As the technology of Smart City and Digital Twin is developing, techniques to integrate BIM data of infrastructure facilities into GIS are becoming more critical. Hence, this study aims to manage BIM data representing bridge and tunnel structures through the Industry Foundation Classes (IFC) standard and to develop a method to link these IFC-compliant files to the GIS standard CityGML without loss of information. We analyze the criteria for creating BIM data for bridges and tunnels by reviewing the BIM guidelines set by each client. We use these criteria to suggest methods for data management based on InfraBIM as a specific IFC class standard. Furthermore, we perform model analysis to determine the necessary design and construction field-appropriate model process and Level of Detail (LOD). From the model analysis, we conclude that the classified BIM models can be used as base data to generate BIM models of bridges and tunnels for facility management.

In general, Digital Photogrammetry is based on independent workstation system, which is costly and has complex process. In this research, a new approach method regarding Digital Photogrammetry procedure is suggested using Web Processing Service, which is a GIS standard proposed by Open Geospatial Consortium. For the experiment, many Generic Processes were defined through WPS profiling procedure which defines standard unit for Photogrammetry, and with the defined process each server and client S/W module was implemented based on WPS standards. In this paper, many users can be expected to share and reuse unit process in WPS server through the web.

It's important to develop Metadata standard to manage a large of marine geospatial data such as observation, ocean survey, satellite image more effectively. If we use metadata in Marine GIS we can make sense marine geospatial data, make the most of marine dataset. International standard organization's work and NGIS's standard are a good example to illustrate metadata standard's importance. But we don't have metadata standard for marine dataset, so it's difficult to search and use geospatial data In this paper, we presented common marine metadata element, and composited metadata implementation schema. Finally we constructed marine GIS metadata editing tool..

This study is aimed at the surveys of cultural relics and GIS based searching system which have been partially performed in each region. The goal of this research is to construct the cultural relics management system of region and to present the plan for a nationwide data integration. Consequently, based on the standard which presents from Cultural Properties Administration constructed a spatial and attribute data. And presented the model which matches national standard for a cultural property GIS integration. Also minimized a damage possibility about the cultural ruins, confirmed an application possibility about cultural ruins information of the local government.

The purpose of this research is to study use method of mobile system for effective field management for urban facilities. GIS database could be standardized commonly useful for the site management of city facilities through standard list, standard items and standard specification appropriate for the mobile system, and this is effective to manage the city facilities on the site in real time.

It is assumed that GIS conformance certification can be important for improving geospatial interoperability. This study aims to establish the framework, methodology and model for GIS conformance testing and certification Also, as an implementation example, a pilot conformance testing for GIS metadata standard are examined.

Recently, with the development of collecting methods of spatial data, the spatial data is produced, circulated, and used in various fields of industry and research. To manage the mass spatial data efficiently, the researches on extension of the existing commercial DBMS, such as ESRI's ArcSDE or Oracle's Oracle Spatial, is making progress actively. However, the usage of the extension of the commercial DBMS Incurs an additional expense and causes an interoperability problem due to differences in spatial data types and spatial operators. Therefore, in this paper, we developed an OpenGIS Spatial Interface for Oracle, which supports a standard interface by fellowing the "Simple Features Specification for SQL" proposed by OGC(Open Geospatial Consortium). Since the OpenGIS Spatial Interface provides all spatial data types and spatial operators proposed in "Simple Features Specification for SQL", users can manage mass spatial data of Oracle efficiently by using the standard interface without additional expense. In addition, we proved that the OpenGIS Spatial Interface is superior to the Oracle Spatial in the response time through the performance evaluation.

In this study, the potential for liquefaction in the Incheon international airport was calculated by appling the standard penetration test data and laboratory test data to the modified Seed & Idriss(2001) method. The analysis was performed on the non-plastic silty layer and silty sand layer which within the depth of 20m, below 20 of the standard penetration value(N), and the ground water level. Also, each set of data was mapped by using GIS(geographic information systems) and the factor of safety for the potential for liquefaction was obtained by overlapping those layers. As a result, it was found that there exist potential hazard zone for the liquefaction partially. So, the additional detailed assessments for those are thought to be necessary.

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.

Standards are essential to facilitate the efficient use of GIS data. International Standards such as ISO TC211's 19100 series and various technical specifications from OpenGIS Consortium are some of the examples of efforts to maintain the interoperability among GIS applications. Marine GIS is no exception to this rule and in this context. developing standards for marine GIS is also in urgent needs. Using the same meaning and definition for the features commonly found in marine GIS applications is one of the ways to increase the interoperability among systems. One of the key requirements for maintaining the standard meanings for features is to build a common feature catalogue. This paper examines the concept of feature catalogue and describe the ways in which the feature catalogue can be organized. To identify the common features found in various marine GIS applications, a comprehensive search has been made to collect and analyze the features used in various applications. To maintain the interoperability with the National GIS (NGIS) system, the features used in various NGIS applications have been analyzed as well. The result of these analyses are used to create a comprehensive list of common features for marine GIS. This paper then explains the common feature catalogue for marine GIS and the provides the appropriate classification and coding systems for the common features. In addition, a registration tool for registering the common features into the standard registry has been developed in this study. This Web-based tool can be used to input features into the feature catalogue by various applications and also to maintain a standard-compliant feature catalogue by standard agencies.
