SPECIAL TOPICS IN SURVEYING-GEOGRAPHIC INFORMATION SYSTEMS
Konstantina Georgouli
Lectures (Theory):
Modern topographic instruments (EDM, Total Station, GPS/GNSS, Laser Scanner etc). Geometrical design of technical works: complex traversing, geometrical design of curved and straight lines, calculation of the volume of earthworks.
Digital models of the ground.
Complex topographical applications in infrastructure works (monitoring of landslides-dams, vibrations of bridges, buildings and monuments, townplanning mappings, monitoring of natural disasters such as floods, volcanos etc).
Topography and seismology: topographical methods of computation.
Geographical information systems (GIS): introduction to GIS, landmaps, multi-subject maps, applications in infrastructure works and their management.
GIS software (open access code) and familiarity through exercises.
Laboratory:
Introduction to mapping using total station. Drawing of a closed traversing for the mapping of a building complex. Determination of the nodes of a traversing and construction of relevant report.
Measurement of the lengths of the sides of the traversing.
Levelling of the nodes of a traversing and error correction. Intersection and determination of coordinates and direction of the starting note of the traversing. Measurement by a total station of the length of the sides and the angles of the traversing. Computation and correction of a closed traversing with respect to coordinates and angles. Measurement and calculation of the coordinates of the roof corners of a building and other elements around it. Drawing of a topographic diagram on the basis of code provisions. Familiarity with the use of GPS/GNSS. Calculation of the coordinates of a traversing by GPS/GNSS and electronic drawing of the diagram in accordance with code provisions.
