Travel the Roman roads, Google-style

The Roman road network, renowned for its scope and efficiency, has now gotten even easier to travel thanks to an online application from Stanford University.  ORBIS is a geospatial network model that covers hundreds of land and sea routes in the Roman Empire circa 200 CE.

Users can get the fastest or cheapest route between destinations. They can choose travel options such as river boat, pack mule, or military march. Users can even specify the time of year.

Additional features include distance cartograms between cities, and a map gallery with further trip analysis.
