Aerial Photograph |
Photographs of a part of the earth's surface taken by a camera mounted in an aircraft for mapping purposes
-Consists of a series of overlapping photos taken in strips which can form the basis for mapping |

ALQUOT PARTS |
The approximately rectangular subdivisions of the township and section Method of describing large parcels of lands as being entire sections, or regular percentages of sections. Under the public land survey system employed in most southern and western states, the states were divided into townships containing 6 square miles each. Townships were subdivided into 36 sections, and each section had 640 acres. Smaller parcels are described in terms such as quarters or halves of sections. All townships and sections are numbered, so it is fairly easy to identify a particular parcel of land by reference to its section township number, section number,and then its quadrant within the section. |

ANNOTATION |

ASSESSORS OFFICE |
Creates the tax roll annually by identifying, locating and valuing all property subject to ad volume taxes in a County. |

|
AZIMUTH AND ELEVATION |
two angles which give the direction of a surveyor's telescope: -AZUMUTH- the rotation angle of the telescope around a vertical axis, measured (counterclockwise from above) from due north, a direction whose azmuth is 0 degrees. -ELEVATION- the angle the telescope is lifted above the horizontal plane. (in 3-dimension polar coordinates centered on the instrument, azimuth is F, elevation is 90 degrees -q, the direction of straight up as elevation 90 but q=0. |

|
BACKSIGHTING |
Process by which the surveyor checks for accuracy during the process of leveling once the equipment it set up and ready Examples: Manhole Cover |
|
|
BASE MAP |
Refers to a map referenced to a coordinate system that depicts the fundamental map elements such as -public land survey section corners -streets -buildings -streams -etc. which are used for locational reference |
|
|
BEARING |
Unit of direction used in denoting the direction of a line bounding an area of land- usually measured in degrees (o) , minutes ('), and seconds(") It is a horizontal angle measured clockwise BEARINGS are measured clockwise The bearing angle is the same as the azimuth |
|
|
CADASTRAL DATA |
the graphic and/or non-graphic data describing parcels which include property corners, boundaries, parcels of land, and related tabular attribute data. |
|
|
CARTESIAN COORDINATES |
2 numbers (the carteisian coordinates) - distances from two mutually perpendicular lines (cartesian axes). The distances and the axes to which they are parallel are usually marked (x, y) in a plane and (x,y,z) in space. The "origina" is the point which the axes intersects. Where 1 on x meets three on y. |
|
|
CHAIN/CHAINING |
Unit of length equal to 66' which is used especially in the U.S. public lands surveys. Surveying tapes are often still called "CHAINS" and measuring with a tape is often called "chaining" |
