  1. CARTOGRAPHY

  2. What is cartography ESRI’s online dictionary defines cartography as … “the art and science of expressing graphically, usually through maps, the natural and social features of the earth “

  3. What is on a map? • Cultural features • Roads, lakes, buildings, rivers, contours, etc. • Numeric data • income, population data (census data), etc • Physical Features • Geology, landuse, forestry, soils, vegetation, landcover etc.

  4. How is this data represented?

  5. The Earth as a Globe http://www.jonessoda.com/wordpress/wp-content/uploads/2009/04/globe.png

  6. Flat surface is needed The earth is a sphere. It has to be developed into a flat surface. To do this the globe or earth has to be flattened out or projected.

  7. Globe to flat surface http://www.genekeyes.com/CAHILL_GALLERY/1913-Cahill-rubber-ball.jpg

  8. Projections Three main classifications: • Cylindrical • Planar or Azimuthal • Conic

  10. Scales Representative Fraction 1:50,000 Verbal Statements One cm to 0.5 km Scale Bar image from http://depts.washington.edu/natmap/education/protocols/maps/map_scale_bar.jpg

  11. Scale • Large Scale • 1:5,000 …..City map • Small Scale • 1:30,000,000 …..Map of Canada

  13. Small Scale Map 1:30,000,000 Source: ArcCanada data

  14. Types of Maps • Thematic A map designed to convey information about a single topic or theme, such as population density or geology. • Topographic…. A topographic map is a detailed and accurate graphic representation of cultural and natural features on the ground. http://resources.arcgis.com/glossary/term/1109 http://maps.nrcan.gc.ca/topo101/faq_e.php

  19. Data and Mapping • Qualitative • Shows spatial distribution or a location of data e.g. geology map, soils, land use, etc. • Not dependent on numeric data • Quantitative • Shows the spatial aspects of numerical data e.g. income data, population density etc
