description: Zu einem wichtigen Bestandteil des Luftbildarchivs des BEV zählen die Flugortungskarten, die zum Auffinden der für ein Interessensgebiet notwendigen Messungsaufnahmen dienen.
Flugortungskarten sind Übersichten, die je Flugoperat erstellt werden und das jeweils beflogene Gebiet abbilden. Es wird die Lage der geflogenen Flugstreifen sowie die Bildmittenpunkte der Messungsaufnahmen dargestellt. Weiters werden die wesentlichen Informationen des Bildfluges (Flugtitel, Archivnummer, Brennweite, Flugdatum, Bildmaßstab, Filmtyp, Längs- sowie Querüberdeckung) angeführt.

Flugortungskarten stehen im Luftbildarchiv des BEV zu jedem Bildflug seit 1949 zur Verfügung.

title: Characterization of a multi-stage focusing nozzle for collection of spot samples for aerosol chemical analysis

description: Concentrated collection of aerosol particles on a substrate is essential for their chemical analysis using various microscopy and laser spectroscopic techniques. An impaction-based aerosol concentration system was developed for focused collection of particles using a multi-stage nozzle that consists of a succession of multiple smooth converging stages. Converging sections of the nozzle were designed to focus and concentrate a particle diameter range of 900 to 2500 nm into a relatively narrower particle beam to obtain particulate deposits with spot diameters of 0.5-1.56 mm. A slightly diverging section before the last contractions was included to allow for better focusing of particles at the lower end of the collectable diameter range. The characterization of this multi-stage nozzle and the impaction-based aerosol concentration system encompassing the nozzle was accomplished both numerically and experimentally. The numerical and experimental trends in collection efficiency and spot diameters agreed well qualitatively; however, the quantitative agreement between numerical and experimental results for wall losses was poor, particularly for larger particle diameters. The resulting concentrated particulate deposit, a spot sample, was analysed using Raman spectroscopy to probe effect of spot size on analytical sensitivity of measurement. The method’s sensitivity was compared against other conventional techniques, such as filtration and aerosol focused impaction, implementing condensational growth. Impaction encompassing the multi-stage focusing nozzle is the only method that can ensure high sensitivity at Reynolds numbers greater than 2000, that can be supported by small pumps which renders such method suitable for portable instrumentation.
