The wiki says about this supplier:
About $17 per sq km for basic 2 meter resolution photography.
I attached in the discussion page some links about another supplier:
SPOT5 satellite imagery which seems to be much cheaper : 2€ per sq.km
Here is a copy of my comments:
You might add this as possible additional source:
* http://www.spotimage.fr/
(available in english)
They have a new service for GeoTiff images online ordering:
* http://spotmaps.spotimage.com/
* http://www.spotimage.fr/web/en/2231-spotmaps-features.php
in about 30 countries.
Resolution is 2.5 m. Price is 2.0€ per sq.km (see the service price
called SPOTMaps). Minimum billing is 20€ till 1000 km2. Location
accuracy is 10 to 15 m RMS, depending on country.

Looks interesting .... but..... (there is unfortunately often a but)
A brief review of the license terms. The definition of Derived Work is
good, unless a derived map is a 'Digital Terrain Model' which we would
need to check with them.
“DERIVATIVE WORKS”: means any derivative product or information
developed by the END-USER from the PRODUCT,
which does not contain any imagery data from the PRODUCT and is
irreversible and uncoupled from the source imagery
data of the PRODUCT. Notwithstanding the foregoing, by express
exception, any Digital Elevation Model or Digital
Terrain Model (in any form whatsoever, i.e. database for instance)
derived from a PRODUCT shall never be considered
as DERIVATIVE WORKS.
This clause is good, except for the bit about Canada which breaks it
for use in OSM! It might be worth probing them on this term to see if
they could vary it.
"(i) to freely use and distribute DERIVATIVE WORKS. Notwithstanding
the foregoing, the END-USER shall not be
entitled to sell, distribute, assign, dispose of, lease, sublicence or
transfer, directly or indirectly, any DERIVATIVE
WORKS to any third party established, incorporated or located in the
territory of Canada. Before any sale,
distribution, assignment, lease or transfer of any DERIVATIVE WORKS,
the END-USER shall obtain from his
customer the written commitment to comply with this restriction, and
shall obtain from him that it be passed on to any
and all users of the DERIVATIVE WORKS.
