Numbers are hard to visualise and understand

Multidimensional numbers are even harder to visualise and understand

For this reason many visualisation methods have been created

12. Esociety Project @ UCL Map API http://www.spatial-literacy.org/esocietyprofiler/ 13. Good start, but how do we get better maps?

What are the problems

• Cant share easily

• Static

• No context (e.g. built environment) ....

Easy solution...

• Convert to KML and display on google maps?

• NO!

Traditional map in a GIS 14. Why NO!

KML Vector Format

• Large maps lots complex vector data

• Google maps API KML limit ~ 2meg

2 Possible solutions

• Limit complexity of the data shown keep as vector

• • E.g. London MET Police Crime

• Use Raster

• • Slippy Maps - Tiles
