Surveying

a rule with measurements marked at fixed distances. The person who holds it is a rodman.

a special kind of transit that gives more accurate readings of angles than a standard transit.

an aerial surveying, an overlapping arrangement of photographs that eliminates distortion at the edges of the pictures.

the measurement of someone or something from head to foot or from base to top

a horizontal plane or line with respect to the distance above or below a given...

a point whose elevation has been previously determined and marked. It is used as a basis for additional measurements.

a tube containing a fluid that has an air bubble in it bọt thủy, ni-vô bọ

an instrument used to establish a horizon tal line of sight, usually by means of a spirit level

the space (usually measured in degrees) between two intersecting lines

measuring the earth‘s surface

a map marked with contour lines

a special quality or trait that makes a person, thing, or group different from others

determining underground conditions, such as types of soil and rock beneath the surface.

lead weights attached to a line to show the direction of gravity.

the action or fact of raising or being raised to a higher or more important

the length of the space between two points

a telescopic device that can be used for measuring distances and horizontal and vertical angles. The person who uses the device is a transitman.

a line which marks the limits of an area

a kind of telescope with a bubble level

the lines on a map that indicate points of equal elevation (height).

an alidade is another kind of telescope used to measure both distances and vertical angles. It is set on a plane table (a flat table), which a surveyor can use as a drawing board to make maps in the field.

lines in a transit that are used in determining distances

measuring distances with less than the full length of the tape.

the fact of being curved or the degree to which something is curved

Collection of data in the field as a basis of studies on a proposed project.

in line with the direction of gravity.

perpendicular to the force of gravity

vertical angles are the angles opposite each other when two lines cross

in geodetic surveying, measuring a network of triangles based on points on the earth‘s surface.

a size, length, or amount known by measuring something

the necessary items for a particular purpose
