GitHub – pysal/giddy: Geospatial Distribution Dynamics

Gitter room
PyPI version

Giddy is an open-source python library for the evaluation of dynamics of
longitudinal spatial knowledge. Originating from the spatial dynamics module
in PySAL (Python Spatial Evaluation Library), it’s underneath lively growth
for the inclusion of newly proposed analytics that contemplate the
function of area within the evolution of distributions over time.

Beneath are six choropleth maps of US state per-capita incomes from 1929 to 2004 at a fifteen-year interval.



On-line documentation is offered right here.


  • Directional LISA, inference and visualization as rose diagram


Above exhibits the rose diagram (directional LISAs) for US states incomes throughout 1969-2009 conditional on relative incomes in 1969.

  • Spatially specific Markov strategies:
    • Spatial Markov and inference
    • LISA Markov and inference
  • Spatial decomposition of alternate mobility measure (rank strategies):
    • World indicator of mobility affiliation (GIMA) and inference
    • Inter- and intra-regional decomposition of mobility affiliation and inference
    • Native indicator of mobility affiliation (LIMA)
      • Neighbor set LIMA and inference
      • Neighborhood set LIMA and inference
