WHYWHY

• It is not a problem of technology. It is a limitation of lacking of geodata to be able to be freely used on Web, and to be managed effectively. It is a question of policy.

• The value of geodata is depends on its capacity of reusing and recreating its usability by the public The key issue is

HOWHOWand recreating its usability by the public. The key issue is the Public Licensing.

Why yGoogle Map/Earth, Yahoo, & Microsoft geo‐mapping have done more valuable marketing for pp g gGIS in one year than the entire GIS industry has done its lifetime yworldwide?

Why an American company, Google, has made better i f UK i h h UK' ipractice of UK mapping than the UK's own mapping agency 

(Ordnance Survey)?

Why do many UK geo‐companies think their government‐backed agency that should be their data provider but is often regarded as a competitor?

The answers of the Guardian on March 16, 2006 & September 13, 2007 are that:The answers of the Guardian on  March 16, 2006 & September 13, 2007 are that:

“Nearly everyone agrees that electronic mapping is an important tool for public services.”

“ the data that we pay to have collected (through our taxes) and which is then used by the data that we pay to have collected (through our taxes), and which is then used by organisations such as the Ordnance Survey, is not freely available for refor re‐‐use use by UK citizens.” 

“We, and the companies that could benefit from its use, are forced to pay for it ‐ putting a b k h i f i ”

brake on the information economy.”
