; OFTIntegers return ints, # OFTReal returns floats, all else returns string. val = field.value )byref)Path)GDALBase)Driver) GDALException)Layer)ds) force_bytes force_strcbeZdZdZej Zd dZdZdZ dZ e dZ e dZ y) DataSourcez Wraps an OGR Data Source object.c2|rd|_nd|_||_tjt |t t frItj} tjt||jt|}nJt ||jrt |tjr|}ntdt|z|r||_t||_ytd|z#t$rtd|zwxYw)Nrz%Could not open the datasource at "%s"z"Invalid data source input type: %szInvalid data source file "%s")_writeencodingrensure_registered isinstancestrrptr_typecapiopen_dsr rrtypeptrdriver)selfds_input ds_driverwriterr s Y/var/www/horilla/myenv/lib/python3.12/site-packages/django/contrib/gis/gdal/datasource.py__init__zDataSource.__init__7s DKDK    " hd ,)I X\\+h"7eIFVW $-- 0Z v6 B DtH~ UV V DH +DK ?( JK K!!
