Knowledge and skills for using remote sensing products as a source of geodata on current and historical landscape conditions for geographical spatial analyses.

In this seminar, students learn about the possibilities and specifics of evaluating aerial and satellite images. The acquisition of image data is discussed as well as procedures and techniques for their systematic GIS-based evaluation.

    The following topics are covered:

    Three-dimensional aerial image evaluation

    Stereo vision

    Stereo techniques

    Image processing

Electromagnetic spectrum

    Main spectral ranges

    Radiation processes in the atmosphere

    Reflection behaviour

Imaging systems

Methods of systematic image interpretation

    Digitising in the 3D model

    False colour composites

    Land use mapping

    Evaluation key

    Multispectral analysis

    Image classification

(image measurement/photogrammetry)

    Central perspective

    Single image method

    Stereo image measurement

Weekly meetings with

    Presentations

    Exercises

    Tasks

Building on the basics from the GIS exercises, students learn in this practical software seminar how to work with raster data and how to use advanced analysis tools in ArcGIS (especially Spatial Analyst). The development of automated processes (Model Builder) for processing and interpreting geographical questions is in the foreground. Another fundamental component in this context is the understanding of technical processes and their results.

• Carrying out spatial investigations on the basis of raster and vector data

  Site evaluation according to suitability analyses

  Route planning with the help of cost-distance analyses

  Hydrological investigations (determination of catchment areas and watersheds)

  Generation of data by interpolation (Natural Neighbour, Spline, IDW, Triangulation)

  Automation of processes with the Model Builder

  Further contents possible depending on the course

The focus of the course is on teaching the theoretical basics of thematic cartography. With the help of the module, the students should become familiar with the projection basics, drawing-theoretical prerequisites and typical construction processes of modern cartography through small exercise units. This should lay the foundations for the independent generation of thematic cartographic forms of presentation. An elaboration of cartography software accompanied by exercises introduces the practical creation of maps.

Aims of thematic cartography

- Construction of network designs

- Cartographic representation methods (basic models); modelling in cartography

- Thematic cartographic visualisations

- Process of map construction

- Introduction to cartographic software

- Project work

The course covers three phases:

a) Cartographic basics - projection theory

b) Thematic cartographic basics,

c) Introduction to cartography software

In many geographical professions, working with geodata is not limited to the use of geoinformation systems in the office. Numerous fields of work - for example in agriculture, biotope and nature conservation, cadastral administration or infrastructure management - also involve work in the field, the success of which depends on the precise collection of up-to-date field data. At the same time, on-site access to existing data is often crucial.

Due to the increasing availability of (free) geodata and the rapid technical progress in hardware and software, there are now possible solutions for practically every application that allow efficient networking of office and field work in real time.

The aim of the seminar is to provide a first introduction to the world of mobile GIS and to give an overview of the basic possibilities. Various aspects of the use, collection or distribution of geodata for field work are to be examined by the students in the form of a presentation and finally tested on the basis of their own exemplary field work.

Overview of a selection of relevant basics and software solutions for the mobile handling of geodata, e.g....

    Free geodata: Open Street Map

    Free geodata: Official geodata

    Satellite positioning (GNSS)

    Cloud and server technologies for geodata - Linking indoor and outdoor areas

    Project planning for field work (e.g. campaign planning, routing)

    Software solutions for mobile geodata collection (e.g. ArcGIS Collector, M.Apps. QField)

    Web apps for mobile geodata collection (e.g. OpenLayers, Leaflet, Mapbender)

    User Generated Content / Volunteered Geographic Information

    Conception and implementation of an exemplary field work using the techniques learned.

Further contents are possible depending on the course.

- Promoting the competent use of modern geodata resources (geodata literacy).

- Expanding knowledge of current developments in geodata and geodata infrastructures (especially EU, federal government, federal states, municipalities, OpenStreetMap)

- Familiarisation with and application of basic concepts of advanced geodata analysis with Geographic Information Systems (Open Source GIS: QGIS)

- Learn and apply basic concepts for the cartographic presentation of geodata.

The increasing availability of open geodata poses the challenge to geographers to critically evaluate corresponding geodata resources (geodata literacy) in order to research suitable (input) data to answer analytical questions. These data can be processed with a variety of analysis and visualisation tools in different geographic information systems and other web cartographic applications. This course focuses on the development of geodata literacy skills and the application of suitable and advanced analysis and visualisation tools. Open geodata and open source processing applications form the methodological basis.
