There are still some key problems having to be solved in theory and technique applications when GPS is used to monitor the vertical deformation of ground with high precision. Utilizing the GPS technology to monitor the deformation of the land subsidence and ground fissure in Xi'an, this paper puts forward advice that the datum frame of GPS network has significant influence on the precision and accuracy of the vertical deformation results by some research. The co-authors make some theoretical study of the datum error and practice by establishing the datum error models, especially the influence of scale and azimuth datum errors on GPS monitoring network. Then the datum frame design methods and arithmetic of GPS monitoring network are presented and have taken a good effect.

본 연구는 도시철도에 의한 도시의 사회 및 공간적 영향을 개통 이후 지속적인 모니터링이 필요하다라는 측면에서 시작되었으며, 이에 본 연구는 대전시의 공간구조에 커다란 영향을 미칠 것으로 예측되고 있는 도시철도 1호선 개통에 따라 도시적 사회적 변화를 실증적으로 분석하고자 하였다. 이를 위해 학문적 고찰과 선행연구 고찰을 통해 도시철도가 도시에 미치는 영향을 예측하였고, 모니터링 지표를 설정하였다. 대전광역시 도시철도 1호선 역세권 지역에 대한 모니터링 결과, 인구와 토지이용, 총 개발연면적, 지가의 변화를 통해 도시철도의 개통이 대전시의 도시계획의 흐름과 도시공간구조의 변화에 영향을 미치는 것으로 판단되었다. 즉, 도시철도가 개통됨에 따라 도시철도 역세권 중심으로 인구 및 인구활동 등이 집중 되며, 인구 및 인구활동의 집중은 상업지역을 확대를 가져왔으며, 이러한 변화는 평균지가의 상승을 가져오는 결과를 초래하였다. 이처럼 도시모니터링은 도시의 전반적인 시기별 변화를 파악하는데 유용한 정보를 제공할 수 있으며, 현재 도시를 파악하는데 중요한 역할을 할 수 있음을 알 수 있었다.

Satellite image for national land monitoring is required high resolution and natural color with multi spectral band. the image is expensive as higher resolution. We need cheap image relatively in economic viewpoint but the image serves sufficient resolution to monitor national land. We merged two images to one image and evaluated the result. the two images which are used at the merge test are high resolution(2.5m per pixel) panchromatic and low resolution(10m per pixel) multi spectral image of SPOT-5 satellite. The result of this study. We made the merge image to have sufficient resolution for national monitoring.

SAR image is not dependent on the weather condition and Sun's electromagnetic energy. But geometric distortions exist in almost all radar image, it need to be correction. The Radarsat-1 SAR images are used to monitoring of moisture acquired in May 1/1998 and May 25/1998. Radarsat-1 C band data is sensitive on moisture condition. Study area is located in Non-san site. It is made up almost agricultural area and a little of forest area. In May, Rice-planting is started in the midland of Korea. So moisture condition is undergoing many changes. Forest area need to be terrain effect removal for accurately results because it is included in layover, shadow, and so on. Results of land-cover moisture condition map are useful tool for fields of agriculture, forestry industry, and disaster.

국토모니터링에 대한 자료는 기존의 정적인 자료에서 동적인 정보를 포괄하는 방식으로 발전하고 있다. 따라서 다양한 국토모니터링 정보를 통합, 처리하여 제공하는 기술이 요구되고 있다. 이 연구에서는 현재까지 진행된 국토모니터링과 관련한 국내외 사례를 조사하고, 구축된 공간정보시스템의 특성을 정리하여 통합된 국토모니터링 시스템이 갖추어야할 내용과 설계 전략을 제시하였다.

The present study illustrates a method for monitoring the urban vegetation around Shaoxing city, Monitoring spatiotemporal changes in urban areas will become increasingly important as the number and proportion of urban residents continues to increase. The synoptic view of urban land cover provided by satellite and airborne sensors is an important complement to in situ measurements of physical, environmental and socioeconomic variables in urban settings. The results obtained have revealed a notable change in the vegetation cover in and around the City premises. In this study, we discussed methodology for measurement of urban vegetation and vegetation distributions based on band ratioing in Shaoxing city using Land sat TM imageries. A systematic analysis of the spatiotemporal dynamics of vegetation in urban areas is required to ensure a healthy sustainable environment.

The primary goal in this paper is to analyze urban growth patterns using multi-temporal remote sensing images and geographic information data. In order to accomplish this purpose, firstly data pre-processing is carried out, and then land-use maps are generated with ancillary data source by heads-up on-screen digitizing. Lastly, using the results of the previous stages, the patterns of land-use and urban changes are monitored by the proposed scheme. In this research, using the multi-temporal images and geographic information data, monitoring of urban growth was carried out with the application of urban land-use changes.

Many researchers have made a study of NPS unit-loads and the scientific evaluation method which need for formulating and enforcing a Total Maximum Daily Load (TMDL) management system and modifying a pollutant discharge loadings function. Some showed the event mean concentration (EMC) on single land-use. For the most parts, as the results showed on multiple land-uses, those cannot be used for NPS unit-loads calculation. NPS runoff shows various phenomena depending on rainfall monitoring data, therefore sampling methods and frequency for NPS monitoring must be different from the general monitoring for water quality trend assessment.
