GISP 1 Conceptual Foundations Exam Questions
With Correct Answers
Datum |Shift
A |change |from |one |datum |to |another, |such |as |from |NAD27 |to |NAD83, |which |can |result |in |
substantial |horizontal |shifts |of |point |positions
Data
symbols |that |represent |measurements |of |phenomena
Geoid
shape |that |the |earth's |surface |would |take |under |the |influence |of |the |gravity |and |rotation |of |
Earth |alone, |if |other |influences |such |as |winds |and |tides |were |absent
Discrete |Data
-has |known |and |definable |boundaries
-easy |to |define |precisely |where |object |begins |and |ends
-usually |nouns
-Discontinuous
-Numerical |data |values |that |can |be |COUNTED
,Parallels
Another |name |for |lines |of |latitude
Information
data |that |has |been |selected |or |created |in |response |to |a |question |(e.g. |location |of |a |building |or
|a |route |is |data, |until |it |is |needed |to |dispatch |an |ambulance |in |response |to |an |emergency.)
Ellipsoid
-Closed |surface
-All |plane |cross |sections |are |either |ellipses |or |circles |
-symmetrical |about |three |mutually |perpendicular |axes |that |intersect |at |the |center |
What |are |three |other |names |by |which |"discrete |data" |can |be |known?
Categorical |Data
Discontinuous |Data
Thematic |Data
,Lambert |Conformal |Conic
Map |projection |on |which |SPC |system |is |based
Information |Systems
computer-based |tools |that |help |people |transform |data |into |information
Sphere
-round |solid |figure
-every |point |on |its |surface |equidistant |from |its |center
continuous |data
-Each |location |on |the |surface |is |a |measure |of |the |concentration |level |or |its |relationship |from |a
|fixed |point |in |space |or |from |an |emitting |source.
-Numerical |data |values |that |can |be |MEASURED
-Transition |between |possible |values |on |a |continuous |surface |is |without |abrupt |or |well-defined |
breaks
Geomatics
Scientific |term |for |gathering, |storing, |processing, |and |delivering |geographic |information
, -Geomatics |university |curriculum |fwould |include |land |surveying |& |geodesy, |remote |sensing, |
photogrammetry |and |other |scientific |studies.
false |northing
A |value |applied |to |the |origin |of |a |coordinate |system |to |change |the |y-coordinate |readings
What |are |4 |other |names |by |which |continuous |data |is |known?
Continuous |surface, |field |data, |nondiscrete |data, |or |surface |data
Geographic |Information |System |(GIS)
-computer-based |tool |used |to |help |people |transform |geographic |data |into |geographic |
information.
-decision |support |tool |that |combines |attribute |data |handling |capabilities |of |relational |database
|management |systems |with |spatial |data |handling |capabilities |of |CAD |and |desktop |mapping |
systems |(David |Cowen, |1988)
-enables |decision |makers |to |identify |locations |or |routes |whose |attributes |match |multiple |
criteria, |even |though |entities |and |attributes |may |be |encoded |in |many |different |data |files.
What |is |the |Difference |Between |Geomatics |and |GIS?
-Focus |of |Geomatics |is |based |on |products, |services |and |tools |involved |in |the |collection, |
integration |and |management |of |geographic |data.
-GIS |puts |data |collection, |storage, |analysis |and |visualization |into |action.
