Supporting Geo-Workflow Management through Object Activity Model
Liou, Jaeik ; Ryu, Keun Ho ;
Journal of the Korean Association of Geographic Information Studies, volume 4, issue 2, 2001, Pages 1~16
Management of geo-workflow's changes is one of growing issues and requires more advanced ways and methods to deal with heterogeneous modifications and interactions of process, activity and event over time. A few dominant workflow models have coped with these subjects. There is, however, little consensus for explanation of six dimensions with regard to actor, activity, space, time, reason and effect. This study begins with examining environments of six dimensions and the Hexad model is proposed to elucidate the causes and results of a wide variety of geo-processes and activities. In this paper, we will introduce Hexad Object Activity Model making it possible to interpret manifest motivations, conditions and actions. Full descriptions of six dimensions are often useful for applying to the handling of diverse activities particularly requiring to clarify actor's goal and role at a specific time and space.

The Purpose of this study is to provide an effective way of developing GIS to UIS at the local level. For this purpose, the study typologically reviews the developing processes of UIS and utilizes a case study as research method. As the case, the study selects three types of UIS such as FM based UIS(Kwacheon), Urban Planning based UIS(Cheungju), and LIS based UIS(Taegu Nam-Gu). Based on these three UISs, the study concludes as follows. First, the developing process of GIS to UIS began with isolated approach through integrated model and finally to internet UIS. Second, UISs follows similar processes to that of GIS construction. Third, local governments focus on the development of FM based UIS of which construction budget is financed by the central government. Based on these findings, the study provides policy alternatives for the successful construction of UIS.

Using satellite image and GIS, spatial distribution characteristics of black locust forest as honey plant area was identified and analyzed. Upon the result, the most suitable area for black locust forest was selected through the integration analysis of transparent overlay. The variables used for spatial analysis such as topography(elevation, aspect, slope), soil, drainage, distance from urban area, land use, meteorological elements were considered. Based on the suitability analysis, it was clarified that the integration of linear and factor combination technique is greatly efficient method for the most suitable area. In addition, Gokung, Imgo, Chungtong, Hwanam area were shown to be suitable in Young-chun Area. As the result of suitability analysis for honey plant area of black locust in Young-chun using satellite image and GIS, the present portion of potential distribution area was produced about 42.53%. The portion of most suitable area for honey plant area of black locust was about 26.77%. Finally, the total area for honey plant area of black locust in Young-chun came up to
. Additionally, satellite image and GIS were expected to be significant tools for suitability analysis of honey plant complex area.
Comparison of Bio-Optical Properties of the Yellow Sea and the East Sea using SeaWiFS Data
Jeong, Jong-Chul ;
Journal of the Korean Association of Geographic Information Studies, volume 4, issue 2, 2001, Pages 38~45
Three lines from
E of the East Sea and the Yellow Sea were chosen to extract spectra of normalized water leaving radiances. Comparative analysis of the OCTS algorithm and SeaWiFS(OC-2) algorithms was presented here. OCTS algorithm have more overestimate than SeaWiFS(OC-2 algorithm) for detecting chlorophyll concentration. Atmospheric correction algorithm that is excluded the effect of SS in the case 2 water need for long term ocean environmental monitoring of the East Sea and the Yellow Sea. And, considered the effect of CDOM and SS, bio-optical algorithm have to be developed in this research.
The Study of Modeling in Web GIS-System using UML - The special reference of Chungbuk National University -

Journal of the Korean Association of Geographic Information Studies, volume 4, issue 2, 2001, Pages 46~60
This study proposes the Web-based GIS system based on distributed object management and conceptualise system architecture and its methods specifications through UML(unified modeling language). By using class diagram and creating prototype based on UML and reverse engineering, our conceptual shape file model is proposed to illustrate an integrated architecture. Through system analysis and software configuration management, this study enables to not only improve pliable capabilities for problematic domains and increase abilities for analytical domains when user requirements are dynamic, but also assist effective and consistent maintenances of large software systems.
GIS Implementation at Korean Local Government: Analysis through Employees' Perception Survey
Koo, Chamun ; Lee, Kun ;
Journal of the Korean Association of Geographic Information Studies, volume 4, issue 2, 2001, Pages 61~70
In the process of GIS implementation, various unexpected problems could be uncovered. If neglected, these problems would make GIS implementation much more difficult. In order to improve GIS implementation along with alleviating these problems, the following are recommended. First, in establishing GIS master plans the Korean government has to have a better understanding not only on financial and technological feasibilities, but also on organizational culture, employees' experience and perception on new technology, etc. Second, to avoid overlapping investments and technical problems such as discrepancies between digital maps drawn by different agencies and between traditional parcel maps and digital maps, a unified and/or coordinated GIS map-making system and departmental coordination are required.
