GRB

Surveying method between two points at great distances, where height measurements are taken at both directions to elliminate possible atmospheric and curvature errors.

Test/Check for biases in alignment and offsets, involves running reciprocal lines at various speeds and results are compared against prior sweep/swath runs.

See definition on Cartesian Coordinate.

Map Projection with equal spacing of meridians.

The procedure rectificates the image from various error and distortion.

See definition on Quadrantal Bearing.

Levels of points calculated through Levelling adjustment, where level of points are reduced (referred) to a datum.

Observations/measurements taken in addition to specified number of measurements in a survey to strengthen the network.

Data defining set of values permitted to be used.

Point with positional data (coordinates) of high order (high degree of accuracy and precision) for use of reference and adjustment of subsequent points in the survey.

Constant given to the difference in the centering of the instrument (geometric center) over a location and the electronic center of the instrument.

Wave Property. A change in speed of waves when travelling between different mediums (e.g. Air-to-water).

Errors resulting from the lack of focus of light.

Value describing the change of light and/or other radiation when travelling from one medium to another.

Area of land having a definable characteristic but may not be bound by physical or fixed boundaries.

Placement of infrastructure, settlement growth and land-use allocation for a larger regional area.

Find a function which is suitable for the provided data.

A procedures which is available for regression analysis used to seek to assess the validity of a model in any of a number of different methods.

Interpolation method using a number of independent variables and dependent variables in a regression equation.

The continuous sampling at a given point.

When results/measurments deviates from the mean by a large amount, it does not belong to the same normal distribution and therefore is reasonable to reject such observations (usual practice if deviation is three time standard deviation).

To make connections between ideas and cocepts.

Collection of interconnected tables.

DBMS based on relational model.

""Link/Connection between fields of different tables. Type: 1) One-to-One 2) One-to-Many 3) Many-to-One 4) Many-to-Many""

Expressed as a ratio, it is the precision of a measurement given its value.

Consistency of measurement.

Map with hill and valley features, often depicted by contour lines, used to express elevation of terrain.

Remote sensing is the science used to obtaining information about an object,area,or phenomenon through the analysis of data acquired by a non-contact device.

Rendering is the process using computer programs to produce an image from a 2D or 3D model.

Code generated by the receiver, identical to the code generated by the satellite, for use of identifying propagation delay.

Simple fraction and/or ratio to depict scale of image (e.g., 1:1000, 1/2500)

Projection of spatial data between different coordinate systems.

A process used to determine the pixel values to fill into the output matrix from the original images matrix

Opposite of Intersection, it is a method of determining position of a point through observations and measurements to three other points of known coordinates/position.

A result from the comparison between the observed distances with the inverse of the distances between the adjusted position and remote shore transmitter,used to evaluate accuracy of the range of measurements.

Degree of detail that could be displayed on a map and/or image.

Actively respond to and keep track of industrial progress and development, latest technologies, and innovative ideas.

The operation aims to correct distored or degraded image data to generate a more faithful representaion of the original situation.

Surveys to recover (re-discover) previously establish property/lot boundary.
