After the annexation of Austria into the German Reich the “Berufsordnung der Offentlich bestellen Vermessungsingenieure“ (ObVI) was introduced in 1940. By analysis of documents in the German Federal Archives (Berlin) statements about the political orientation of the profession and the licensing procedure are possible. Within the group of ObVI the former “Ingenieurkonsulenten fur Vermessungswesen“ were the third largest group. The surveyors had to take the licensing procedure or they had to close their offices. The number of finally approved ObVI's is significantly lower than the number of independent surveyors in Austria in 1938. The result of the approval process was like in German Empire since 1938 a market adjustment. As part of the process, the political reliability and the ancestry of the candidates has been verified. In some cases, the authorization was denied for political reasons. In most cases, the rejection was based on age or lack of skills.

Innovative solutions are required to manage problems related to the steadily increasing traffic in densely populated areas. Among them, air pollution plays a dominant role. The idea of the Air Pollution Information System (APIS) is to monitor the air quality on a continuous basis with mobile devices and combine the data with measurements taken at stationary sites. Public transportation vehicles (preferably buses or tramways) serve as test vehicles. During the service hours of these public transportation means, air pollution data are measured en-route together with the positions of the buses or tramways. These data are transmitted to a processing center where the results are available in near real-time. The innovative feature of the project is the continuous acquisition of air pollution data where continuity refers to both position and time. For the covering abstract see ITRD E122175.
