What Makes a Good Map?
        Adam Nemeth, Nearby Project
What I won't talk about tonight

Air pollution + Stereo Computer Vision




Community Databases + AGPS + Base Stations




PostGIS + Badly written SQL Selects + names
What I will talk about instead
“Cartography is a special
           kind of UX”

Maps are there
• For specific target audiences
• To solve specific use cases
• In specific contexts
That’s why
a single, global map
is hard to design
   It tries to solve everything for everyone
Target audiences
• What kind of vehicle? (ped., car, bike...)
• Is it you who's driving?
• What's the speed?
• How old are you?
• Are you familiar with the area?
People expect things to
see at once!
• Also they expect maps to be permanent
• Mobile screen is small
• Can't be overloaded with information, but
  needs enough - no legend!

• Visual Information Hierarchy in each
  and every view!

• Level of detail is important
Primary and secondary
goals
• Not all goals are told explicitly
• Orientation is a key issue
• But perhaps you need an ATM on the way...
Orientation
   •   Orientation can be anything: width of street, shape
       or color of building, a tree, a crane, brand signs...

   •   Churches are usually high buildings with a tower
       or a cross on top of them in Europe - not always!

   •   India doesn't have street names - they use petrol
       station names

   •   Chinese would prefer a McDonalds to a street
       name
Use Case Examples
•   University students expect their building names to
    be present - not meaningful for anyone else

•   There's no reason to show pathways while driving

•   A “main street” is different for a pedestrian and a
    driver

•   “entrance” is different for a pedestrian and a
    driver, not to mention parking spots

•   A metro station can have up to 10-15 exits
Cartography is complex
  Digital cartography is even more complex
You can only implement
it well while actively
trying to use it
Any questions?
Nokia Maps (mostly driving)




Google Maps (mostly pedestrian)
