2D Interface to a 3D Environment A Proof-of-Concept: Coupling Two Software Applications for a Web-based Public Participation GIS

The inclusive Web-based Public Participation GIS (WPPGIS) domain has developed from the interactions of three principal domains: Public Participation (PP), Internet and GIS. Each two domains create distinct sub-domains: PPGIS, Web-based PP and Web-based GIS, each of which has been researched in its own right. A successful WPPGIS utilizes the dominant properties of the above sub-domains to create a viable system. The combination of the various characteristics, result in some inner tensions between the different components. The high level of PP and GIS Technology are in some conflict. The high PP requires maximising the inclusiveness and empowerment of the public, which then requires simplifying the system to the lower common denominator. On the other hand, GIS Technology pushes forward, an area that is not a natural 'habitat' for the general public, thus creating a tension between the general public and the technology. PP requires multiple communication and information channels. When addressing visualisation information, there are numerous challenges to display the information to the general public. The Internet media requires significant resources of Hardware, Software and “Humanware”. Although the physical resources are constantly becoming more available, the non-physical resource “Humanware” will always play an important role especially when interacting with 3D environments (which require additional skills). Thus, the need for a simple, light 2D interface to a 3D environment could assist in contributing and complimenting existing WPPGIS. This project examined the development of a WPPGIS that links a 2D map to a 3D environment. The client interacts with a 2D map, selecting an origin point of view and a target point; thereafter, the system would generate a 3D rendered image that would subsequently be displayed back to the client. Unfortunately, the system was not completed in the given time. However, the principle features of the system are described and the various stages for future development are identified.
