This chapter introduces an integrated method drawing on all the techniques mentioned to address questions both of archaeological modelling practice and the analysis of their outputs. It explores the Basilica Portuense at the site of Portus, Italy. The chapter develops the Texture Viewsheds method outlines by Eleftheria Paliou and identifies the benefits of comparing such visibility products with lighting analysis and more subjective appraisals of modelled space. It outlines a range of uncertainties in terms of morphology, material, and illumination. The chapter employs the raster-based methodology already outlined only as a means to produce targeted fine-grained coverage's. Paliou considers the potential of approaches such as isovists and VGA that summarize but are not based on true 3-dimensional representations of space. The archaeological remains of the port are situated northwest of the Republican river port of Ostia on the Tyrrhenian sea and about 25 km from Rome.
