Open GIS Consortium(OGC) provides with Simple Features Specification for OLE/COM which is a system object technology of interoperability and reusable capability. In this research, the Spatial Reference System(SRS) component is developed based on the OGC specification using ATL. The component presents 44 map projections and transformations between different geographic coordinate systems utilizing the seven parameter(Bursa Wolf) and Molodenski's methods, a user can set up all objects and its attributes comprising SRS and can create SRS and save its setting using predefined text, WellKnownText. The Spatial Reference System component can be easily implemented into the variety of GIS software so that it reduces the developing time for a system and defines new reference system without difficulty.

The uniqueness of Korean funeral culture has produced the problems such as forest indiscreet cemetery development and increase of cemeteries for those without surveying family due to negligent management. To solve these problems, government and social organization have recommended a use of cremation, charnel house and cemetery. The objective of this study is to develop a cemetery information management system which cemetery managers who are GIS laypersons are able to understand GIS functions easily and use conveniently. Cemetery tasks should be done not only in the office but also at the field. In the office, they perform GIS functions like input, modification and so forth using a desktop. And at the field, they perform the functions like simple input, inquiry using a PDA(Touchscreen) that can receive GPS signal. As various open source softwares were used to build the system, the expense was reduced largely, and we could expect the possibility that it can be utilized in more cemeteries by adding more various functions.

Specially, location information can say that is important information in this ubiquitous environment and solutions of new GIS system to utilize this are required. Examine method to improve web geography information service system because this paper uses XML and presented specific implementation result. Through internet. it planed various geography information that offer in form of service that do not receive restriction of heterogeneous system environment. Also, did thing that is easy when request service about geography information that user need and deliver fast by purpose. Supplement and to improve open-ended and XML of form normalized use and developed existent web geography information service. So that can use map service in web browser without setup of application program that buy expensive GIS software or offer in each company design and implement.

This paper presents a development of the Data Logger System to transmit the outcome of the waterlevel measuring instrument using the pressure sensor by means of the CDMA network. In or order to set up the real time monitoring the waterlevel measurement system, we have designed the waterlevel sensor, communication terminal and repeater, and data logger. Furthermore, its application for the GIS(Geographical Information System) with management sever system and software solutions have also been developed to minimize the property damages from the flood disaster which occurs every year in the river.

This paper proposes an easy method to develope user interfaces for the GIS using local server automation In the developing stage of user interface the most important thing is to apply effective windows programming techniques and component software supporting techniques. This study shows an user interface developing method using the local server automation and Visual Basic programming. For a case study, the study constructs its user interface which performs map overlaying, referencing attribute tablet, graph analysis, drawing up of thematic amp.

High-resolution remotely sensed data such as SPOT-5 imagery are employed to study the effectiveness of the watershed segmentation algorithm. Existing problems in this approach are identified and appropriate solutions are proposed. As a case study, the panchromatic SPOT-5 image of part of Beijing urban areas has been segmented by using the MATLAB software. In segmentation, the structuring element has been firstly created, then the gaps between objects have been exaggerated and the objects of interest are converted. After that, the intensity valleys have been detected and the watershed segmentation have been conducted. Through this process, the objects in an image are divided into separate objects. Finally, the effectiveness of the watershed segmentation approach for high-resolution imagery has been summarized. The approach to solve the problems such as over-segmentation has been proposed.

This study proposes an easy method to develope user interfaces for the GIS using OLE automation. In the developing stage of user interface, the most important thing is to make the best use of effective windows programming techniques and component software supporting techniques. Using the OLE automation and Visual Basic programming, the study constructs an user interface as case study which performs map overlaying, referencing attribute tables, graph analysis, drawing up of thematic map.

Satellite image processing software should be able to support interoperability that is to enable consumers, citizens, large and small businesses and governments to make the fullest possible use of the world's spatial data and spatial processing resources. The goal of interoperability is to perform hands-on research, development, testing, fielding, and validation of potential and existing interoperable geoprocessing technologies. In this paper, component based architecture for fast interoperability is designed to maximize interoperability among the OpenGIS components specified in the OpenGIS abstract specifications and implementation specifications and to mix up the OpenGIS components and the fast access mechanism for high performance.

The two key elements of the Geographic Information System(GIS) are (1) Data base management of land resources information as computer files, and (2) Software ability to analyze and map this information. More geometrically corrected SPOT derived land cover information and digital topographic infornation from digitial elevation model (DEM) were integrated as input data of GIS in order to create landscape modelling. The ultimate goal of this GIS is to establish the use of physiographic data as an intergral part of the comprehensive planning process in order to avoid significant environmental and economic problems.
