SOAPBOX
Insularity and Progress

Simon Greener

   My 20 years in IT and GIS range from general IT on mainframes to GIS consulting in business and academia to GIS Manager at a large Australian company. The thread linking these experiences for me is how important databases are in data management. When I entered GIS, we lacked generic database products for managing spatial data. Databases 101 taught me the values databases bring to IS management: first, the model, embodied in the catalogs at the heart of commercial databases; second, the logical separation of application from implementation. We had to wait until the 1990s for databases to deliver these accessibly and affordably, via object-relational products like Oracle Spatial, Informix IDS, and PostGIS.

   Unfortunately, uptake of these products within GIS has been slow. I want to suggest a possible non-financial reason for this.

   Sometimes I think I must have two heads. In building an enterprise-class, flexible, stable, open, extensible, and cost-effective GIS infrastructure for my company, I chose a commercial database in preference to “enterprise” products from a large player in GIS. When I try to explain why to my peers, I use arguments drawn from my computing science training, promoting management principles informed by good theory and proven in practice.

   Most of my peers walk away unconvinced. This may be because I don’t use lucid, digestible arguments that draw on my peers’ experience. Or it may be because of something my colleagues share with the many students I have lectured and mentored a problem endemic enough in GIS to warrant this Soapbox.

   I have been concerned awhile that some higher education institutions unintentionally promote the notion that “GIS = skill with vendors’ products.” Now, I do not contest the quality of these products, or the motives of vendors in gifting institutions with their software. But the consequence is that when it comes time to implement geographically aware solutions, the learned assumption is: if it is geographic, you must use a GIS; or, worse, you must use a GIS from vendor x.

   I often think the fascination of GIS vendors with physical file formats harks back to the pre-database computing of the 1960s: so many seem to subscribe to a version of the old adage “nobody ever got fired for buying IBM.” The only thing that’s changed is the vendor’s name.

   Is our industry too insular? Pontifications about “how special Geographic Information is” might be good for morale, but hardly for sound decision-making. Is our professional education too insular? Are we so familiar with a few vendors’ products that we won’t step outside the comfort zone to investigate “non-proprietary” solutions?

   The answers are not simple, but surely one of our problems is an industry Zeitgeist that fosters a “cradle to grave” approach to software acquisition. Thus, organizations invest their key GIS infrastructure in single-vendor stovepipe products. While this investment makes life easy for GIS managers, it makes it hard to convince them of the value of non-traditional products like databases. Truth is, such “safe” investments make information systems restrictive, inflexible, and costly. They also delay the uptake and development of computing technologies that lie at the heart of the latest “open systems” revolution.

   Our industry’s response to this revolution has been to convince itself that the latest incarnation of this or that GIS will work in an open computing environment. Father knows best: the familiar products really can offer choice in developing fully spatial IS.

   I beg to differ.
