Introduction to Geomatics
Dieses Modul führt in die Geomatik, in Theorie und Anwendung von geo(infor)matischen Methoden ein. Es fasst die komplementä-
ren und für die Geographenausbildung zentralen methodischen Grundlagen, der Arbeit mit geographischen Informationssystemen
(GIS), Kartographie (KART) und der Fernerkundung (FE) zusammen. Es geht dabei um die Erfassung, Analyse, Modellierung und
Visualisierung raumbezogener Informationen. Dabei beschäftigt sich die FE mit der Erfassung und Auswertung von Informationen
über raumzeitliche Prozesse und Strukturen mit flugzeug- und satellitengestützten Sensorssystemen. GIS dient der Analyse und
Modellierung räumlicher Strukturen, Muster und Prozesse. Die Kartographie wird in der Vorlesung unter zwei Aspekten angespro-
chen: einmal als räumliches Bezugssystem von Geodaten und zweitens als ein Methodenbaukasten zur Visualisierung von Daten
mit Raumbezug. In diesem Modul erwerben Sie die erforderlichen theoretischen, methodischen und praktischen Grundlagen, um
mit Geodaten zu arbeiten, diese fachlich kompetent zu interpretieren, zu analysieren und mittels verschiedener Softwarepaketen
die Kenntnisse praktisch anzuwenden.
Die Vorlesung besteht aus zwei parallelen Teilen mit gemeinsamen Übungen. Im ersten Teil werden die Kenntnisse zu GIS und
Kartographie vermittelt, im zweiten die zur Fernerkundung. Die Teilnehmenden bilden Arbeitsgruppen, die Übungsaufgaben ab-
wechselnd aus den Bereichen GIS/Kartographie und Fernerkundung bearbeiten. Dabei werden sie durch die Tutor*innen der Stu-
dierendenwerkstatt Geomatik unterstützt.
Die Klausuren werden voraussichtlich im folgenden Zeitraum geschrieben werden:
1. Termin: 17.-21.02.2025
2. Termin: 17.-21.03.2025
Die Einsicht zu den Klausuren wird am 3. März 2025 und am 31. März 2025 stattfinden.
Bitte beachten Sie, dass die genauen Daten innerhalb der Vorlesung bekannt gegeben werden und diese dann verbindlich sind.
Modelling Terrestrial Ecosystems Using Spectral Remote Sensing
Course motivation and content:
In the Anthropocene era, impacted by a man-caused global warming due to excessive CO2 emissions, computer models simulating and forecasting temporally dynamic eco-physiological processes of terrestrial vegetation, such as carbon uptake or evapotranspiration, are essential for a ‘carbon neutral’ economy and a ‘carbon reducing’ management of natural ecosystems. Optical remote sensing provides multitude of input data for dynamic land surface vegetation modelling, spanning from categorical maps of land cover classes to spatially explicit quantitative estimates of vegetation biochemical and physical traits such as: fraction of absorbed photosynthetic radiation, leaf area index, or contents of water, photosynthetic foliar pigments, and nitrogen. This remotely sensed information, retrieved from air-/space-borne spectral and thermal sensors, is getting more accurate and more frequent thanks to the improving sensing technology (e.g., hyperspectral imaging spectroscopy), a higher number of satellite constellations (e.g., new Sentinel and future Chime ESA satellites), and newly available optical signals like, for instance, sun-induced chlorophyll fluorescence (retrievable from NASA’s OCO-2/3 and ESA’s TROPOMI and future FLEX missions). This course is designed to enlarge knowledge and deepen understanding of M.Sc. students about actual and near future optical vegetation remote sensing products that can be assimilated by existing eco-physiologically based land surface vegetation models, such as ORCHIDEE, JULES or LPJ-GUESS. The knowledge gained in this course is essential for future study climate change related topics and useful for work in fields of precision agriculture, forest monitoring and natural ecosystems’ management.
Course structure:
To comprehend advanced approaches for quantitative estimations of vegetation traits from Earth observations, the course participants will learn how the solar electromagnetic radiation interacts with individual plant leaves and canopies, what are the main pre-processing and remote sensing image interpretation methods, and how are the obtain maps of vegetation traits assimilated by the land surface vegetation models.
The seminar will be split into three thematic parts:
- Remote sensing observations: Acquisition, calibration, and pre-processing of leaf and canopy spectral measurements data.
- Interpretation methods: Methods for retrieval of vegetation traits from satellite spectral measurements.
- Dynamic vegetation models: Assimilation of remote sensing products in selected land surface vegetation models.
The seminar will contain theoretical lectures (45-min per week) delivered by the lecturer and computer-based practical exercises (for instance, spectroscopy of vegetation leaves and canopies) performed by the course participants. A multiple-choice test will be carried out upon the completion of each thematic part. The final grade of each seminar participant will be deduced from correct answers of tests and computer exercises.
Course outcomes:
On successful completion of this module, students will be able to:
- Understand how optical remote sensing can inform models predicting vegetation functioning within the carbon and water cycles.
- Find and assess quality of remotely sensed maps of vegetation traits relevant for eco-physiological modelling.
- Use/assimilate vegetation remote sensing product in to the dynamic land surface vegetation models in order to predict, for instance, vegetation carbon assimilation capacity or water use efficiency.
Remote Sensing Methods for Wildfire Landcover Change Detection
In 2016 and 2019, Australia, especially the Tasmanian island, was subjected to some of the most widespread and devastating wildfires in recent history. What made these fires so devastating is the particularly ”dense bush” type of Australian vegetation that they affected. In 2016, large parts of the Tasmania World Heritage Area and the Arthur-Pieman Conservation Area were destroyed. These vegetation communities are unique and take thousands of years to regrow. Many affected areas are remote and largely inaccessible, making a ground assessment of the true scale of the fire devastation difficult, in some locations even impossible. In this Geomatic Method seminar, you will use multispectral remote sensing images of Sentinel-2A and Landsat-8 satellites to identify the extent of the wildfires within the Arthur-Pieman Conservation area and estimate the types and amounts of vegetation that were affected by the 2016 burn.
Participants will individually execute 12 assignment tasks. The tasks will be split into two parts:
- literature work (2 tasks), resulting in a short (400 words max.) essay describing theoretical bases of forest fire mapping from multispectral space-borne image data (written preferably in English), and
- computer work, comprised of 10 practical tasks and several questions about satellite image pre-processing methods (e.g., spatial and radiometric corrections), spectral analyses (e.g., automatic image classifications), and landcover change detection (e.g., basic statistics). The results will be submitted to the lecturer as a report, i.e., *.PDF or *.DOCX digital document written in English.
Each of the 2 x 45 min seminars will consist of:
- 15-minute theoretical introduction related to the assigned task and presented by the lecturer,
- 5-10-minutes of discussion about general issues and problems related to individual tasks, and
- about 65 minutes of individual hands-on computer work under the supervision of the lecturer.
The final mark will reflect the quality of the literature work delivered in form of an essay (30% of the overall mark) and the correctness of the satellite image analyses’ outputs and answers to questions given in the computer work part (70% of the overall mark).
On successful completion of this module, you will know how to:
- use scientific literature to search for and process relevant published information,
- apply satellite image processing techniques in the context of forest fire detection and bunt area assessment, and
- extract quantitative and thematic information from satellite multispectral imagery by means of image pre-processing, classification, and change detection techniques.
The professional remote sensing software ENVI will be used in this module for computer-based work. The basic functionality of this software, i.e., loading and displaying an image with different spectral band combinations, image composition contrast enhancement, plotting of spectral signatures, working with regions of interest (ROIs), application of required image analyses, and export of images and plots suitable for inclusion in your assignment report, will be explained during first seminar sessions. Previous knowledge about remote sensing image processing will be to your advantage.

To successfully complete this module, all participants (sorted in couples by lecturer) will be asked to prepare an introductory spoken presentation (10-15 min, no slides, no visual support) on the topic related to the excursion program. Assignment of the topics will be done by lecturers two weeks before the start of the excursion. The presentation will be delivered during the travel in-between the excursion destinations (exact timing will be given by lecturer). After the excursion, all participants will conduct a multiple-choice quiz (on-line via the eCampus learning platform), featuring questions directly related to the educational content of the excursion. The minimum score to successfully conclude the excursion is 50% (i.e., at least half correctly answered questions).
The communication language during the entire excursion is English (including the presentations delivered by students and the final quiz).
The whole travel will be carried out by bus with overnights in a hotel-like accommodation. Since we will visit indoor but also few outdoor destinations, participants are expected to be equipped for short hikes in nature with hiking shoes as well as proper rain and sun protection. The estimate of expected costs covering accommodation and travel expenses (without food) is around 600€.

Remote Sensing for Mapping Drought and Insect Outbreaks in Forest Ecosystems
Forests play a crucial role in preserving our planet, as they serve as carbon sinks, absorbing CO2 and regulating the climate. Due to climate change that has largely impacted the natural ecosystems on Earth, forests are more and more threatened, not only by frequent and severe wildfires and droughts, but also by the outbreaks of insect pests such as bark beetle. In past two decades, the European forests were subjected to some of the most widespread outbreaks of Norway Spruce bark beetles, causing substantial damage. Some of the affected areas are remote and hardly accessible, making a ground assessment of the outbreak impacts difficult. In this Geomatic Method seminar, you will use multispectral remote sensing images of Sentinel-2 and Landsat satellite missions to detect the occurrence and to assess the extent of the of the bark beetle infestations in the Harz Mountain region (Germany) during the last decade.
------------------------------------------------------------------------------------
Course expected outcomes:
Upon successful completion of this course, you will know how to:
search for publicly available satellite imagery in online repositories,
use scientific literature to search for and process relevant published information,
apply satellite image processing techniques in the context of forest bark beetle outbreak detection and infested area assessment, and
extract quantitative and thematic information from satellite multispectral imagery by means of image processing and change detection techniques.
Description:
Course content and structure:
Participants will individually execute several assignment tasks. The tasks will be split into two parts:
literature work, resulting in a short (400 words max.) essay describing theoretical bases of forest bark beetle outbreaks mapping from multispectral space-borne image data, and
computer exercises, comprised of several practical tasks and relevant questions about satellite image processing methods, spectral analyses, and change detection. Python programming language will be used to process the satellite data and apply the suitable image processing methods in order to conduct these tasks. The results will be submitted to the lecturer as a report (i.e., *.PDF or *.DOCX digital document written in English).
Each 2 x 45 min seminar will consist of:
15–20-minute theoretical introduction related to the assigned task and presented by the lecturer,
5-10-minute discussion about general issues and problems related to individual tasks, and
about 65 min of individual hands-on computer work under the supervision of the lecturer.
The final mark will reflect the quality of the literature work delivered in form of an essay (30% of the overall mark) and the correctness of the satellite image analyses’ outputs and answers to questions given in the computer work part (70% of the overall mark).
-----------------------------------------------------------------------------------
