Abstract

Over the past twenty-eight years, the GIS computer technology has undergone tremendous changes and advancements along with software developments and variety of analytical methods, and also in terms of scope, quality of products and operating costs. These vast changes have been observed in recent research studies, but what has so far remained unchanged and is possibly more important is that the next phase of GIS research and development should once again focus on the models and theoretical questions that always face us, and I would like to use my "framework" as a guide to deal with questions that need to be answered.
