ABSTRACT 
This paper is about data acquisition by digital photogrammetry method for the preservation of cultural 
assets. As the result of this study, precise digital 
depth model could be developed on a personnel 
computer. The model can be than kept together with the image data to be used as a recording 
system for the preservation of cultural assets. 
1. Introduction 
There are many cultural assets in Korea, distributed 
countrywide and most of them originated a long. time 
ago, some dating back to more than a thousand years. 
Besides having historic values, the architecture of these 
structures can disclose cultural background of the 
originating time. 
But because of rapid industrialization as well as natural 
hazards such as earthquakes, fires, and floods, most of 
the structures are fragile to damage and. deterioration. 
Digital photogrammetry, referred to as the 4th generation 
phase of photogrammetry, processes digital data rather 
than analog data used in analytical photogrammetry. 
Digital photogrammetry began to be recognized in the 
eighties and active research is still going on in this field. 
The benefits of digital photogrammetry is automation and 
Systematic management of the photogrammetry 
procedures, preservation of data and easy reconstruction 
of photogrammetric conditions. In this study digital 
photogrammetry techniques were applied to acquire basic 
data and to do various analysis and evaluation. 
An experiment was carried out on the main stone statue 
of Buddha which is inside the  Suk-Gul-Am, one of the 
oldest structures in East Asia. Also maps are generated 
of Chum-Sung-Dae the oldest astronomical observatory. 
Analysis of these structures based on acquired data such 
as formative ratio of Suk-Gul-Am is also performed. 
2. Digital Photogrammetry 
Topographic maps are usually made from 
stereophotographs using analytical plotter. Even in the 
case of digital stereoscopic images, which can be get 
from SPOT satellite, analytical plotter is usually used. 
But, in this case, digital images at first must be 
transformed to photographs on film or paper because
