Description

Phase unwrapping (PU) is a fundamental yet challenging step in Interferometric Synthetic Aperture Radar (InSAR) data processing, directly determining the accuracy of topographic reconstruction and deformation measurement. The ill-posed nature of PU under noise, decorrelation, and phase discontinuities makes it one of the most difficult problems in radar remote sensing. This full-day tutorial provides a comprehensive and systematic overview of InSAR phase unwrapping, covering theoretical foundations, algorithmic advances, and the latest developments in AI-driven approaches.

  1. Ill-posed InSAR Phase Unwrapping - This section introduces classical ill-posed PU theories and algorithms such as Minimum Cost Flow (MCF), SNAPHU, and PUMA. These methods rely on the assumption of phase continuity to infer the unwrapped solution from noisy wrapped observations. While widely used, such assumptions limit their robustness in regions of rapid deformation, low coherence, or severe noise. The speaker will analyze the mathematical principles, strengths, and inherent challenges of these traditional methods.
  2. Non-ill-posed InSAR Phase Unwrapping - The second part presents the formulation of a non-ill-posed observation model that establishes a direct and stable relationship between the wrapped phase differences and the sought absolute phase. This formulation breaks the traditional dependency on the phase continuity assumption and achieves a conceptual shift from ill-posed to well-posed modeling. Representative algorithms, such as the Two-Stage Phase Unwrapping Algorithm (TSPA), will be discussed, demonstrating improved performance in large-gradient and discontinuous terrain scenarios.
  3. Large-scale InSAR Unwrapping - The third part introduces the envelope sparsity theorem and its application in large-scale PU. The theorem proves the consistency conditions between local cluster-based and global unwrapping results. Based on this principle, a low-dimensional, parallelizable framework is constructed to solve large-scale PU efficiently. This framework significantly reduces computation time and peak memory usage, making practical large-area and time-series InSAR processing feasible.
  4. AI-driven InSAR Phase Unwrapping - The final section explores the emerging integration of artificial intelligence in PU. The tutorial introduces deep learning frameworks such as PGNet, BCNet, and PU-GAN, as well as benchmark datasets including InSAR-DLPU. These models leverage AI’s strong feature representation and learning capabilities to overcome the limitations of phase continuity assumptions and enhance algorithm robustness. Furthermore, recent progress in self-supervised learning and interpretability will be discussed, offering new perspectives for data-driven InSAR analysis.

This tutorial is highly relevant to the IGARSS community as it bridges classical physical modeling with modern AI methodologies. It aligns with IGARSS’s central themes in radar remote sensing, Earth observation, and geospatial data science. By combining theoretical rigor, algorithmic innovation, and real-data demonstrations, the session will provide participants with both a deep understanding and practical skills to tackle next-generation InSAR phase unwrapping challenges.

    Grasp the mathematical formulation of the PU problem, including phase wrapping, ambiguity resolution, and the implications of ill-posedness caused by noise, decorrelation, and phase discontinuities.

  2. Distinguish between ill-posed and non-ill-posed PU formulations.

    Recognize the assumptions underlying classical algorithms (e.g., MCF, SNAPHU, PUMA) and understand how non-ill-posed modeling eliminates the phase continuity dependency, enabling stable solutions in large-gradient or discontinuous regions.

  3. Implement and evaluate large-scale unwrapping strategies.

    Learn the principles of envelope sparsity and consistency conditions for distributed unwrapping, and understand how parallelization and low-dimensional optimization frameworks can accelerate large-scale InSAR processing.

Description

Synthetic Aperture Radar (SAR) imaging is a key remote sensing technology, enabling high-resolution observation independent of weather and daylight conditions. Applications range from environmental monitoring and disaster response to infrastructure and defense analysis. In the last few years, deep learning has transformed SAR image processing, achieving outstanding performance in detection, classification, and change analysis. However, most deep learning approaches are purely data-driven, often overlooking the fundamental physical properties of SAR imaging—such as coherent scattering, speckle statistics, and geometric distortions.

This tutorial introduces participants to the emerging paradigm of Physics-Aware Deep Learning (PADL) for SAR, where physical models and learning-based methods are integrated to achieve improved robustness, interpretability, and generalization.

We focus on SAR despeckling as a representative case study: a long-standing problem where the synergy between physics and AI clearly demonstrates its benefits.

The tutorial covers:

  • Physical origins of speckle noise and statistical modeling;
  • Deep-learning approaches;
  • Physics-aware training strategies (supervised, unsupervised and self-supervised learning) that embed SAR priors, imaging geometry, and speckle distributions;
  • Self-supervised and simulation-to-real learning paradigms;
  • Evaluation metrics preserving radiometric and structural consistency.

A hands-on session will guide participants through implementing and evaluating a physics-aware deep despeckling model on open datasets such as Sentinel-1. We conclude with a discussion on uncertainty quantification, interpretability, and reproducibility.

By combining theory and practice, this tutorial provides a forward-looking perspective on how Physics-Aware Deep Learning can redefine SAR image restoration, offering physically consistent, trustworthy, and generalizable AI solutions for the next generation of Earth observation.

Tutorial Learning Objectives

After completing the tutorial, participants will be able to:

  1. Understand the physical mechanisms of SAR imaging and speckle formation.
  2. Implement and evaluate a physics-aware deep despeckling model.
  3. Apply self-supervised and simulation-to-real training strategies for real-world data.
  4. Assess uncertainty and interpretability in SAR deep learning pipelines

Prerequisites

This tutorial is designed for participants with a basic background in remote sensing and introductory experience in machine learning. A basic understanding of SAR imaging is recommended, including coherent image formation, radiometry, and the physical origin of speckle noise. Familiarity with statistical models for speckle (multiplicative noise, Gamma distribution, ENL) and concepts such as coherence and multi-looking that can support a deeper comprehension of the physics-aware techniques presented is helpful but not mandatory.

Participants should also be comfortable with the essential principles of machine learning and deep learning, including supervised learning, loss functions, regularization, and gradient-based optimization. A basic understanding of convolutional neural networks and exposure to deep architectures such as encoder-decoder models or transformers is helpful but not mandatory.

From a practical standpoint, attendees are expected to have basic Python programming skills, including familiarity with NumPy and Matplotlib. A minimal knowledge of PyTorch—tensors, modules, simple training loops—is suggested, as the hands-on session will guide participants through the implementation and evaluation of physics-aware deep despeckling models. Code templates and Kaggle/Colab-ready notebooks will be provided to minimize setup overhead.

Description

As Earth observation (EO) technologies accelerate into a new era of hyperspectral constellations, AI-enhanced analytics, digital twins, and climate services, the value of this innovation depends on one essential skill: the ability to communicate insights clearly, accurately, and compellingly to the people who rely on them. From decision makers navigating climate risks to communities experiencing environmental change, effective communication determines whether EO data becomes actionable knowledge or remains inaccessible technical output.

This tutorial introduces practical, future-oriented communication strategies tailored for the next generation of remote sensing research. Participants will learn how to translate advanced EO outputs into narratives that illuminate societal relevance, fuels cross-sector collaboration, and supports climate resilience. The session blends lecture, case studies, and hands-on activities to offer a toolkit for transforming complex datasets into accessible stories aligned with IGARSS 2026’s focus on the future of Earth observations.

A central component of the tutorial is crafting narratives that connect modern EO capabilities to real-world impact. Through examples involving climate extremes, water-energy-food security, cryosphere change, and disaster response, participants will practice turning technical insights into messages that resonate with diverse audiences, including policymakers, educators, local communities, and interdisciplinary partners. We highlight how next-generation EO systems can be embedded into broader societal narratives about adaptation, sustainability, and environmental justice.

The tutorial also addresses one of the most pressing communication challenges in future EO: conveying uncertainty transparently in an age of predictive models, probabilistic products, and AI-generated insights. Participants will learn approaches for framing uncertainty in ways that build trust and clarify risk without oversimplifying scientific nuance.

Finally, the session integrates principles of Diversity, Equity, Inclusion, Accessibility, and Belonging to ensure that advances in EO benefit the widest possible range of stakeholders. We explore strategies for co-producing messages with communities, designing accessible visuals, and using culturally informed storytelling to bridge the gap between scientific innovation and lived experience.

By the end of the tutorial, participants will be prepared to communicate research in a way that matches the urgency and complexity of the future EO landscape. They will leave with transferrable strategies for amplifying the societal impact of their work and strengthening the global narrative around Earth observation and resilience.

Description

Natural catastrophes are becoming more often and intense due to climate change and human interference. Traditional approaches in disaster management predominantly struggle to offer timely and accurate real-time localized information in providing robust and rapid responses for disaster mitigation, especially in the complex inaccessible and impassable terrain regions. However, the remote sensing data has enabled users to map the disaster-prone areas more precisely and repetitively. The accessibility and availability of remote sensing data and their integration with Geospatial Artificial Intelligence (GeoAI) technology and cloud-based platform have accelerated the non-structural based disaster management approach. Unconventional technology such as GeoAI and cloud-based remote sensing allows easy and rapid development of tools having capability of automation, scalability, affordability, wider applicability at minimum computational facility, user-friendliness, diverse applications, high market demand, and substantial job returns than conventional technologies. The remote sensing derived attributes of disaster events are also required as input in conventional process-based models. Hence, it has been more pressing to acquire integrated knowledge and skills related to GeoAI, and cloud-based remote sensing computation for developing the improved and robust disaster management strategies.

The proposed tutorial will provide lectures and hands on experience to the IGARSS25 participants related to applications of advanced unconventional techniques for improved disaster management. The tutorial will leverage the potential use of unconventional technology such as GeoAI in conjunction with cloud-based platform, particularly Google Earth Engine (GEE) for real-time application of remote sensing in disaster management. The proposed tutorial will cover the end-to-end workflow from data acquisition such as Synthetic Aperture Radar (SAR) to integrated application of unconventional technology for real-time mapping and monitoring of disasters particularly floods including riverine, urban, and Glacial Lake Outburst Floods (GLOFs). The insights gained during this tutorial will enable the participants to develop and customize the automated applications and tools, scalable in nature for their unique research and wider application needs in regional disaster resilience and risk mitigation, particularly floods.

The IGARSS community includes the large number of crowds having immense research interests in the field of emerging unconventional technology such as GeoAI, and cloud-based remote sensing application in disaster management. And the interests and applications of these technologies are increasing rapidly due to their many appealing characteristics. Hence, the proposed tutorial is framed to keep the present requirements of the IGARSS community participants and will draw interest from multiple cores and applied disciplines. The proposed tutorial perfectly aligns with the goal of IGARSS to foster advancement in remote sensing and geospatial field for worldwide benefits. The tutorial addresses the combined application of this unconventional technology in disaster management which is more appealing to researchers and practitioners in hydrology, climate science, urban planning, and environmental monitoring. At the end, attendees will acquire insights and skills in integrated application of cutting-edge unconventional technologies such as GeoAI, cloud-based remote sensing which will build and enhance their capabilities in scientific understanding and development of strategies for preparedness, response, and disaster resilience-building, particularly for floods within their communities and globally.

Description

This tutorial provides an advanced yet accessible overview of machine learning strategies for integrating optical and SAR data in Earth observation, emphasizing both the foundations of data understanding and the latest multimodal learning techniques. Participants will learn how to prepare, align, and combine these two complementary modalities to enhance environmental monitoring, change detection, and semantic mapping.

We begin by revisiting the fundamental properties and complementarities of optical and SAR data. Participants will gain an intuitive understanding of their physical principles - spectral reflectance versus microwave backscatter - and how imaging geometry, resolution, and environmental conditions affect information content. This section introduces key pre-processing steps required for data harmonization, including radiometric and atmospheric correction for optical imagery and calibration, terrain correction, and speckle filtering for SAR data. Practical demonstrations will illustrate how to co-register and align Sentinel-1 and Sentinel-2 products to build consistent multimodal datasets.

Building on these foundations, the tutorial transitions to the machine learning perspective, addressing challenges such as domain discrepancy, scale differences, and feature alignment. We explore how recent multimodal deep learning paradigms—including cross-modal pretraining, knowledge distillation, and contrastive self-supervised learning—enable networks to leverage correlations between sensors and learn shared representations.

Participants will be introduced to practical examples of inter-modality learning, where optical data acts as a supervisory or guiding signal for SAR-based models:

  1. Transcoding-based pretraining: adapting networks pre-trained on optical data for SAR tasks.
  2. Knowledge distillation: transferring semantic understanding from optical to SAR networks.
  3. Multimodal self-supervised learning: using paired Sentinel-1/Sentinel-2 data in DINO- or CLIP-like frameworks.

Hands-on sessions will guide participants through real workflows:

  1. Exploring and visualizing Sentinel-1 and Sentinel-2 data in common analysis platforms.
  2. Performing basic co-registration and data alignment to prepare multimodal datasets.
  3. Extracting complementary features from SAR and optical imagery for joint analysis.
  4. Training and evaluating machine learning models for land cover mapping or flood detection using combined data.

Finally, case studies in environmental monitoring, disaster response, and land cover mapping will demonstrate how combining optical and SAR data increases accuracy and robustness under real-world constraints such as cloud cover or limited labels.

By combining theoretical insights with practical exercises, this tutorial offers a comprehensive pathway from data preparation to multimodal learning, showing how sensor synergies reshape our ability to extract meaningful geophysical information from satellite observations.

Description

The exponential growth of data and computational power has unlocked new frontiers in research. This evolution is increasingly powered by Large Language Models (LLMs), which have moved beyond text generation to become sophisticated reasoning engines. This has initiated a paradigm shift toward agentic workflows, where LLMs and other computational tools are orchestrated as autonomous or semi-autonomous agents to tackle complex, multi-step problems. When applied to scientific inquiry, this approach facilitates automating hypothesis generation, data analysis, and insight extraction. However, unique challenges persist in applying these agentic systems to specialized domains like Earth Observation (EO), particularly in grounding LLMs, reasoning with geospatial datasets, and ensuring the reliability of autonomous systems. This tutorial addresses these challenges by guiding participants through the lifecycle of designing, and implementing agentic workflows for scientific discovery using a new framework called Accelerated Knowledge Discovery (AKD).

Tutorial Learning Objectives

Participants will gain understanding of the foundational principles of LLMs and the architecture of agentic workflows. This tutorial will cover key aspects of building robust agents for scientific applications, starting with hands-on training in prompting for science, understanding Agent Protocols, and moving to the design of complex, multi-agent systems as well as multi-faceted evaluation of the underlying processes to conform to the rigorous expectations set forth by the domain. Participants will acquire skills to use agentic workflows effectively to accelerate their research. They will explore implementing these workflows, and learning to connect LLMs to external data sources and tools for a specific Earth Science use case. Participants will work directly with the AKD framework to design and implement a multi-agent workflow tailored for an Earth Observation system. They will also gain insights into the complexity involved in evaluation of the agents - with hands-on sessions of end-to-end evaluation process for the agents. Compute and Model access will be provided. To maximize hands-on time, course organizers will pre-configure resources, preventing setup delays. This will enable participants to navigate the complete lifecycle of an agentic project—from initial design to a functional system for scientific discovery.

Prerequisites

Participants should have a good conceptual understanding of Large Language Models (LLMs). Experience in Python programming is required, including proficiency in foundational data science libraries such as Numpy and Pandas. Familiarity with deep learning frameworks like Langchain, Langgraph, as well as experience with API integrations is highly beneficial, but not required. Each participant should bring a laptop (Windows, Mac, or Linux).
