Providing Geological Knowledge by GIS

Communication in geology is characterized by very many expressions, used in texts and lectures. Among these, nonverbal terms are much more important than in other sciences. Informations rarely reflect pure facts, rather they are expressions and results of a complex process of knowledge formation. In a geologic map for example, the structure of symbols illustrates the process of knowledge transf...

Digital Ortho-image Production for Web GIS Applications

This paper presents a true ortho-image generation scheme in urban areas for web GIS application such as urban management system. Proposed scheme includes the solution of conventional problems in normal ortho-image generation. Especially, our approach is focused on the automation and consistency of ortho-image in complex urban areas. For this purpose, we generated additionally plotted DSM (Digit...

Research on Object-Oriented Geographical Data Model in GIS

Nowadays, there are many attempts to establish object-oriented GIS in some software However, they are not accordant to object-oriented concept whole and systematically in the whole course from the process of cognizing and abstracting geographical space to the process of defining and describing GIS data model then to the process of analyzing and designing GIS. Especially, the research on common ...
