Contents
Knowledge of definitions and fundamental algorithms of geodesy and cartography. Reading and proper use of modern maps (both in print and digital), with particular reference to the technical maps produced by Italian mapping agencies (IGM, Land Regions, Cadastre). Use and characteristics of the main instruments for geodetic surveying. Terrestrial and GPS satellite survey techniques. Knowledge of fundamental concepts and algorithms for statistical observations processing.

Handouts and other teaching materials available by the teacher on the website: http://labtopo.ing.unipg.it and on library of "Polo di Ingegneria"
Educational objectives
It is expected that the students achieve the objectives inherent to Dublin descriptors 1 (theoretical and methodological knowledge) and 2 (ability to correctly apply the theoretical knowledge) with reference to the content of the course and in particular:

Knowledge and use of the main coordinate systems of Italian and international cartography. Proper and coordinated employ of traditional and online maps (IGM, Regional Technical Maps, cadastral maps, online maps and digital globes). Basic understanding of the tools and techniques of terrestrial and satellite surveying.
Prerequisites
In order to understand and learn how to apply most of the techniques described in the course it is necessary a basic knowledge of the following topics:

- geometry and mathematics 1;

- practical computer knowledges: Text editor, CAD, spreadsheet, online searches;

- basics of English language.
Teaching methods
The course is organized as follows:

Lectures on the topics of the course.

Practice in the classroom and laboratory assisted by the teacher using computer methodologies related to the course.

Exercises outside on the use of measuring instruments and GNSS surveying.
Other information
Due to the practical character of the module, lectures frequency is advisable.
Learning verification modality
The verification of the educational objectives of teaching (examination) consists in an oral exam.

The test consists in a discussion lasting no more than 1 hour aimed at verifying : i) the level of theoretical and methodological knowledge of the course contents (Dublin descriptor 1), ii) the ability to correctly apply the theoretical knowledge (Dublin descriptor 2), iii) the ability of independent judgment in formulating appropriate comments on possible alternatives (Dublin descriptor 3), iv) the ability to expose with a proper language the course contents and summarize the results of the application of the theories studied (Dublin descriptor 4).

Extended program
Geodesy
Definition of the reference surface. Earth's gravitational field. Terrestrial spheroids and terrestrial ellipsoids. Geometry of the ellipsoid of rotation. The foundations of surveying operations. Normal sections and geodesic lines. Approximate solutions for the reference surface in the planimetric survey: tangent plane to the ellipsoid and local sphere. Calculation of curvilinear coordinates on the ellipsoid. Datum. Transformations between coordinate systems and datum.

Mapping
The general problem of mapping projections. Deformation modulus: linear, areal and angular deformation. Equivalent maps, conformal and aphylaptic projection. Gauss Conformal Projection: UTM and national Gauss-Boaga. The Cassini-Soldner projection and the map of the Italian Cadastre. The technical regional map. Numerical and digital mapping. Datum transformations.
Modern techniques of map production. Notes on Geographical Information Systems. The maps produced by the main Italian maps agencies (IGMI, Regions, Cadastre): types and characteristics. Reading and use of the maps, with practical exercises on cartographic material commonly used in Italy. Exercises in the computer lab on digital mapping and GIS.

Surveying Techniques
Instruments and techniques for the measurement of azimuth and zenith angles (theodolites). Instruments and modern techniques for the measurement of distances (electro-optic distance meter). Instruments and techniques for the measurement of height differences (levels and staff). Practical exercises on the use of surveying instruments. Horizontal positioning: classification, refinement and detail. Height determination: heights from geometric leveling and trigonometrical heights . Practical use of surveying instruments. GPS Satellite Surveying. Treatment of Observations.
