About the Project

The aim of this project is to spatially reconstruct an exceptional architectural source from early modern Portugal called the “Livro das Fortalezas” (Book of Fortresses). This bound volume was created by a Portuguese squire named Duarte de Armas in 1509-1510. It includes a set of perspective drawings from two vantage-points of over 50 castles on the border between the kingdoms of Portugal and Spain and a second set of measured plans for each site.

Student researchers began working on the following aspects of the project in Fall 2017:

• 3D reconstructions of the castles according to Duarte de Armas’ perspective drawings and measured plans
• Categorization and tagging of architectural features and images of daily life in each of the 160+ drawings into a cloud-based spatial database
• GIS analysis from data marking the location of each fortress (ex: viewshed analysis and least-cost-path analysis.)
• Combining digitized images of the drawings and plans with GIS layers in a 3D GIS scene in ArcGIS Pro.
• Research into procedural modeling techniques to help place 3d buildings of walled towns surrounding the castles.
