    Neue Technologien in der Forstwirtschaft am Beispiel der Apps WaldFliege und WaldKarte
    (Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Müller, Christine
    Although forestry may seem to be a rather traditional branch with little interest in new technologies the use of android apps offers significant advantages in forestry and management of natural resources. The need of foresters, forest workers and logistic companies to collect and store data in the forest is met by android devices. The android apps ‘WaldFliege’ and ‘Forest(M)ap(p)’ offer a solution for optimizing timber logistic. With WaldFliege people working in the forest can collect timber data and combine it with GPS data, photos and data of forest owners. Forest(M)ap(p) shows the position of the stacks of timber in an offline map. Places can be marked by means of the GPS but also by simply tapping on the map if no satellite signal is available. Inforst also offers measuring with UAVs in forestry. This can simplify the planning of timber harvesting or the management of forest damages. The transfer of data from the multicopter directly to the offline map in the app is in project.

    Cloud Computing für die Kalibrierung von Hochwassersimulationen
    (Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Brettschneider, Marco; Pfützner, Bernd; Fuchs-Kittowski, Frank
    Well calibrated rainfall runoff models of sufficient complexity are a necessary basis for accurate flood water simulations in order to prevent losses. Using the hydrologic modeling system ArcEGMO in a small catchment as an example, IaaS cloud computing has be proven fast and cost-efficient for short-term usage. On the other hand, IaaS cloud instances cannot replace local computers, since long-term usage is still expensive and the performance of the offered architectures can slow down a calibration process on the long run. Ultimately, cloud computing has the potential to be a useful extension of local computer capacities if state of the art computer hardware with a fair pricing is offered by IaaS providers.

    Suchmaschinen-getriebene Umweltportale – Nutzung einer ElasticSearch-Suchmaschine
    (Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Schlachter, Thorsten; Düpmeier, Clemens; Schmitt, Christian; Schillinger, Wolfgang
    In order to merge data from different information systems in web portals, querying of this data has to be simple and with good performance. If no direct, high-performance query services are available, data access can be provided (and often accelerated) using external search indexes, which is well-proven for unstructured data by means of classical full text search engines. This article describes how structured data can be provided through search engines, too, and how this data then can be re-used by other applications, e.g., mobile apps or business applications, incidentally reducing their complexity and the number of required interfaces. Users of environmental portals and applications can benefit from an integrated view on unstructured as well as on structured data.

    Smart City auf Basis von 3D
    (Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Rudolf, Heino
    3D building models are currently available or in production for many urban arias. So we have the requirement to use this data for practical solutions. M.O.S.S: developed a platform to generate and manage 3D city models. This platform offers opportunities for practical uses of the data in thematic applications. In cooperation with specialist partners applications are integrated in the platform and the city model is enriched with the results. M.O.S.S: developed a platform to generate and manage 3D city models. This platform offers opportunities for practical uses of the data in thematic applications. In cooperation with specialist partners applications are integrated in the platform and the city model is enriched with the results. It is shown that the usage of 3D building models leads to a new quality in the thematic questions, e.g. the calculation of solar radiation and clouding, simulation of environ-mental phenomenon like noise, air pollutions or flood and the calculation of heat demand in buildings.

    Offenlegung und Verarbeitung von Lärmbelastungsdaten zur Bürgerinformation und Entscheidungsunterstützung am Flughafen Frankfurt
    (Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Lanz, Günter; Kazakos, Wassilios
    In a project of Disy Infomationssysteme GmbH for Gemeinnützige Umwelthaus GmbH Kelsterbach, on one hand, environmental noise data stemming from air traffic at the Frankfurt International Airport, have been published through an interactive Web tool. On the other hand, the combination of GIS and database technologies was used to compare different models for changing the air traffic schedules with respect to the maximum number of people who would benefit from less noise during the night.

    Die Implementierung von Umweltbewertungsverfahren in einer dienstebasierten Umgebung
    (Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Kohlus, Jörn; Kompter, Elisabeth
    In the following article the results of the RichWPS project, which was promoted by the Federal Ministry of Education and Research (BMBF), are presented from the perspective of its application to perform mandatory tasks of the environmental reporting. The Marine Strategy Framework Directive (MSFD) explicitly claims the use of INSPIRE (INfrastructure for SPatial InfoRmation in Europe) for the provision and processing of data. INSPIRE is based on a network services architecture. A contribution of RichWPS in terms of the implementation of the MSFD is the transfer of assessment methods consistently in a service architecture and the development of tools for a simple and comfortable orchestration of Web Processing Services (WPS) to handle such complex processes.

    Aus Klein mach Groß: Komposition von OGC Web Services mit dem RichWPS ModelBuilder
    (Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Bensmann, Felix; Roosmann, Rainer; Kohlus, Jörn
    Distributed geospatial data and services can be used to form Spatial Data Infra-structures (SDI). Current technological developments enable SDI to process large amounts of geospatial data. In this context, Web Processing Services (WPS) can be used as an open interface standard for accessing and executing geospatial processes. Since many SDI are based on Service-Oriented Architectures (SOA), the orchestration of services is enabled by composing existing services. The results are higher services, e.g. complex geospatial applications. The RichWPS research project focuses on analysing and providing practical approaches of web service orchestration. For this, software components are developed to build a modular orchestration environment. The main client-side application is the ModelBuilder.

    Aus Groß mach Klein: Verarbeitung orchestrierter OGC Web Services mit RichWPS Server- und Client-Komponenten
    (Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Wössner, Roman; Abecker, Andreas; Bensmann, Felix; Alcacer-Labrador, Dorian; Roosmann, Rainer
    RichWPS is a project aiming at more powerful and more user-friendly support for using the OGC Web Processing Services standard (WPS) for distributed geodata processing in the Web. While we have already discussed in other publications the RichWPS ModelBuilder for geoprocessing-workflow composition as well as the RichWPS approach to geoprocessing-workflow orchestration, this paper sketches the RichWPS Server software as well as some client-side developments facilitating the effective usage of WPS processes.

    UmweltWiS: Von Umweltinformationssystemen zu „Umweltwissenssystemen“?
    (Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Dornhöfer, Mareike; Fathi, Madjid
    Environmental Information Systems (EIS) are a kind of information system, addressing either the public or business sector. Different environmental data is gathered and visualized for the user. Now there is a question whether the application of semantic technologies and the interconnection and inference of data may transform EIS to environmental knowledge systems? The given article addresses this issue and proposes a concept for an ‘environmental knowledge system’ called UmweltWiS.

    Erfahrungen mit MongoDB bei der Verwaltung meteorologischer Massendaten
    (Umweltinformationssysteme. Big Data – Open Data – Data Variety, 2015) Lutz, Richard
    The remote sensing of atmospheric trace gases investigates dynamic, microphysical and chemical processes in the Earth?s atmosphere, with the goal to understand, quantify and predict its natural variability and long-term changes. Accurate measurements of atmospheric trace gases from various observational platforms (ground-based stations, air craft, balloons, satellites) provide the data that are required for the modelling of atmospheric processes. The instrument GLORIA (Gimballed Limb Observer for Radiance Imaging of the Atmosphere), developed by KIT/IMK and FZ Jülich, an Infrared Spectrometer, which measures atmospheric emissions, was engaged in several measurement campaigns on board of HALO (High Altitude and Long Range Research Aircraft) and provided a large amount of data, which has to be managed efficiently for processing and visualisation. This paper describes the system background and the use of MongoDB for the provision of measured and processed mass data.
