Call For Papers: IEEE Signal Processing Society: “Special Issue on Signal and Image Processing in Hyperspectral Remote Sensing”

Aims and Scope

Hyperspectral imaging has recently emerged as one of the very promising technologies in remote sensing, enabling applications that may have been previously seen as impossible in multispectral imaging. Hyperspectral cameras deployed in current airborne or satellite systems can cover the visible and near-infrared wavelengths at a resolution of 10nm, with more than 200 spectral channels. This vastly increased spectral information content creates a unique opportunity for numerous applications, such as mineral identification, agriculture, environment monitoring, terrain classification, object detection, change detection, and many more. Hyperspectral imaging is also a key technique for planetary exploration, astrophysics, and non-remote sensing problems such as food inspection and forensics. Remarkably, these meaningful and important applications have led to a wide variety of signal processing problems, which have attracted growing attention and contributions from the signal processing, image processing and machine learning communities. In particular, we have witnessed developments that are far from being just a straight application of a signal processing technique. Instead, some of them turn out to provide new insights and open new dimensions for fundamental signal processing research. For example, it has recently become clear that the unmixing topic in hyperspectral remote sensing has formed a new branch of blind source separation techniques, wherein the exploitation of special source characteristics, such as local sparsity, has been found to provide very effective blind separation solutions. The same goes with the classification and detection topics, where the utilization of contextual information or combined spatial-spectral processing has resulted in new paradigms. Moreover, the recent research trend indicates that hyperspectral signal and image processing is embracing frontier signal processing concepts very quickly—this includes sparse signal processing, compressive sensing, and convex and nonconvex optimization, just to name a few.

The aim of this special issue is to gather high-quality tutorial-style articles that introduce key signal processing topics arising from hyperspectral remote sensing, demonstrate the insight and uniqueness of signal processing techniques established in this area, and/or provide overviews of the latest trends. In particular, we wish to shift the perspective from the remote sensing side to signal processing, and extract insight behind the signal processing developments happening in hyperspectral remote sensing. While this is the focus of this special issue, we may also welcome application-oriented papers that can tell a good story regarding how signal processing makes a difference.

Topics of Interest include (but are not limited to):

  • unmixing, both linear and nonlinear, and both semisupervised and unsupervised
  • classification
  • target or anomaly detection at a subpixel level
  • coded aperture and compressive sensing
  • sparse signal processing, which includes sparse regression, dictionary learning, multiple measurement vector models, etc
  • convex and nonconvex optimization
  • contextual information or combined spatial-spectral processing
  • Bayesian and statistical signal processing
  • nonlinear manifold learning, graph theoretic methods
  • dimension reduction, subspace identification, non-negative matrix factorization

Submission Process

Articles submitted to this special issue must contain significant relevance to signal processing and its application to hyperspectral remote sensing. All submissions will be peer reviewed according to the IEEE and Signal Processing Society guidelines. Submitted articles should not have been published or under review elsewhere. Manuscripts should be submitted online at http://mc.manuscriptcentral.com/sps-ieee using the Manuscript Central interface.

Witness the Launch of the next Landsat Satellite

NASA will host a two-day event for 80 of its social media followers on ­­­­­­Sunday, Feb. 10, and Monday, Feb. 11, at Vandenberg Air Force Base in Lompoc, Calif., for the launch of the Landsat Data Continuity Mission, a satellite that continues a record-breaking 40 years of Earth observations.

Landsat satellites provide the longest continuous global record of the Earth’s surface – ever. The first Landsat satellite launched from Vandenberg in 1972 and now what will become the eighth satellite in the Landsat series is scheduled to also launch from Vandenberg. This satellite, the Landsat Data Continuity Mission (LDCM), continues Landsat’s critical role in monitoring, understanding and managing our resources of food, water and forests.

A collaboration between NASA and the U.S. Geological Survey (USGS), the Landsat program provides data that shows the impact of human society on the planet – a crucial measure as our population surpasses seven billion people. Landsat data has, over time, led to the improvement of human and biodiversity health, energy and water management, urban planning, disaster recovery and agriculture monitoring, all resulting in incalculable benefits to the U.S. and world economy.

LDCM will join the aging Landsat 5 and Landsat 7 satellites in orbit to produce stunning images of Earth’s surface along with a wealth of scientific data.

NASA Social participants will have the opportunity to:

  • Hear first-hand accounts by the Landsat Mission science and engineering teams.
  • Get a behind-the-scenes tour of Vandenberg Air Force Base’s Western Range including:
    • A rare look inside the the Western Range Operational Control Center (WROCC), which provides safe control of all launches from Vandenberg. The WROCC includes the control center, mission flight control center, weather center and transportation control center.
    • Tours of the Landsat Launch Mission Control room, the LDCM launch pad & The Vandenberg Heritage Center
    • Vandenberg’s on-base private museum, located at historic Space Launch Complex-10. This visit includes historic briefings and artifacts dating to the earliest launches from the West Coast.
  • Meet fellow space enthusiasts who are active on social media.
  • Meet members of NASA’s social media team.

All sites on VAFB are subject to closure due to mission requirements

Postdoctoral position in Remote Sensing of the Arctic Ocean

The postdoc position will be hosted by the Radar Remote Sensing group at the Department of Earth and Space Sciences, in close collaboration with the Maritime Environment group at the Department of Shipping and Marine Technology. The two research groups collaborate with oceanographers and modellers at the Swedish Meteorological and Hydrological Institute (SMHI) and the University of Gothenburg.

Curiosity is the driving force behind the research at the Department of Earth and Space Sciences and our goals are to find new knowledge about space, our earth and our future energy supply. Through observations of the universe as well as earth, we make predictions about the future and promote sustainable development. To reach our goals, we develop highly sensitive measuring instruments and observational methods, as well as advanced algorithms for data analysis and theoretical models.

Shipping and Marine Technology covers a wide research field, ranging from environmental research to the development of the latest technologies for propulsion and navigation of ships. Our research aims to improve ship efficiency, marine environment, and working conditions for the ship personnel.

Information about the project

The rapid change of the Arctic region and melting of the polar ice open up for an increase in maritime activities in the Arctic region; both increased interest in shorter shipping routes between the Atlantic and the Pacific and exploration of new oil and gas fields. The expected increase in maritime activities brings an increased risk for oil spill and pollution. From an environmental perspective the Arctic region is very sensitive, much due to the low temperatures that slow down biogeochemical processes.

The aim of the project is to use archived and new satellite data to provide background information to a risk assessment study on effects and potential geographical distribution of oil pollution along prospected future shipping lanes in the Arctic and to identify future challenges. The project is funded by Chalmers Area of Advance for Transport.

Job description

The main task of the postdoc will be to compile estimates of sea ice extent, sea ice drift, ocean currents and surface wind conditions for the risk assessment. An important source of information is expected to be satellite data and satellite products. The collected data should be processed and analyzed and the resulting information should be formatted and documented for use in the risk assessment. The estimation of ocean and sea ice parameters can be done with algorithms that are available at the Department of Earth and Space Sciences. Planning of and participation in field work could become a part of the job. Methods, results and conclusions from the research are expected to be presented in scientific papers and in a report. Collaboration with researchers and Ph.D. students at both departments, as well as outside Chalmers, will be fundamental for the success of the research.

The employment is limited to a maximum of 2 years (1+1). The majority of the working time will be devoted to research, but there is also a possibility to take part in teaching or supervision of M.Sc thesis students and Ph.D. students.

Australia creates world’s first continental-scale mineral maps

The new suite of mineral maps will enable mining companies to increase the efficiency and viability of their exploration efforts.

The world-first maps were generated from a ten-year archive of raw Advanced Spaceborne Thermal Emission and Reflection (ASTER) data collected by NASA and the Japanese Government’s Japan Space Systems.

CSIRO scientists have developed software that transformed the data into a continent-wide suite of mineral maps that show information about rock and soil mineral components and provide a Google-like zoom to view images from thousands of kilometres wide to just a few kilometres. They are already changing the way that geoscientists look for mineral deposits by providing more accurate and detailed information than ever before.

The ASTER maps represent a successful collaboration involving scientists from Japan, USA and Australia. Data access and software development has been coordinated by CSIRO through the Western Australian Centre of Excellence for 3D Mineral Mapping and involves Geoscience Australia, state and territory Geological Surveys, AuScope, iVEC, NCI, JSS, NASA and the USGS.

The maps were officially launched at a short ceremony featuring CSIRO Chief Executive, Dr Megan Clark and Geoscience Australia CEO, Dr Chris Pigram at the 34th International Geological Congress in Brisbane last night.

Following the launch, Professor Yasushi Yamaguchi, head of the Japanese ASTER science team said, “Congratulations on your successful launch of the ASTER geoscience maps of Australia. It is a very good example of the ASTER contribution to the geoscience community and I am very proud of being an ASTER science team member”.

Dr Mike Abrams from NASA and head of the US ASTER science team added, “Congratulations on an impressive project. I do like your idea of producing global geoscience maps, similar to what you have created for Australia”.

The Australian ASTER geoscience maps can be obtained from the AuScope Discovery Portal, the Western Australian Centre of Excellence for 3D Mineral Mapping and Geoscience Australia. State and territory coverage can also be acquired from the respective government geological surveys.
