099339 - GEO FUNDAMENTALS [I.C.]
This module aims at providing fundamental notions of geomatics, in the following macro-topics: statistics, reference frames, surveying and cartography. Moreover, numerical problems are solved in the classworks: the case studies are simplified but represent typical and realistic case studies.
Risultati di apprendimento attesi
D1. Knowledge and understanding. The students will gain a preliminary knowledge and understanding of - Statistics of the observations; Least squares tool to analyze and adjust (geomatic) observations. - The Earth shape and gravity field; reference frames and coordinates to compute positions. - Terrestrial surveying techniques, surveying schemes and adjustment methods.
- The cartographice representation of the Earth.
D2. Applying knowledge and understanding. The students will be able to solve simple problems relevant to - statistical and least squares analysis and adjustment of observations; - transformation between reference frames and coordinates systems; - analysis and adjustment of observations from terrestrial surveying; - transformation from the Earth surface to a projection map.
Statistics. Observables and observations, random errors, normal distribution, variance and standard deviation, n-dimensional case and covariance matrix, mean and covariance propagation. Least squares principles and solution for linear and not linear problems. Chi square test.
Reference Frames. Earth structure and shape: geoid, ellipsoid, geoid ondulation and deflection, cartesian and geodetic coordinates. Spherical and local planar approximations.
Surveying. Instruments: bubble, theodolite, EDM, level, instrumental errors. Horizontal networks: observation equations, surveying schemes and adjustment. Trigonometric and gemetric levelling: vertical networks, observation equations, surveying and adjustment.
Cartography. History of mapping. The mapping process. Reference and projection surfaces. Perspective and analytical projections. Linear and surface scale factors. Conformal and equivalent maps. The UTM projection. Digital Terrain Models
Classwork. Transformations between coordinate and heights systems. Mean computation, variance computation: 1D, n-D; covariance propagation. Direct intersection, levelling: propagation and closure analysis. Stereo/polar coordinates computation
Mathematical formalism is used through the course, therefore having completed a basic Calculus course is highly recommended. Numerical problems will be proposed in classworks: capability to work in a computing environment is recommended.
Modalità di valutazione
Examination is performed at the end of the course through an oral examination. A 0-32 scale is used to grade each test. The exam is considered as passed with a grade ≥18/32. The grade obtained in the Geo Fundamentals  module contributes by 50% towards the final grade of the integrated course Geo Fundamental.
In the oral examination, first questions are on very fundamental points of the program. By the following questions, the capability of the student to face more complex and in-depth parts are examined. During the exam, the questions move through all the macro-topics: statistic, reference frames, surveying and cartography. At the end, the student is asked to analitycally describe a specific problem that has been posed and solved during classworks.
