GRB

Open-source Project for a Network Data Access Protocol

Function/process performed.

Color vision theory that builds upon Trichromatic Theory, where there may be differences in the efficiency of detection towards particular wavelengths (e.g. delayed/lack of responses to a particular color/wavelength i.e. color blindness) and how information is received on the Cones in the eye.

Relating to the Nyquist-Shannon Theorem, it is a form of signal processing to extract values from waves.

Parameter for determining deviation of orbit from a perfect circle, where: 0 = Circular Orbit 0 - 1 = Elliptical Orbit 1 = Parabolic/Escape Orbit 1+ = Hyperbola Orbit

Errors caused by orbits of satellites (i.e.variations gravity, drag, tidal forces from other planetary satellites, etc…).

Order in survey refers to the degree of precision and accurcacy achieved during survey, they are often the Standards to a survey.

Type of Attribute, it is a measurement where data is ranked into hierarchies (comparative values to each other).

Kriging method focusing on spatially correlated components, assumes the Mean is constant over the region.

Positional data given to a relational datum (i.e. Mean Sea Level) that has a high degree of precision and accuracy often used for control.

Relationship between directions and objects.

A opening for materials to pass.

Base table for joining.

Type of Cadastral Survey, used to establish boundary and demarcation on unsurveyed areas of land.

A form of parallel projection where it aims to represent 3D objects in 2D space, projection lines are orthogonal to projection plane.

An aerial photograph excludes the scale, tilt and relief distortions like other normal aerial photographs.

Orthometric correction aims to correct distortions issure and produce the orthoimage.

See definition on Elevation.

See definition on Conformal Projection.

See description on Orthoimage.

The procedure to rectificate the aerial image from systematic sensor and platform-induced geometry errors, which introduce terrain distortions when the sensor is not pointing directly at the Nadir location of the sensor.

Time measurement devices, time is kept according to the oscillation within atoms.

On-The-Fly Survey

The period where DOP exceeds a maximum limit, and indication of unacceptable level of uncertainty existing at a particular location.

Where survey boat is moving away from the shoreline.

Used to detect and remove the outlier from other normal observations.

An observation point which is distinct from other observations.

Showing general understanding of concepts and basic ideas.

It exceeds the intended subject learning outcomes in nearly all regards.

The portion of a map or chart that overlaps the area covered by another of the same series.

The replacement of a block of stored instructions or data with another

Based on Boolean connectors, they are operations performed on input layers to produce a specific output. Type: 1) Union (A OR B) 2) Intersect (A AND B) 3) Difference (A XOR B) 4) Identity (A AND [B OR A])

Digitizing error of an overextended arc.

Web Ontology Language

Right of posession.

Precise Code

The camera consists of usual optics which focusses light on a CCD array and used to capture panchromatic images which are sensitive to all colors.

Standard type of film, the spectral sensitivity covers from UV to visible portions of the spectrum.

Given three points a,b,c on a line, and three points A,B,C on another line, then three intersection points of the follow pair (aA,Bb),(Ab,cC),(bB,Ca) are collinear.

A two-dimensional and mirror-symmetrical curve.

Displacement or difference in the apparent relative position of an object caused by a change of viewing position.

A relationship in a hierarchical database, where each child can only have one parent but each parent can have multiple child.

Sequence of particular colour with varying hues (e.g., black-brown-yellow-white).

Semivariance/Covariance model parameter representing the difference between Sill and Nugget.

Search of buried underground utilities without active involvement (generally via transmission signals) from the target (e.g. sweep and search).

A sensing device designed to receive and measure signals transmitted by other sources.

Listens to sound made by other objects to determine location/distances.

Radio antenna with low profile, can be mounted on a flat surface.

Raster based analysis for finding the least cost of travelling between cells.

Distance passed by remote sensors.
