Geomatics
Objectives
At the end of this curricular unit the student will have acquired the knowledge, skills and competences that will allow him:
- Understand georeferenced data specificities, distinguish between vector, raster and TIN structures
- Know how to work with scales and georeferencing systems
- Register locations with a GPS - To be able to work projects in a GIS / ARCGIS environment, namely to import / export and edit information, to cross information to generate new themes, to relate information within each theme and between themes, to construct Digital Terrain Models and to generate associated information eg exposures, slopes, accumulations and water lines) and produce maps subtitled
- Understand and know how to calculate experimental variograms, and adjust theoretical functions
- Know how to make estimates of variables in areas by simple and normal kriging from point measurements
- Plan a sampling plan of a variable in 2D space

Teaching method
The teaching uses sessions of 2 hours each: i) theoretical classes with powerpoint ii) practical classes in computer room. In the theoretical classes, the students should read the chapter of the lesson that will be taught in class and participate actively. The practical classes are based on solving practical situations, starting with realistic data sets that reproduce some of the situations that future professionals will work with. There will be a field lesson for GPS. There are three evaluation moments, two for the theoretical component (30% + 30%) and one for practice (40%). The theoretical part can be done by two written tests, in the middle and at the end of the semester, or by a final exam. In the final exam can be made note improvement. The practical part is summative evaluation, which will be based on the practical results obtained in 6 classes to be defined at the beginning of the semester. The practical component should be made and delivered in a group of two students.
