Recent advancements in
internet mapping technology, efficient geospatial data management systems, and
availability of different GIS API’s have revolutionized the way in which the
geospatial data is being used, shared and represented through distributed
systems for business applications. However, development of powerful, highly
functional, yet cost- and time-effective enterprise WebGIS business systems
requires a very robust and highly scalable architecture. The architecture
should have the inherent characteristics of rapid development, a well-defined
object library and at the same time it should comply with the existing
geospatial interoperability standards defined by Open Geospatial Consortium
(OGC). On the other hand, development of extendible distributed business GIS
systems requires the presence of tailor-made inbuilt models available as
modules which can be extended further by readily implementable user-interface
templates supported by object modeling environment which allows for custom
design and delivery of the processes and map output. There are various
commercial and open source web mapping solutions which offer a great deal of
flexibility and functionality. Nevertheless, they restrict the user community
with certain limitations, in terms of functionality, cost or complexity. This
necessitates, defining a new approach which efficiently caters the user
requirements and not limiting them with aforementioned shortcomings. This paper
aims to evaluate various architectural alternatives for delivering robust?distributed GIS business solutions and
also attempts to give an account of an implementable instance of a WebGIS
architecture which can cater the multi-user and multi-industry requirements.
