Surveyors BUT IS IT GIS ?

چکیده
GIS as we know it is traditionally a two-dimensional static representation of space, closely related to the paper maps that were its inspiration. While various attempts have been made to define a “3D GIS” or a “Dynamic GIS”, in recent years other disciplines have moved much faster in this direction – notably some parts of computer science, computer graphics and game development. This paper looks at this situation, and suggests some remedial actions in the geography (and surveying) communities. These consist primarily of a stronger emphasis on teaching computer algorithms as applied to spatial analysis, as well as a familiarity with the basics of computer graphics and spatial data structures. I hope to show that a modest subset of these tools is sufficient to lead towards the modelling of the third dimension and time. However, one worry remains – is this still GIS?

متن کاملThe link between quality and accreditation of residency programs: the surveyors’ perceptions
Accreditation of medical residency programs has become globally important. Currently it is moving from the goal of attaining minimal standards to a model of continuous improvement. In some countries, the accreditation system engages peers (physicians) to survey residency programs. The surveyors are sometimes volunteers, usually engaged in multiple clinical and education activities. Few studies ...
