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.

Traditionally, Geographical Information System can only process static spatial data, which include geometries and attributes. Recently, According to Special attention is paid to ubiquitous computing environment, we require a u-GIS convergence middleware to efficiently process ubiquitous data and improves the existing GIS engine in order to enable converged processing of spatial and sensor data. So, in this study, we propose a design of u-GIS Convergence Middleware, which are based on the integration between GIS and USN technologies

현재 내비게이션, 물류, 지도기반 매쉬업등 공간 데이터를 활용한 다양한 응용서비스가 활용되고 있다. 또한 향후 유비쿼터스 환경에서는 모바일 환경에서 공간 데이터 및 센서를 활용한 서비스들이 출현할 것으로 예상된다. 그러나 현재 모바일 GIS 시스템들은 유비쿼터스 환경에서 발생하는 다양한 데이터들을 처리해주지 못하고, DBMS기반이 아니라 유연성이 부족하다는 문제점이 있다. 이 논문에서는 이러한 문제점을 해결하기 위해 모바일 u-GIS 데이터 처리 시스템을 제시하고자 한다.

With the rapid interest in Geographic Information System (GIS) contents, a large volume of valuable GIS dataset has been distributed illegally by pirates, hackers, or unauthorized users. Therefore the problem focus on how to protect the copyright of GIS vector map data for storage and transmission. At this point, GIS security techniques focusing on secure network and data encryption have been studied and developed to solve the copyright protection and illegal copy prevention for GIS digital map. But GIS vector map data is very large and current data encryption techniques often encrypt all components of data. That means we have encrypted large amount of data lead to the long encrypting time and high complexity computation. This paper presents a novel selective encryption scheme for GIS vector map data protection to store, transmit or distribute to authorized users using K-means algorithm. The proposed algorithm only encrypts a small part of data based on properties of polylines and polygons in GIS vector map but it can change whole data of GIS vector map. Experimental results verified the proposed algorithm effectively and error in decryption is approximately zero.

Local administration is closely related with intention of residents. Especially, a plan item is closely related with life of residents. Therefore, it has to be logical and objective solution for opinion convergence. Decision of opinion has to be in a triangular position standard and stand in a trio of criteria in standard. But, opinion convergence of residents very difficult. Recently, the technique of GIS presents method for oponion convergence with logical and objective and scientifically solution. And, this study present method for decision of intention to a complex element with GRID and NETWORK techniques of GIS. This study present optimun site of constructure with the GIS technique in consideration of a side face of transportation, technical, social economy and environments.

Digital vector maps must be compressed effectively for transmission or storage in Web GIS (geographic information system) and mobile GIS applications. This paper presents a polyline compression method that consists of polyline feature-based hybrid simplification and second derivative-based data compression. Experimental results verify that our method has higher simplification and compression efficiency than conventional methods and produces good quality compressed maps.

Nowadays, geographic information system (GIS) is developed and implemented in many areas. A huge volume of vector map data has been accessed unlawfully by hackers, pirates, or unauthorized users. For this reason, we need the methods that help to protect GIS data for storage, multimedia applications, and transmission. In our paper, a selective encryption method is presented based on vertex randomization and hybrid transform in the GIS vector map. In the proposed algorithm, polylines and polygons are focused as the targets for encryption. Objects are classified in each layer, and all coordinates of the significant objects are encrypted by the key sets generated by using chaotic map before changing them in DWT, DFT domain. Experimental results verify the high efficiency visualization by low complexity, high security performance by random processes.

국민소득 증가와 고령화 사회에 진입하면서 다양한 의료소비가 의료서비스산업에 영향을 미치고 있으며, 이러한 사회 구조 및 환경변화에 따라 새로운 질병에 대한 대응 또한 절실히 요구되고 있다. 질병 예측을 위한 연구는 기후변화와 질병, 건강행태와 질병, 사회적 위치와 질병 등 질병에 영향을 주는 많은 요인들이 있다. 그러나 이러한 요인들을 통합, 분석 활용하는 데는 해결해야 할 문제들이 많이 있다. '정부3.0 공공데이터 개방 정책' 을 통해 질병에 관련된 자료가 공개 되면서 본 연구에서는 2010년부터 2012년까지의 질병에 영향을 주는 공공데이터를 연도별로 통합하여 지리정보시스템(GIS)기반 데이터베이스를 구축하고 활용 할 수 있게 하였다. 향후 기후변화에 민감한 질병을 찾기 위해 해당기관의 자료를 활용하여 월별로 데이터베이스를 구축하고, 이를 기반으로 의료서비스의 활성화 및 효율성에 기여 할 수 있다.

Recently, various researches have been attempted to connect or integrate BIM handling construction data and GIS handling spatial data. However, it is hard to interoperate by integration between two data models because characteristics and domains of data models between BIM and GIS are very different. In this research, we propose the platform to secure efficient interoperability between BIM and GIS and define the component technologies and functions of the platform proposed in this research by analyzing the existing commercial softwares.
