2. 2/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design “Graphics software no more guarantees good maps than word-processing software assures good writing” [M. Monmonier, 1993, page 12, “Mapping it out”]

3. 3/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design Cartography  Study and practice of making maps Map  A map is a symbolised image of geographical reality, representing selected features or characteristics, resulting from the creative effort of its author's execution of choices, and is designed for use when spatial relationships are of primary relevance. [International Cartographic Association, www.icaci.org] Definitions

4. 4/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design  Communicate information graphically  Answering questions like: Where is…? What is…? How many…?  Revealing (unknown) spatial relationships Why Use Maps?

5. 5/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design  What is your map for?  Different goals call for different maps Why Are You Making Your Map?

6. 6/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design  Who is your map for? Experts/novices, adults/children  What is the final medium? Computer monitor/paper (b/w or colour)/projected/posters => Resolution, colour schemes, size, more/less fine lettering and symbols Why Are You Making Your Map?

7. 7/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design The reason a map is being made suggests appropriate tools  Making maps without the computer  Making maps on the internet  Making maps with GIS Manipulate/analyse data numerically or visually: mapping in GIS Publish results as maps, export maps => GIS include basic map-making and map design capabilities  Graphic design tools Map-Making Tools

8. 8/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design Map Layout  Map body  Title  Legend (key)  Scale (graphical, numerical)  Sources, date, author etc.  Projection information  Orientation  Insets/locator maps  Explanatory text 8/18

9. 9/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design Map Layout  Arrange the elements according to the typical eye movement and the visual focus  Balance the map elements  Arrange the elements by using horizontal and vertical spaces poor layoutgood layout

Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design Map Layout  Arrange the elements according to the typical eye movement and the visual focus  Balance the map elements  Arrange the elements by using horizontal and vertical spaces poor layoutgood layout

11. 11/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design Intellectual and Visual Hierarchies Intellectual hierarchy (after Dent 1999) 1.Thematic symbols, Title, legend material, symbols and labeling 2. Base map - land areas, including political boundaries, significant physical features 3. Base map - water features, such as oceans, lakes, rivers 4. Important explanatory materials - map source and credits, Other base map elements - labels, grids, scales [after Dent 1999]

12. 12/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design Intellectual and Visual Hierarchies Visual hierarchy  Figure-ground phenomenon: most primitive form of perceptual organization (= automatic mechanism)  Objects that stand out against their background are referred to as figures, their formless backgrounds as grounds  Layering of data (subtraction of weight) enhances representation of ordered information

13. 13/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design Intellectual and Visual Hierarchies Visual hierarchy Perceptual grouping of elements Shape Size Texture Proximity Colour

14. 14/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design Intellectual and Visual Hierarchies Visual hierarchy Layering and outlines

15. 15/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design Intellectual and Visual Hierarchies Visual hierarchy

16. 16/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design Intellectual and Visual Hierarchies Visual hierarchy

17. 17/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design Intellectual and Visual Hierarchies Visual hierarchy  Make a list of the elements on your map  Arrange them from most important in your map’s intellectual hierarchy to least important  Select visual symbols/a visual hierarchy which reflect(s) these priorities

18. 18/18 J. Siemer – U of R – Winter 2006 GEOG 409 – 1 Cartography Principles of Effective Cartographic Design Intellectual and Visual Hierarchies Visual hierarchy - summary  Visual difference separates figure from ground  Figure has more detail than ground  Sharp edges/outlines help separate figure from ground  Visual hierarchy is enhanced when ground appears to continue behind the figure  Coarser texture tends to stand out as figure  Elements with simple closed shapes tend to be seen as figure
