  2. Description • Objectives • The main components, or building blocks, of a map • The qualities of a map that are important in communicating information to map users • The types of maps that can be developed to visually and quickly communicate information to an audience 2 Hungary, 13-18 August 2012

  3. Mapmakers need to understand… • The objective(s) of the map (the message) • The people who may use the map (the audience) • The data that will be displayed in the map (the info • rmation available) • The use of graphics software for displaying map information • The final format of the printed or digital version of the map (the product) 3 Hungary, 13-18 August 2012

  4. Bibliography M.J. Kraak and F. Ormeling (2009): Cartography: Visualization of Spatial Data. Prentice Hall T. Slocum (2003): Thematic Cartography and Geographic Visualization. Prentice Hall. Teaching and learning methods Lectures, lab work, self-study on articles in magazines Required infrastructure Class room with computer projector, computer laboratory with GIS software and data Assessment To pass this module, the students are required to complete all exercises; successfully present the final project and pass the written exam 4 Hungary, 13-18 August 2012

  5. Map components • Symbology • Direction • Scale • Legend • Locational inset • Neatline • Typography • Color and contrast • Ancillary information (caveats and disclaimers) 5 Hungary, 13-18 August 2012

  8. Color and contrast • People associate colors of mapped features with events, emotions, and socio-economic status • Although men and women react similarly to color, some reactions may vary depending on culture (Valdez & Mehrabin 1994) • How do you react to different colors?

  12. Annotation Annotation is a feature class Hungary, 13-18 August 2012

  13. What should be on your map? Hungary, 13-18 August 2012 Audience- are they all familiar with your study area? Is an inset required? Will others need to track your sources ? Do you need to record where the map is stored? Are revisions expected or will the study area change (date)? Title, scale, author, and north arrow are safe bets Publication outlets may have their own guidelines

  14. Common map problems Hungary, 13-18 August 2012 • Wrong audience • Omitting a necessary element • Too much clutter (symbology) • Too much detail (annotation) • Plotter or printer produces something different than what you see on the screen
