Types of Maps

A map is a graphic depiction of all or part of a geographic realm in which the real-world features have been replaced by symbols in their correct spatial location at a reduced scale (Clarke, 2001)

Map classification by Scale;

1. Large-scale maps [1:10000 and larger]

  • Cadastral maps - show the location of property ownership lines, the size of the land parcel, etc. e.g. general plans
  • Topographic maps - are based on precise surveys, show topographic details such as relief, natural & man-made features
  • Engineering maps - are detailed maps, used for guiding engineering projects e.g. bridges, dams etc. & aids to estimating the construction costs of such projects
  • Bathymetric maps - show water depths and the configuration of the underwater topography

Types of Maps

Map classification by Scale;

2. Small-scale maps [1:50000 and smaller]

  • Wall maps - are generally drawn on large size paper or on plastic base for use in classrooms or lecture halls
  • Atlas maps - represent fairly large areas and present highly generalised picture of the physical or cultural features

Types of Maps

Map classification by function;

  • Physical maps - Relief, geological, climatic, soils maps etc
  • Cultural maps - Political, population, economic, transportation etc

Types of Maps

Map classification by subject;

  • Reference maps - Geographic features and map elements on a reference map tend to be treated and represented equally
  • Thematic maps - depict particular theme & shows the spatial distribution of a single attribute or the relationship among several attributes
  • Dynamic maps - Simply interactive representations of the earth, e.g. online, via mobile phone
