The article of G. G. Wilkinson is dated, and this is significant in a field that is rapidly evolving. Nonetheless, in my point of view, the author’s argument is still valid today. He talks about uncertainty and data structures in remote sensing and GIS. Sophisticated technologies and remote sensing don’t automatically solve the problem of delimitating boundaries. Even with technology development, classification is still a complex task. It is like trying to create boundaries where the world is actually maybe more like a continuous landscape. We are trying to define distinctive class of land cover or topographic zones for example, but in reality is there a frontier between different types of land? It partially explains why uncertainty is attach to any kind of techniques in remote sensing. Taking the limits of remote sensing techniques into account, the author evaluate different procedure and use of data structure. He thus suggests that part of the further development is to identifying the best techniques and technology development that will allow the best representation of the phenomenon that is intended to be represented by the remote sensing data. Although the problems of errors and uncertainty are unlikely to be solved easily even with technical development in data structures or with visualization techniques such as 3d environment and virtual reality.
