I have put together a proof-of-concept PHP script that enables Google
Earth to use VO Cone Search data.

Maximum search radius is set to 0.1deg to limit the download time.

a cone search with search radius set to half of the field of view, up to
0.1 deg. Results will be displayed after the download is completed.
Watch the animated icon under Temporary Places.
When navigating to another location, right-click on "USNO-1B catalog"
under Temporary Places and then refresh, that will perform a new cone
search centered at the new location.

of service already.
Please let me know if there is a problem with the link.
(Known bug: the apache server sometimes crashes, just refresh and
