The new semester has started

The new summer semester has started and therefore our drones are used in different projects and field courses. In this year’s UAS course in the international Master’s program (Master of Science, M.Sc.) in Geospatial Technologies, different sensors will be used to monitor the renaturation of a small river stream near by Münster. The students will work in the following groups:

 

1. Image Analysis

2. OpenDroneMap and QGIS workflow

3. SenseBox

4. Sensors and platforms

5. Web portal

6. ESRI cloud services

7. Project management

 

We are looking forward to an exciting project.

First test flights with new payload: Wildlife radio tracking system

Our team member and student Pia Pickenbrock is currently writing her thesis on radio animal tracking using our MD4-1000. She reports:

Last week we conducted first flights with a new equipment for the survey of wild animals. In the long term the goal will be a system that can assist in locating individuals equipped with telemetry transmitters. The material was prepared and assembled in the context of a bachelor project in the the institute of landscape ecology. In this project it is planned to use the drone as an intermediate station for telemetry signals of animal tramsmitters. The signals are received with a RTL-SDR-dongle and are forwarded to a ground station, where they are reconverted to audio signals. There a surveying person might use them to locate an animal via auditorially sensed signal strengths.

The test flights with the quadcopter MD4-1000 showed that the, in some parts quite bulky equipment, had no considerable impact on either drone system or flight characteristics. It consisted of a Raspberry Pi computer and several other small hardware parts mounted on a platform under the quadcopter and a H-antenna attached to the landing skids.

New article published in MDPI Drones

Is it possible to detect traces of fluorescent powder from insects or small mammals using unmanned aerial systems?

This exciting question was asked by students in their project work (MSc landscape ecology), which took place during the summer semester 2017. The results of this pilot study have now been published in the international MDPI Journal Drones.

The publication is avaiable here

Seminar: Processing and Analysis Workflows for UAS-Borne Spatial Data

This project seminar aimed at developing open and reproducible workflows for processing and analysis of very high-resolution imagery acquired by UAS. Participants explored the use of free and open source software (FOSS) and Docker technology to create workflows covering the complete processing chain of an ecological study from the raw data to the final analysis results. The experiments provided valuable insights into the potential but also the constraints of the applied tools.

Students develop new concept to support river monitoring programs

The integration of UAS-based remote sensing methods in existing river monitoring programs (e.g. water framework directive) can provide new prospects for large-scale monitoring purposes. However, until today the integration of small aerial systems has so far been poorly researched and accordingly presents an interesting research gap. In this course, the aim is to develop an innovative UAS-based concept for the monitoring of heavily modified rivers using the example of the Münstersche Aa. In addition to the elaboration of possible application scenarios (e.g. success control of restoration measures, river structure mapping, environmental monitoring), different UAS sensors and analysis methods are tested. The results will be presented in front of the Municipal Civil Engineering Office (City of Münster) in October 2018.

UAS-Workshop ‘Geospatial Technologies’ with international student participants

During the summersemester 2018 the third international UAS-Workshop ‘Geospatial Technologies’ takes place, gathering more than 27 students out of 12 countries at the institute for Geoinformatics (IFGI) and the Institute of Landscape Ecology (ILÖK). All students are very enthusiastic and engaged in many activities around the project. The focus is set on geodata acquisition by UAS, low-cost LIDAR and ‘in situ’ field instrument for renaturation and monitoring issues along the river Aa, SW of Münster. The collected and analysed geodata will be fused and visualized in a cloud-/web-based geodata portal by the end of July 2018. Once again the WWU GEOCOPTER-team is in charge of administration.

First MD4-1000 (Microdrones) flight with 3D-printed 360° GoPro imaging system

End of June 2016 a first test flight of our new MD4-1000, fitted with a 360° GoPro-Gimbal (consisting out of 5 GoProm Cams) along the upper river Aa was successfully carried out during this semesters Geospatial Technologies workshop. The 360° Video data will be part of a scientific visualisation project at the IFGI. The Quadcopter md4-1000 from the german manufacturer microdrones belongs to the fleet of the IFGIcopter since october 2015. Its typical field of usage is geoscientific multispectral imaging, carrying sensors like Tetracam or others.
