- Measuring Distances
- Convert length and distance units
- Explore it,
Measurement of Angles and Directions:
- Reference meridians,
- Bearing and azimuthal declination and its variations.
- Use and adjustment of a compass,
- Vimier and micro-optic theodolites.
- Temporary and permanent adjustment.
