out in collaboration with universities or special research institutions. Depending on the relief, different percentages of coverage were attained during the last period: Carinthia for example shows a coverage by orthophoto maps of 8596, while 4096 of the settlement region -of the Tyrol is already covered by traditional line maps at a scale of 1:5,000. C. MUNICIPAL AUTHORITIES The special goal of city administrations must be the support of all kinds of planning in structural and civil engineering, architecture, traffic, cable lines, pipe- lines, sewage systems, etc. Because of continuous changes of the settlements periodical flights are performed, their scale in general being larger than 1:5,000. The Austrian capital Vienna, the venue of this congress, is the dominating example of urban application of photogrammetry and remote sensing. Besides being a city, Vienna is also a federal province and has to satisfy both tasks. Its area of 415 km? is surveyed completely every three years at a scale of approx. 1:6,000. In the years between these flights, one third of this area is covered by aerial images which are used for the production of the digital city map on the one hand, and for real land-use mapping on the other. Apart from these regional applications, photogrammetry is used for surveying the second Vienna water pipeline, the Danube river, the roof landscape and other projects. The administration of Vienna manages its own photogrammetric department, connected to a large information system with all possibilities of visualization, established at the central computing office of Vienna. The smaller provincial capitals also apply photo- grammetry periodically for the above-mentioned purposes. Two interesting examples may be shown referring to Graz (capital of Styria) and Salzburg. In 1992 Graz performed a complete colour image flight (730 images) at a scale of approx. 1:3,700 and in 1993 a flight along its main river, the Mur. By means of these images a complete aero- triangulation was carried out, and the results (coordinates and parameters of orientation) were stored in a respective data base. Using these data, the evaluation of stereoscopic models is performed by an analytical plotter with reference to actual planning activities. Recently, the instrumentation for digital photogrammetry was installed, and cor- responding procedures are in development. In good time (1972), the administration of Salzburg started a project referring to a utility register. In order to complete this basic information for a digital city map, several flights (scale appr. 1:4,000) providing a complete coverage of the Salzburg area were carried out since 1992 . The evaluation is performed by private photogrammetric offices under 4 the supervision of the municipal authority. The project should be finished in 1996. The capitals of all the other Austrian provinces are working more or less in the same way. D. RESEARCH INSTITUTIONS In Austria there exist two important independent institutions of general research. They are: = Joanneum Research in Graz — Austrian Research Center Vienna Besides other topics both are also working in the fields of digital image processing and remote sensing. Seibersdorf near 1 Joanneum Research Joanneum Research consists of 21 institutes. One of them is the institute of Digital Image Processing with the two departments of "Industrial. Image Processing” and “Remote Sensing”. Both are working in the fields of ISPRS related to Com. V and Com. VII respectively. 1.1 Industrial Image Processing This department works on the development of novel vision systems for automating industrial production control. Emphasis is put on drafting algorithms and software systems which solve two-dimensional inspecation tasks in real time. Apart from these 2D developments, 3D measuring techniques (light sectioning) are investigated. In this topic several special projects were performed, as for example: Planetary body high-resolution terrain models, 3D navigation and reconstruction based on multiple views, surface inspection by color recognition algorithms, tunnel measuring using CCD cameras, geometrical measuring with : high-resolution area cameras and track measuring. The department serves as a "partner in innovation" for business enterprises focused on applied research in key technologies. 1.2 Remote Sensing The department processes all kinds of remote sensing (active and passive) data. The high- precision geometrical rectification of remote sensing images based DTM's is its special forte. Developments also have been related to the stereoscopic extraction of 3D terrain information from SAR image pairs and stereo-MOMS-data using automated image matching techniques. Moreover, investigations referring to SAR inter- ferometry have been carried out recently. Another research area is the development of new methods and technologies to identify natural resources, vegetation damage and natural risks. In this context the following special topics were treated: Analysis of land use, such as settlement zones, agricultural land and forest types; classification of forest damage and assessment of environmental risks, International Archives of Photogrammetry and Remote Sensing.
