Computational Component

Since the occupational sequence of this site is particularly complex, with large quantities of finds, particularly pottery and coins, a successful excavation will hinge upon a computerized recording system that integrates site records, laser scan and GPS data, plans, videos, photographs and polynomial texture maps, and finds. This system relates these data to the recording of substantial standing structures. Established methods have been drawn together, complemented by development of an innovative system tailored to the characteristics of Portus. As far as possible records collected in the field are ‘born digital’, enabling rapid and consistent recording.

In addition to conventional context and finds records, all objects will be available as laser scans or as fully scaled interactive 3D images (polynomial texture maps). The system makes available the whole site archive (plans, sections, finds databases and digital assets) to all project members via a project intranet, as well as facilitating data archiving and eventual dissemination via AHDS Archaeology. Standing structures are being recorded volumetrically by high-precision laser scanners, image rectification and conventional building survey techniques.
