dumpy level

He had no dumpy level, and only the crudest measuring equipment.

The term dumpy level endures despite the evolution in design.

"I would need a dumpy level to take some shots of the actual fall of the land.

Some dumpy levels will have a bubble level ensuring an accurate level.

A dumpy level is an older-style instrument that requires skilled use to set accurately.

During night time the dumpy level is used along with auto cross laser for accurate scale readings.

Dumpy level, from a surveying instrument collection.

Heights are recorded with a dumpy level or total station by relation to the site temporary benchmark (abbr.

Common levelling instruments include the spirit level, the dumpy level, the digital level, and the laser level.

The route was surveyed using a Wye level (an early version of a dumpy level), again the first recorded use in America.

Forced to use the then conventional Y level, during the works Gravatt devised the more transportable and easier to use dumpy level.

Dumpy levelling requires shorter and therefore more numerous sights, but this fault is compensated by the practice of making foresights and backsights equal.

They are linked to the site recording system by the inclusion of known grid points and height readings, taken with a dumpy level or a total station (see surveying).

A dumpy level, builder's auto level, leveling instrument, or automatic level is an optical instrument used to establish or check points in the same horizontal plane.

The dumpy level was developed by English civil engineer William Gravatt, while surveying the route of a proposed railway line form London to Dover.

These instruments included an alidade, dumpy level, theodolite, Gunter's chain (which was replaced by a steel tape) and a solar compass or a vernier compass.

Tilting level, dumpy level or automatic level are terms used to refer to types of leveling instruments as used in surveying to measure height differences over larger distances.

Surveying helps determine accurately the terrestrial or three-dimensional space position of points and the distances and angles between them using leveling instruments such as theodolites, dumpy levels and clinometers.

More compact and hence both more robust and easier to transport, it is commonly believed that dumpy levelling is less accurate than other types of levelling, but such is not the case.

The lab has numerous surveying instruments, including dumpy levels, auto levels, total stations (EDM), digital levels, laser devices, and GPS units, and two-way radios for team communication.

Although the use of this sight may be novel for levels, the idea of using a mirror to sight a spirit level bubble from a more convenient position has long been used with surveyor's telescopic dumpy levels.
