72741 - Cartography and Spatial Data Management

Learning outcomes

The course aims to examine in depth the aspects of classical and digital cartography and provides elements related to the modern geomatic techniques for the monitoring, representation and analysis of the territory. The Geographic Information Systems are introduced and the current techniques for surveying and processing data for cadastral purposes are described.

Course contents

The Topography and Cartography course provides the basic elements of Geomatics, treating in a modern way the techniques of terrestrial and spatial positioning, photogrammetry, laser scanning and numerical cartography. In integration with the theoretical lessons, practical exercises are organized, to make the student able to perform topographic-photogrammetric surveying operations using the latest generation instruments and to process the acquired data in the lab.

Contents:

Theoretical bases of cartography: the general problem of cartographic projection; types of projections; classification of maps; deformations in a cartographic map; the concept of scale and error in a map; Gauss conformal projection and correspondence formulas; Italian cartography; The UTM-UPS system; The Gauss Boaga system.

Introduction to laser scanner: classification of laser systems; the LIDAR system; the mobile laser scanner; fields of application of laser systems.

Introduction to photogrammetry: historical information and the transition from analogue to digital photogrammetry; the central projection and the equations of collinearity; the design of an aerial and terrestrial photogrammetric survey; examples of final products obtainable by photogrammetry. The photogrammetric process: classical phases; distortions in a frame; the internal orientation with the correction of the image coordinates. The external orientation of a photogrammetric block; precision in the photogrammetric restitution in the normal case.

Digital photogrammetry. Digital images: radiometric and geometric resolution. Methods for Stereoscopic Digital Vision. The Image Matching. The digital orthophoto. Errors in a frame. Photoplans and Orthophotos. Resampling of a digital image.

Numerical cartography: methods for the production of numerical cartography; restitution and vectorization; vector files and raster files: formats and characteristics; georeferencing a digital image.

The Geographic Information Systems.

The theoretical lessons are integrated with practical exercises using free and open source software QGIS.

Teaching methods

Lectures and exercises in Laboratory or on personal computer using Open-Source software.

Analysis and discussion using examples of real cases.

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

The course includes exercises in laboratory or on personal computer to complete and deepen the acquired theoretical knowledge.

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.
