Active Leakage Control

Procedure/rule/formula to be followed in calculations for problem-solving.

Jagged edges in raster images.

Visualization Technique (Underground Utility). Where engineering drawings and map/imagery are placed side-by-side to show location and specifics of utilities/facilities/services.

Establishing zero reference point for the survey network for a given project area.

Surveys to aid in planning, design, and construction of roads, railways, and utilities (e.g. pipes) to establish linearity within constructs.

Having generic and transferable aspects of learning. Attributes: • Effective Communication; • Interpersonal Skills; • Critical Thinking; • CreativeThinking; • Entrepreneurship concepts and ideas.

Distribution and assignment of features/resources in network.

Data file containing satellite orbit information, transmitted within Navigation Message.

A remote sensing method by means of a line of several fixed sensors which record reflected radiation from the terrain along the satellite's direction of movement, creating scan-line strips that are contiguous or that overlap slightly, thereby producing an image.

Electric current that reverses direction of current at set regular intervals of time.

Act of combining one or more allotments/properties of land into a single allotment/property.

Background sound (energy) at a given location.

Data ambiguity suggests interpretation or intention of data cannot be definitive.

Wave Property. Determines the 'Loudness' (energy) of the wave.

Modulation technique on radio waves, which varies the strength of the carrier wave in proportion to another waveform (frequency is constant).

A pair of superimposed images in complimentary colours (i.e., red and green) that will produce stereo effect when viewed with appropriate hardware.

In a stereopair images, one photo is porjected through a cyan filter and the other through a red filter.

Special type of Convex Lens fitted between eyepeice and object glass inside telescope, it is used to reduce stadia constant to zero.

Models based on real world events/occurances.

Mask that limits analysis of raster data, where cells with no values are considered to be outside of the mask.

To determin the positions in a stereomodel through mathematical simulation of light ray projection.

To consider in detail and subjected to an analysis in order to discover essential features or meaning.

Angles below horizontal plane.

Angles above the horizonal plane.

Angle between equatorial plane of Earth and orbital plane of satellite.

Distortion to angles displayed on map due to projection and transformation, angles displayed may not reflect reality.

Errors accumulated within the angle during a traverse, should solely consist of random errors in measurements.

Spatial property describing an existince being directionally dependent, where changes in spatial dependency can lead to a change in distance and/or direction between two points.

Performance value of antenna's directivity and electrical efficiency.

Effects due to the efficiency of antenna, available power for radiation, and power applied at antenna terminals.

Loss of power due to mismatch between antenna and transmitter.

Point tied to base of antenna from Antenna Phase Centre.

Hardware attachment for dividing GPS antenna signal to two receivers.

Technique for smoothing edges of raster images.

Code encryption technique used on control access on codes in GPS control units.

Receiver's ability to lock without being given a correct beginning position and time.

Application Programming Interface

A point in orbit where the satellite is the furthest from Earth.

GIS Operation that creates new objects/layers/data by adding and/or piecing together objects/layers/data.

Set functions, procedures, protocols and routines for building software application.

Require students highly appreciate the theories and use them in practical problems.

Appreciate the given knowledge and inspire more ideas

Water permeable rock body/layer where groundwater could be stored.

Augmented Reality

Datum used for small works and is generally not related to a set reference system.

North directionality as defined by user without reference to any coordinate system.

Line feature formed from a series of interconnected points.
