Überlegungen zu einer Spatial Big Data Architektur im BigGIS Projekt Abecker, Andreas; Brauer, Torsten; Kutterer, Johannes; Schnitter, Karsten; Nimis, Jens; Wiener, Patrick Fretag,Ulrike; Fuchs-Kittowski, Frank; Hosenfeld, Friedhelm; Abecker, Andreas; Kudraß, Thomas In the recent years, a number of data-management and data-analytics applications and technologies under the label “big data” has found much interest among academics and practitioners. From our point of view, the respective researchers and commercial pro-viders, up to now, neglected to a large extent both the spatial dimension of potential big-data applications and their usage potential in the area of environment protection and environment management. Hence, the RTD project BigGIS investigates methods and tools for “Spatial Big Data” in three environment-related application scenarios. In this paper, some basic definitions and considerations are explained, the three applica-tion scenarios of BigGIS are presented and some initial insights regarding software architectures for Spatial Big Data solutions in the area of geo data and environmental applications are presented.

LUPO mobil - Konzepte und technologische Einblicke in die App „Meine Umwelt“ Kimmig, Daniel; Schillinger, Wolfgang; Schlachter, Thorsten; Düpmeier, Clemens; Weissenbach, Kurt Fretag,Ulrike; Fuchs-Kittowski, Frank; Hosenfeld, Friedhelm; Abecker, Andreas; Kudraß, Thomas This paper describes the concepts and the technological background of the mobile app “My Environment” („Meine Umwelt”). The main idea of this app is to merge various environment-related scenarios into a single app for mobile use. This idea dates back to the European initiative "SEIS" (Shared Environmental Information System) allowing the public to see environmental-related information within their area (“What’s in my backyard?”). To achieve this, the app “My Environment” includes three main scenarios. These are the publication of environmental information ("Inform") for interested laymen, collecting new or updating existing environmental information ("Report"), as well as providing localized information to enable people to go outside and experience nature ("Experience").

Entwurfsmuster in Android-Apps am Beispiel von Apps für die Forstwirtschaft Müller, Christine Fretag,Ulrike; Fuchs-Kittowski, Frank; Hosenfeld, Friedhelm; Abecker, Andreas; Kudraß, Thomas It is easy to develop an Android-App and even beginners in programming can create an Android-App fast. Therefore, the question arises, it is worth spending time on design and architecture of such lightweight programs. But the frequency with which new An-droid versions are released and the changing demands of the users makes it just as necessary for apps to be flexible and extendable. Inforst develops apps for forestry that run completely offline. They are just as complex as desktop applications which meet the same tasks of collection, storage and exchange of timber data. The price for apps is far below the price for comparable desktop applications though. This puts even higher pressure on developers to develop reusable software components and reduce the costs for testing and refactoring. To fulfill these demands the use of Design Pat-terns can be helpful as is shown in this article at the example of the app “WaldFliege”15used to collect timber data.

www.Wasserqualität-Online.de – Das WebGIS-basierte, deutschlandweite Bürgerportal Gutzke, Thomas; Stelzer, Marco; Gutzke, Alina Fretag,Ulrike; Fuchs-Kittowski, Frank; Hosenfeld, Friedhelm; Abecker, Andreas; Kudraß, Thomas Requirements on the quality of drinking water – based on the Drinking Water Ordinance (Trinkwasserverordnung) – are quite high in Germany. The given standards issue big challenges to the majority of the estimated 6.200 water suppliers. One part of that statutory requirements demands the publication of the drinking water quality for the public by every supplier at regular intervals for every of their clearly defined water supply areas. Conditional to size and therefore technical capabilities of the suppliers the complexity of this task is extreme and sometimes not accomplished to the full extent. This article describes the development and technical background of a unique GIS-based web portal that addresses to all German water suppliers as well as all end-consumers. Suppliers can perform their publication obligations in a convenient way and the public finds easily access to their requested information about drinking water quality all over Germany.
