Enterprise GIS is not a Package

It seems that some organisations continue to regard GIS as a commodity application package: something that can purchased, plugged in, and voila - GIS for the business.  I started thinking about how these organisations may have come to adopt this view.

Perhaps there are 3 broad views of GIS:
  • Desktop application
  • Standalone system
  • Enterprise capability
Looking back, GIS has traditionally been provided by 'fat client' desktop applications such as MapInfo, ArcGIS, GeoMedia, Manifold, gvSIG, etc. (there is a nice list of GIS software on Wikipedia).  These applications have in general been geared towards the use of proprietary file based formats such as shp, tab, e00, dwg, etc.  As GIS grew from project based applications to departmental systems, they evolved to employ multi-user databases for storage, but still maintained the two-tier, fat-client architecture.  GIS vendors marketed their GIS Systems as replacements to the drawing office paper and mylar maps i.e. as standalone, seamless map repositories.

I think those original standalone GIS systems can be thought of as the first beasties that crawled out of the sea and into a new world of land and air.  They took the first step from paper to the digital world - but that was just the beginning.  The data has evolved to take advantage of its new surroundings; we realised that we have many other datasets that could be indexed geographically, and many other areas of the business that could benefit from the power of spatial technologies to integrate, analyse and visualise data.  GIS was no longer just the digital drawing office, it provided capabilities that were sought after across the whole organisation.

This evolution has been driven by a desire to speed up business workflows, enhance services, reduce costs and improve decision making.  These drivers have required that location should be captured and used during every task in a workflow where it helps - and that turns out to be pretty much everywhere.With this realisation it is clear that GIS is no longer a standalone system - it is a set of enterprise-wide capabilities that need to be accessible to all business systems.

I was rather puzzled recently when a UK Police force went to the market for a 'GIS System'.  In talking with the procurement officer, he appeared to regard this as any other commodity purchase; something that could be acquired and plugged in within 30 days to replace their existing GIS - software vendors only need apply.  Well good luck to them.  You can easily imagine how central to police operations geography is (CBS's TV show 'The District' featured GIS scenarios prominently). Buying a standalone GIS is not going to provide them with the benefits that they will want and expect, but until organisations evolve their definition of GIS then I guess some procurement folks are going to struggle to buy what is really needed.

Good post. It is useful for getting clear picture about GIS Systems. Thankyou.
