3.2 Metadata schema for our service
We analyzed the above international and domestic
standard for metadata to design metadata of our satellite
imagery information service. From these results, our metadata
schema are based on the ISO 19115(international metadata
standard for geographic information) and ISO 19115 part
2(extension of ISO 19115 for grid metadata) and we try to
improve the domestic standard (Metadata Standard for
Geographic Information Distribution (TTAS.KO-10.0139)) for
applying the satellite imagery information. Figure 4 shows the
metadata schema for our satellite imagery information
4. FUNCTIONS OF SERVICE
For the registration and management of data, we made the
DRS (Data Registration Software), DMS (Data Management
Software) and DTS (Data Transfer Software). The role of DRS
is making the browser images and thumbnail images to view the
brief image of large satellite images and extract the metadata
from the diverse satellite images. The role of DMS is managing
the raw data in hierarchical process. The role of DTS is
distributing the raw data to users. Figure 6 shows our model of
System for DRS, DMS and DTS.
4.1 Data Registration System
For registering the satellite imagery information, we have
the following two strategies. We made the metadata of satellite
imagery information from raw data if we have raw data. If we
have no raw data, we will make the metadata information about
the place of the raw data. For these purposes, the import things
to consider is extract the common metadata for diverse satellite
images. We design the DRS for the satellite images such as
LANDSAT 2 ~ LANDSAT 7, CORONA, SPOT, JERS,
KOMPSAT-1, IKONOS. For the core metadata of ISO 19115,
we design the DRS to acquire the metadata almost automatically.
Figure 6 shows the picture of DRS.
