TEIL W15 VOLUME VOLUME BAND XXXVIII-4

This paper will review the status of computer aided teaching advances during the last decade, with a particular emphasis on photogrammetry, remote sensing and GIS. A range of examples will be presented, many of which will be drawn from the Computer Aided Teaching Contests (CATCON), sponsored

on photogrammetry, remote sensing, and geomatics. Some best practise examples will be presented featuring prominently recent Massive Open Online Courses (MOOCs) related to our fields. The consideration of mainly free online learning resources will include a commentary on quality and perceived effectiveness.

This article reports on best practice e-learning applications in Photogrammetry, Remote Sensing and GIS. The rating is based, on results of the Computer Assisted Teaching CONtest (CATCON), a competition organised by ISPRS WG VI/2 that takes place every two years, on observation of recent

Abstract. We describe our software tool Julia for the static analysis of full Java bytecode, for optimisation as well as verification. This tool is generic since abstract domains (analyses) are not part of Julia but rather external classes that specialise its behaviour. Static analysis is performed through a denotational or constraint-based fixpoint calculation, focused on some program points called watchpoints. These points specify where the result of the analysis is useful, and can be automatically placed by the abstract domain or manually provided by the user. Julia can be instructed to include a given set of library Java classes in domains the opportunity to approximate control and data-flow arising from exceptions and subroutines. 1

Abstract: With the increasing amount of geographic vector database available over the world, the remote sensing community has a strong potential to quickly produce up-to-date geographic products. In this paper, we propose a geographic object-based image analysis to bridge the gap between the image

Commission I/2 KEY WORDS: Camera calibration, stability of interior orientation, effect of zoom, nominal camera parameters. During the last years the number of available low-cost digital consumer cameras has significantly increased while their prices decrease. Therefore for many applications with no high-end accuracy requirements it is an important consideration whether to use low-cost cameras. This paper investigates in the use of consumer cameras for photogrammetric measurements and vision systems. An important aspect of the suitability of these cameras is their geometric stability. Two aspects should be considered: The change of calibration parameters when using the camera’s features such as zoom or auto focus and the time invariance of the calibration parameters. Therefore laboratory calibrations of different cameras have been carried out at different times. The resulting calibration parameters, especially the principal distance and the principal point, and their accuracies are given. The usefulness of the information given in the image header, especially the focal length, is compared to the results of the calibration. 1
