UAV flight at Corvara Landslide

In the frame of the LEMONADE project, EURAC – Applied for Remote Sensing Institute performed the UAV flight campaign on the 23.06.2016 aiming to produce high resolution orthomosaics, 3D point clouds as well as Digital Surface and Terrain Models.

The UAV was flying exactly the same area, considered as the most active part of the Corvara landslide (i.e.  13 hectares on air) covered in 2015. The original flight plan consists of five different flights, each of them 200 m long, 80 m wide and 60 m height.

Unfortunately, during the flight campaign of this year we faced technical difficulties because we were not able to transmit the flight plans into the automatic flight controller mounted on the UAV (control system that follows a pre-programmed GPS point route). Since one single field campaign takes a lot of effort, organization and time, the pilots decided to flight in manual mode, i.e. controlling elevation, orientation and speed during each flight. The general consideration that we agreed was to keep (i) the height of 60 m and (ii) the straight lines with the support of one observer standing in the opposite side of the landslide. The digital camera was configured to acquire one image every 2 seconds according to a flight speed of 5 m/s what gave us some images every 10 m approximately. In order to retrieve reliable results and decrease the effect of the manual flight mode, four flights were done using the same orientation and one in the orthogonal orientation.



We were able to collect 1190 images that were preliminary pre-processed to confirm the overlapping coverage. This task consisted on filtering images, converting images from raw to tiff (using Rawterapee software), assigning position to each image, and finally doing the first processing step on Pix4D software (e.g. keypoints and coarse cloud point generation and first derived digital surface model).

Successful UAV campaign at Fortebuso

The FBK team, supported by the Geological Service and the Civil Protection Department of the Autonomous Province of Trento, conducted the first data acquisition campaign at the Fortebuso landslide. A DJI S1000+ octocopter equipped with a Sony Alpha 6000 digital camera acquired images at sub-cm resolution (GSD) during three flights. Total station and GPS surveys were carried out in order to measure targets both inside and outside the landslide. The photogrammetrically derived dense point cloud contains approximately 100 mil points and it’s now used for geological analyses and monitoring purposes.

Geo-environmental monitoring using remote and close range sensing techniques

The call for abstracts is now opened for the session Geo-environmental monitoring using remote and close range sensing techniques which is convened by the LEMONADE project team at the GeoTirol 2016 conference. Submit your abstract until 27.4.2016.

Contributions to this sessions are welcome with thematic focus on environmental geology, geological and geomorphological mapping, detection and mapping of mass movements, trigger identification, monitoring of erosion, shallow and deep-seated landslides. From a remote and close range sensing perspective contributions might cover topics such as automated information extraction, time series analysis, error assessment and quality studies, multispectral sensing, topographic LiDAR, RADAR and InSAR, thermography, unmanned aerial vehicles, photogrammetry, geosensor networks, data integration and data fusion techniques.




Kickoff Meeting in Bozen

The LEMONADE team consisting of members from the 3D Optical Metrology, Fondazione Bruno Kessler (Trento), the Institute for applied Remote Sensing, European Academy of Bozen (Bozen) and the Institute of Interdisciplinary Mountain Research, Austrian Academy of Sciences (Innsbruck) met for the kickoff meeting in Bozen. The team discussed the project workplan about LandslidE MOnitoriNg And Data intEgration and planned the upcomming fieldwork in the summer period 2016.


EUREGIO Science Fund

The EUREGIO Science Fund (Tirol, Südtirol, Trentino) has funded the project LEMONADE about LandslidE MOnitoriNg And Data intEgration. The consortium consists of 3D Optical Metrology, Fondazione Bruno Kessler (3DOM FBK), Institute for applied Remote Sensing, European Academy of Bozen (EURAC), and the Institute of Interdisciplinary Mountain Research, Austrian Academy of Sciences (IGF ÖAW).
