Problems in Earth Science Data Sharing and
Accessing



Large amount of data



Poorly catalogued



Widely dispersed


So, what do we need?



For Users:


Fast access and acquisition of Earth Science Data



For Professionals:


Data integration and sharing


Applications integration and sharing


Efficient spatial data management



For Decision Makers:


Models and accurate Predictions for future decision making.




How to achieve this?




Earth Information Exchange
