Pricing policy for Earth observation data continues to be a problem fo
r both supplier organizations and user organizations: there are incomp
atible or conflicting pricing policies used by different organizations
in the Earth observation sector. This paper analyses the issues in Ea
rth observation data pricing in two ways. First, it analyses the polic
y foundations which underlie Earth observation data pricing, such as r
eturn on investment, the basis of pricing policy and access conditions
. Second, it presents five policy options for the pricing of Earth obs
ervation data, namely free data, marginal cost price, market driven pr
ice, two tier pricing and rebalancing of government funding. The paper
concludes with an analysis of the forces acting on Earth observation
data pricing policy.
