Remote sensing of environment research has explored the benefits of using synthetic aperture radar imagery systems for a wide range of land and marine applications since these systems are not affected by weather conditions and therefore are operable both daytime and nighttime. The design of image processing techniques for  synthetic aperture radar applications requires tests and validation on real and synthetic images. The GRSS benchmark database supports the desing and analysis of algorithms to deal with SAR and PolSAR data.

The Contest: Goals and Organization

The 2022 IEEE GRSS Data Fusion Contest, organized by the Image Analysis and Data Fusion Technical Committee, aims to promote research on semi-supervised learning. The overall objective is to build models that are able to leverage a large amount of unlabelled data while only requiring a small number of annotated training samples. The 2022 Data Fusion Contest will consist of two challenge tracks:

Radar data and Pluviometric data for Sardinia (Italy)


The dataset contains UAV imagery and fracture interpretation of rock outcrops acquired in Praia das Conchas, Cabo Frio, Rio de Janeiro, Brazil. Along with georeferenced .geotiff images, the dataset contains filtered 500 x 500 .png tiles containing only scenes with fracture data, along with .png binary masks for semantic segmentation and original georeferenced shapefile annotations. This data can be useful for segmentation and extraction of geological structures from UAV imagery, for evaluating computer vision methodologies or machine learning techniques.


This dataset is composed of a datacube with 271 x 271 pixels, and 96 bands.  The ground truth has 271 x 271 pixels.


827 PoIs in Bogota D.C., Colombia, obtained from Foursquare. Format of the data is CSV with headers. The data include: id, geometry representation, name, category, latitude, longitude, and geohash.


The files contain the measurement data of the PAZ antenna pattern for horizontal and vertical polarization at the location of the HITCHHIKER receiver.


The data is given in ascii tabular format, fields separated by tabulators. The first column, angle, contains the angle along the long side of the antenna array, the remaining columns give the derived effective isotropic radiated power in db(W). Values are given for each angular value at consecutive bands at 9600, 9650 and 9700MHz as well as the value for the full bandwidth.


Targeting the Huangnibazi Landslide located in the southwestern mountainous region of China, which is mainly induced by the heavy rainfall and the Jiuzhaigou earthquake, we implement the self-potential (SP) monitoring system and global navigation satellite system (GNSS) on the slope. The SP and GNSS data monitored at the slow-moving stage of the landslide are supplied. 


This dataset is the model data required in the manuscript for IEEE Transactions on geoscience and remote sensing.


The dataset contains hurricane Maria-induced outage duration at the barrio level derived from nighttime lights, along with the values of cofactors from socioeconomic and physical factors that influenced the recovery process.
