ABSTRACT 
This paper presents the recent advances in developing new methodologies to catalogue Brazilian heritage sites in 
colonial stile. The project is a partnership program between the IPF of the University of Karlsruhe (Germany) and the 
LFSG of the Federal University of Santa Catarina (Brazil). Our main goal is to document and model a large amount of 
monuments, using low-cost digital technology introducing colored mosaics. The connection of the 3D geometric and 
alphanumeric database will yield the necessary technical support for the urban planning process, taking into account the 
role of the historical heritage, restoration and preservation of the buildings. 
ZUSAMMENFASSUNG 
Dieser Beitrag prásentiert die Fortschritte in der Entwicklung neuer Methoden zur Dokumentierung von brasilianischen 
Denkmálern im Kolonialstil. Das Projekt ist ein Gemeinschaftsprogramm zwischen dem IPF der Universität Karlsruhe 
(Deutschland) und dem LFSG der Universidade Federal de Santa Catarina (Brasilien). Unser Hauptziel ist eine große 
Anzahl von Monumenten unter Nutzung von digitalen low-cost Technologien zu modellieren und zu dokumentieren. Die 
Verbindung einer 3D-Geometriedatenbank mit alphanumerischen Datenbanken gibt uns die nötige technische 
Unterstützung zur Stadtplanung, um die historischen Denkmäler, zur Restaurierung und Erhaltung der Gebäude, 
miteinzubeziehen.
