Digital Terrain Analysis

GEOG60412 Digital Terrain Analysis 15 Semester 2 Postgraduate Taught Level 6 Anna Hughes Unit coordinator 1 FHEQ level (Framework for Higher Education Qualifications) ' Masters/Integrated Masters P4 ' European Credit Transfer & Accumulation System Rating : 7.5 This course will introduce students to the principles and applications of GIS for analysis of 3D data, focussing on approaches to digital terrain analysis and geomorphometry. The focus will be on the principles, acquisition, and processing of digital elevation models from topographic data collected using active and passive remote sensing methods, including from LiDAR and Structure-from-Motion via small unscrewed aerial systems. Examples will predominantly draw from applications in glaciology and glacial geomorphology, but techniques covered are relevant to a wide range of applications across physical geography, geology and environmental science.

The unit aims to:To equip students with necessary knowledge and skills to use digital terrain data for landscape analysis, and gain experience of the collection, handling and manipulation of 3D spatial data. <ul><li>Students can expect to develop broader academic skills including academic literature search, reading and critical analysis via assignment 1.</li><li>Second assignment encourages students to develop their project management and research design skills by developing a mini-research project that requires sourcing, manipulation and handling of elevation data. This also gives practical experience of working with this data on a problem of their choosing.</li><li>Unit inherently develops digital literacy as is focussed on working with and understanding 3D digital data in a GIS. E.g. Guided computer practicals give experience of working with a variety of data types and formats. Producing visualisations of spatial data for reports and poster presentation.</li><li>Assessment is set up to facilitate in-class and online engagement; e.g. online poster discussions via Padlet. Navigating/accessing/identifying learning materials via the VLE.</li><li>Students also required to use appropriate search engines/indexes/databases to find information. Manage and retrieve information for study ie (bookmarks/referencing software).</li></ul> <ul><li>Understand a range of digital elevation data types, collection methods and processing techniques. </li><li>Gain knowledge of the use, strengths, and limitations of 3D spatial data. </li></ul> <ul><li>Critically evaluate topographic data types, processing techniques, and approaches to 3D data visualisation.</li></ul> <ul><li>Source, manage and handle digital topographic data from a range of sources in appropriate GIS software.</li><li>Use GIS software to visualise 3D data.</li></ul> <ul><li>Develop succinct written and visual communication skills.</li><li>Ability to source and process 3D spatial data to explore research questions using digital terrain analysis and geomorphometry.</li></ul> Syllabus (indicative curriculum content):An introduction to the principles and applications of GIS and 3D elevation data, focussing on approaches to digital terrain analysis and geomorphometry. The focus will be on the principles, acquisition, and processing of digital elevation models from topographic data collected using active and passive remote sensing methods, including from LiDAR and Structure-from-Motion via small unscrewed aerial systems. Case studies and examples will predominantly draw from applications in glaciology and glacial geomorphology, but techniques covered are relevant to a wide range of applications across physical geography, geology and environmental science. Lectures supported by computer labs on the generation and processing of digital elevation data using GIS and remote sensing software (e.g. ArcGIS Pro, QGIS, Agisoft Metashape, Drone2Map). Independent learning via reading outside of lectures. Application of learning via a mini-research project.The unit runs over one semester, consisting of lectures, guided-computer practical exercises, and project surgeries. Students are expected to supplement the knowledge gained in lectures and practicals with their own reading and independent study. Practical worksheets will provide experience of data processing techniques and give students opportunity to seek clarification with teaching staff. Students will undertake an individual project using topographic data, which forms the main summative assessment via a poster presentation to assess data visualisation techniques from the course and production of derived data. Project results will be shared and discussed during a group poster presentation at the end of the course. 3 Report 40% 6 Project output (not diss/n) 60% Formative Assessment Task 1 Short-answer questions associated with guided computer practical sessions. 500 words max equivalent. Expectation that practicals are mostly completed within class-time (2 hours). (Indicative <50-100 words per worksheet). Verbal feedback during practical sessions.
