GeomSource

fio.GeomSource(file, mode='r', overwrite=False, srs=None)

A source object for geospatial vector data.

Essentially an OGR DataSource wrapper.

Parameters

Name Type Description Default
file str Path to a file. required
mode str The I/O mode. Either r for reading or w for writing. 'r'
overwrite bool Whether or not to overwrite an existing dataset. False
srs str A Spatial reference system string in case the dataset has none. None

Examples

Index the GeomSource directly to get features.

# Load a file
gm = GeomSource(< path-to-file >)

# Index it!
feature = gm[1]
