SpatialX

Library (based on NetworkX) to analyse spatial networks. Please contribute!

Beware!

This code does not have any test suite (yet!). Please consider the results of the algorithms with extreme care, or better, help us by writing tests!

Dependencies

• NetworkX
• Fiona (for shapefile imports)
• Numpy

Use

import spatialx as sx

Features

I/O

• Import Line shapefiles into a spatial network [tested]
• Export spatial network to Shapefile [tested] It is easier to visualise large networks in GIS softwares.

Statistics of paths

Paths

Centralities

• Betweenness centrality

  • Usual betweenness centrality (nodes and edges)
  • Generalized betweenness centrality (nodes and edges)

• Random walk centrality (nodes and edges)

• Greedy Navigator Centrality (nodes and edges)

Faces and dual network

• Extraction of faces

• Extraction of dual networkx

Information representation

• Extraction of lines
  • Intersection Continuation Negotiation algorithm

Other features

• Simplification of spatial networks to speed up calculations
