1. relational database stores non-spatial information in the form of logically related two-dimen-
model sional tables with Feature IDs
2. Vector Data 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)
3. Planar Enforcement set of rules that an object as to abide by in order to be considered an object
in GIS
4. Remote Sensing the science of obtaining data without coming into contact with the earths
surface
5. Spatial modelling the use of algebraic expressions to represent a model of reality
6. Map Algebra 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
7. Georeferencing process of converting positional data of objects and their elements to refer-
ence systems relative to real position on earth (assigning map coordinates
and spatial locations with reference to centre of earth)
8. Bicubic spline interpolation based on bicubic polynomials in 2D
9. Filtering local operators, pixel by pixel transformation of an image
10. Kriging 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)
11. Resolution minimum linear dimension or the smallest unit of geographic space for
which data are recorded

12. Topology the branch of geometry that deals with the properties of features that are
unchanging and that depend on context
13. UTM coordinate define 2D horizontal positions and each zone is identified by a
number
14. Resampling process of fitting one map exactly to match the dimensions of another map
by a means of a set of linear transformations
15. Types of Resampling Nearest Neighbour, Bilinear interpolation, and cubic convolution
16. GIS data model suit- Vector data model; it represents discrete objects as polygons, lines, and
ed for urban environ- points which in urban environments would be hard to represent in GIS
ments without
17. Geocoding or Dis- The process of assigning a geographic location to a geographic feature on
crete Georeferencing the basis of its address (linked to a base file with known coordinates)
18. Cartographic Model flow charts that chart the sequence of analytical steps used in spatial mod-
elling detail
19. Relational database Two tuples are never identical, row and column order is irrelevant, and all
table storage values are atomic
20. Image enhancement contrast stretching and spatial filtering
operations
21. Intersect an arithmetic operation used in raster with the "AND" operand
22. Proximity a type of analysis that defines new spatial objects
23. Union the "OR" operand in the overlay of two raster maps has a pixel to pixel effect
24. coordinate system, ellipsoid of reference, projection type, and transforma-
tion equations
