ABSTRACT:
The high prices and lack of information for satellite images prevent researchers from studying remote sensing and most non-
professional people doesn't have the simple and easy solutions for the manipulation of satellite images. “Satellite Imagery
Information Management" system which is promoted by ETRI (Electronics and Telecommunications Research Institute) in Korea
will provide the solutions for the above mentioned problems. Our system manages the satellite imagery information and provides the
simple and easy software for the manipulation of satellite imagery information. We means the satellite imagery information as
satellite images (Landsat, SPOT, JERS, Corona etc) and products(DEM, GCP, land cover map etc) using satellite images and other
primitive sources in remote sensing. "Satellite Imagery Information Management" system consists of hardware and software system.
Our hardware system consists of servers (web services and data processing), RAID (online data management) and Jukebox (nearline
and offline data management). Software consists of four components: DRS (Data Registration Software), DMS (Data Management
Software), DTS (Data Transfer Software), WS (Web Service). For the efficient service, we make the relation between four
components and design the corresponding software. DRS has the following functions: analysis of head for satellite images and
management data for products, generation of browser images and thumbnail images for raster data. DMS has the following
functions: editing for metadata of satellite imagery information, control of RAID and Jukebox, backup for database and system. DTS
has the following functions: online and offline transfer and media control. WS has the following functions: online color composition
for Landsat images, online image treatment (zoom in and zoom out, image enhancement etc), order management etc. For the user's
service, we will suggest the customized software service (e.g., geotiff image converter of Landsat image for each band) which users
want to have for each work. This model of system for "Satellite Imagery Information Management" can be applied to the systems
which handle large amount of data without converting the original data and promote the study of remote sensing about satellite
images.

Since satellite image has properties of high resolution and Telecommunication Research Institute) in Korea will provide
multispectral, it is originally used in the military and ^ the solutions for the above mentioned problems. For the data
environmental field. But it is used more and more in the field of construction, we will show the processing of standard for
map production, agriculture, forestry, planning of national land, satellite imagery metadata in international domain and domestic
establishment of city plan, etc lately. Possibility of periodic data domain. For the data management, we will introduce the
acquisition of satellite image and diverse satellite images hardware system for online, nearline and offline management
between hyperspectral and high resolution satellite image system of data. Finally, you will experience the web service and
makes the satellite images the important resource for the record off line service for data distribution.
of national land. So, it is necessary to preserve the satellite
images which contain the change of geographic information,
national land, and environment for the form of digital library or
museum.
2. TRENDS OF INTEGRATED MANAGEMENT OF
SATELLITE IMAGERY INFORMATION
Though many government organizations, self-governing
body and public research institution make use of satellite image
and do its own project under the base of satellite image now in
Korea, insufficient cooperation and co-work result in the
overlapping purchases of satellite image widely. In addition,
processing of satellite image is done using foreign software
because of non-systematic management of the developed
technology and these facts result in the mass budget waste for
each year. For the solution of these problems, it is necessary to
establish the service which gives and manages the information
of satellite image systematically and distribute information to
the institute which need freely.
USGS (U.S. Geological Survey) has three Clearing houses
for the distribution of data: EROS (Earth Resources
Observation Systems) Data Center Clearinghouse Gateway,
Alaska Geospatial Data Clearinghouse Gateway, and GLIS
(Global Land Information System) Clearing Gateway. FGDS
(Federal Geographic Data Committee) provides the metadata
and distribution standard for the USGS.
