N2  - Spatial concerns of Web geographical informa-  tion systems (Web-GIS) are inherently crosscutting and  volatile: crosscutting because they affect multiple function-  alities of Web-GIS systems, and volatile because their status  may change often. If these concerns are not modularized  properly, the quality of Web-GIS services, particularly with  regard to adaptation and evolution, can be severely compro-  mised. This paper uses aspect-orientation to model crosscut-  ting and volatile spatial concerns. By modeling both types  of concerns, crosscutting and volatile, as candidate aspects,  one can use dynamic weaving to add or remove them from a system at runtime. The aspect-oriented approach proposed starts with the identification and specification of crosscutting concerns and follows by composing these using modeling aspects using a transformation approach, an aspect-oriented modeling technique. The conflicts that can emerge due to the composition order are also taken into consideration. Finally, this paper proposes a set of reusable GIS crosscutting con- cerns, documenting them in a concern catalogue
