Remote Sensing and Digital Image Processing

The course focuses on up-to-date knowledge and technology in the field of photogrammetry, Remote Sensing (RS) and digital image processing for geo-information extraction and production.

In this course, you will learn the theoretical concepts and practical skills to extract geoinformation in established upcoming techniques and innovative approaches. Besides, you will understand the connection of the acquisition and processing procedures, with the accuracy of the results and its relevancy for various applications. 

Managing land use and the Earth’s resources and facing global challenges is becoming increasingly important due to the rising world population, economic growth, environmental degradation, and climate change, among others. 

The use of available, up-to-date, accurate and well-structured geoinformation is essential for applying various applications and utilizing the data to face global challenges and reach the optimal solutions. Thus,  planners, resources managers and application scientists now make considerable use of frequently acquired high and medium resolutions of multispectral images and other data structure such as 3D point clouds. Multispectral images are captured from various spaceborne and airborne sensors, as well as innovative platforms such as drones, 3D point clouds can be acquired with modern techniques such as laser scanner. 

Thus, it is essential to train the staff to extract both thematic and 3D geoinformation from different sensors or scanners in automated and semi-automated processing environments which are continuously under development. 

 For whom is the course relevant?

  • Staff from government agencies and private companies who have practical professional experience in remote sensing and/or photogrammetry and who wish to become familiar with state-of-the-art knowledge and technology. 
  • GIS specialists who make regular use of digitally acquired spatial reference data and are interested in the source and accuracy of these data. 
  • Staff and researchers from non-geo disciplines, who want to employ geoinformation in their research or work would also significantly benefit from this course.

What is the course content?

The course is structured in 4 sequential modules of 3 weeks each. The first two modules are concentrated on Remote sensing topics and the last two on photogrammetric topics. Learning outcomes are defined per module and evaluated progressively at the end of each one.

  • Module 1: Digital Image Processing

    In this module, you will understand and apply the basic radiometric preprocessing like atmospheric calibration, spatial and temporal filtering and contrast enhancement operations, which is essential in a geospatial problem-solving process. Besides, you will explore the integration of spectral bands in indices and ratios to provide sufficient insight into the information contents of the multi and hyperspectral data sets. 

  • Module 2: Advanced Image Classification

    In this module, Random Forests (RF) classifier will be taught and used to classify both single-date and multi-temporal satellite images. Various strategies for generating samples required to train supervised machine learning classifiers and assess their classification results will be explained in detail.

  • Module 3: Earth Observation Sensors for Mapping Applications

    In this module, you will have a  general overview of the EO sensors. The course will also treat in more focus the new platforms and sensors relevant to large-scale mapping applications such as  Unmanned Aerial Vehicles (UAVs), the aerial oblique digital sensors, and laser scanners. Besides, you will apply Global Navigation Satellite Systems (GNSS) receivers to measure the point coordinates and assess the quality of the results. 

  • Module 4: 3D Data Acquisition from Aerial Imagery

    In this module,  you will learn the geospatial data processing techniques to derive 3D geoinformation from a sequence of overlapping aerial images. Mixing between the digital photogrammetry methods and the advanced methods will be presented. The innovative techniques will be demonstrated using images acquired by a drone. A hands-on experience will be gained using the appropriate software packages to process different data sets: aerial and drone images.

What will be achieved?

Upon completion of the RS modules, you will be able to: 

  • Select appropriate sensors and image data for geospatial problem solving
  • Apply relevant contrast enhancement for visual and digital image analysis
  • Apply spatial and temporal filters to improve image data for visual and digital image analysis
  • Calculate indices and ratios for digital image analysis
  • Apply different strategies for generating training and validation samples for supervised machine learning classifiers
  • Apply various feature selection methods for data dimensionality reduction purposes
  • Summarize the main multi-temporal image analysis steps
  • Apply Random Forest classifier to classify both single-date and multi-temporal images
  • Critically interpret the classification results obtained by applying supervised machine learning classifiers
