CARTOGRAPHY IN THE AGE OF DIGITAL TECHNOLOGY OPPORTUNITIES AND CHALLANGES Lê Minh Vĩnh Dept of Geodesy and Cartography University of Natural Resources and Environmental of HCMC In the mid-to-late 20th century, advances in electronic technology have led to revolution in cartography Basing on computer-mapping systems, maps are produced easily and faster than ever Maps are made by computers and map-making software… What we now that there’s Google Maps… Hasn’t everything been mapped already? Are cartographers still needed? Exist or not exist? During the 20th century In the new age of Digital Technology, GIS has appeared and given Cartography many new changes that lead to opportunities as well as challenges Challenges Difficulties Past…and …Present Draw maps manually using traditional tools and technology – pens and ink Create maps using computer-based system Technology let us make many different types of maps that people can not imagine before (3D, animated, multi-scale, multi-time and multilayer, interactive, multimedia maps…) From 2D to 3D maps There are things that we can and computers cannot, before… we teach them to Cartographers should think about clarification as many as possible cartographic principles/ map design rules (which are not always clear) -> involve them into “intelligent software/ expert system” -> help map-makers make decision Last but not least… The appearance of new types of maps have led to many changes that let us concern… Traditionally, according to the distance between users eyes and maps… Wall maps 2-3 m “Hand-on” maps 25-30cm screen maps, distance ~80cm Based on these distances, we define the minimum sizes of symbols on maps, and thus, we give the rule for new type: screen maps Multi-scale maps Paper map with fixed/ predefined content and scale map in different scale -> different levels of details Bảnđồ đồtỉtỉ Bản lệ… lệ… Scale:… When and how? The appearance of new types of maps have led to many changes that let us concern with defining new concepts, new theoretical framework for them I believe that … cartographers are still needed with their new mission… Define new concepts Create new types Cartographers Give instruction Clarify Principles, rules Define new concepts Create new types Cartographers Give instruction Clarify Principles, rules Let’s carry out our mission together References Daniel Huffman, “Is Cartography dead?”, http://blog.visual.ly/is-cartography-dead/ Keith C Clarke, (1995) ed ”Analytical and Computer Cartography”, ed Prentice Hall Michael Wood, 2003, “Cartography in the age of GIS”, Geograficky Casopic Laszlo Zentai, 2012, “Does cartography still exist?”, Proceedings- AutoCarto 2012- Columbus, Ohio, USA Terry A Slocum, 1999, “Thematic cartography and visualization”, Prentice Hall THANK YOU FOR YOUR ATTENTION! ... unattractive, default-heavy maps The kind made mostly by someone throwing everything together without a lot of thought, letting their tools the thinking for them” (Daniel Huffman, “Is Cartography dead?”,... … Geo-marketing: the use of location knowledge to frame marketing efforts, using digital mapping to organize and display data for review and decisionmaking Internet maps: any thing, anytime,... projections and results live on interactive maps But also ways of using maps Not only strike increase number of users Quality Quantity In our recent research named “Usage of maps in social sciences and
