What is Digital Heritage Preservation?
The first step is to capture a detailed and multi-faceted snapshot of the site. 3D laser scanning and photography is used to collect highly detailed spatial and visual information. The spatial and visual information can be merged or used separately. Location information can be collected using a GPS, control survey points can be recorded, remote sensing data can be obtained, and a Geographic Information System can be created to hold and analyze new or existing data. All of this can be further enhanced with historic information in the form of written accounts, photographs, maps, and oral history.
Next, collected information is processed and analyzed. Further information can be revealed as digital analysis tools provide a new look at information that was once hidden or scattered. Components that tell the story of a historic site are built and merged. Together these components form the basis for many deliverables that can serve conservation and disemination purposes. As-built drawings, measurable imagery, and standardized heritage documents can be produced for site managment. Public facing tools provide site interpretation or publicity through compelling web-based virtual tours.
