Genomic imprinting occurs when allelic effects depend on their parental origin. These parent-of-origin effects (POE) occur because of epigenetic DNA modifications during gametogenesis according to the sex of an animal. Animal breeding programs give little consideration to imprinting, although its relationship to important traits has been shown in different agricultural species. To incorporate imprinting, a previously proposed model (imprinting model) contains the genetic effects of the sire and dam, and it provides an estimate of the variance component due to POE, which is referred to as imprinting variance. Large volumes of data are sometimes available for commercial populations, so the dimension of mixed-model equations can become very large or even excessively large when estimating imprinting variances and other genetic parameters. To address this issue, we replaced the genetic effect as dam with the effect of the maternal grandsire in the imprinting model. When combined with appropriate weightings of the observations, this replacement yields an imprinting model with a parsimonious number of genetic effects for male parents and ancestors of slaughter animals, and it enables the inclusion of large volumes of data. In addition, we derived an equivalent model to facilitate the direct estimation of POE and their prediction error variances. We applied the parsimonious model to 1,366,160 fattening bulls as well as a pedigree of 2,637,761 ancestors to investigate the relevance of POE for beef performance in dual-purpose Simmental. We analyzed the killing-out percentage, net BW gain, carcass muscularity, and fat score as slaughter traits. The parsimonious model was applied as both linear and generalized linear versions with a logit-link function. The proportions of the total genetic variance attributable to POE ranged between 8.6% and 17.1%. For 3 of the 4 traits, the maternal gamete accounted for a greater proportion of the imprinting variance. The effects of POE and their reliabilities were estimated for up to 27,567 bulls and all traits, where the reliabilities ranged between 0.38 and 0.99. Thus, our new parsimonious model is appropriate for estimating the imprinting variance using large pedigree data sets. Our results highlight the need to consider POE in genetic evaluations. © 2017 American Society of Animal Science. All rights reserved.

Following the latest developments in Remotely Piloted Airborne Systems (RPAS) industry and attending some of the most prominent fairs related to the field of geomatics one easily recognizes that it is RPAS, which is strongly pushed into the civilian market. It really is of interest, if official authorities like National Mapping Agencies (NMAs) are starting to implement the RPASs technology within their specific data acquisition processes - to establish alternatives to their traditional manned photogrammetric survey flights. The European Spatial Data Research organization (EuroSDR), representing European NMAs and research organizations of currently 17 European states, is following UAV developments since end of 2004, where an ongoing activity was created, to continuously update their members on the developments in this technology. As systems consolidated, new impetus was given to more deeply explore the potential RPAS for national mapping. Today first national mapping agencies have already used RPAS based data for first experiments in mapping. Several NMAs are discussing on the future role of this technology within their agencies. This report will try to give an overview on the current situation on the use of RPAS in European mapping agencies. Based on the input from some selected NMAs, their expectations on RPAS technology, the fields of use they foresee in their countryspecific surroundings and - exemplarily - first experiences with this type of technology will be presented. Even though the use of RPAS in NMAs is still new, substantial technical and operational benefits become obvious already. With that, the paper will try to give a state-of-the-art report on the current activities and overall acceptance of RPAS technology in European photogrammetric mapping.

The Vorderwald, Hinterwald and Limpurg cattle are native breeds located in Baden- Württemberg in the southwest of Germany. In this study pedigree data are used to evaluate the genetic variability of these breeds. For each breed two reference populations were defined. For each reference population the effective population size as well as the effective number of founders and of ancestors was estimated. The results for Vorderwald and Hinterwald cattle revealed that the genetic variability is on a solid level, derivate of a effective Population size ranging from 104,8 to 165,7 according to the estimation method. The effective population size of the Limpurg breed with values between 28,6 and 45,4 is quite small. Recommendations for future management are given. © Verlag Eugen Ulmer, Stuttgart.

The Lake Constance region is well-suited for testing cross-border issues in Europe. Therefore, the mapping and cadastre authorities of Baden-Wuerttemberg, Bavaria (both Germany), Austria and Switzerland jointly launched a pilot project: the geospatial cadastral and topographical data maintained by the authorities was prototypically transformed to the data models defined for the European Spatial Data Infrastructure (INSPIRE). These transformations were tested using the model-driven approach of the Technische Universität München as well as the format-driven approach of the AED-SICAD AG coordinated by Runder Tisch GIS e. V. In this article, the project's starting point, goals and results are described and the two transformation approaches are compared.

As part of the research project «Prototypic development of a mobile GIS-application in the context of INSPIRE, Copernicus and IACS» (= Integrated Administration and Control System; equal to InVeKoS in Germany) concrete added values achieved by INSPIRE data were investigated for mobile experts. The outcomes were proved during a field trial by a mobile system (Client). The main object of this research project is the development of an intuitive and easy-to-learn GUI (= Graphical User Interface) taking account displays of various sizes (e.g., Smartphones or Tablets). The prototypic implementation of the mobile application is based on an Android operating system. The benefits of EU-wide spatial data infrastructures (SDI) were established by means of different use cases in the fields of land consolidation, cadaster and land use. The capability of the prototype was evaluated in the presence of governmental representatives within a field trial in the region of Lake Constance in September 2012.

During the last years geo-information market has moved. After a period having a strong emphasis on the protection by law of the author and by law of the producer of the database the users information freedom stepped in the centre of attention. Because of new technologies in long-distance exploration and products like air-photos with a ground-resolution of even better than ten centimetres the official data-protectors say that the protection of personal data is threatened. The author investigates the problem, whether geo-data are personal data and must say yes on regard of local geo-data under current German law. This law is not satisfactory for companies and users of geo-data. Therefore the author proposes an unambiguous solution: geo-data must be taken out of the area of protection by personal-data law. On the other hand a connection of geo-data with personal data can be allowed in principle only by the permission of the concerned person.
