geomob 0.1.0

Geospatial and mobility data library

GeoMob

Welcome to GeoMob, a lightweight library designed to facilitate working with geospatial data. At the moment this library provides essential tools for preprocessing and tessellating geospatial mobility data, making it an excellent choice for developers and researchers in the field of geographic information systems (GIS). I am planning to add many more features. Stay tuned!

Features

Current functionalities

1. Preprocess Module

   • Convert input GeoJSON formats into Shapely Geometries.
   • A lightweight improved version of a stop detection algorithm (2004, Ramaswamy, H., Toyama, K.).
   • A custom made algorithm to detect clean user's trips.
   • A location function to rank users locations during a time window based on different criterions.
   • A function to compress (into an OD table) user's trips.

2. Tessellate Module

   • Module to discretize the space of a shape.
   • Support for many tessellation algorithms (e.g., Squared, S2, GeoHash, H3, Voronoi, etc.)
   • Function to simplify complex polygons into a complex of triangles
   • Efficient function to compute a random set of points in a polygon (useful for synthetic data generation, and for the randomized version of the Voronoi tessellation when points are not provided etc.)

3. Routing Module

   • It supports only iGraph at the moment
   • A simple python isochrone algorithm (not very efficient with large graphs)

4. Retrieve Module

   • A simple function to query OSM for geometries

5. Plot Module

   • At the moment it contains just a function to plot dataframes on KeplerGl

Installation

To install GEOMOB, you can use pip:

pip install geomob
