Q: In the search field are different options to refine my search. What do these things mean?

A: Please find below the descriptions of the different options to refine the search:

Data Range: All images within the Kiosk are imaged in a specific time. You can search for images within a specific time range (i.e. only images from April to June 2009)
Linear / seasonal: If you search for images over a long time range you can distinguish between linear (all images  between start and end date) and seasonal (images from June and July in the years 2009, 2010 and 2011). Please note: the seasonal search only works if the archive contains data from more than one year.

Maximum Unusable Data: Parts of the data contains unusable data like clouds or blackfill.  You can specify the percentage of those unusable data within the image you will accept. You can investigate the real spatial distribution of those unusable data through the quicklook function.

Maximum incidence angle: The images are acquired with different incidence angles, which can have an effect on the usability of the data for specific cases. You can specify the maximum incidence angle you will accept.

Maximum sun angle: You can specify the maximum sun angle you will accept.
