The International Workshop on the Analysis of MultiTemporal Remote Sensing Images (MultiTemp 2019) will be held in Shanghai, China in the period August 5-7, 2019. This is the 10th edition of the workshop series that was established and founded from the RSLab in 2001 (first and sixth editions in Trento).

If you wish to stay informed about the MultiTemp conference you need to register on the MultiTemp 2019 event website (https://multitemp2019.tongji.edu.cn/info/1077/1132.htm) to keep receiving news and updates via email.

RSLab achieved very good research results in 2018 on both Earth Observation and Planetary Exploration and the related research topics. Continue Reading

Elena Donini received the award for the 2017 Best Italian Theses on Remote Sensing by the Italian Chapter of the IEEE Geoscience and Remote Sensing Society. The award was presented by Prof Antonio Iodice, who is the chapter chair. The title of the thesis is “Simulation and Extraction of Lava Tubes Features from Radar Sounder Data of the Moon” (Advisors: Prof Lorenzo Bruzzone and Dr Francesca Bovolo).

ESA engineers tested A 1:18 scale model of the RIME antenna – Radar for Icy Moons Exploration (Principal Investigator: Prof. Lorenzo Bruzzone) together with a simplified model of the JUICE spacecraft in the ESTEC’s HERTZ facility. Several tests were performed, for different solar array orientations, with the objective of collecting a set of data that can be compared with the results obtained through the simulations and thus validate the design and verification approach.

The antenna measurements were performed by rotating the scaled model and the RIME antenna along two axes, in order to measure the electric near field on a spherical surface in the vicinity of the scaled model. The near field data were then processed to obtain the far field performance, which is of particular interest because it more closely resembles real antenna performance.
This test campaign was a proof of concept that enabled fine-tuning of all relevant parameters. At a later stage, the antenna’s performance will be simulated with a high-fidelity model of the spacecraft, which will include all possible features that can influence the antenna pattern. These results will serve as inputs for the RIME instrument team to derive the overall inflight performance of the instrument.

The ESA project “Scientific Exploitation of Operational Missions (SEOM) Multitemporal Analysis (MTA)” (coordinated and developed by RSLab) successfully passed its Final Review. The project was about the development of automatic techniques for the analysis of the big data acquired by  Sentinel-2 multispectral system in in the context of three application and methodological areas:
(1) Time series analysis, focused on the processing of image time series for precision agriculture.
(2) Change detection and attribution, focused on the analysis of bi-temporal images for detection of forest disturbances.
(3) Land cover maps updating, focused on the use of recent images for unsupervised updating of thematic maps.
The output of the project was very good. For this reason ESA is funding one additional year of activities in order to apply the developed methods to the analysis of images at Italian country scale using european cloud computing infrastructures.

RSLab presented its research activities on Earth Observation and Planetary Exploration at the MUSE Science Museum in Trento in the framework of the European Researchers’ Night 2018.

On Thursday September 27, Silvia Demetri defended his PhD thesis on “Remote Sensing-Based Channel Modeling and Deployment Planning for Low-Power Wireless Networks” (supervisors Gian Pietro Picco and Lorenzo Bruzzone). The committee awarded the PhD in Information and Communication Technology.
Congratulations to Silvia!

RSLab is the coordinator of an important new project of European Space Agency (ESA) funded in the framework of the Climate Change Initiative, which is the flagship scientific program of ESA. This is the first project of this important program that has an Italian leadership.

The focus of the project is to generate high resolution time series of land cover maps (10/30 meters) at subcontinental level using multispectral and SAR satellite remote sensing images acquired between 1992 and now. The maps will be generated automatically by developing a processing chain based on machine-learning classification approaches and data fusion methodologies. The processing chain will be implemented in cloud for the analysis of the huge amount of data (big data) available.

The maps produced will be given as input to climate models for studying the interactions of land cover and changes in land cover at detailed scale on the the climate evolution. The first phase of the project (3 years) will be focused on South America (Amazon), Central Africa (Sahel) and Siberia areas where the long time series of high resolution data can significantly enhance the understanding of the climate processes.

The project started in the past days with the kick-off meeting at the European Space Research Institute (ESRIN) of ESA in Frascati.
