Teaching methods

The course is mainly carried out through lectures with video projection and practical activities of cadastral survey, drawing construction with CAD, GIS analysis in computer rooms properly equipped.

In particular, the teaching units 3 'Fundamentals of GIS for the management of cadastral mapping data' and 5 'Survey and CAD for representation of cadastral plans' are taught entirely through laboratory activities in a computer room. These activities include synthetic explanations accompanied by extensive exercise activities conducted directly by the students with the guidance and constant support of the teacher. In this way, students who attend the course can develop in the classroom most of the work of training required for the exam. The exercise of building survey requires the completion of educational activities in the field (typically on farms) with the guidance and support of the teacher, through the use of measuring instruments made ​​available by the University.

These teaching methods are usefully complemented with activities as visits to public offices of cadastre and land registry and the organization of seminars with experienced professionals about specific issues of the teaching program.

Assessment methods

The course is part of the Integrated Course ‘Land Appraisal and Cadastral Cartography' together with the teaching: Environmental and Rural Assessment.
Therefore, the evaluation of the course takes into account jointly the level of knowledge and skills acquired by the student in relation to the contents of all of the above teachings. The knowledge and skills taught in this course are evaluated in the following way.

The exam consists of an oral test that includes both the formulation of questions related to the topics of the program of theory, both the exposure of the documents produced by the students during the exercise. This is usually conducted in groups of three students. The tutorial consists of the following activities:

• digitization with GIS software, on the basis of a properly georeferenced raster cartography, of cadastral maps of a farm indicated by the teacher;

• creation of a vector database of parcels of the land of the farm, including at least the cadastral identification of the parcels, the surface, the land-use/land-cover class;

• creation of a vector database of farm buildings;

• presentation of the layers created in an appropriate layout, on a scale typical of cadastral mapping, with an indication of the numbers of each parcel, including the thematic geographical data useful to contextualize the farm;

• architectural survey of an agricultural building (such as a tool shed or a barn) of the farm under study;

• return of the survey documents in CAD (plan, elevations, sections) paginated and printed as UNI-sized sheets;

• preparation and printing of a DOCFA model, including a plan for the inclusion in the land register of the same building (possibly internally modified according to students' choices).

The assessment is based on the knowledge of the topics in the program by the individual student, the correctness of the documents produced and the quality of the presentation.

Teaching tools

PC and projector, computer lab with CAD and GIS software.
