This course has no specific requirements. Students should only have a basic knowledge of using general software such as Windows, Excel and Word.
Objectives and Contextualisation
1. Sytematic coverage of web technology for implementing spatial data infrastructures as well of the different types of servers of geospatial information web services (map servers, metadata, geoprocessing, etc.) based on the standards of geospatial information services from OGC and ISO (WMS, WMTS, WFS, WPS, etc.).
2. Knowledge of the main free and commercial software for creating, publishing and managing the different types of geospatial information web services.
Competences
- Apply programming methodologies and procedures, and those for implementation of geospatial applications for different types of platforms (desktop, web, mobile), using different programming paradigms and environments.
- Communicate and justify conclusions clearly and unambiguously to both specialised and non-specialised audiences.

Methodology
Learning is achieved by means of three types of activities.
Directed activities: Directed activities are theoretical and practical lectures in a computer lab. They include solving case studies and practical exercises. Lectures are the common thread of the course. Lectures serve to systematize all the content, to present the state of the art of the different subjects, to provide methods and techniques for specific tasks, and to sum up the knowledge to learn. Lectures organize also the autonomous and complementary work done by the students
Supervised activities: Supervised activities are focused on the execution of a semester project, consisting of a real case study, carried out through workshop hours, autonomous work and tutorials. This semester project allows to apply together all the knowledge and technical skills learnt in all the courses of the semester. The semester project is a milestone for the students and the actual demonstration that they had achieved the learning goals of all the courses of the semester. It is also the main evidence for evaluation as students should have to submit at the end of the semester a report that summarizes the whole project and do an oral presentation.
Autonomous activities: Autonomous work of the students includes personal readings, data and documentation search, complementary exercises and the personal development of the semester project.
The activities that could not be done onsite will be adapted to an online format made available through the UAB’s virtual tools. Exercises, projects and lectures will be carried out using virtual tools such as tutorials, videos, Teams sessions, etc. Lecturers will ensure that students are able to access these virtual tools, or will offer them feasible alternatives.

Assessment
In the event that assessment activities cannot be taken onsite, they will be adapted to an online format made available through the UAB’s virtual tools (original weighting will be maintained). Homework, activities and class participation will be carried out through forums, wikis and/or discussion on Teams, etc. Lecturers will ensure that students are able to access these virtual tools, or will offer them feasible alternatives.
CONTINUOUS EVALUATION
a) Evaluation procedure and activities:
Evaluation of the course is based mostly on the semester project, that comprises two evaluation activities. The elaboration and submission of a synthesis report and the oral presentation of the project done. Given the technical content of the course, the weight assigned to the project report is 45% of the total course grading, assuming that it is the most appropriate means to explain all the technical details of the project, and a weight of 25% at the oral presentation. The course assessment is completed with the evaluation of the practical exercises done along the course, that account for another 30% of the total course grading.
Except when expressly noticed, all the evaluation activities (report and oral presentation of the semester project, as well as practical exercises) have to carried out individually.
Time assigned to each evaluation activity includes the time spent in making all the material evidences for evaluating each activity (e.g., writing of the report, preparing the presentation slides, etc.).
b) Evaluation schedule:
1st semester project report: Making during all the semester. Submission at the end of semester, on January 22th 2021.
1st semester project oral presentation: Making during all the semester. Oral presentation at the end of semester, on January28th and 29st 2021.
Course practical exercises: Making and submission weekly or biweekly along the semester.
c) Grade revision:
Once the grades obtained are published, students will have one week to apply for a grade revision by arranging an appointment with the corresponding teachers.
d) Procedure for reassessment:
1st semester project report: It could be reassessed in the following two weeks after the submission date scheduled. Reassessment will require the submission of a new whole report in case of negative evaluation of the former report submitted.
1st semester project oral presentation: It could be reassessed in the following week after the date scheduled for the oral presentation. Reassessment will require doing again the oral presentation in case of negative evaluation of the former presentation done.
Course practical exercises: Can not be reassessed.
To have right to a reassessment the student will have to have been previously evaluated in a set of activities that account for at least two thirds of the total course grading. Therefore he or she will have to have been evaluated of the 1st semester project report (45%) and of the 1st semester project oral presentation (25%) in the dates scheduled.
The right to a reassessment will only be granted to students that, having not passed the course (e.g., having a total course grade below 5 over 10), had obtained at least a total course grade above 3,5 over 10.
e) Conditions for a ‘Not assessable’ grade:
Students will receive the grade ‘Not assessable’ instead of ‘Fail’ if they had not submitted neither the 1st semester project report nor done the1st semester project oral presentation. That is, if they only submit all or part of the course practical exercises.
f) UAB regulations on plagiarism and other irregularities in the assessment process:
In the event of a student committing any irregularity that may lead to a significant variation in the grade awarded to an assessment activity, the student will be given a zero for this activity, regardless of any disciplinary process that may take place. In the event of several irregularities in assessment activities of the same subject, the student will be given a zero as the final grade for this subject..
Assessment acitivities with a zero grade because of irregularities can not be reassessed.
