By the year 2030, the 20 km long highway section Aarau-Birrfeld of the Swiss national road A1 will be expanded from 4 to 6 traces. As an integral planning basis for all project participants, the Swiss Federal Roads Office (ASTRA) commissioned a high-resolution and highly accurate 3D model of the complete infrastructure. At the beginning of 2018, BSF Swissphoto was contracted for the extensive surveying and processing tasks, which included the combination of different measurement methods as well as the combination of the resulting data sets for a georeferenced visualization of the project area. The goal of the project was to deliver a 3D model that would enable the planning of all necessary activities from the preliminary to the executive project without the need for further site visits of the project area by the planning team. The various products enabled the engineers of ASTRA to achieve a high level of confidence already in the planning period and to minimize costs for additional surveying work during construction.

Limited availability of building land and push effects to the surroundings of regional centres ask for innovative approaches to create affordable and eco-friendly living space. Based on surveys with home seekers, transitory flats and matching mobility offers have been elaborated and combined with GIS-based densification potentials and settlement types respecting location and target groups. For application in planning practice, the WohnMOBIL construction kit offers decision support tools for communities and constructors at different intervention levels.

For surveying tasks to document glacier levels and to evaluate the mass balance, measurement data with centimeter accuracy is required. With the RTK (Real Time Kinematic) − capable low cost GNSS in use, measurements in the required accuracy range are possible. The combination of userfriendly software and low cost GNSS hardware is an ideal basis to develop a “SmartRTK” prototype for the requirements of high alpine working areas. “SmartRTK” is a compact, robust and lightweight receiver-antenna unit that can transmit the RTK position to the smartphone.

Indoor positioning and navigation for specific buildings, e. g. in the public sector, is a current requirement for many building operators. Since satellite-based technology, which has been researched, tested and used practically outdoors for many years, is not available inside buildings, other technological approaches have been analyzed and prototyped for several years. The most widely used approach is the use of Bluetooth beacons. This paper shows weaknesses of this methodology based on a metrological investigation and proposes an alternative approach using Pedestrian Dead Reckoning, supported by Bluetooth Beacons and the navigation model used. The results are shown in a prototypical indoor navigation system. Furthermore, an outlook is given on how method and technology can be

Coarse woody debris as a structural element in rivers is controversial. The positive aspects from an ecological point of view are in contrast to the negative aspects from the point of view of the transport infrastructure, flood protection systems and land use. Coarse woody debris brought in as part of renaturation projects is therefore particularly in the public eye. However, there are no reliable data collections on this. Therefore, in a first step, a prototypical infrastructure for recording the mobility of coarse woody debris should be designed and developed. This article presents the initial situation and the chosen approach. Based on a requirements analysis, the conception, development and testing of a prototypical sensor platform took place.

Today, most meadow-breeding birds are endangered due to mowing. The detection of their nests with the help of UAVs (unmanned aerial vehicles) promises less effort and disturbance. However, there are considerable uncertainties concerning the disturbance of the breeding birds. This article proposes an approach and presents first results on how the effects of disturbance caused by UAVs can be measured at breeding-bird sites on cultivated pastures. During the research project „FHprofUnt 2018: Farming 4.0 im Grünland“, the effects of disturbance by UAVs were investigated at different flight altitudes, by measuring the heartbeat-rate of a breeding Eurasian Curlew (Numenius arquata). In addition, the heartbeat-rate response caused by raptors flying over and other disturbances was measured. The results show that different flight levels of the UAV caused different heartbeat responses. Also, the increased heart-rates measured as a reaction to UAVs are comparable with responses to overhead raptors. In this article the method to investigate the heart-beat response and first results were presented. In the course of this Project further birds will be studied to increase the significance of the results. The selection of parameters regarding the disturbance of the birds is discussed.
今天，由于割草，大多数草地繁殖的鸟类都濒临灭绝。在无人机的帮助下探测它们的巢穴可以减少工作量和干扰。然而，对繁殖鸟类的干扰有相当大的不确定性。本文提出了一种方法，并提出了如何在养殖牧场上的鸟类繁殖地点测量无人机引起的干扰的影响的初步结果。在FHprofUnt 2018: Farming 4.0 in grnland研究项目中，通过测量繁殖中的欧亚鸻(Numenius arquata)的心率，研究了无人机在不同飞行高度对干扰的影响。此外，还测量了猛禽飞过和其他干扰引起的心率反应。结果表明，不同飞行水平下无人机的心跳响应不同。此外，对无人机的反应所测量的心率增加与对头顶猛禽的反应相当。本文介绍了研究心跳反应的方法和初步结果。在这个项目的过程中，将进一步研究鸟类，以增加结果的意义。讨论了考虑鸟干扰的参数选择。

Increasing traffic safety, especially for vulnerable road users (VRU), is a societal concern that could be supported by spatial analyses and models. In this study, European cities and regions are investigated with regard to providing relevant data. A structured evaluation of 14 smart cities revealed that the variety of published transport data is big. In total, we found the number of data sets, which could be relevant for modelling hazardous zones in the road space, to be rather low.
