본 논문에서는 위성원격탐사의 제도적 정비와 향후 입법 과정에서의 사전 참고로서 이와 관련한 법적 문제들을 검토해 보았다. 위성원격탐사와 관련해서는 광범위한 법적 논점들이 제기될 수 있으나, 본 논문에서는 위성원격탐사에 관한 운용규제와 위성데이터의 거래규제 문제들에 논의의 중심을 두고, 우리법상의 본격적인 입법론적 방안을 위한 선행 연구로서, 비교법적 검토를 시도하였다. 먼저 위성원격탐사와 관련한 국제우주법 체제를 우주조약 체제와 UN원격탐사원칙으로 구분하여 개관하였고, 위성원격탐사에 관한 주요국의 입법례를 살펴보았다. 입법 연혁에 따라 미국, 캐나다, 독일, 프랑스, 일본의 순서로 각 법규들의 성립 배경과 구체적인 입법적 구조 및 주요 내용 등을 구체적으로 분석해 보았다. 이후, 비교법적 검토를 토대로, 위성원격탐사 법제 정비와 관련한 몇 가지 논점들을 상정하여, 시사점 내지 개별적인 의견 등을 제시하였다. 2020년 현재까지 '국내 입법'으로 위성원격탐사에 관한 법제 정비를 시도한 국가들로는 미국, 캐나다, 독일, 프랑스, 일본이 유일하다. 이들 국가들은 자체적인 위성 운용시스템과 위성데이터보호에 관한 입법적 체계를 마련하여, 위성원격탐사에 관한 법률적 규율을 실시하고 있다. 우리나라도 2010년부터 '천리안 위성'을 운용하며 해양·기상 관측을 행하고 있는 위성원격탐사 수행국이라 할 수 있는데, 아직 그와 관련한 법제는 몇 가지의 정부 훈령을 제외하고는 마련되지 않은 상황이다. 그러나 위성데이터의 활용 플랫폼이 큰 폭으로 변화하고 있고, 소형 관측위성의 개발도 고려할 수 있는 지금, 데이터에 대한 접근성과 활용도는 향후 큰 폭으로 상승할 것이다. 이러한 점들을 고려할 때, 우리나라에서도 관측위성시스템과 위성데이터를 종합적으로 관리할 수 있는 입법 추진이 필요할 것으로 보인다. 특히 국가안보와 정보보안의 측면에서도 위성데이터에 대한 일정한 보급규제가 제도적으로 필요할 것이다.

A satellite remote sensing is useful for vegetation monitoring. But it has some problem. One of these, it is difficult to find a difference of vegetation surface roughness using satellite remote sensing. Each vegetation type has unique surface roughness, for example needle leaves forest, broad leaves forest and grassland. Difference of vegetation surface roughness can be detected by satellite multiangular observation. In this study, objective is to propose index of vegetation surface roughness using BRF property. General vegetation indices are calculated from nadir data of satellite data. A proposed index is calculated from two different observation zenith angle data. Two different zenith data can provide BRF (Bi-directional Reflectance Factor) property of satellite observation data. A proposed index was able to detect different value on where NDVI shows similar high value areas of rice field and forest. This index is useful for vegetation monitoring.

Satellite IKONOS images are one of important remote sensing data sources as today because of their very high spatial resolution. Their detections for islands and offshore oceanic features with multi-dimension and multi-scales information, specially some small islands, are of great potential. Their application abilities in islands and offshore detections are addressed at the first of the paper. And image processing technologies and the information extracting methodologies are described. Some results on remote sensing of the islands and their nearby object features are shown in details. Discussions and conclusions are carried out simply at the final.

Remote sensing has been widely used in the exploration of groundwater. In this paper, on the establishment of empirical function between ground water and soil moisture content 6S code is used to reduce uncertainties in the remote sensing of groundwater. Then ground water levels are calculated using 6S corrected and uncorrected ETM+ image along with isochronous meteorological information. Greater correspondence between field examined and satellite monitoring data is obtained from corrected image than from the uncorrected image.

RAZAKSAT is a second micro-satellite mission by Malaysian Satellite Program and is expected for launch in June 2004. Designed to orbit the earth at low-equatorial orbit, RAZAKSAT will meet Malaysia’s immediate needs to rapid data acquisition (real time and more repetitions) to address many operational issues of remote sensing applications, which require availability of current data sets. RAZAKSAT will be among the first remote sensing satellite to orbit the earth at low inclination along the equator, 9$^{\circ}$ with 685km altitude, hence, allows optimal geographical information and environment change within equatorial region be observed with a unique revisit characteristics. The satellite primary payload is MAC, a push-broom type camera with 2.5m of ground sampling distance (GSD) in panchromatic band and 5m of GSD in four multi-spectral bands. This paper describes on the variation of illumination anticipated from simulated RAZAKSAT image, examine its implication to its ground leaving radiances for major applications.

The aim of this study is to evaluate the hazard of landslides at Penang, Malaysia, using a Geographic Information System (GIS) and remote sensing. Landslide locations were identified in the study area from interpretation of aerial photographs and field surveys. The topographic and geologic data and satellite image were collected, processed and constructed into a spatial database using GIS and image processing. The used factors that influence landslide occurrence are topographic slope, topographic aspect topographic curv ature and distance from drainage from topographic database, geology and distance from lineament from the geologic database, land use from TM satellite image and vegetation index value from SPOT satellite image. Landslide hazardous area were analysed and mapped using the landslide-occurrence factors by probability - likelihood ratio - method. The results of the analysis were verified using the landslide location data. The validation results showed satisfactory agreement between the hazard map and the existing data on landslide location.

In this paper, we describe the configuration of the KITSAT-3 image data receiving, archiving, processing and distribution system in operation. Following the low-cost and software-based design concept, the whole system is composed of three PCs : two for data receiving, archiving and processing which provide a full dual-redundant configuration and one for image catalog browsing which can be accessed by public users. Except that receiving and archiving PCs have serial data ingest boards plugged in, they are configured by general peripherals. This basic and simple hardware configuration made it possible to show that a very low cost system can support a full ground operation for the utilization of high-resolution satellite image data.

A virtual vessel traffic control system is introduced to contribute to prevent a marine accident such as collision and stranding from happening. Existing VTS has its limit. The virtual vessel traffic control system consists of both data acquisition by satellite remote sensing and a simulation of traffic environment stress based on the satellite data, remotely sensed data And it could be used to provide timely and detailed information about the marine safety, including the location, speed and direction of ships, and help us operate vessels safely and efficiently. If environmental stress values are simulated for the ship information derived from satellite data, proper actions can be taken to prevent accidents. Since optical sensor has a high spatial resolution, JERS satellite data are used to track ships and extract their information. We present an algorithm of automatic identification of ship size and velocity. It lastly is shown that based on ship information extracted from JERS data, a qualitative evaluation method of environmental stress is introduced.

Recently, the improvement of on-board satellite sensors covering hyperspectral image sensors, high spatial resolution sensors provide data on earth in diverse aspect. The application field relating remotely sensed data also varies depending on what type of job one wants. The various resolution of sensors from low to extremely high is also available on the market with a user defined specific location. The expense to purchase remote sensed data is going down compare to the cost it need past few years ago in terms of research or private use. Now, the satellite remote sensed data is used on the field of forecasting, forestry, agriculture, urban reconstruction, geology, or other research field in order to extract meaningful information by applying special techniques of image processing. There are many image processing packages available worldwide and one common aspect is that they are expensive. There need to be a advanced satellite data processing package for people who can not afford commercial packages to apply special remote sensing techniques on their data and produce valued-added product. The study was carried out with the purpose of developing a special satellite data processing package which covers almost every satellite produced data with normal image processing functions and also special functions needed on specific research field with friendly graphical user interface (GUI). And for the people with any background of remote sensing with windows platform.
