# 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](https://en.wikipedia.org/wiki/Centuriation) has a good explanation
----
### Installation
```sh
npm install limitatio
```
### in Node
```js
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
```
### in the Browser
```html
```
-----
## Reference
limitatio(groma, bearing)
#### Parameters
* groma - GeoJSON Point Feature - central survey point
* bearing - number - bearing of the survey in degrees from north clockwise
#### Output
* returns a GeoJSON Feature Collection of the *heredia* grid and roads
