List of surveying instruments

Surveying equipment is being used under most stressful conditions. The equipment is exposed to extreme weather conditions, used in dusty construction areas and is subject to bumpy transportation. Proper care in the method by which equipment is used, stored, transported, and adjusted is a major factor in the successful completion of the survey. Lack of good maintenance practices not only causes unjustified replacement costs, but also can serious the efficiency and accuracy of the entire survey. Also See: Levelling Survey. Surveying instruments, which include theodolites, levels, total stations, electronic measuring devices, and GPS receivers, are designed and constructed to provide years of reliable use. The shafts, spindles, pendulums, and electronics of precision instruments, although constructed for rugged field conditions, can be damaged by one careless act, or continued negation prescribed procedures for use, care, and adjustment of the instrument.

From determining property boundaries to preparing construction sites, surveyors rely on certain equipment to do their jobs properly. Below is a summary of eight different types of surveying equipment and their uses:. Taking accurate measurements is one of the most important tasks a land surveyor must complete. There is a variety of tools that can be used to take measurements including tapes, rulers , chains, and laser devices. Pocket tapes are ideal for small-scale measurements while measuring wheels , nylon coated steel tapes Nyclad tapes , and fiberglass tape measures can be used for larger distances.

Oh no, there's been an error

Fortunately, total stations provide a solution. These lightweight and portable machines help you get the correct data you need to ensure quality construction and timely project completion. But how does a total station work, and what is the use of a total station? A total station is an optical instrument commonly used in construction, surveying and civil engineering. It is useful for measuring horizontal angles, vertical angles and distance — it does this by analyzing the slope between itself and a specific point. A high-quality total station camera combines surveying, imaging and high-speed 3D scanning into one precise and reliable instrument. It blends the latest field technologies with advanced technical features to create a tool that is trusty and dependable in demanding field situations while producing accurate results for analysis and engineering.

Other tools used by a surveyor to measure distance can be a steel tape of lengths of up to ' and the modern electronic distance measuring devices that can measure distances in excess of several miles with the use of reflector prisms. In fact, the first men to land on the moon left behind a grouping of reflector prisms that allowed surveyors and scientists to measure the distance from the earth to the moon to an accuracy of just a couple of feet. A plain compass has no adjustment and always reads magnetic north. A vernier compass has an adjustable scale that allows for the "setting off" of the magnetic declination and the compass can then directly read true north. Transit Theodolite The transit and theodolite are used by the surveyor to measure both horizontal and vertical angles.

Он не очень-то об этом распространялся. Сьюзан трудно было поверить в такое удачное совпадение. - Его погубило слабое сердце - вот так. Слишком уж удобная версия. Стратмор пожал плечами. - Слабое сердце… да к тому же еще испанская жара.

Энсей Танкадо умер. Вина ляжет на АНБ. - Мы успеем найти его партнера.

Сьюзан ни слова не сказала об истинной причине своей беседы с Дэвидом Беккером - о том, что она собиралась предложить ему место в Отделе азиатской криптографии. Судя по той увлеченности, с которой молодой профессор говорил о преподавательской работе, из университета он не уйдет. Сьюзан решила не заводить деловых разговоров, чтобы не портить настроение ни ему ни. Она снова почувствовала себя школьницей. Это чувство было очень приятно, ничто не должно было его омрачить.

 Я что, бухгалтер. - Нет, милый, ты директорский автопилот. Надеюсь, не забыл.

Опустив руки, он незаметными быстрыми движениями соединял кончики пальцев. Перед его глазами появилось сообщение, которое он должен был отправить. ТЕМА СООБЩЕНИЯ: П. КЛУШАР - ЛИКВИДИРОВАН Он улыбнулся. Часть задания заключалась в немедленном уведомлении.

 El queria que lo guardara. Он хотел его оставить, но я сказала. Во мне течет цыганская кровь, мы, цыганки, не только рыжеволосые, но еще и очень суеверные. Кольцо, которое отдает умирающий, - дурная примета. - Вы знаете эту девушку? - Беккер приступил к допросу.

 Вы этого не сделаете, - как ни в чем не бывало сказал Хейл.  - Вызов агентов безопасности разрушит все ваши планы. Я им все расскажу.
