Semester 1 | Geographic information systems and remote sensing | Examination conditions T3120 – Geographic information systems and remote sensing Examination conditions I Learning Outcome Upon successful completion of the course, students will know how to translate tasks into projects and thematic maps in GIS, how to use GIS software and different datasets to visualize spatial and temporal relationships in projects, and how to later use maps and spatio-temporal data as a tool to communicate within projects. II Exam type The task for this module is to produce a themed map that explains the project area and displays the results of spatial analyses in different subject areas. This requires creating a GIS project and docu- menting its production in line with the accompanying template chapters. The project documentation should be brief and succinct. Please structure the GIS project according to the documentation to en- sure others can understand and reuse it. Use the basics taught in the map creation lecture to create a thematic map and generate a printable PDF in A0 format as the end product. III Assessment criteria Your examination performance is assessed based on 12 assessment criteria. These criteria are di- vided into four areas: "Collect data for the study area", "Spatial analysis of the sub area", "thematic map creation" and "presentation of results". The results in “Collect data for the study area” and “presentation of results” can be a team performance result. The evaluation criteria are explained in more detail in the appendix "Evaluation form" and "Documentation template".
