This paper studies on urban fire station layout planning based on GIS. Compared and analyzed the results of traditional
method and the method based on road network and service area in GIS. Paper indicated the shortcoming of traditional
model used in planning, and proposed a new method based on GIS service area analysis model for improving the layout
of fire stations in order to without or reduce the blind spots and overlapping. In the end, on the basis of the analysis result
and the actual cases study, an optimized adjustment scheme is proposed.
Conceptual modeling is one of the most vital aspects of digital map generalization study, but at the same time it is
probably the least understood. The relationship between spatial data generalization in GIS and map generalization is very
close. However, distinctions exist at the same time. Based on analysis of massive references, the interrelationship of
multi-scale, manual map generalization, digital map generalization, geographic database, cartographic database and
conceptual modeling are discussed. This paper proposes and tests a simple conceptual modeling for spatial data
generalization in GIS.
