Course content

The course is divided into two parts. The first part focuses on the fundamentals of photogrammetry, with special emphasis on drone-based mapping systems and the production of elevation models and orthophotos. Part two provides an overview of Norwegian spatial datasets available on the Geonorge portal (standards, product specifications, metadata), with particular emphasis on datasets relevant to the construction industry.

Themes:

• Electromagnetic radiation
• Digital images and photography
• Stereo photogrammetry
• Aerial triangulation. Error sources and quality control
• Point cloud, DTM and DSM production. Error sources, quality control, and applications
• Orthophoto production. Error sources, quality control, and applications
• sUAS-based topographic mapping systems
• Norge digitalt and Geovekst
• Geonorge portal
• Norwegian datasets with emphasize on FKB
• Geographical information systems

Learning outcome

By the end of the semester students will:

• have basic knowledge of the principles of airborne photogrammetry.
• have the necessary knowledge to describe the quality and practical applications of mapping data derived from airborne photogrammetry.
• be able to apply techniques to process stereo photogrammetry and aerial triangulation, including understanding error sources and quality control procedures.
• be able to create mapping products from sUAS-based photogrammetry, such as 3D point clouds, digital terrain models, contour lines, and orthophotos.
• have sufficient knowledge to perform quality control and assessment of mapping products generated from sUAS-based missions.
• be able to explain the potential error sources and control measures in point cloud, DTM/DSM production, and orthophoto generation.
• have basic knowledge of how geodata production is organized i Norway (Norge digitalt and Geovekst).
• be able to download and use data from Norge-digitalt in a geographical information system.
• have sufficient knowledge to understand product specifications and metadata with emphasize on basic geodata og planning data.
• have basic knowledge of quality in geographical data relevant to the building industry.
• know the delivery requirements for geographical data in Geovekst projects.
