A theodolite is primarily used by surveyors, who employ this instrument to measure angles in horizontal and vertical planes for land surveying and construction projects. Additionally, civil engineers, geologists, and architects may also use theodolites to gather precise data for planning and execution of their work. This tool is essential for establishing accurate property boundaries and creating topographical maps.
The image seen through a theodolite appears upside down due to the use of a system of prisms and lenses in the instrument. These optical components invert the image as it passes through, a common feature in many optical devices. This inversion allows for precise measurements and alignment, as the user can easily correlate the view through the theodolite with the actual physical layout of the surveying area. Ultimately, this design helps maintain accuracy in reading angles and distances.
Theodolites generally can weight anything from about 1 kg up to over 10 kg depending on the age and model of the theodolites. The older smaller mechanical/optical versions are generally lighter than the larger electical versions that have come out since the 1970's. Don't forget the ancillary items (e.g. protective carrying cases, tripods, batteries and recording devices). A good site to visit is: http://www.wild-heerbrugg.com/technical_data_wild_theodolite.htm
Amundsen's team is silent as to the order in which they 'reached' the South Pole. After arriving near their destination, they spent several days there taking theodolite measurements and sextant measurements to verify that their location was exactly 90 degrees S.
"Sunset" is a noun, not a verb. The verb tense for "sunset" would depend on how it is used in a sentence. For example, "The sun will set" uses the future tense, while "The sun is setting" uses the present continuous tense.
Compass traversing uses a magnetic compass to determine directions, while theodolite traversing involves the use of a theodolite, which is a more precise instrument for measuring horizontal and vertical angles. Theodolite traversing provides more accurate results compared to compass traversing.
