By contrasting the traditional way in which GIS was completed that comes
with less flexible, low efficiency, and lack redundancy which cause high entry
cost, the fast development of microkernel plug-in technology provides the
lightweight, efficient and scalable solution to Geographical Information System
(GIS). This paper is to reveal the potential of microkernel plug-in geospatial
information processing technology in GIS design and practice, with the
acceptance and usage of function model called Resource loading manager(RLM) for
GIS applications, which provides a possible solution to overcome the GIS’s high
cost issue. After the short review of microkernel plug-in technology, the
possibility of GIS design with microkernel is analyzed. This paper also introduced
the composition of the whole system and the design of GIS service platform
based on middle-ware in detail.
