OVERVIEW

The course provides the basic tools needed for the spatial knowledge of the territory, through main survey methods for the local area. Statistical methods provide the basis to check the campaigns' quality and to analise the obtained results.

AIMS AND CONTENT

LEARNING OUTCOMES

The course provides the theoretical and practical tools for the survey of the buildings using photogrammetry, laser scanner and traditional topographic tecniques. It also provides the tools necessary in cadastral updating procedures; elements of observations treatments will provide the basis for the quality control of the obtained results.

AIMS AND LEARNING OUTCOMES

The course provides the useful tools to apply the photogrammetric and laser scanner techniques to the building relief, integrated by traditional survey techniques, in addition to the cadastral procedures for the cadastral cartography (Pregeo) and Cadastre manufactured (Docfa). Finally, elements of the observations treatment provide the basis for the control of the measurements campaigns and the results obtained, by identifying and measuring accuracies schemes most appropriate, in accordance with the required precisions.

TEACHING METHODS

Lectures (30 hours) and practice (20 hours) related to the campaign survey, to the calculation and to the firsts critical analysis.

For the processing procedures we give priority to the use free and open source software to provide students.

The instrumental and numerical exercises are particularly useful in learning instrumental operating practices discussed in class, to the processing of measurement campaigns and to the acquisition of the necessary sensitivity for its analysis. Both exercises are needed to compile the technical report that is an integral part of the oral exam.

The course is held in Italian but they are available bibliographic references in English; the technical report and the examination can be conducted in English.

SYLLABUS/CONTENT

Main methods of survey available today.

Photogrammetric survey of the neighbors: the photogrammetric process, the sensors, the return process, the precision obtainable, applications and products of photogrammetry.

Laser scanner survey: operating principles, types of instruments and precision obtainable; system limits and potential of integration with photogrammetric techniques.

Traditional survey methodologies applied to buildings: optical level, principles of operation and procedures for the monitoring of buildings; total station, operating principles and procedures for the support of photogrammetric and laser scanner.

Introduction to the main services offered by the Italian Land Agency: the procedure of update of cadastral maps with Pregeo and of manufactured register with Docfa.

Elements of observations processing: concepts of precision, control of measures and results, methods of assessment and reduction of residual errors; linear transformations of the position and dispersion indexes, the mean and the variance; concepts of redundancy of measurements and their Least Squares Adjustment.

The measurement campaigns will include the photogrammetric survey, complete with topographic support, and the laser scanner survey.

The measurement campaign will lead to the drafting of a technical report to be carried out in small groups of students, in which critically analyze the survey.

It will also be possible to compare the different techniques also considering their integration.
