Abstract

A new field of technology, GIS has emerged with the development of computer technology and is now in a state of drastic evolution and development. This research discusses the present situation of the overall GIS field, the development of GIS, and features of the present development of GIS technology. It also investigates and analyzes relevant issues, such as the uncertainty in topological relations which is caused by the inaccuracy of, and uncertainty in, GIS spatial data, spatial reasoning, spatial searching, spatial-searching language, the theoretical development of topological relations, the trend of GIS development, and the problems in the development of GIS in the 21^st century.
