Sibi, S., "Adequacy of Geographic Information Systems as a Computer Aided Planning Tool"

This thesis evaluates the adequacy of geographic information systems (GIS) as a computer-aided planning (CAP) tool. Computer-aided planning is defined as: the use of a computer-based flexible information system designed to support the capture, storage, management, analysis, modeling, and display of spatial data for planning decision-making. Adequacy is examined from three distinct perspectives.

First, the components of GIS with respect to their ability to collect, store, manage, and analyze spatial data examined. Second, a case study is developed to demonstrate the implementation of GIS for planning problem-solving. The case study involved the integration of digital data within MAP 11, a raster-based GIS for Macintosh computers. Digital data were transferred from LOIS (a vector-based GIS developed for PC workstation platforms) to MAP 11. For this purpose, a prototype data integration process has been developed for data conversion between PC and Macintosh operating systems and it is shown how a GIS can be successfully implemented for planning tasks. Third, the potential of current GIS to function as a CAP tool within the planning process is evaluated. While GIS have the ability to help planners in their routine day-to-day planning tasks, a broader use of GIS in planning is restricted by two factors. Current GIS are capable of only providing support for spatial data aggregation and data visualization. For planning tasks that require detailed data analysis and data modeling, current GIS support is far short of what is required. That is, GIS are not functionally well advanced. Additionally, current GIS are complex systems to operate by persons without strong computer skills. Very elaborate training in the operation of GIS is a prerequisite for successful use of this technology within planning.

Further progress through in-built analytical models and simple user-interfaces within GIS are called for before GIS can function as a full-fledged CAP tool.
