QUESTIONS & ANSWERS 2024/2025
ASCI FILE - ANSWERSIs a point file that is non-binary
USGS DEM - ANSWERSIs a file format developed by the U.S. Geological for storing elevation models.
TIFF FILE - ANSWERSA tag-based file format for storing and interchanging raster images
Triangulated Irregular Network (TIN) - ANSWERSRepresents a topographic elevation surface by a
tessellation of non-overlapping triangles, with elevations at their corners. Three-dimensional
visualizations are readily created by the rendering of the triangular facets.
Digital Surface Model (DSM) - ANSWERSIncludes ground surface, vegetation and man-made objects.
DSM demonstrate the natural and artificial features on the Earth's surface. Digital Surface Model may be
useful for RF planning, landscape modelling, city modelling, visualization applications and more
Digital Elevation Model (DEM) - ANSWERSA 3D computer graphics representation of elevation data to
represent terrain, commonly of a planet, moon, or asteroid. A "global ___________" refers to a discrete
global grid.
What is Vector Data? - ANSWERSIs a collection of points, lines, polygons.
What is Raster Data? - ANSWERSIs stored as pixelated and gridded.
Tital Datum - ANSWERSIs a standard elevation determined by certain phases of the tide.
Geodetic Datum - ANSWERSAn abstract coordinate system with a reference surface (such as sea level)
that serves to provide known locations to begin surveys and create maps.
, Geoid - ANSWERSThe actual shape of the Earth.
Geoid Model - ANSWERSIs a global mean sea elevation to measure precise surface elevations.
Dominant Tenement - ANSWERSIs a real estate parcel which benefits from an easement on an adjoining
property. One who has the right of way.
Servient Tenement - ANSWERSLand encumbered by an easement to an adjoining property. One who
owns the land.
Standard Deviation - ANSWERSA computed measure of how much scores vary around the mean score. In
surveying you want a small distribution because it has less spread and more precise measurements.
Accuracy - ANSWERSIs how close measured value is to the standard or true value.
Precision - ANSWERSA measure of how close a series of measurements are to one another.
Statue of Frauds - ANSWERSRequires certain contracts to be in writing to be enforceable.
Static Surveys - ANSWERSStatic GPS surveying is a relative positioning technique which employs two (or
more) stationary receivers simultaneously tracking the same satellites. One receiver, the base receiver, is
set up over a point with precisely known coordinates such as a survey monument. The other receiver,
the remote receiver, is set up over a point whose coordinates are unknown. This method of surveying is
based on collecting simultaneous measurements at both the base and remote receivers for a certain
period of time, which, after processing, yield the coordinates of the unknown point. This type of survey
is primarily used to create control where no control exists to very high accuracies.
Kinematic Surveys - ANSWERSReal-time kinematic (RTK) is a surveying technology that measures the
relative positions using two Global Navigation Satellite System (GNSS) antennas in real-time with better
accuracy. The errors found in GNSS results are determined and corrected using RTK technology.
OPUS - ANSWERSPopular NGS tool which helps survey-grade GPS users tie their local surveys to the
National Spatial Reference System. By leveraging the processing software used to manage the
