Jittering and routing options for converting origin-destination data into route networks

My talk at FOSS4G 2022:

Origin-destination (OD) datasets provide information on aggregate travel patterns between zones and geographic entities. OD datasets are ‘implicitly geographic’, containing identification codes of the geographic objects from which trips start and end. A common approach to converting OD datasets to geographic entities, for example represented using the simple features standard (Open Geospatial Consortium Inc 2011) and saved in file formats such as GeoPackage and GeoJSON, is to represent each OD record as a straight line between zone centroids. This approach to representing OD datasets on the map has been since at least the 1950s (Boyce and Williams 2015) and is still in use today (e.g. Rae 2009).
