3D Reconstruction from Multi-View Satellite Imagery: From Classic to Modern Methods

Full Day (8 Hours)

High-resolution (high-res) satellite images, which can now observe the Earth with a footprint as small as 30 cm (e.g., WorldView-3/4 sensors), play an important role in generating 3D data over wide areas. Due to orbital limitations, these images have unique characteristics, and their photogrammetric processing requires special considerations. This tutorial is intended for beginners and intermediate users, including students, researchers, and practitioners interested in 3D mapping with multi-stereo satellite images and their applications. Participants will gain hands-on experience with relevant software and learn about recent developments in field-based methods for 3D reconstruction using satellite imagery, including 3D Gaussian Splatting and Neural Radiance Fields (NeRF). The tutorial will cover both theoretical and practical aspects of processing multi-view satellite images and will be divided into a theory session and a hands-on practical session. The theory session will cover: – Existing satellite sensors – Camera models (rational polynomial models) – Bundle adjustment – Surface generation – Orthophoto rectification – Emerging techniques like Neural Radiance Field (NeRF) and 3D Gaussian Splatting (3DGS) In the practical sessions, we will demonstrate: -Satellite imagery selection – Level-1 geometric correction – Pan-sharpening – Relative and absolute orientation – Dense matching using the RPC stereo processor (RSP) to generate colored point clouds, digital surface models (raster and textured meshes), and true-orthophotos. – Examples of NeRF & 3DGS to generate a DSM, shadow mask, and albedo (shadow-free) maps.

Quantum Computing for Earth Observation

Full Day (8 Hours)

Classical high-performance computing has long supported remote sensing and Earth observation activities. However, as data volumes and modeling complexity continue to grow, classical computational approaches are becoming increasingly strained. This trend motivates the exploration of emerging computing paradigms. One promising direction is quantum computing, which leverages quantum mechanical principles such as superposition, entanglement, and interference to perform certain computations more efficiently than classical systems.

With this in mind, this tutorial offers a practical introduction to quantum computing, with a focus on quantum machine learning. Participants will have the opportunity to implement a quantum machine learning algorithm for a real-world application in multispectral satellite image analysis. Basic knowledge of linear algebra and Python programming is required to participate in this tutorial.

The tutorial will begin with an accessible introduction to the principles of quantum computing. A representative problem based on satellite imagery will then be defined, and the tutorial will alternate between conceptual discussions and hands-on implementation, including gate-based quantum circuit design. As the session progresses, the interplay between quantum and classical resources will be explored across the full processing pipeline. Simulated implementation of a quantum system will be introduced, and with the support of PINQ², access to real quantum platforms of IBM will be made possible as well.

By the end of the tutorial, participants will gain a foundational understanding of quantum computing and its practical applications in remote sensing.

Web-Based Campus Routing and Event Management System

Full Day (8 Hours)

Many universities offer web-based campus maps with a wide range of features, from 3D maps to indoor navigation tools. However, implementation of commonly desired features — such as geolocating entities, routing between them, and displaying campus events — are often outsourced to external providers, which undermines the sustainability and maintainability of these systems.

This tutorial introduces an open system called ROAMer — Reproducible OSRM for Mapping and Event Reporting — which leverages a suite of open technologies, including (but not limited to) Open Source Routing Machine (OSRM), PostgreSQL/PostGIS, React, and Node.js.

This tutorial will provide participants with hands-on experience in replicating a web-based GIS tailored to their own university campuses on their local machines. All technologies introduced in this tutorial are open source, demonstrating that such a system is both sustainable and maintainable within the university context, without requiring software licensing fees or reliance on proprietary services.

By the end of the tutorial, participants will gain an understanding of the key concepts behind web-based GIS design and development using a relational database management approach and will be able to apply these concepts to implement a functional, customizable campus GIS for their own institutions.

Uncertainty-aware Bayesian Neural Networks

Half Day (4 Hours)

Conventional AI and machine learning models often function as black boxes, offering predictions without indicating their confidence or reliability. In contrast, uncertainty-aware models provide insights into how much trust can be placed in each prediction. This is especially critical in remote sensing, where decisions frequently depend on model outputs under conditions of data sparsity and noise.

This tutorial will equip participants with both theoretical foundations and practical skills to implement Bayesian Neural Networks (BNNs) that disentangle aleatoric (data) and epistemic (model) uncertainty. The session will cover the fundamentals of uncertainty, Bayesian approaches to predictive distributions, and include hands-on coding exercises using Python and TensorFlow on remote sensing datasets for tasks such as land cover classification.

This tutorial is intended for researchers, graduate students, and practitioners with basic machine learning and Python experience who seek to enhance the reliability and transparency of their remote sensing models.

By the end of the tutorial, participants will learn to implement, visualize, and interpret uncertainty within BNN workflows to better identify sources of error and refine data collection strategies. They will also learn how to build robust, interpretable, and uncertainty-aware models for Earth observation and environmental modeling.
