Final Stakeholder Workshop

On Monday 23rd April 2018 the stakeholder and closing workshop of the research project LandslidE MOnitoriNg And Data integration (LEMONADE) took place at eurac research (Bozen, Italy). LEMONADE is funded by Euregio Science Fund of the European Region Tyrol, South Tyrol, and Trentino.

The workshop was attended by scientists and practitioners from the field of remote sensing, natural hazard management and environmental monitoring. The presentations gave insights into the project results comprising topographic LiDAR, photogrammetry, synthetic aperture radar, and data integration strategies for landslide monitoring. Further talks were given by representatives of public authorities concerned with mapping and risk management and representatives of companies working in the field of 3D geodata acquisition.

Final Project Meeting

The final project meeting of LEMONADE will take place on 23rd of April 2018 in Bozen, Italy. The Euregio-funded project LEMONADE aims to evaluate the abilities, potentialities and limitations of new remote and proximal sensing methods for monitoring ground deformations and mass movements. The project tested and integrated SAR data, UAV and terrestrial images as well as terrestrial laser scanning to monitor three different landslides in the Euregio area located in
the Schmirn valley (Tyrol), Corvara (South Tyrol) and Forte Buso (Trentino).

New instruments for the Corvara Landslide: Permanent DSLR cameras and C-band corner reflectors

Recently, new instruments to improve the monitoring of the landslide were installed on the Corvara test site:
Six C-band corner reflectors were mounted in order to make use of ESA’s recently launched Sentinel 1 mission. In addition, three permanent DSLR cameras were installed on the Corvara study site. The cameras are programmed to shoot two pictures a day to have a continuous monitoring of the landslide. Two systems are powered by a solar panel and one is fed by household current.

UAV flight at the Corvara Landslide

After 2015 and 2016, on 21 and 22 June 2017 the third UAV flight on the Corvara landslide has been carried out successfully. The data is currently processed to generate a orthomosaic as well as a 3D point cloud and to compare it with the previous acquisitions.

Second survey campaign in Fortebuso

A second survey campaign in Fortebuso was realized in October 2016 over an over of approximately 150 x 100 m. The work included a UAV field campaign coupled with Total Station and GNSS survey in order to measure the position of several targets both inside and outside the landslide. The image block includes 232 images with a mean GSD of about 8 mm. Among the surveyed ground points, 6 points were included in the photogrammetric processing as GCPs whereas 6 points were used as cjeck points (CPs) to evaluate orientation accuracy. RMS errors on CPs resulted 8 mm (x), 11 mm (y) and 7 mm (z, vertical). The dense image matching extracted a point cloud with a mean spatial resolution at GSD level (around 8 mm). With the support of the Geological Service, the areas supposed to be “active” according to the periodic monitoring activities were identified. Then vegetation (trees) was filtered out and the cloud better aligned with the output of the previous campaign (June) by applying an ICP algorithm on the stable points of the area. Further analyses are now in progress to understand landslide movements.
