1. Plane Tabling
Plane tabling is a traditional survey method used for creating maps directly in the field. It allows for simultaneous observations, mapping, and contouring but has become largely obsolete with the advent of modern surveying technologies like GPS and Total Stations. The theodolite is highlighted as a versatile instrument for measuring angles and levels, with various types including electronic models that enhance precision in survey work.
Sections
Plane tabling is a graphical surveying method for map preparation conducted in the field, enabling simultaneous observation and contouring.
Theodolite surveys utilize theodolites to measure angles and lines of sight for accurate positioning in surveying.
Plane tabling involves creating maps in the field with minimal office work.
The advantages of plane tabling include real-time visualization of terrain, while disadvantages include reliance on weather conditions.
The theodolite can measure both horizontal and vertical angles, essential for accurate surveying.
