- KonferenzbeitragA process model for preparation and analysis of cetacean sighting data off the coast of La Gomera(EnviroInfo & ICT4S, Adjunct Proceedings, 2015) Wittmann, Jochen; Everding, Aljoscha Marcel; Ritter, FabianOff the coast of La Gomera sightings of whales and dolphins in the context of tourism whale watching tours are recorded continuously since 1995. The tour operators work together with the German registered association M.E.E.R. e.V., which has set itself the target to evaluate the data scientifically. The aim of this thesis is to develop requirements on a process model for acquisition and analysis of this data material. The recording of the data is performed under difficult environmental conditions in the open sea. The data material should be stored persistently in a database that is accessible to both the employees (full access) and the tourists (limited access) on La Gomera, but on the other hand is also the basis for the scientific evaluation.With appropriate role and rights concepts it shall be prevented, that data is distributed too widely and the animals in the observation area are disturbed. Otherwise the requirements for simple access for all interested parties will be fulfilled. This paper proposes a web-access on the protected database and adds a data export for statistical analysis and a geographically based interface via an adequate layer structure in the GIS ArcMap.
- KonferenzbeitragA Software Architecture for the Cooperation Project HADU: (Hamburg’s Dynamical Geological Underground)(Environmental Informatics and Systems Research, 2007) Wittmann, JochenThe cooperation project on Hamburgs dynamical geological underground (HADU) intends an integrative view on recent geological subsurface processes in the region of the City of Hamburg. Measurement data resulting from geological georadar methods, geophysical ambient vibrations techniques, and conventional well databases shall be combined to a 3D-underground model. From the geological point of view, such a model will help to understand the georisks caused by the salt diapirs in the underground. The computer science part of the project concentrates on a common data handling, the visualization of the geological data, and the integration of Fuzzy-methods to handle incomplete and uncertain data. In this context, this paper presents the concept for the over-all architecture of the software system developed for the use in the HADU project. Main task for the developers was to bridge the gap between the demands of the projects partners concerning the integration of already existing, highly proprietary software modules on the one hand, and to offer an integrated data handling and analysis in regard to data consistency and reproducibility of the results on the other hand. Focused on this aspect, the paper defines the HADU software architecture and discusses its adequacy and practicability within the project contexts.
- KonferenzbeitragA Software Platform Towards a Comparison of Cars - A Case Study for Handling Ratio-Based Decisions -(Innovations in Sharing Environmental Observations and Information, 2011) Wittmann, Jochen; Markert, Johann; Plura, Sebastian; Brüggemann, RainerEnvironmental aspects often are in conflict with the criteria for a best/optimal behavior under technical aspects only. In these cases, common methods to compare alternatives and to come to a decision show methodological disadvantages. In this situation, this paper intends to demonstrate the situation firstly by giving a typical example, secondly to show, how a software platform might support the decision, thirdly, to provide different methods for comparison to demonstrate the effects of the method chosen and finally to sensitize the users for the interdependencies between the comparison method and the resulting ranking. The example will deal with the decision to find a new car according to individually scalable ratios. General data on different cars mainly are in conflict with the ratio of CO2-ratio expressing the environmental aspects of the cars to select. The paper proposes a software platform that allows dealing with these conflicting parameters by individually weighting and a flexible interface for comparison.
