ABSTRACT: 
Lately, photogrammetry using aerial digital camera has been utilized widely in the fields of a plan, development and management 
for a national land in advanced countries. There are various benefits using photogrammetry with digital camera imagery, such as the 
prevention of differential stretch errors when scanning analogue films as well as the cost-cutting according to banning the use of 
analogue films. Most of all, one of the biggest benefits is to be able to store, maintain and manage digital imagery in the computers 
without any procedures.In this research, the characteristics which were analyzed on the basis of analysis of properties and 
application cases in digital camera imagery were investigated and a large-scaled map with aerial digital camera imagery was made. 
In order to analyze accuracies of results for the production of digital map using digital camera imagery, the digital topographic maps 
of 1:1000 scale which was produced by Korea National Geographic Information Institute (KNGI) were used. And then the accuracy 
between digital map of KNGI and generated map from digital camera imagery was compared and assessed. From the results of this 
study, it would carry out the accuracy analysis for digital map by digital imagery in a wide area and it would be able to increase the 
uses of the production and application of digital map using digital camera imagery. 
1. INTRODUCTION 
Surveying and mapping are very important techniques for 
development and management of a national land. In order to 
collect geospatial information, various survey techniques are 
required. These techniques from measurements of the moon and 
stars, via a term of using invar tape or a simple instrument to 
GPS surveying or remote sensing have been developing rapidly. 
Aerial photogrammetry started in the mid and late 19th century 
in France. Developing the metric camera in the opening years 
of the 20th century brought the epoch-making turning point to 
mapping wide area, which became the most efficient and 
economical surveying technique to produce topographic map in 
most countries. 
The aerial photogrammetry is used in many spheres. And the 
development of techniques(such as aircraft, computer, etc.) 
changes it from mechanical method and analytical method to 
digital method. 
Nowadays, although techniques and products to relate the aerial 
photogrammetry in Korea is used in many parts of a digital 
environment, aerial photogrammetry using existing analogue 
camera is still conducted, besides the scanning procedure to 
change from analogue imagery to digital imagery has to go 
forward. This procedure of scanning the film wastes expenses 
and time. Furthermore it brings some errors sometimes. 
However, if aerial photogrammetry using digital camera is 
conducted, it needs no more film. So economical efficiency of 
development, operation expense, space, and time can be 
improved, in addition the procedure of scanning to acquire 
digital imagery is enabled to abbreviate and prevent errors of 
scanning procedure. Also, imagery of digital camera is digital 
data, it makes easy to save and manage the data. 
Consequently, this research would be present foundation data 
and reinvigorate relative industry as constructing of geospatial 
information data about research area and analyzing accuracy of 
digital camera imagery. 
2. DIGITAL MAPPING USING AERIAL DIGITAL 
CAMERA IMAGERY 
The process of large-scaled digital mapping using digital 
camera is more effective and economical method than the other 
method using analogue aerial photography, because of omission 
and simplification of scanning, ground control point surveying, 
aerial triangulation. 
In this research, digital mapping has been performed about 
research area using aerial digital camera imagery. Economical 
effectiveness and efficiency of digital mapping was proved by 
executing the accuracy analysis. Figure 1 shows the mapping 
process comparison of analogue versus digital.
