Subject: SPIRIT project: free SPOT5 DEMs during IPY

Dear colleagues,

Find below the description of our IPY project, SPIRIT, that will deliver free
SPOT 5 DTMs and ortho-images during  IPY

=============

SPIRIT (SPOT 5 stereoscopic survey of Polar Ice: Reference Images &Topographies)
is an International Polar Year (IPY) project managed jointly by the French Space
Agency (CNES) and Spot Image. LEGOS is the scientific PI of the project. SPIRIT
is a French contribution to the GIIPSY program
(http://bprc.osu.edu/rsl/GIIPSY/).

The main goal of the SPIRIT project is to obtain comprehensive coverage of polar
ice masses with high resolution (5 m) SPOT5 stereoscopic images. The target
areas are the margins of both ice sheets (including all their outlet ice
streams) and all major ice caps and icefields in the Polar Regions.

For selected regions (upon request by the scientific community), DTMs and
orthorectified images will be derived from SPOT5 data and will be delivered for
free to polar glaciologists.
You will receive:
.    two DTMs obtained using two sets of correlation parameters (to cope with
different types of slopes)
.    two correlation masks (to easily detect gaps in the DEM that were filled by
interpolation)
.    a SPOT 5 orthorectified image with 5 m resolution

=============

How to access these SPIRIT data?

1. To browse the SPIRIT archive, you have to send a request for an access login
to hrs_ipy at cnes.fr.  At this stage, only a very brief (5 lines) description of
your scientific project is needed.

2. If some cloud-free images are available for your study area, you will then
have to submit an order form to request the SPIRIT DEMs and ortho-image. You
will be asked to sign a license agreement and will receive your SPIRIT data by
FTP.

We hope that these data will be useful for your scientific projects and will
contribute to our understanding of the Polar Regions.
