Technical Committees


The Geoscience and Remote Sensing Society has established a number of Technical Committees to actively promote discussion and advances in areas of member technical interests. Activities of the Technical Committees include networking within the scientific topic, organization of thematic workshops, education of young professionals, organization of special sessions at IGARSS along with hosting committee meetings open to all IGARSS participants. 

Upcoming Webinars

IGARSS 2021 Activities

At IGARSS 2021, the IEEE GRSS Technical Committees will be present with 21 invited sessions. The program will be launched in April 2021!

GRSM TC Column

TC Flyer

The Technical Committee flyer (version 2020) summarises briefly the main mission of the Technical Committees and presents the current chairs.

Virtual Reality TC 3D App

The GRSS Society has developed an app that can be viewed on your cell phone that better describes the kinds of things that each of the Technical Committees works on. Download it for (Android | iPhone | Direct Download). Each TC has curated content in the app.

  • ESI TC: The app shows a CityGML model of the historical center of Santiago de Compostela and was provided by Tecnalia (
  • FARS TC: The app shows a world map of the RFI (Radio-Frequency Interference) contamination experienced by the SMAP (Soil Moisture Active/Passive) satellite mission. RFI signals interfere with the normal operations of the satellite. The color indicates the percentage of data that is lost due to RFI; the height is the intensity of the RFI signals.
  • IFT TC: The app shows a 3-D model of the Tandem-L Synthetic Aperture Radar (SAR) satellite with a deployable reflector antenna and digital feed array. The model is based on a CAD model provided by AIRBUS/DLR and was remodeled by Andreas Ley, TUB.
  • IADF TC: The model for the app was generated based on Multispectral LiDAR point cloud data, intensity rasters, and digital surface models (DSMs) at a 0.5-m ground sampling distance (GSD) and shows hyperspectral data at a 1-m GSD as well as very high-resolution RGB imagery at a 5-cm GSD. The data was acquired by the National Center for Airborne Laser Mapping, NCALM, and was used in the GRSS IADF Data Fusion Contest of 2018 (
  • GSIS TC: The app shows a hyperspectral image acquired by the HySpex-VNIR over Munich, Germany, specifically of the famous football stadium “Allianz Arena”. The HySpex-VNIR sensor provides 160 bands (400 nm – 100 nm). The shown data was acquired and processed by the German Aerospace Center (DLR) in Oberpfaffenhofen.
  • MIRS TC: The app shows three facades that have been reconstructed by image-based multi-view stereo and processed by the abstraction pipeline of [1]. The surface texture smoothly changes between measured colors and ambient occlusion. [1] “Depth Map Based Facade Abstraction from Noisy Multi-View Stereo Point Clouds”, Andreas Ley and Olaf Hellwich, GCPR 2016, pp. 155-165, 2016
  • Standards for Earth Observations: The app shows a 3D dataset of Granitic Terrain in the parts of Hyderabad depicting hills and valleys topography, India, using IRS LISS IV and Carto DEM. It was provided by Naresh K. Mallenahalli and Kidambi Seshadri, National Remote Sensing Centre (ISRO), and is licensed under CC BY-NC-ND 4.0.

GRSS Technical Committees

The following list provides the current technical committees, a brief statement of interest, and their main mission. Click on the icons for more information!

Earth Science Informatics

The Earth Science Informatics Technical Committee (ESI TC) provides a venue for informatics professionals to exchange ideas and share knowledge. It aims at advancing application of informatics to geosciences and remote sensing, assessing technology to support data stewardship and management, and promoting best practices and lessons learned.

Frequency Allocations in Remote Sensing

The Frequency allocations in Remote Sensing (FARS) Technical Committee goal is to interface between GRSS and the radio-frequency regulatory world, and keep track of spectrum allocation issues that impact the geoscience community.

Geoscience Spaceborne Imaging Spectroscopy

The Geoscience Spaceborne Imaging Spectroscopy Technical Committee (GSIS TC) provides a community of practice for all stakeholders engaged in spaceborne imaging spectroscopy with an emphasis on geoscientific applications.

Image Analysis and Data Fusion

The Image Analysis and Data Fusion Technical Committee (IADF TC) of the Geoscience and Remote Sensing Society serves as a global, multi-disciplinary, network for geospatial image analysis and data fusion.

Instrumentation and Future Technologies

The Instrumentation and Future Technologies (IFT) Technical Committee of the Geoscience and Remote Sensing Society serves as a global, multi-disciplinary, network to foster international cooperation in advancing the state-of-the-art in geoscience remote sensing instrumentation and technologies.

Modeling in Remote Sensing

The mission of the Modeling in Remote Sensing Technical Committee (MIRS TC) is to serve as a technical and professional forum for advancing the science of predicting remotely sensed observations from first-principles theory.

Standards for Earth Observations

About Standards for Earth Observations Mission Standards activities provide a proven path to advancing technology implementation and are a natural extension to the technical activities carried out within IEEE Societies
