31444 - Topography T

Learning outcomes

The course provides the basic elements of Geomatics: modern terrestrial and spatial positioning techniques, photogrammetry, laser scanning techniques and numerical cartography. The course contemplates exercises in laboratory and on the field by means of surveying instruments, commercial, scientific and open source software.

Course contents

Reference systems of the classical and satellite Geodesy; coordinate systems; coordinate transformations in the plane and in space; transformations between reference systems.

Surveying elementary schemes; survey methods using GNSS (Global Navigation Satellite System) receivers.

Modern topographical instrumentations and survey methods with total stations, digital levels and terrestrial laser scanner.

Statistical analysis of topographical measurements; the propagation of measurement errors; principles of least squares; least squares adjustment of measurements using the indirect observations method. Analysis of results and precision

Teaching methods

Lectures and exercises in the Laboratory or on your own PC.

Discussion of real case studies.

In consideration of the type of activity and the adopted teaching methods, the attendance of this course requires the prior participation of all students in the Modules 1 and 2 on safety and health in the study places, in e-learning mode.

Assessment methods

The final exam is unique for the entire C.I. and verifies the acquisition of the expected knowledge and skills by carrying out a written and oral test, without the help of notes or books.

At the time of the test, students must have an identification document (Identity Card or Driving License or Passport) and a badge and show it to the examiners.

The writing consists of various types of questions (multiple choice, true-false, short open questions or basic exercises) that cover the entire program of the course. Each question is associated, and declared immediately before the exam, with a score whose total amount exceeds the maximum of 2 units (32/30). Incorrect answers do not result in score penalty. The test must be performed within the indicated time range and generally not exceeding one hour. The oral exam is held at the end of the written test following the candidates alphabetical order, and consists of a discussion of the written test and a possible oral examination with some supplementary questions, that may affect the final score by no more than +/- 3 points.

At the moment, the examination takes place in person, unless specific requests are proven and accepted well in advance by the candidates (not generally linked to the distance from the university headquarters or to situations of illness or Covid-19).

In the case of exam in online mode, the EOL platform (eol.unibo.it) will be used for the provision of the written and ZOOM application for surveillance and oral integration.

In the case of exam in online mode, it is necessary to have all the tools listed below:

• a stable internet network
• a desktop or notebook (hereafter PC) including a webcam, plugged in and connected to the Internet
• a mobile device (smartphone or tablet) connected to the electricity network and to Internet, equipped with a video camera, which will be used as means of supervision by the examiners inside the Virtual Classroom
• the ZOOM app that allows video meeting and access to the virtual classroom must be installed on the mobile device
• the possibility of using a quiet environment in one's own home, free from other people and correctly lit, in which to set up a space with the elements listed above.

Teaching tools

A significant part of the course is designed to practical activities on the field and in the laboratory, by means of commercial, scientific and open source programs.
