Course content

This course prepares for the field course 'Desertification' (51329DEL6Y, Semester 2, period 5) with a fieldwork in Southeast Spain (Murcia) near Lorca, in April. During the Digital Earth (DE) course students collect, organize, process, analyze and visualize environmental datasets which will be used in the ‘Desertification’ course.

The topics to be covered in DE include:

• Preparation of a geodatabase in ArcGIS Pro.
• Digitalization and classification of Land Use / Land Cover (LULC), through analysis of high resolution satellite-, ortho-photo and drone imagery.
• Calculating a Digital Elevation Model (DEM) from a contour line dataset and extracting selected Land Surface Parameters such as slope gradient and aspect and creating related maps.
• Application of geospatial analysis techniques to find relations between environmental information layers.
• Apply cartographic design / (3D) visualization and printing of maps for use during the Spain fieldwork.
• Writing a technical GIS report in which the geodatabase design, the geospatial datasets, the methods used and the output results are presented.
• Prepare print-ready pdf field maps in the correct scale and layout.
  3 maps without digitizing, but with correct scale, clipping to the correct extent (3 strips) and correct cartographic layout: Topographic Map, Geological Map and Soil Map.
  3 maps made with the help of digitizing objects (points, lines, polygons): Geomorphological Map, Land Use Map and Hydrological Map.

Study materials

Software

• ESRI ArcGIS Pro 3.3 or higher on WINDOWS laptop or WINDOWS computer, NOT on Apple devices

• ESRI Field Maps (on smartphone)

• Google Earth (on laptop or computer)

Other

• GIS related apps on smartphone such as digital compass, offline maps, etc. might come in handy

Objectives

• The student can prepare geospatial information layers relevant for fieldwork by integrating existing thematic information and newly prepared data layers into a GIS geodatabase and into Google Earth Pro.
• The student can digitize concept geomorphological, land use and hydrological maps and add relevant attribute information based on remote sensing imagery and surface pattern analyse.
• The student uses remote sensing & geospatial analysis tools and theory and can analyze remote sensing imagery, with emphasis on the Spain fieldwork area.
• The student can create a technical GIS-report in which the workflow used, the geospatial metadata, the used methods, and the deliverables of the fieldwork area are presented and described.

Teaching methods

• Lecture
• Computer lab session/practical training
• Self-study
• Working independently on e.g. a project or thesis

Four lectures on Southeast Spain. Five self-tuition assignments. In total ten laptop practicals, of which the last 5 are targeted on the Spain geodatabase project, done in small groups of 4 students. Writing a GIS project report with the group members. Prepare pdf maps in this course and print them in next course, before going on fieldwork to Spain.

Learning activities

Attendance

Programme's requirements concerning attendance (OER-B):

• Participation in fieldwork is compulsory and cannot be replaced by assignments or other courses.
• In case of practical sessions, the student is obliged to attend at least of 90% of the sessions and to prepare himself adequately, unless indicated otherwise in the course manual. In case the student attends less than 90%, the practical sessions should be redone entirely.
• In case of tutorials/seminars with assignments, the student is obliged to attend at least 7 out of 8 seminars and to prepare thoroughly for these meetings, unless indicated otherwise in the course manual. If the course has more than 8 seminars, the student can miss up to 1 extra meeting for every (part of) 8 tutorials/seminars. If the students attends less than the mandatory tutorials/seminars, the course cannot be completed.

Additional requirements for this course:

In case of the 10 laptop practical sessions, the student is obliged to attend at least 90% of the first 8 sessions and to prepare him/herself adequately, unless indicated otherwise in the course manual. In case the student attends less than 90%, the practical sessions should be redone entirely. In other words: a student is allowed to miss at most 1 out of the first 8  laptop practicals. The 2 laptop practicals in the last week of the course (week 10, 2025) are not obligatory and may be missed (you are supposed to work on the assignments until they are done), but you are invited to join and get assistence on the spot. 

The first lecture/werkcollege (de Boer) at Science Park, on Monday, February 3rd 2025, is obligatory!
Attendance at the other three lectures is strongly recommended! Each lecture prepares for the theme of that week. Hoorcollege (lecture), first and second laptop practical in each week in the first 4 weeks of the course form a thematical unit.
The lectures (hoorcolleges) are NOT recorded, as they prepare for the laptop practicals of that week, not for an examination.
So you have to be present in the lecture hall at Science Park in person.

For tutorials ('practicals') there is a strict attendance rule: The first 8 laptopcolleges are mandatory (see above). Of those 8 you are allowed to miss 1. After that, the 2 laptop practicals in the last week of the course (week 10, 2025) are not mandatory.

If you’re attendance at practicals is not substantial (if you miss more than allowed) your course will be graded with NAV. This results in a NAV for the whole course.

Absence needs to be communicated in advance to the course coordinator.

In Datanose the whole cohort in this course is divided into a 'group A' and a 'group B'. Switching between those groups is only limited possible, in the first week, in making the fieldworkgroups of 4 students. We have this year the luck of having only two parallel sessions in the two groups. In previous years the puzzle about all fieldwork groups, study variants, subjects, rooms and availability of teachers & assistants was too complex to facilitate switching. This year the switching is limited in the sense that the two groups A and B should not differ too much in size.

Last year's student feedback

In order to provide students some insight how we use the feedback of student evaluations to enhance the quality of education, we decided to include the table below in all course guides.

Course Name: Digital Earth (3 EC) (course 2023-2024)	N > 66 %	7.6 (10 point scale)
Strengths Overall assessment was fairly good;  80% of the students is '(very) satisfied' with the practical application Practical work with ArcGIS, variety of assignments, good assistance, introduction to fieldwork. Clear course design, high academic challenge, student-activating teaching, high level, good study material.	Notes for improvement The requirements set for the report were not clear to everybody. More clarity on what deliverables are expected. Make clear to students that this course is first of all about learning GIS skills, by 'learning by doing'. Not everything has to be perfect or will succeed at once, because of practical issues. Students would like to be able to assess their peers on the basis of their contribution to the project. Results e.g. answers to the questions in the 5 core Canvas Quizzes should be available after one week or so. Workflows, now spread over the 5 modules should also be available in one central document (pdf) as a lookup source for repeating workflows.
Response lecturer: Last year, the course Digital Earth was running smooth, because a lot of issues are resolved in the past few years. For instance dataset delivery (now via Canvas), projection (1 unified projection), working with the 64 bit application ArcGIS Pro (more stable) and project package files. The spread in grades last year was good; there were no insufficients. Last two years, much of the previous 'Project Spain' assignments are integrated into the Canvas Modules 1 - 5 and into Canvas Workflows. So there is more step-by-step teaching and the Project Spain starts earlier with more time for digitizing. In the Canvas Quizzes the deliverables are explained much better and uploads of them are more facilitated. The concept of 'Virtual Fieldwork' (introduced online in the corona years) is integrated much more in the course last two years. New drone images (made in 2019, 2021, 2022 and 2023) of the fieldwork area in Spain make this possible.
