I think anybody can make use of spatial data provided freely available Eg,google earth
Maintaining a GIS for a country is essential for legal framework,if not for that daily changing earth crust is to be incorporated in a GIS system is of no value.
I think time to come everybody can share data as at present except the controle network of a particular country,
For example I am allowed to incorporate any data to Google earth around my location!
As this is just my idea ,your comments and feedback appreciated.
