HRS Study Team

SPOT 5 with HRS Sensor    The HRS instrument can acquire instantaneous along-track stereoscopic pairs on large areas (its swath width is 120 km). The spatial resolution of the panchromatic imagery is 10 meters. HRS is designed to acquire relative elevation accuracies between 5 and 10 meters, absolute accuracies in the range 10 to 15 meters.


You will find below the announcement of this initiative and if you are interested to be a member of this team (or to propose somebody who could be involved) we are inviting you to send to us your sollicitation, as indicated in the announcement. Of course, feel free to transfer this message to anybody who in your opinion could be interested in evaluating HRS data.
As you can imagine the number of test areas could not be too large but should be as diversified as possible in terms of landscape types (typically a number of 10 sites around the world is envisaged). Therefore it should be envisaged that HRS data and also reference data could be shared by all members of the team. In the first step the testsites will be selected according to the availability and quality of reference data which can be provided by the PI's. This selection will be made by the HRS Study Team Secretariat, composed by ISPRS representatives and HRS project representatives (from CNES, Spot Imageand IGN). We are preparing a more detailed technical note to describe the HRS capabilities and the products (images and anciliary data) generated and delivered for this HRS Scientific Assessment Program. You will receive this note if you apply for a membership and this could help you for preparing your proposal. Due date for submission is February 15th 2003.
The assessment program will begin with selection of study areas in January/February 2003. On behalf of CNES, Spot Image will deliver HRS data by June 2003. Concurrently, Study Team Members will provide ground control data. Investigators will generate and evaluate DEMs by the end of 2003. Reports of results will be presented at the ISPRS Congress in Istanbul in July 2004.
If you consider being a PI you should join a notice which describes as precisely as possible the reference data you will provide to the Study Team. If you plan to be a CoI please describe which kind of landscape type you are interested to investigate, if any. For both PI's and CoI's please describe also which processing and DEM generation method(s) you want to use.
We hope that this initiative could be of some interest for you and we will be pleased to answer any question that might arise.

Sincerely yours,
Alain Baudoin (CNES) and Manfred Schroeder (ISPRS WGI/2 Chairman)
