Key words
progression of errors, teledetection, photogrammetry, hydrography, bathymetry, GNSS, underground infrastructure
Objectives
- Analytical data processing: After completing this component the student is able to calculate standard deviations for each measured or calculated value. He/ she is thereby able to stipulate the exactitudes of calculated and measured values, perform adjustment calculations and determine whether the obtained values meet the postulated requirements. On the other hand a feasible method can be stipulated by means of the postulated requirements.
- Introduction to teledetection and photogrammetry: impart the basic concepts concerning teledetection, aerial photography, photo interpretation, photogrammetry, photogrammetrical restitution.
- Special surveying techniques: this component aims at treating some surveying methods, which because of specific techniques and/ or requirements, deviate from the "ordinary" land surveying methods. In this component are taken into consideration: GNSS, bathymetry and the problems concerning underground utility lines.
Topics
- Analytical data processing: least squares method, solving problems concerning standard deviation, adjustment techniques, progression of errors.
- Introduction to teledetection and photogrammetry: basic concepts concerning teledetection, definitions, aerial photography, photo interpretation, photogrammetry, photogrammetrical restitution, stereoscopy, ortho photo, film types, scanners, earth observation satellites, …
- Special surveying techniques:
- Hydrography and bathymetry: description and demarcation of the field, overview of methods for horizontal and vertical positioning on and under water, bathymetry: under water acoustics, single beam, multibeam, side scan sonar, tides, tide measuring, calibration, exactitudes, presentation forms. The theory is complemented with a company visit(s) and attending seminar(s) depending on the offer.
- Undergound utility lines: developments in Flanders and neighbouring countries concerning the exchange of information, excavation procedures, detection and measuring techniques, registration in a CAD- and/or GIS- environment.
- GNSS: the basic knowledge is expanded with a more in depth study of software, field work, developments, seminar(s).
