GPS/GIS Abstract:
Real-time GPS and GIS Mapping As A Community Resource Management Tool

Conventional straight-line geometry of physical measurement is usually time consuming, cost prohibitive and human error prone. It is difficult to find referencing points to register an accurate location in the field and on a paper map. Global Positioning System (GPS) is a revolutional technology that is able to provide digital coordinates and elevation information for any location on the earth through the constellation of 24 satellites. Along with real-time differential correction, a data-logger and a field computer with a background map, this system is an efficient tool for data collection and data input in the field. These locational data and attributes provide an instant geographic information basis for inventory, analysis, and database management.

There is a wide variety of GPS and Geographical Information System (GIS) applications that can be used towards community resource management. For example, they can be used for site topographic survey, boundary survey, and feature mapping; for highway facilities inventory and maintenance such as signs, bridges, pavement conditions, culverts, and road types; for arboretum accession; for city street inventory and maintenance; for wayfinding, point features quick marking, events recording and path tracing; and many other environmental projects such as wetland delineation, land use change detection, and historical feature documentation.

The author would like to present a pilot study of real-time GPS applications in community resource management. This project includes an arboretum accession program, and a city street inventory and maintenance program. The study is based on a GPS receiver, a real-time SpaceNet communication satellite data correction link, a barcode system interface, a datalogger or a field computer, background maps, and a data dictionary for locational data and attributes logging. The presentation will include a detailed operational procedure of the hardware setup, software interface, background map preparation, barcode system interface, data dictionary setup, real-time data correction, GIS software integration, database join and link, logistics of the project, and other field and office operations. Finally, this paper will conclude with findings of cost, technical difficulties, and the potentials and constraints of this new technology to a wide variety of audience.

Interactive Multimedia Instruction Abstract
INTERACTIVE MULTIMEDIA INSTRUCTION: LEARNING LANDSCAPE ANALYSIS AND USE

This multimedia interactive instruction software was developed by the author after attending a multimedia workshop at Iowa State University, sponsored by a USDA's higher education challenge grant. The software is designed to help undergraduate students understand different issues of land use and analysis in environmental planning and design. Subjects covered in this tutorial software encompass overlay mapping, GIS, planning, soil suitability, storm water, watershed management, solar energy, and vegetation.

Multimedia interactive instruction is also termed computer aided instruction or computer based training. It incorporates video, movie clips, 3-D animation, voices and sounds, graphics, text, and images into a computer based training software. It offers repetitive and interactive instruction with the aid of multimedia to users who are generally unfamiliar with the subject. It is a very useful educational and presentation tool not only for training, but also for information dissemination, sales and marketing.

The author plans to explain in brief the production of this multimedia instruction software and discuss the technical and time involvement of the authoring software experience for educational purposes. The up and downsides of using this technology will also be addressed.

3D Animation Abstract
USE OF 3-D MODELLING AS AN INTERACTIVE PRESENTATION AND CONCEPTUAL DESIGN TOOL

A model is a simplified representation of the real world. Design is an interactive process and so is 3-D modelling and animation. Landscape architects develop study models (a broader meaning) of site plans and design through the use of graphic language, written communication, model building, and design language. 3-D modelling opens a new frontier in landscape architecture design visualization for designers and educators. This paper presents the experience of teaching 3-D spatial modelling. By incorporating 3-D modelling and the animation of visualization tools into design courses, students were able to visualize their designs better. More specifically, students and instructors were able to create a real-time animation of the site at a selected path with an interactive presentation that opens the spectrum of discussion. Sequential spatial experience, design languages, and design principles can be understood in a dynamic way. 3-D modelling and visualization techniques are unique and useful spatial design communication tools. These techniques also provide designers with better design ideas and decision-making processes through interactive experience, conceptualization, imagination, and judgment. This paper also assesses the impact, success and problems of this innovative design education method.
