Computer assisted capture and processing of attribute data requires semantic models which demand methods different from those applied by geometrical models. A completely new range of problem are linguistic aspects of semantic modelling. The present paper seeks to point out common features of semantinc modelling in linguistics and image processing. This is shown by means of a transformation concept (" real world - iconic level - symbolic level") and systematically ordered examples ("semantic nets", "system of concepts”, "unprecise concepts”, "inexact distribution”, "inadequate methods”) KURZFASSUNG Die konsequente Entwicklung digitaler Photogrammetrie führt notwendigerweise zu Aufgaben völlig neuer Art ("Paradig- masprung" ). Rechnergestützte Extraktion und Verarbeitung von Attributdaten benötigt semantische Modelle, welche andere Methoden erfordern als geometrische Modelle. Ein ganz neuer Problemkreis in diesem Zusammenhang sind linguistische As- pekte bei semantischer Modellierung. Die vorliegende Publikation versucht, Gemeinsamkeiten semantischer Modellierung in Linguistik und Bildverarbeitung herauszustellen. Dies geschieht anhand eines Transformationskonzepts (" reale Welt - ikonische Ebene - symbolische Ebene") und systematisch geordneter Beispiele (" semantisches Netz", "unscharfe Begriffe" , " unscharfe Verteilungen" , " nicht angepaBte Methodik" ). 1 A PARADIGM SHIFT, ITS ORIGIN AND ITS by the new approach. CONSEQUENCES Analytical photogrammetry limits modelling to just the ge- ometry of the image. This naturally makes available only a very narrow range of the great amount of information con- tained in the image. Carriers of geometric information are image coordinates.

A paradigm shift in any discipline is to be understood as the overall, radical change of a closed set of concepts and rules into another closed set of concepts and rules of both technical and/or non-technical nature.

The treatment of this type of information, however, requires not only a dramatic change of tools but also a new way of "seeing" the image content since well established mathemat- ical models like those applied in analytical geometry are no longer satisfactory. The step from analytical to digital processing is represented by the fact that by this approach the entire analogue im- age becomes available to the computer in numerical form. Geometrical data are now supplemented by a scale of gray values. The paradigm shift proper (Ackermann, 1995), how- ever, did not occur when analogue methods were substituted by analytical ones but when these gave way to purely digi- On the other hand, it is evident that geometry and semantics tal processing by taking advantage of the entirely new set of cannot be separated: each object in an image has its very possibilities with the consistent use of the possibilities offered ^ specific coordinates, but coordinates which do not designate 7 International Archives of Photogrammetry and Remote Sensing.
