Calculate Roman Centuriation

Background

Centuriation was a surveying method used by the Romans during the late Repulican and early empire to divide land into parcels. This module calculates the heredia (land allotments) and roads of centuriation given a central survey point or groma.

For a more in depth overview of centuriation wikipedia has a good explanation

Installation

npm install limitatio

in Node

const limitatio = require('limitatio');

const groma = {
            "type": "Feature",
            "properties": {},
            "geometry": {
                "type": "Point",
                "coordinates": [
                    13.592042,
                    45.227991
                ]
            }
        };

let limitatio = limitatio(groma, 9);
/* limitatio now holds the GeoJSON for the heredia and roads
