GeoJSON is another storage format that is human readable. It uses a defined JSON format to store vector data definitions as text. It is easily readable but can get large in size.

Another way to represent vector data, whether in a file or in code, is using the Well-known text (WKT) and Well-known binary (WKB) formats. WKT is human readable, while WKB is not. WKB offers significant ...
