Tracasa presents its work on the super-resolution of satellite images at the ISPRS Congress, a leading international event on remote sensing

The «Learning Super-Resolution for Sentinel-2 images with Real Ground Truth Data from a Reference Satellite» project was included in the company’s yearbook after being deemed one of the congress’s finest pieces of work

Tracasa, a public company of the Government of Navarra, exhibited its work on the super-resolution of satellite images at the Annual CISPRS (International Society for Photogrammetry and Remote Sensing) Congress, a leading international event in this field, held in Nice (France) between August 31 and September 2.

Photogrammetry and remote sensing (through the use of satellites) makes it possible to obtain accurate information from images and other sensors on the Earth and its surroundings, and to study physical processes through the recording, measurement, analysis and representation of the data obtained.

Tracasa presented its project, “Learning Super-Resolution for Sentinel-2 images with Real Ground Truth Data from a Reference Satellite”, in which it explained its SENX4 technology, which makes it possible to multiply four-fold the resolution of satellite images with Deep Learning techniques (see the complete resampled layer of the Iberian Peninsula) and improve all the metrics previously obtained in this area.

After being assessed by the ISPRS as one of the best projects presented at this edition of the congress, Tracasa had the opportunity to explain it live over the course of the meeting, which this year, in its 24th edition, managed to draw more than 1,000 attendees –with more than 100 universities and research centers represented- and receive papers from more than 500 authors.

In addition, Tracasa’s work, carried out by the team made up of Rubén Sesma Redín, Christian Ayala Lauroba, Mikel Galar Idoate (UPNA researcher), Lourdes Albizua Huarte and Carlos Aranda Torres, was selected to be part of the ISPRS yearbook after being chosen as one of the best projects presented to the company in 2020.

Presence in the journal Remote Sensing

The super-resolution project prepared by Tracasa was also recently published in the journal Remote Sensing, an international publication produced monthly by the MDPI platform. Specialized in remote sensing, it has a significant impact on the scientific community. It appears in a special issue of the journal entitled «Remote Sensing Data Fusion as a Strategy to Add Value to Earth Observation Data».

“For Tracasa, receiving this recognition and being able to benefit from diffusion of this magnitude allows us to undertake the projects to come with greater enthusiasm. It is an endorsement of the enthusiasm and efforts of a great team that has been working for years to strategically position the company at a high technological and scientific level”, explained Carlos Aranda, head of R&D at Tracasa and a member of the work team that participated in the super-resolution project.

Tracasa, a public company of the Government of Navarra attached to the Department of Economic and Business Development, renders its main services in the areas of cartography, territorial management and information systems, and offers tailor-made solutions for the modernization of public administrations and private entities, both nationally and internationally.
