Environment Agency lidar data is now freely available for non-commercial use, so I have been setting about making use of it (after jumping through a few hoops to establish my non-commercial credentials in this instance). Roman town sites are the order of the day, particularly green-field sites, as in this instance at Chesterton/Water Newton (Durobrivae). The site of the town and its defences are very evident in the survey, with the route of Ermine Street through the town to the river crossing and beyond especially clear. Dropping the cropmark plot over the top goes to show how much lidar survey can aid understanding of landscape setting (quite apart from its mapping of earthwork features). The site of the palatial complex at Castor lies towards the northern edge of the map (to be added later).
