Good afternoon.
I'm not sure if this is of interest to anyone, but I figured there may
be some of you who use 15m-30m imagery from Landsat for various
purposes.

Subject: Landsat announcement
Greetings,
I just received the following announcement about the USGS plans on
making all Landsat data available for no-charge.
Today, the USGS released a technical announcement, outlining the plan
for the release of no-charge Landsat data. Over the next 9 months, we
will be opening up the Landsat archive for no-charge ordering. Please
see the announcement below for details, and feel free to contact any of
the Landsat staff for more information.
Imagery for Everyone...
Timeline Set to Release Entire USGS Landsat Archive at No Charge.
RESTON, VA - The USGS Landsat archive is an unequaled 35-year record of
the Earth's surface that is valuable for a broad range of uses, ranging
from climate change science to forest management to emergency response,
plus countless other user applications. Under a transition toward a
National Land Imaging Program sponsored by the Secretary of the
Interior, the USGS is pursuing an aggressive schedule to provide users
with electronic access to any Landsat scene held in the USGS-managed
national archive of global scenes dating back to Landsat 1, launched in
1972. By February 2009, any archive scene selected by a user - with no
restriction on cloud cover - will be processed automatically to a
standard product recipe, using such parameters as the Universe
Transverse Mercator projection, and staged for electronic retrieval. In
addition, newly acquired scenes meeting a cloud cover threshold of 20%
or below will be processed to the standard recipe and placed on line for
at least six months, after which they will remain available for
selection from the archive.
Newly acquired, minimally cloudy Landsat 7 Enhanced Thematic Mapper Plus
(ETM+) data covering North America and Africa are already being
distributed by the USGS over the Internet at no charge, with expansion
to full global coverage of incoming Landsat 7 data to be completed by
July 2008 (see timeline below). The full archive of historical Landsat
7 ETM+ data acquired by the USGS since launch in 1999 will become
available for selection and downloading by the end of September 2008.
At that time, all Landsat 7 data purchasing options from the USGS,
wherein users pay for on-demand processing to various parameters will be
discontinued.
By the end of December of 2008, both incoming Landsat 5 Thematic Mapper
(TM) data and all Landsat 5 TM data acquired by the USGS since launch
(1984) will become available, with all Landsat 4 TM (1982-1985) and
Landsat 1-5 Multi-Spectral Scanner (MSS) (1972-1994) data becoming
available by the end of January 2009. All Landsat data purchasing
options from the USGS will be discontinued by February 2009, once the
entire Landsat archive can be accessed at no charge.
Landsat scenes can be previewed and downloaded using the USGS Global
Visualization Viewer at http://glovis.usgs.gov [under "Select
Collection" choose Landsat archive: L7 SLC-off (2003-present)]. Scenes
can also be selected using the USGS Earth Explorer tool at
http://earthexplorer.usgs.gov [under "Select Your Dataset" choose
Landsat Archive: L7 SLC-off (2003-present)]. For further information on
Landsat satellites and products, see http://landsat.usgs.gov
End of official message
Just as an FYI - to clarify some points in the announcement. This plan
will only allow 1 recipe of data to be produced. L7 data will not have
any gap correction applied. The 20% or less cloud cover images will be
processed automatically, the higher cloud cover scenes will be processed
as ordered with no plans for prioritization of orders.
