A design methodology for sustainable on the earth requires a synthetic, and holistic perspective to understand natural processes and urban environments. The apperceptive, holistic landscape design methodology includes one united environment combining analysis, planning and design. In addition, the individual process needs to provide enough spatial information and demands evaluation and understanding on the impact of a design result. The perspective and vision of Ian Mcharg, as asserted in his book, Design with Nature (1969), that the earth is one superorganism is being realized with Geodesign technologies. This paper made the following research efforts which can overcome the limit of the present GIS technologies for the sustainable landscape design: Review of the previous researches, analysis of foreign Geodesign cases and applied theories, suggestion of a Geodesign methodology for landscape design, selection of Geodesign tools and technologies for the implementation of the methodology, and finally the demonstration of effectiveness and potentiality by the application of the methodology.

Geodesign was suggested by Dangermond(2009) as a next paradigm of GIS to be a future basis for spatial planning and design. Ko(2015) also suggested a geodesign methodology that uses spatial information from a landscape designer's perspective. Spatial planning and design fundamentally require creativity and efficiency but Ko's methodology did not include the creativity aspect. To complement the deficiency, this paper expand the research scope to deal with a designer's cognitive limits and to provide better experiences for the landscape designers. An interface was designed to improve the designer's creativity based on interactions that were derived from a script of landscape design. The expanded methodology for both efficiency and creativity is suggested for the interface by analyzing preceding researches. ESRI's GeoPlanner for ArcGIS, as a first geodesign software, is compared to improve the interface in terms of creativity. One of the difficulties as a thesis is that it is not easy to measure the improvement of design creativity physically and quantitatively. This paper tried to eliminate any stumbling block in supporting creativity and to help designers find new orders in design subconsciousness and to reach a new concept. In addition, the interface to express instantaneous design ideas would be a guide to overcome the designer's cognitive limits.

This paper is on a participatory spatial design methodology using Virtual Reality, which can be applied to the overall spatial design process. Participation in the current spatial design has several limitations: one-sided communication process, difficulty of understanding the given information and partial participation in the design process. Virtual Reality can be an ideal visualization tool for Geodesign and PPGIS(Public Participation GIS), which is presented as a highest step at the participation ladder. A participatory methodology is proposed to take advantage of Virtual Reality. In order to support participation through Virtual Reality in spatial design process, theories about the participation are compared to derive the new roles of Virtual Reality and the roles are formulated in the participatory spatial design methodology. By applying the methodology to the design process and implementing each stage through Virtual Reality, the design performance of each step can be verified in the methodology. As a result, design ideas can be effectively understood through Virtual Reality experiences. It is also confirmed that the interactions in Virtual Reality and participation are possible in the entire design process.

By combining the role of current GIS technology and design behaviors from the cognitive perspective, spatial conceptualization can be extended efficiently and creatively for ill-structured problems. This study elaborates the model of a conceptualization-oriented SDSS(Spatial Decision Support System) for a landscape design problem. Current information-oriented GIS technology plays a minor role in planning and design. The three attributes in planning and design problems describe how the deficiencies of current GIS technology can be seen as a failure of the technology. These are summarized: (1) Information Explosion/Information Ignorance (2) Dilemma of Rigor and Relevance (3) Ill-structured Nature of planning and Design. In order to implement the conceptualization idea in the current GIS environment, it will be necessary to shift from traditional, information-oriented GISs to conceptualization-oriented SDSSs. The conceptualization-oriented SDSS model reflects the key elements of six important theories and techniques. The six useful theories and techniques are as follows; (1) Human Information Processing (2) Tool/Theory Interaction (3) The Sciences of the Artificial and Epistemology of Practice (4) Decision Support Systems (DSSs) (5) Human-Computer Interaction (HCI) (6) Creative Thinking. The future conceptualization-oriented SDSS can provide capabilities for planners and designers to figure out some "hidden organizations" in spatial planning and design, and develop new ideas through its conceptualization capability. The facilitation of conceptualization has been demonstrated by presenting three key ideas for the framework of the SDSS model: (1) bubble-oriented design support system (2) prototypes as an extension of semantic memory, and (3) scripts as an extension of episodic memory in a cognitive pschology perspective. The three ideas can provide a direction for the future GIS technology in planning and design.
