GEO1141 Land Surveying Instruments and Computations
On the basis of
- GEO1151 GIS Intro I
- GEO1091 Law, basic
Expected learning outcomes
The aim of this Practical Land Surveying course is to learn how to use instrument and computing skills to carry out realistic land surveying tasks. Course theory is concerned with the mathematics and geometry of the Figure of the Earth, of coordinate systems and mapping projections. Practical work covers the methods of employing instrumental systems in accordance with land surveying quality standards and practices. The course is project based, and demands that students work closely together to design, plan and carry out their projects and subsequently document and present their results.
Mathematics and geometry:
The lessons learned on the GEO1141 Land Surveying Instruments and Computations course supplemented with the necessary mathematical and Earth geometry topics:
- Basic relevant differentiation (including partial differentiation)
- Basic relevant matrix algebra
- Coordinate transformation, including developing transformation parameters
- Introduction to survey adjustment by Least Squares
- Datums, coordinate systems (Earthg centred, geodetic, plane and local)
- Geometry of the Ellipsoid
- The Geoid
- Systems used in Norway (with historical background):
-- EUREF89 – ED50 – NGO1948
- Surveying methods:
Topics here focus on the use of instruments and measurement systems to produce the required data using methods which satisfy published quality standards:
- GNSS static vector measurements (excluding network measurements!)
-- Establishing and operating a local GNSS reference;
-- ”Stop’n’Go” vector measurements (excluding network measurements!)
-- RTK measurements
---- Using a local reference
---- Using CPOS
- Survey resection
- Trigonometric height measurement
- Tunnel surveying
- Industrial survey measurements
- Detail surveys
- Staking out surveys - roads, building sites, buildings
- Machine control - installation, measurement, operation
- Property surveys
Techniques for visualisation are presented together with the latest developments in interdisciplinary electronic cooperation
- Digital data compatibility issues
- 3D visualisation using programs such as SketchUp
- Building measurement and digital documentaion using programs such as Revit
