This article did an outstanding job of emphasizing the importance of data as it relates to the effective use of GIS. On the surface, what is obvious and visible is the presentation, delivery and the graphic nature of GIS. What is essential to know and be aware about, however, is the underlying data that supports the GIS and applications; and the fact that a large percentage of the data comes from many different sources and is not homogenous in format. That one fact, by itself, presents a huge challenge in effectively combining data from multiple sources, in a timely manner. The secondary challenge is ensuring that the data are logically and correctly associated with each other. Data translation and (ETL) processes certainly are not the most flashy aspects of GIS, however, they essentially provide the solid infrastructure that enables the flashy applications and uses to exist.
