Trying to estimate variations of the riverbed is basic and important for river management. When new dam constructed in upstream and a structure were planned, impact of the riverbed changes in downstream should be considered for stably maintained and sustained rivers in the future. In this study, long-term riverbed changes analyzed using aerial photographs in Naeseongcheon. Also applying one-dimensional numerical model, GSTARS analyzed the effects of bed deformation in critical points. Based on Changing Patterns of long-term riverbed, it is possible that after the dam was built, to explore how to manage Naeseongcheon.

Recently, BIM(Building Information Model) is widely applied to all stages of SOC (Social Overhead Capital)facilities life cycle from planning to maintenance. While BIM is an analysis tool focussing the inner space of facilities, GIS is principally applied to analyzing relationship between facilities. Therefore, integrating BIM and GIS, we expect to get a potential synergy effect in aspects of effective information management and various analysis for SOC facilities. This paper deals with prioritizing SOC facilities for applying BIM/GIS integrating platform to local governments. First, investigate facilities required by law, and identify SOC facilities suitable for SOC characteristics. Second, analyze the effectiveness and applicability of BIM/GIS integrating platform applying each facility. For the purpose, we quantify effectiveness and applicability in aspects of UIS management and GIS functions. Lastly, prioritize the SOC facilities applying BIM/GIS integrating platform.

The purpose of this work is to investigate correlation between
concentration and NDVI (Normalized Difference Vegetation Index) in North East Asia. Geographically weighted regression techniques were used to evaluate the spatial relationships between GOSAT (Greenhouse Observing SATellite)
measurement and MODIS (Moderate Resolution Imaging Spectroradiometer) vegetation index. The results reveals that
concentration to be negatively associated with NDVI. The analysis of Global Morans' I index and Anselin Local Morasn's I showed spatial autocorrelation between the overall spatial pattern of
and NDVI. Ultimately, there were clustered patterns in both data sets. The results show that carbon dioxide concentration shows non-random distribution patterns in relation to NDVI clusters, which proves that intense development activities such as deforestation are influencing carbon dioxide emission across the area of analysis. However, as the concentration of carbon dioxide varies depending on a variety of factors such as artificial sources, plant respiration, and the absorption and discharge of the ocean, follow-up studies are required to evaluate the correlations among more related variables.

The work establishing effective development and conservation plan and identifying current usage of national territory is an important task of the nation. In spite of the investigation being executed by law up to about 60 different, collecting information, method and time are different between them, so it causes duplication of the budget and policy confusion. And land use listed in the cadastral book officially represents the status of land use, but it is not easy to change according to current use. Therefore collection and information in a consistent manner is necessary to build up. In this study, for the national territory including public waters and underground space, we would like to analyse current land use information collection method and suggest system construction, legal system improvement and information utilization strategies. For the accurate and consistent land management, as a result, 3 dimensional land(include underground, public water and sea etc.) use status inspection and information management is needed. And the new act should be enacted and exclusive organization also be designated.

Recently, the number of disasters has been seriously increasing. The total damages by the natural or man-made disasters during the past years resulted in tremendous fatalities and recovery costs. It is necessary to have efficient emergency evacuation management which is concerned with identifying evacuation route, and the estimation of evacuation and clearance times. An emergency evacuation model is important in identifying critical locations, and developing various evacuation strategies. In that existing evacuation models have focused on route analysis for indoor evacuation, there are only a few models for areawide emergency evacuation analysis. Therefore, we developed a mesoscopic model by using Cube Avenue and performed evacuation simulation, targeting road network in City of Fargo, North Dakota. Consequently, a mesoscopic model developed in this study is used to carry out dynamic analysis using network and input variable of existing travel demand model. The results of this study show that the model is an appropriate tool for areawide emergency evacuation analysis to save time and cost. Henceforth, the results of this study can be applied to develop a disaster evacuation model which can be used for a variety of disaster simulation and evaluation based on scenarios in the local metropolitan area.

In this study, the concept of spatial big data and effective ways to build a spatial big data system are presented. Big Data is defined as 3V(volume, variety, velocity). Spatial big data is the basis for evolution from 3V's big data to 6V's big data(volume, variety, velocity, value, veracity, visualization). In order to build an effective spatial big data, spatial big data system building should be promoted. In addition, spatial big data system should be performed a national spatial information base, convergence platform, service providers, and providers as a factor of production. The spatial big data system is made up of infrastructure(hardware), technology (software), spatial big data(data), human resources, law etc. The goals for the spatial big data system build are spatial-based policy support, spatial big data platform based industries enable, spatial big data fusion-based composition, spatial active in social issues. Strategies for achieving the objectives are build the government-wide cooperation, new industry creation and activation, and spatial big data platform built, technologies competitiveness of spatial big data.

This study has a research objective to suggest detailed rules and principles to transcribe geographical names in English for English version electronic map service. For this, guidelines which are used in English transcription of local geographical names in Korea and English transcription situations of Korea geographical names in foreign electronic map service were examined. Examining results of current situations showed the English transcription method of home and abroad geographical names caused the chaos because it is not homogenized. In order to identify easy and preferred transcription method for foreigners among English transcription methods about the geographical names which are used together like this, the preference of English transcription methods of the geographical names was examined targeting foreigners. Survey results showed that foreigners prefer to transcribe in Roman character (Romanization) with its semantic word together than just to transcribe the Roman character. Reflecting this preference research results, our country's geographical names were classified as Natural features, Cultural features and man-made structures, and Administrative units and the detailed English transcription rules and principles of each geographical names were suggested.

This paper analyzed the flood propagation characteristics of each flood elevation due to failure of embankment in Muju Namdae Stream using recursive call algorithm. A flood propagation order by the flood elevation was estimated by setting destruction point at Beonggu and Chasan small dam through recursive call algorithm and then, the number of grids of each flood propagation order and accumulated inundation area were calculated. Based on the flood propagation order and the grid size of DEM, flood propagation time could be predicted each flood elevation. As a result, the study could identify the process of flood propagation through distribution characteristic of the flood propagation order obtained from recursive call algorithm, and could provide basic data for protection from flood disaster by selecting the flood vulnerable area through the gradient pattern of the graph for accumulated inundation area each flood propagation order. In addition, the prediction of the flood propagation time for each flood water level using this algorithm helped provide valuable information to calculate the evacuation path and time during the flood season by predicting the flood propagation time of each flood water level.

In recent years, according to the increase of interests in indoor space, various researches are being carried out for the construction and services of indoor spatial information. BIM data is very useful to build indoor spatial information. Accordingly, many studies for the use of BIM data on GIS part are in progress. In order to take advantage of BIM data on GIS part, the conversion technology for building indoor data and visualization techniques are required. However, most of the previous researches are focused on the conversion technology to construct indoor spatial information by importing BIM data into GIS applications while there is few research on visualization. In this study, an indoor LOD(Level of Detail) model is proposed to apply to on indoor facility management system when indoor data was constructed based on BIM data for the linkage between BIM and GIS.

As ICTs are more advanced, in the current Smart Society that can be characterized by the terms of real-time, mobility and customization, the area of Geospatial Information is required to react to the needs of the society in more practical ways. Because Geospatial Information is getting more accepted as one of the very basic social infrastructure for everyday life activities in all sectors of life. In accordance, the legal basis of convergence Geospatial Information services are described on Geospatial Information Industry Support Law(Article 2, Item 7 & Article 4 Item 5). But it is required to come up with more detailed and practical definition of convergence GIS with more detailed supporting policies. In this context, this study aims at investigating what the needs of Geospatial Information services are in the Smart Society, and suggesting the policy directions and realization strategies of convergence GIS based on spatial hierarchy from global to local.
