Historic Building Information Modelling (HBIM)

An approach for modelling historic buildings which develops full Building Information Models (BIMs) from remotely sensed data and consists of

1. A library of reusable parametric objects, based on historic architectural data

2. A system for plotting theses library objects onto laser scan survey data

3. Conservation Documentation and Analysis

Data Capture Laser Scanning Digital Photogrammetry
