GIS Practice Exam with Verified
Solutions
stores non-spatial information in the form of logically related two-dimensional tables
with Feature IDs - ANS-relational database model
A spatial data model that uses points and their x-y coordinates to construct spatial
features of points, lines, and polygons (a discrete representation of reality) - ANS-Vector
Data Model
set of rules that an object as to abide by in order to be considered an object in GIS -
ANS-Planar Enforcement
the science of obtaining data without coming into contact with the earths surface - ANS-
Remote Sensing
the use of algebraic expressions to represent a model of reality - ANS-Spatial modelling
building of algebraic expressions or equations in GIS where the terms of the equations
represent spatial themes in the form of raster map or images - ANS-Map Algebra
process of converting positional data of objects and their elements to reference systems
relative to real position on earth (assigning map coordinates and spatial locations with
reference to centre of earth) - ANS-Georeferencing
interpolation based on bicubic polynomials in 2D - ANS-Bicubic spline
local operators, pixel by pixel transformation of an image - ANS-Filtering
optimal interpolation technique which defines a neighbourhood based on the law of
spatial dependence and autocorrelation function, and determines weights of neighbours
within that neighbourhood (points closer together are similar, and different further apart)
- ANS-Kriging
minimum linear dimension or the smallest unit of geographic space for which data are
recorded - ANS-Resolution
the branch of geometry that deals with the properties of features that are unchanging
and that depend on context - ANS-Topology
