INTRODUCTION 24 member states participated in the 2007 CwRS campaign. This poster presents an overview of the images acquired, sensors used, success rates and expenditure. VHR Feasibility was made for 227 VHR sites covering 157.565 km2. The area to be covered increased with 24% and the number of sites with 28% in comparison to 2006 years campaign. Half of the increase in VHR area is attributed to the new Member States Romania and Bulgaria. The success rate for the dedicated sensors (Ikonos, Quickbird), which the last 2 campaigns has been 99-100%, decreased to 97 %. The main reason for this was the cloudy weather and to a less extent the high concentration of sites. HR Sensors used were SPOT 2, 4, 5, IRS P6, Landsat 5 and DMC as usual on a first come first served basis. The HR optical imagery requested by MS continues to decrease from 4 images/site in 2005 to 3 images/site in 2007. The total number of HR sites is however still increasing; the 2007 campaign covered 227 HR sites (c.f. 192 in 2006). This year acquisitions were planned for 689 images. 97% of the images were acquired. HR SAR data was only requested by 2 MS (17 zones) and only the 1° image of the triplet was acquired due to availability of HR optical imagery.

HR OPTICAL IMAGERY
90 % of all HR optical images are acquired by the SPOT family
The bad weather in the late spring/early summer is the reason for failed acquisitions (DE, NL, UK. SE)
10 windows were closed before window end without acquisition due to availability of VHR dedicated or aerial photography.
However, in many cases VHR & HR windows are overlapping images are often acquired on the same day and duplicate imagery have to be purchased
