• Pagus is a software tool for assessing the visual impact of a

transport infrastructure (roads, highways, railways, ...).

• Pagus integrates geographic (GIS-based) and visual (images)

information.

• Integrating cutting edge open technologies, Pagus is modular,

agile and user friendly.

• Pagus visual analysis connects with visual characteristics which

are easy to evaluate by non-expert users.

• The future of this pioneering project depends on consolidating

its implantation in consulting companies, integrating it in the

current analysis methodology and assessment and extending

its use in a regional, national and international framework.

its use in a regional, national and international framework.

• Likewise, the tool needs new funding resources to allow a

second phase where many analysis tasks can be automated

using computer vision and artificial intelligence, this way

improving its performance and facilitating even more the

assessment process.
