5. CONCLUSIONS
In this research, ortho imagery was efficiently generated from
SPOT5 single image and an existing digital map. And analysis
of positional accuracy of ortho imagery which was generated
from SPOT5 single image was performed by comparing with
reference digital map produced by National Geographic
Information Institute of Korea. It would be presented for ortho
imagery mapping and applications using SPOT5 single image.
The accuracy results of ortho imagery which was generated
from SPOT5 single image were calculated respectively
±5.666m in X and ±6.284m in Y. And these results are within
the permissible accuracy required for the map revision on a
scale of 1 to 25,000 on the mapping rule notified by the
National Geographic Information Institute of Korea. It is proved
that ortho imagery using a single satellite image is effectively
used to applications considering economical efficiency and
reality. The present topic of mapping and map revision using
ortho imagery by a single satellite image is a limit to scale, but
if it use satellite imagery with higher spatial resolution, it will
be useful to mapping applications of a large scale.
